pirmin:
realy nice castings so far.there are model engine casting retailers that care much less about their stuff than you show in your first batch from this foundry! they realy seem to know what they do in the foundry.

Guys, thanks for the compliments and suggestions. I think my foundry uses green sand and air set for the cores, but then I'm not sure. I tried to cast the water jacket at home in aluminum, and it was a disaster.

Soon I'll be posting all the fun I'll be having machining the exhaust cage. It has a lot of set ups and holes that have to align between the setups. I have been thinking of how to hold the casting as it has an odd shape. Normally I'd make a base tool to hold it, but I'm going to try to get by with just a vise first. I have the port and bottom squared up so far.

Oh My, I am several weeks behind on my posts. Too much fun in the shop and garden. I know it's a bit early for some folks to get their garden in but here in Texas you have to do it early or it burns up. Everything is blooming and I have lots of baby tomatoes and tomatillos on.
So, to finish the exhaust cage. The side hole in Photo Ex Port 3 will be plugged. It's needed internally to complete the port geometry. A core would have been ideal, but that would have been a second core for the part. The top geometry was made with an external core.

maury:
This the completion of the Webster Chicago hot tube version. I have been waiting for months to get castings for the Igniter version for this engine, they(mostly) have finally arrived. The Post Office lost some of the parts after having destroyed the original package and re-packaging the remains. This will be my next focus in the shop.
