I'm in the midst of the final once over on the repro pattern and there's a few areas I want to address before painting/mounting on the match plate. What's the best filler material to use on the repro plastic?

Hi Dave,

The white stuff is plasticine that was used in a couple of questionable areas. I still have to remove that and give the pattern a once over before mounting

Hi All,

Here is the end result. Not too bad I don't think. I'm letting this park on the band saw table overnight to set. Thanks for all of the pointers and suggestions. Next up are the cylinders.

Hi Dan,

This pattern is made from poplar, piece by piece. Some of the joints were challenging to fit and might have some issue areas. I'm going to order the proper BCC release agent before pouring the repro

Hi fred, Yes, I should be good on the major surfaces and I did use beeswax in the questionable corners. I think I screwed up by not getting the actual BCC release agent. I thought I could skate by using a furniture polish, as did McCord on YT when he poured that Wright brothers engine, but they was ...

There were some spots where it grabbed for one reason or another. Can anyone recommend a method to check over the negative before I pour the positive to avoid future issues?

Thanks Dave, yes this will be gray iron.

Greg, I had to use 2 kwik cast gallon kits to get enough material..I made the pouring window probably by seconds..even with a few dry runs and a clean floor

Hi All,

My first attempt at a pattern and repro. Next step is to pour the 8002 again and get the plastic pattern. Thoughts/comments?

I spoke with the foundry owner and he said they do 6 tons per melt, and therefore shouldn't be concerned. Here is the wooden pattern. Still have to sand the fillets and pour the repro.

Hi All, I've read from several sources that its not a bad idea to provide the raw material to the foundry in addition to the pattern. With that said, can anyone advise on where to get pig iron? I was also considering as a last resort grabbing a few cast iron skillets off of Amazon/Ebay if there's no...
