Filling hollow cast

[billikenmonster]

Was hesitant about asking and starting a new topic but I’m looking to fill Kit Kong Frankenstein. It is a brittle body I think some sort of cold cast porcelain, I have to put a rod from bottom of the foot deep into the leg. I don’t want to use foam or Durams water putty. It needs to be sturdy but not warp the leg. I was thinking of bondo but I don’t like that product and I am concerned with any heat generated from a chemical reaction. Any ideas? Thank you in advance

Alumilite

Two part resin.

[billikenmonster]

Does it heat up when mixed?

[monomaster2]

Yes, But don’t try to fill it up all at one time. Just do a little at a time and that heat is negligible.

[motherhen]

Just asking, why not Durams?

I have a KK Frank myself…

[billikenmonster]

My experience with it is that it gets brittle and can crack. Since it will be supporting the rod in his leg I’m concerned it will become unstable...did you use durhams with your Kit?

[scuzzfink85]

Durham doesn't dry well in in enclosed space.

[motherhen]

I was intending to but with the concerns this thread is bringing up, maybe it’s not such a good idea.

[scuzzfink85]

If your worried about heating of alumite stick the torso is room temperature water..
That will off sit the heat.

[billikenmonster]

Alumite does sound good and the price is not bad but the heating has me concerned with warping or bulging or splitting it. I would like to go with some type of polymer I have used Aves a lot but it would break the bank. I never used magic sculpt don’t know if that would work out

I just use resin. I never just pour it in full. I pour some and coat it then I eventually fill it.
Never an issue. I did it recently with Model mansion gorn. The drawback is its very heavy now.
I also do it with vinyl kits same way a little at a time to avoid heat and distortion.

[billikenmonster]

That is a real good point about the weight ... it is a tall and leaning forward piece and I think all that weight will be a problem I think my solution may be to fill the upper torso with foam then use something in the leg where the rod goes ..,,,thank you all for your help with this

I really like that idea. Coat it a few times to give kits some strength and fill the legs to whatever one may need.

Lol over time I have become really good at it. I especially like it for vinyl kits as I never have to worry about wilting over time.

I really don't like the foam it's unforgivable and super messy.

I don't know if they still make it or remember what the name was, but there was an expanding foam for model railroaders whose ratio of liquid to expanded foam wasn't that much. All I can remember is that there was a drawing of a steam loco in black on the label... Big help, I know...

Is that the Mountains In Minutes foam?

Yes! I believe that’s the name.

[griffin]

I do not believe it is being made anymore. Heck that stuff was around when I was just a teen.

Smooth-on makes a number of expanding foams that should work.

I use Polyblend non sanded grout for tiles.
