Re: Baking Cores

I have a 2 part resin system I'm using already. Baking is optional but I dis it to harden them up even more. I screwed up in using an old baking pan which wasn't dead flat. I was hoping there were oven safe surfaces/slabs that are good to use to maintain a true surface while baking

Baking Cores

Hi All,

I baked my first cores in the oven, but made the mistake of not using a dead flat pan/surface. I was thinking about using a pizza/baking stone to make sure everything sets right. Are there any better alternatives?

Regards,

John

Re: Driver Casting Repro

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?

Re: Driver Casting Repro

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.

Re: Driver Casting Repro

Dave,

I watched your video on the driver pattern a few times before I started prepping everything..and then a few times more when I was mixing the stuff. Top notch as always.

Re: Driver Casting Repro

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

Re: Driver Casting 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 ...

Re: Driver Casting Repro

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?

Re: Driver Casting Repro

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😁

Driver Casting Repro

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?
