Volks 1/100 Helmine



I got this kit from Yahoo Japan Auctions by way of the proxy bidding and "deputy" service website Shopping Mall Japan in the neighboring state of Indiana. Including all the service and shipping fees it cost just over $250.

This is the front page of the typically bare-bones instruction sheet.


And here's a picture of all its 47 parts laid out in the classic resin kit part layout "pose."



I'm not entirely sure whether or not this kit was worth all the money I paid, but I do like the design which is a kind of Five Star Stories "cousin" to the Gundam known as Qubeley.



Since the kit is about 20 years old, it is a pretty bad cast. Lots of pinholes or bubbles that were trapped and hardened into the plastic resin. Some mold misalignment causing damage to details or the design of the original sculpt. Some bigger bubbles that just completely wiped out details.

Those who know me, however, will know that I (perhaps perversely) enjoy repairing and resculpting parts on bad kits to make them better. This is what I will be doing in this case, and now I will take it a step further and re-cast the kit when the parts are up to standards that should improve considerably upon the original. I don't feel like I'm stepping on anyone's marketplace toes with this. The kit is really old, as I said, and very few people even know that it exists at all.

I'm well into the repair process already and I want to share some of it with you.

First up is a youtube video of before and after work on the big shoulder armors:



Next are before and after pics of repair I did to the point of the helmet's horn which was lost in the casting process:






Here is a video of the process for the resculpt.

[Edit] BTW I just found out that I've been mispronouncing the name "Helmine." It is German (duh to self) and short for Wilhelmine so it should be pronounced as "hell-mee-nuh". It means "the resolute protector" which I think is nice.

ACen Kit Building with Kids

Put this off for too long ...

The model building for kids thing I did at Anime Central went really great. The kids all loved it and we had a great time together. Thanks HLJ!

Here's a few pics.





The staff at the con said my presentation had the biggest turnout of anything they'd done for the kids but even so the turnout wasn't huge, so I had about a dozen kits left and I'll be doing it again next year with the leftover kits (now safely in storage).

Finally figured out the foot detail casting!

After my first attempt went awry thanks mainly to resin that was well-past its expiration date, I decided to make a new mold with RTV.

Here's the mold box getting started. I've just roughly lumped in the Kleen Clay to hold the part in position so that it is level in the box, and has enough space on all sides to make a good solid mold. I've tried to estimate a good volume of clay so that as I smooth it out the level will rise nicely to just below the edges of the part.


Using this set of tools:

from here (click on the "set of 12" thumbnail, it's the better set but has no direct link), I smoothed out the clay and worked it up snug against the edges of the part and the walls of the box. The RTV (Room Temperature Vulcanizing) rubber will work its way into the smallest spaces so a good seal is necessary. After that I built up the walls of the box with another row of bricks and laid in a thin snake of clay around the walls to raise the level a little more there.


Then I added one more layer of Legos so the RTV has enough space.


Here's the demolded RTV. I didn't use any mold release, which was fine in this case. I was nervous tho' because I did that by accident, not on purpose.


For the casting, I decided to use Bondo auto body repair filler. I was inspired to do this by a Brazilian figure sculptor on Hobbyfanatics named Ryuji who uses this stuff all the time. It's way cheaper than urethane or epoxy resins and the supply is much handier at the auto supply store (casting resin is a bit hard to find, even on the internet). I did spray mold release before spreading the Bondo into the mold.


The first one I did wasn't even worth showing because the working time on this Bondo stuff is only about a minute, which came as a big surprise and ruined the first attempt. This is the second attempt:

There are too many defects in this part to make it worth using on the final product, so I tried a few more times.

Here's what I came up with. The second and fourth ones are fine.


Now I just have to trim it up and smooth out the flat backside so I can fix it onto the flat foot and the prime and paint.

Wish me luck!
