EIB & Centurion: Left Side Split Rivets and Strapping

As I get closer to my goals of trying to get EIB and Centurion certification, I'm starting to go through the parts of the armor that need improving towards that goal, and also for a better fit.

One of those areas was the left side closure.

  • Using the original ANOVOS system, one rivets three H&L straps to one side of the closure and uses H&L tape on the other side to secure it, giving a wearable, removable closure.
  • When I did my closure, I modified the straps by cutting off the H&L pads on the straps, and then riveted them on both sides of the armor, making them non-removable but truer to the armor used on screen.
However, even during construction things were not up to snuff. As was pointed out to me back then, my rivet placement wasn't exactly correct. The problem originated from starting with the kidney plate, where I even spaced the rivets along the kidney plate. This causes a problem with the ab plate, which has a ridge that separates the cod piece from the ab plate proper. My placement resulted in the lower of the ab plate rivets being on this seam. For accuracy, this rivet should be above the seam, with the center rivet spaced evenly between the upper and lower rivet.

A picture from the original post that illustrates the issue.

In addition, after more than a few troops, it occurred to me that the canvas used with the ANOVOS kit has no give or stretch, meaning that if there's a bigger gap between the two plates, it's not going to be as easy to compensate for than with elastic. Further, the straps were held in place with the split rivets. If I had to replace them again in the future due to wear and tear, I'd have to redo all the split rivets again as well.

Resolved to correct the rivet placement and redo teh straps with less gap, the first step was to order some new split rivets, which I did through a member on whitearmor. Once those arrived, it was just a matter of removing the old split rivets and the attached strapping.



 I used a set of needle-nose pliers to un-set the rivets and pull them out without damaging the armor. Once that was done, I had three clean holes on either plate that I needed to seal up with ABS paste. I did this by taping up the front of the plate and filling in from the back.



I wish this would have worked better, but I ended up having to do some front fill as well, and then the typical sanding with 150 - 350 - 600 wet - 1500 wet until the fills were smooth as the surrounding plastic.

I could probably do this in my sleep now,
I've done it so many times...

Finish with Novus 3, 2, and 1 to make everything shiny again. No I have a pristine surface to make new-accurate holes for my rivets.


 I used the following measurements which I followed from USKWrath's post on the matter:

Ab plate:

  • Top rivet: 20mm from top, 10mm from plate edge
  • Bottom rivet, 10mm from cod plate edge, 10mm from plate edge
  • Center rivet: halfway between top and bottom rivets (~63mm either way), 10mm from plate edge
I then put corresponding markings in the kidney plate for the spacing, 10mm from the plate edge. The markings are shown here:



Measure twice, cut once, they say. After satisfied with the measurements, it was time to cut drill the new holes and fasten the rivets. After scuffing the heads with some 150 grit sandpaper to prepare them for future painting, I put them in place using a snap head set, mallet, small chisel, and flat punch tool. For those who aren't familiar, there are six rivets total - three in the ab plate and three in the kidney plate.



You'll note that the rivets were fastened without the strapping in place. This was done on purpose. Taking a page to the common way people fasten garter loops to the inside of thigh assemblies, I decided to fasten the new strapping directly to the inside of the ab and kidney plates using nothing but E6000. This way, the straps would be easy to replace in the future. I used some spare 2" black elastic strapping left over from when I redid my thigh garters. I started by gluing them to the kidney plate, waiting a day, and then gluing them to the ab plate.



As you can see, the results are pretty tight. the bond is strong, and the straps are tight yet stretchy, allowing for a better fit and some give if I end up bending in an unusual manner.

I would have actually placed the bottom strap lower, but I have to leave room for the strapping that secures the kidney plate to the butt plate, as that uses a H&L tape system. Plus, the belt helps keep the pieces together around this area.

After all was said and done, I carefully painted the new rivet heads with Testor white enamel paint.

I also had an issue with the cod strap coming off its split rivet, so I redid this rivet as well, using some scrap ABS to make a large washer so that the hole in the elastic strap wouldn't slip off the small washer included with the rivet set.

And then I had to re-redo it since I reinstalled the strap upside-down.
But you get the picture.

Another recent mod I did was thigh fit. Remember how I lost a bit of weight to fit into my armor better? Most of that weight came off of my stomach, but some also came off my thighs. The problem was that, with the thighs already shimmed, the pieces are actually a little bigger than my thighs now <facepalm>. So what I did was add some foam padding to the inside rear of my thighs to keep the fronts f my thighs against the front of my legs. This resolved an issue wherein the drop-down boxes on my belt kept getting caught on the upper front edges of my thigh pieces, leading to issues walking (thankfully the drop-downs and thighs didn't suffer damage). I haven't decided it it's worth the risk of removing the thigh shims to make the thighs better, but so far I'm leaning to leaving them in, so long as they don't affect the armor's overall look too badly.

Next up on the list is adding a hearing assist system to the bucket to help with, well, hearing, but especially when I run the new blower fans. I plan to run both fans and hearing assist from a new USB battery bank instead of having to worry about AA batteries. Stay tuned...

Industrial Velcro and Rebuilding the Belt

This is a long blog post that covers a couple of troops and related modifications and repairs as a result of wear and experience.

To start , I participated in a great, giant troop with the OC Squad (and other Southern California Garrison members) at the OC Zoo in the Irvine Railroad Park. There were about 50 members there between the 501st and Rebel Legion, as well as a few anchor characters like Rey, Vader, and Kylo. It was a lot of fun!


(With celebrity (pig) Kevin Bacon!)

It was a great troop, but it was a bit warm. I'm glad I had some spare white duct tape in case of emergency, because the ANOVOS H&L tape on my shins just couldn't take the heat. After the fact, I had a mess to clean up between the crap H&L tape and the adhesive from the duct tape.


To clean up, I used orange oil, Simple Green, and finally rubbing alcohol to prep the contact areas for some new industrial strength Velcro that I purchased at Home Depot.


After the clean-up, I cut the Velcro to the proper length and width, I carefully placed it onto the shin closures.


I've trooped in it once since then at San Diego Comic Con; we went even though we couldn't get passes for the con itself, because there's a ton to do in the Gaslamp district outside of the con - plus there was a 501st photo shoot Saturday morning for the Imperial Sands Garrison in which I wanted to participate, so it was the perfect excuse to troop! The shins held up very nicely, even when I had to run to the photo shoot at the con when I almost ran late trying to find it.

The serious photo

The fun photo

The really fun photos

My pauldron with a vinyl sticker I had made for the event. I ended up needing to use extra tape as the heat the previous day caused the edges of the vinyl to curl.

Trooping the con made me realize that I needed to replace the H&L contacts in my thighs and shoulder bells with industrial Velcro as well, as they were starting to separate from the armor. I removed the old H&L tape, cleaned the armor like I had for the shins, and then put in the new industrial Velcro.


The snaps for my thigh garters were slightly bothersome too; if they end up not working after this Velcro replacement, I may try to adjust the snap tension using some pliers, or modify it to be more in-line with a "traditional" belt garter system.

The other casualty was the floppy ANOVOS belt. one of the lower Chicago screws tore through the belt. I'd planned on eventually replacing it with a Rob Kittell belt from www.imperialissue.com, and it seemed like now was the time, especially with the annual squad photo shoot coming up this week and an opportunity to get pictures for my trading cards.

I had previously planned to shim my ab armor to fit around my girth, but after measuring my belly some weeks earlier to plan for this project, I was disappointing with my physical fitness. My wife had started a daily workout and nutrition regimen a couple of weeks earlier, so it was then I decided to join her for workouts in the mornings and to start watching my portion, especially carbs. Within a month I had lost more than a couple of inches form my belly, making shimming he abs completely unnecessary. This was also good because I wanted to get my ab sizing straightened out before ordering  the new belt, to ensure I had a belt the correct length.

I ordered his standard 40" belt online and it arrived within a few days - great turn around for flat postage. The belt was as advertised, at 40" with an extra 10" of overlap for the Velcro closure in the back for a total of 50". It has two canvas layers sandwiching a plastic center that gives it a lot more rigidity than the canvas-only ANOVOS belt. This also makes setting up the belt for ANH Stunt easier as the holster is only supposed to be fastened to the belt with two rivets/ Chicago screws instead of the four used by ANOVOS, which would be more inline with the ANH Hero trooper instead.

The first step was to lay the new belt out and mark where all the new holes would go for the snaps (to fasten the belt to the ab plate) and the rivets (to fasten the plastic ammo belt to the new canvas belt). I covered the inside of the belt with blue painters tape so I could mark up the tape - it would be easy to punch through with leather punches and remove before fastening snaps and rivets.


I started with the center at exactly the 25" mark , 1.5" from either the top or bottom as the belt is 50" long and 3" wide total. This would mark the rivet for the center of the ammo belt. From here, snaps were marked metrically at 17cm from center; the end rivets for the ammo belt were 20cm from center. I'd worry about the two holes for the holster closer to final assembly.

Next it was time to cross the Rubicon and remove the elements from the old ANOVOS belt. Knowing that the rivets fastening the ammo belt to the canvas were terrible to remove, I decided to at least get the ammo belt off the canvas by simply cutting it off the belt, being careful to avoid the elastic of the drop-down ammo boxes. I also had to do this for one Chicago Screw for the holster as it was incredibly torqued and refused to unscrew until I had removed it through cutting and was able to holder the other end with pliers.

Yeah, there was no going back now.

So now was the "fun" part - removing the old rivets from the plastic ammo belt and removing the cover caps from the front. I've read horror stories from the ANOVOS builders FB group and also seen UKSWrath's write-up on his belt. I'd also heard that some people weren't cursed with a crazy amount of pink epoxy and were able to remove the rivets and caps with relative ease.

Unfortunately, dear reader, I wasn't one of those people.

From the onset, I could tell that the caps were glued on with a large amount of pink epoxy (the smell of it reminds me of the stuff used in dentistry to create molds or fasten crowns to teeth). The first thing to do was to remove the rivet on the back of the belt using a Dremel. I used a cutting disk to care a cross into the rivet head so it could be easily remove with pliers and then ground down more.


You can already start to see some deformation in the ABS in the shot above right. Lamentably, in a situation like this, it's not about removing it without damage, but mitigating the amount of damage required to finish the job, to make repair easier.

I hit this epoxy with everything I had, from a butter knife like UKSWrath used, to a heated putty knife, to a cutting disk (this was far too risky and may have caused even more damage), to a sharp knife (I abandoned this for risk of personal safety) and a hobby knife (the blade wasn't long enough and the textured grip was causing too many scratches). I did the best I could, but in the end I had to pry up the last bit of the cap and rip out part of the ammo belt to get them off.


The center cap is always the hardest for anyone given the lack of space to attack the cap from the side. In the end the ammo belt backing was deforming so much that I cut relief cuts into it from the back to mitigate damage. Obviously this left a big chunk missing that would need to be repaired with scrap ABS and perhaps even paste to ensure the cap covered up any other blemishes.


Out of all of this, at least eh caps were removed without breaking, as those are more difficult to repair. I just had to take the Dremel grinding tip to them and clean the epoxy out from inside the caps to ensure they had enough room for whatever mounting hardware I decided to use.


It was a dusty job. Remember to wear a mask folks!

With the caps cleaned out, it was time to start repairing the ammo belt. So I dug into my ABS trimmings and found some pieces to CA glue on to the backside of the ammo belt. I clamped them into place for about 10 minutes to allow the CA glue to cure (I don't currently have any Zip Kicker).


After the glue cured, I went in from the front and filled in the craters with some spare ABS paste from my thigh piece rebuild. That was it for the night, so I decided to let the paste fully cure before resuming work the next evening.


The next evening, I spent an hour sanding down the ABS paste smooth and then polishing, with the help of 100-150-350-600-1500 grit paper (the latter two wet) and Novus 3 and 2. Still some light scratching, but otherwise not bad. The perfectionist in me could spend another hour removing all the light scratches, but I needed to finish tonight to give the E6000 time to cure before Saturday.


I had punched the belt holes (using leather hole punches) and put the snaps on the belt the previous night: I simply used the General Tools Brass Snaps and Fastener I used for the snaps on the ab plate, but the female counterparts on the inside of the belt, again with each snap 17cm from center on each side (34cm total). The new belt fits exactly like the ANOVOS belt, but it's obviously more rigid.

For the ammo belt, I fastened the center using a standard leather rivet with a washer on the back of the snap, to give it more support. I fastened the rivet backwards, with the rivet head on the inside of the belt, as this way was far easier to tap in given the shape of the ammo belt. The bonus is that the rivet head is far less likely to scratch my armor than the rivet back.

For the ends of the ammo belt, I used tow of the four Chicago screws from the hostler, since it was only going to need two of them for the Stunt mounting. I chose Chicago screws for one reason: as a stretch goal, I might alter the costume to support trooping as a Heavy Weapons Trooper (HWT), which don't have drop-down ammo packs on their belts. Using Chicago screws will allow me to unfasten the ends of the ammo belt to easily slip off the drop-downs if that ever happens.

When finished, the assembly was as good as new, on the new belt.



Now it was time for the holster. The first thing to do was remove the two extra holes at the top of the holsters. I measured 2.5" from the top of the holster and cut off the remaining leather, leaving only two mounting holes for the Stunt mounting. I also measured center-to-center on the bottom rivets to get the spacing correct for the belt holes - the measure is 5".


For the belt holes, UKSWrath used different measurements for his holster holes, but I opted to use the ANOVOS belt measurements and fasten the holster slightly higher using a 3/4" measure from the bottom of the belt; this also gives the rivets more purchase on the plastic stock inside the Kittell belt (this should NOT affect being able to apply for Centurion status). Because I had almost exactly 7" between the edge of the ammo belt and the edge of the Velcro, I decided to split the difference and give 1" from either side, which still put me very close to the ammo belt but not too close to the Velcro.


I marked the holes directly on the belt using a pen and very small marks, put the holes into the belt, and mounted the holster. You can't argue with the results - A very clean, strong mounting with all the pieces secure and fit for ANH Stunt CRL.

Edit: when using Chicago screws for the holster, try to use blue thread locker, which you can get form most hardware or auto parts stores. This will keep the screws from becoming loose and falling out, since it's hard to torque them down without deforming the flat threads (which also might cause them to scratch your armor).


Lastly was replacing the rivet caps on the ammo belt, this time using some proper E6000  in case of future maintenance. Before I did that, I CA glued the caps of the Chicago screws onto either end of the ammo belt, to keep them from floating off if I ever need to unscrew them for possible future HWT conversion.


After the CA glue cured, I carefully placed E6000 on the back of the caps and glued them back into place, about 1.25" from either edge to get them as centered as possible, with perhaps 1/4" at most away from the edge of the ammo belt for the caps on the ends.


So I should now be set for this Saturday, and one step closer towards going for EIB and later Centurion certification. For the latter, I still need latex hand guards for the rubber gloves, but I'll source these later as to spread around my purchases. I've already ordered more split rivets to correct the rivet spacing on the left side of the ab armor. Both will be covered sometime in the future on this blog. Until then...

Time to Suck In That Gut

I started strapping the torso armor last night. But before I talk about that, I'll talk about the ab button plates and shoulder straps.

I used to paint miniatures. Admittedly, it's been a while. Here's something I did more than a decade ago, mashed up from parts, with some custom sculpt added, and painted by yours truly.


Painting these round buttons was a little harder than expected due to the rounded edges, but overall, I think I did a good job for freehanding it. Not my best work, but certainly not my worst.


Mind you, the edges will need to come off a bit, especially on the four-button plate, but I'll worry about that when I mount these pieces to the ab plate, which won't be until after the strapping is done.

But let's talk about the shoulder straps next.

The reinforced shoulder straps came out very well, and flush on the bottom.


I measured 4 bars plus the first front bar, just to be on the safe side to have enough in the back. It looked great on fitting, so I marked where the the straps would lay and scuffed the chest plate on those areas, as well as the length of the straps that would cement to the plate. Then I applied cement and clamped.


I unclamped them after two days, and the look great. They're nice and flush on the armor, even with the reinforcements.




NOW let's talk about strapping the ab plates.

I connected the three split rivets on the ab plate to the straps already joined to the kidney plate. Because I ended up covering both the "mistake" holes on the cod plate with AB paste I also connected the groin strap to the cod after I drilled a new hole in the code 20mm from the edge. I forgot to take pictures of this, but the cod looks great, like the mistake never happened. I'm just waiting on some Novus 1-2-3 to bring back the mirror shine after I sanded with 150, 350, and 600 grit sandpaper.

After the split rivets, it was time for the easier stuff, namely putting on the ANOVOS H&L straps. Besides replacing the straps on the left side with the full split rivet treatment as described in the 501st Stunt CRL, I'm currently trying the ANOVOS strapping system until I need something better, as laid out in the ANOVOS instructions.

I came up with a system for putting on the H&L tape. First, I marked the area where the tape would rest using a Sharpie, and scuffed it with 150 grit paper. After sanding, I cleaned the area with rubbing alcohol, which also removed most of the marks, but left just enough to easily help me place the loop end of the H&L tape, cut to just the correct length.


Although I didn't have enough time to get the chest and back plates before needing sleep, I was able to get the lower torso done, as far as the ANOVOS instructions go at any rate.



One thing I realized is that, at least with the test fitting, my pudge causes the bottom of the armor to pop away between the ab and kidney plates. I need to lose some weight, or at least get a shaper until I can shed what little weight I want to lose, which is mostly on my lower abdomen :P I've got a basic shaper, but I ordered a better one due in by the weekend, so we'll see if that helps.

Next on the build comes the chest and back plate. Until then...
