Thanks NB4M! I used to be a photographer (still a hobby) and my old Nikon 990 has a great macro feature (it allows me to focus down to a 1/2") and has a manual focus reticle in the view finder so that I am able to selectively choose where the camera focuses. Glad you're enjoying it - nice to know people are following along (makes the effort worth it). Although I was hoping that some of you who have this kit would build along so I could steal some of your ideas! On to the signal assembly itself! Again, there is the typical sanding and filing of the edges to clean the part up a bit. I shortened the legs on the side "fire" indicator so that it sat next to the main signal a little closer. I also filed the shape of the side markers a little bit to be closer to the line art. Now there are conflicting line arts (if you look at the reference drawings I posted earlier in the thread) - but I just picked an choose which shapes I like better. Again, there's a little excess resin on one of the triangular paddle like signals which is very easily remedied by a file and some sanding. Now if only someone can make white decals for these paddles that follow the line art! There's no way I can paint that small - but it would look great! Anasazi... are you there? I also started to add little extra bits of styrene plastic here and there to more match all the little sensor gak all over the signal. Here you can see a breakdown of the pieces showing the elbow piece that connects the signal arm to the signal assembly itself. Actually, I choose to invert the piece instead of using Gundamhead's instructions - because I wanted the larger end towards the arm, I believe it should go from big (base end) and taper to small (fragile) at the signal end. Additionally, if you look closely, I also drilled a 1/16" hole in the bottom of the elbow (the larger end accomodates this more easily) so that it can take the excess brass rod poking out the top of the arm. This provides a near friction fit and is a more secured attachment than just crazy gluing it to the top of the arm. I then started to detail up the signal itself - I wanted it to look more delicate like in the line drawings. On the elbow, I used a square file to file down the end of the arm so that it looks more like a pivot. I also drilled very fine holes with a pin-vise to mount antennas as per lineart. I happen to have very fine styrene rods which I used for the antennas, but I was considering fine wire or stretched sprue (a process where you melt the plastic sprue and stretch it to form fine antennas) but being the lazy sod I am, I just used what I had lying around.

Now comes the joint portion. I filed flat the mating surfaces to make sure we get a tight fit and get rid of any extra resin that might be in there. I'm not exactly clear the exact orientation of the pieces - and its hard to discribe in words from the instructions. Do I lined up the brass rods and it made sense that the two bigger squared ends lined up. It doesn't really matter too much in the end which side the L-shaped joiner piece is on anyways - there are no real "canon" line art that says either way. After fiddling around for a bit, I chose the following orientation - I think it made more sense when you have the pieces in front of you than to try and decipher the instructions (word problems where never my strong suite ) Now I've noticed that after sanding, some of the surfaces had a few bubble holes which appeared. Instead of filling and sanding, I thought it was easier to just cover them up with a strip of styrene glued over top of the affected area.

Thanks for the kudos all! I'm sure there'll be another round of casts. Personally, I'm hoping that they do a reduced version with just the upper part of the arm and claw/fingers assembly - I didn't realize how big this baby really is when its all together. Ok, I got a good chunk of time today! On to the signal arm. The first thing to do is trim off the excess brass rod that was embedded in the two parts of the signal arm. Look for the two ends that look alike, a larger square section with a smaller rectangular section with a space/slot detail running up the center. I would leave the excess brass rod at the base connector end and the signal connector end alone for now so that we have something to mount to. I just snipped the excess with a pair of pliers, and ground the extra down on a rough file the same way I did for the two parts of the main arm. Then I cleaned up the casting on the arm - there are some expected seams the run the length of the arm. A flat file was perfect to rough down the main areas (I don't mind sanding down extra - its filling in holes with putty and sanding that I hate! ) it also was the perfect thickness to get inbetween the slot and file the interior a little bit to get rid of some of the flash. On some of the other hard to get to areas, I used a x-acto knife and scraped it first. In the end, I sanded everything down with a 200 grit paper to get rid of any filing marks.

Okay, I didn't do too much today... I only pieced everything together - and it was the first time I had the arm and magnets holding the whole thing up. I am proud to say, that the two magnets did its job - it is very secure up there. I think the resin claw fingers or the wrist pivot joint or the three contact points between the Valkyrie and backpack will break before the magnets give up its hold on the Valkyrie. Hence I used 5min. epoxy on all these critical areas, and used a lot more than I needed - I gooped extra around the joints, but most of them are pretty hidden, so I do think it comprimises the overall looks too much. Wow! I never realized how long this arm was! It can be half as long and still work. Maybe it will allow some type of retraction mechanism like a ball bearing kitchen drawer hardware be used if there were a hanger to retract into?! (that's maybe another project some time in the far future) Maybe that will be Jesse or Gundamhead's next project - build a hanger for this - we could use just the claw portion to hang another Valk inside waiting in line? hint, hint... I don't know how I want it displayed now - originally I thought it would be neat to display it vertical, but its so cool hanging horizontal too! I can't wait to paint it! Thats when it will come alive. I think its time to assemble the signal tower next, tomorrow. I'm really happy with the way the arm has turned out. It would be so much easier if I was building a new Valk for it (most of the problems came in the retrofit portion) - I would place the internal magnets for the fastpacks farther back (but I couldn't in my case since I had place additional details in the rear opening of the fast packs that would of interfered with the placement of the magnets). Enjoy... till tomorrow...

Here's a shot of the arm/claw/fingers assembly as I let the 5min epoxy to dry. I really gooped the expoxy underneath inside the finger plate area and fingers - since there isn't a whole lot of surface area for the glue to work against. I don't think it will be much of a problem, I'll paint it black let it dissappear into shadow and plus there's a supplied hydraulic actuator that will be fitted into place beneath each of the four fingers anyways. The pencil beneath provides the right orientation for the booster packs. The only thing is that when viewed directly from above, one of the rear arms is slightly askew (because of the placement of the magnets below the fast-packs, it actually pulls the arm incorrectly. However, its only noticeable directly from above - I may deal with it later if it becomes too much of an eyesore - but I just want to get all these parts properly glued in the right orientations first. Its a lot of pieces to get the angles right - work slow and carefully.

Here's a shot underneath the claw with the fingers friction fitted in place and the central umbilical shaft glued in place. I find that the entire assembly was a little askew - wasn't entirely symetrical along either axis. (Again this can be fixed by grounding off the resin pins to the central sensor piece between the two finger plates - but I personally don't feel that its worth the effor) This isn't a huge problem since its such a complicated shape that its difficult to decern this unless you are looking at it straight on or from the top. So I glued the umblilical shaft assymetrically towards one end to further hide the fact that its not perfectly symetrical. I find that if you purposely postion items assymetically, it can hide symetrical problems

Remember I accidentally over-drilled and drilled a hole right through when I was mounting the wrist to the upper arm? Well, I found the perfect part to hide that mistake in the Wave Option parts (the same one with the minus molds). Here's a shot with the part glued in place and another cylindrical doodad to hide some excess epoxy glue that I was too lazy to file down. And remember that I'd said it was a bit of a pain or nusance to sand the seam in recessed areas - well I'll find something to fill it up instead of sanding it down. The same part works perfectly for this portion of the arm. So now I'm getting a little carried away with using some of the extra gak I have from this Wave Option kit - I like putting these vents over the top solid portion of the finger plates because I can hide the fact the the solid portions underneath don't line up properly against each other.

I would recommend using 5min epoxy to glue the little finger tips since the contact point is actually so small - I actually let a bit of epoxy spill out the top and bottom to ensure a proper strong bond. I then tacked the little lock cylinders that attach themselves to the ends of the finger tips. There's a cool minus mold detail on the ends of the cylinders, however, I was missing this detail on one of my cylinders and had a missing chunk from the other two cylinders (which would of been really easy to fill and sand). However, I happen to have some spare minus molds lying around from a few years ago when I ordered a bunch of option parts from HLJ. I think I've found the exact minus molds that Gundamhead used for his original masters So I thought I'd cut the tips off and mount my own minus molds in place. here's a little clean up to the cylinders themselves. Make sure you maintain the little bevel at the end when you sand them - I used a self closing forcept type tweezer and a file to clean up the bevelled end.

Yeah! I'll have to separate them very carefully in the future, I supposed I won't be doing it all the time (its just nice to have the option). Good idea about filing the magnets down... for me it might be just too much work to justify the effort. The rare earth magnets are like little pieces of metal and it would take a lot of work to file them to the correct shape - additionally I don't know how much weaker they might be due to the size decrease. Just trying to rough them up to be epoxied into the claw fingers were a lot of work. I wouldn't be able to "hand" file them down - I need powertools. So, today I started working on the claw finger tips. There's a bit of cleanup on the pieces themselves, just a little sanding here and there to get rid of any seam lines or un-eveness. I also cut a little cardboard guide to the right angle based on the fast packs that the finger tips should be glued to. Its really important to get these angles right - this will ruin the illusion that the finger tips are "gripping" the fast packs if the angles are not correct. Additionally, the magnets and the strong magnetic force interferes with getting a correct angle if I leave the fingers on the fast-packs. I wanted the magnets to self-centre - so I glued them inwards towards each other a little bit - because of this, I couldn't let the fingers sit on top of the fast packs, since they would naturally be drawn towards each other a bit thereby creating the wrong tip attachment angle. Also, I was afraid that any excess epoxy might drip from the tips onto the finished fast packs if I were to leave them on the fast packs to dry.

Hey Spatula, don't be so hard on yourself. I think it looks great! Especially considering its your first Valkyrie... its a tremendous effort. The most important thing is don't be discouraged - we are all learners here, and I for one, still have so much to learn!! If it makes you feel any better, I have yet (in my 10+ years of experience) to build a perfect model - or even one that didn't have some major mistake or flaw. Plus since we built it ourselves, we will always have a more critical eye and can pick out immediately where we went wrong or what the mistakes were. The key is getting it to the point were others can't pick out your mistakes - I've given up on trying to build the perfect model long ago! Criticisms eh... (I'll reply to your PM here instead - since I think others will benefit from the comments too) well, first off - did you hand brush or airbrush the white coat. It makes a lot of difference (I can't really hand brush a smooth coat to save my life! and really rely on the airbrush to get a clean even coat). As mentioned before, I'd concentrate on getting rid of the seams - in the beginning, I'd use more putty (which results in more sanding) but its safer to use more putty and sand to get rid of the seams. It also looks like you did your wash on a flat finish paint - I see that the wash seem to have stained areas around the panel lines. The oil panel wash works well on glossy or semi-gloss surfaces - so you can wipe away the excess wash without staining the surrounding paint. Lastly, does your digital camera have a white balance setting? If it does, set it to tungsten setting, it will neutralize the orange cast in your photos to give you a better colour rendition in indoor lighting. Don't worry about stealing anything - I post here to share, and I think its a great compliment when I see others use my suggestions. Actually, I "stole" it from Tenjin the artist anyways

I've placed a large goop of 5min epoxy inside the fast packs and the magnets on top help keep the magnets inside the fast packs in the proper place as the epoxy glue dries to secure them in position. This shows the top and bottom of the rear claw fingers with the magnets glued in place with the 5min epoxy glue. This last shot shows the engine section that got damaged while trying to remove them from the fast packs. I'll just apply some Tamiya putty, re-sand them round again, and re-paint these small parts. Its too bad that it got damaged, but in the end the fix isn't too painfull and should be seamless in the end.

I traced the area to be removed for the magnet on the claw fingers. Here's a shot of the placement of the claw fingers with the magnet under it. I think I will be able to run some wires to it and "gak" it up so that it looks like it belongs. The magnets are marked so that the inner mating surfaces are always identified so that I will glue the right polarities in place. I then transfered the location of the magnet to the opposite claw finger.

I'd also make sure to carefully align up the claw fingers, they are not supposed to be at the same heights or angles if you want the Valkyrie to be attached horizontally when the arm is perpendicular to the direction of the Valkyrie. Carefully line up the Valkyrie and make sure the arm is straight and in the proper orientation to get an idea of where the claw fingers land.

Damn! pulling out the engine bell on the other side was not quite as uneventful or sucessful I think I'll be able to piece it together and sand it all down and refinish it in the end. It will be easier than cracking the fast pack halves. No decals on the engine bells! at least.

The magnet set were so strong that only one set was able to pick up the entire Valkyrie quite sucessfully. Also, I found that if I had four sets, they would be too close to each other and tended to either stick together (which would cause the forward claw finger to bend backwards to tough the rear claw fingers) or repel each other. So having the other pack with another set of magnets would be more than enough. I tried using a washer under the fastpacks to reduce the attraction - but then it was too weak - so I decide to have it a little over strong than under. I just have to be very careful when trying to separate the Valkyrie (its strong enough to rip the claw fingers out or the fast pack apart).

I threw in some magnets to see how they'd hold here. They were so strong that I don't think I'd use four of them (one per claw finger). I think I will only use 2 sets of them for the rear claw finger (one on the claw finger and one inside the fast packs) - otherwise I don't think I'd be able to pry them apart again without either damaging the claw fingers or the fast packs. As fernaris said, be mindful of the polarities - I marked the outside of each the magnets with a dot, so I know the side without the dots face each other when it comes to gluing them.

Well - the dreaded time has come to take apart my built Valkyrie. For those of you that have yet to build your Valkyrie for this arm - don't worry about these following steps, sit back, relax and laugh (thank god that you don't have to go through this!) I've wanted to use this Valkyrie for the arm for a while - in fact I was hoping for an arm kit like this to come along when I built this Valk a few years ago (worst case I was going to make my own arm - but thanks to Jesse & Gundamhead, we don't have to do that! ) So I made a few provisions to make as much of the fast packs removeable. I always like to have options. I don't know if you remember, for those of you that did follow along with my original step-by-step build up for this Valkyrie (on the old boards... I wish someday that they could be retrieved ) the rear large engine bells were one of the last things to be placed. I modified the interior mounts by cutting away a section of plastic so that I could mount the engine bells at the end which eased the painting process. Well that provision will/should allow me to extract the engine bell assembly without cracking the fast packs in half. Well, just pulling them out by hand didn't work too well - I ended up separating the engine bell from the pivoted engine itself. Probably better this way anyways, so I don't damage the very visible bell. I thought I'd wrap up a pair or needle nosed pliers and pull on the engine... There, not too much damage - the engine did split a little due to the force of the pliers, but it was only the bottom area and could easily be mended. Here you can see the cuts I made to those horizontal cylindrical pieces that grab onto and pivot the engines.

Thanks fernaris - good tip about the polarities. The boosters to Valk - I will probably end up glueing this area - I only left the friction fit because I knew I was going to need to get at these boosters individually in the near future. Gundamhead & MechTech, I realize this is a small area with only three contact points, but with epoxy on the 3 points, I think it will be enough - the Hasegawa model is really light - and I'll keep it away from small kids or high traffic areas (I don't think there would be any solutions to small kids! ) I'll see when I get it all together then - but I'm leaning away from lancing the entire thing together, however I do agree that it would be the safest way of mounting the Valkyrie. This shot below shows a better view of the placements of the claw fingers in relation to the claw assembly - I had them incorrectly placed at the bottom of the claw in the earlier pictures.

Yep - that's exactly where I want to put them. A set permanently mounted inside the top portion of the fastpacks (I built it so the fast packs do come off the Valkyrie - Hasegawa's fit is so perfect that its just friction fitted all these years to the Valkyrie) Now I just have to back out the large rear engine bells without distroying them to get access inside (wish me luck ) And another set mounted to the bottom of the claw finger section as shown in red in your sketch. My hope is that the two magnets is strong enough to attact each other through that layer of styrene plastic about 1mm thick - but not strong enough that I can't ever use the arm for anything else!

Well, that's it for tonight (its Alias night!) and the wife is home! I thought I'd do a dry fit to see how all the parts come together. I thought I'd put the magnets on the underside of the fingers and underneath inside the fast packs - well, thats the plan anyways, we'll see if it will hold.

Next, I moved onto the four claw fingers - I thought I'd skip ahead in the instructions and concentrate on the making the necessary modifications to attach the Valkyrie onto the claw with rare-earth magnets. The four claw fingers have excess resin on the top side which is easy enough to sand away along with some flash on the top edge/corners. The end tip is supposed to have a squared notch in it to accept the finger tips that "hold" the fast packs - and requires a little cleaning out with a square profiled file. Upon sanding away some of the excess resin, some bubbles appeared that were below the surface. I thought it might be neat to add some detail to the top instead of just filling them and sanding them flat. So I added some strips of thin styrene again (my good friend on this kit!) and ended up adding a square plate of styrene on one of the fingers that hid a bubble beneath - so I had to make all the other 3 the same as well. Oh, I thought I'd add some shallow circular impressions at the ends done with a pin-vise - but not drilling all the way through the resin (I've done it to all four (not shown - only one was shown at the time I took the photo).

Here are the pieces finished - not too bad eh? A pretty quick fix... it only took like 20mins from start to this end point. I also sanded the front edge to make sure that the resin ended in line with the styrene strips However, if you dry fit these plates to the other half of the plates, you'd see that the solid portion of the bulkhead (near the top) actually extends beyond the inner finger plates (assuming you keep the bottom edge parallel and in line with each other). This is unfortunate - but I tried sanding the bulkhead at an angle in towards the other plate so that there will be a slight lip when attached. Its not ideal, but its the easiest fix and as long as both sides are identical, then who is to say that these bulkheads don't taper in?! I thought I'd apply a thick coat of Mr. Surfacer 500 on the front edge just to be safe and I'll sand that down tomorrow when dry. Of course, I did a test fit of the entire assembly - very cool that it all stays together on its own - snap tight! The pistons are just placed in there to get the right angles (not glued in yet).

I thought I'd tackle the problem of the claw finger plate edge. I decided to sand down the top and two diagonal sides right down to the bulkhead. Then I'd use the same thin styrene strips and crazy glue them to the edges. I started with the two diagonal sides first, leaving them long so I can have something to hold onto. Trimming them down afterwards. I then sanded the edge with the sanding film flat on the table surface. I works easier to always sand in the direction of the glued piece - so you're not prying it away from the glued surface. I sanded the top flat so that I could glue a continuous top piece. I found it easier to have a vise hold the piece, then you could have both hands holding either end of the strip of styrene.

A shot of the arm after the 5min epoxy has set...

Here's the 5min epoxy - I assume most of you know how this works; you mix up equal parts resin and binder/hardner and mix for 1 min. I usually mix on a scrap of cardboard - and I cut a piece sprue out of the Hasegawa kit (using the numbering tabs as a spatula). Once you mix for 1 min, you have about 4-5 mins to play with applying it and setting up arm in the correct position. I think its quite important to get it straight in plan (top looking down on it) - but in elevation (side view) it can deviate a bit since there are angles throughout the length of the arm when viewed from the side. I first found a way of supporting the arm still with piling up various stuff from around the table. The steel straight-edge ruler is a visual guide to make sure the arm is straight when viewed from above, the four paint bottles makes sure the arm doesn't twist around the joint. The black bottle cap below supports the joint so that its attached at the right horizontal angle. Lastly, I fitted the arm piston in place (not glued) to get the right angle to the wrist piece when attached to the arm.
