Here is a pic of the finished Muller.  We found we can overload it if not careful.  Had to shorten one of the blades as it was to long.

Ferd,  yes aluminum.  We are happy with our first try.  I think we need more Bentonite in our mix as it would flake easily when dry.  We plan on trying more and improving as we go.  Making the molds wasn't to hard.  It is the pattern making that is the challange.

Hi Tom
They look great. What metal are they cast in ( aluminum ?).  Castings look clean.

Well it fianlly happened.  We made some parts from our foundry.  Mel made up patterns and put them on boards.  We tried a few to see how our sand mix would work and they turned out fine,  The part on the left is two body bolster side bearings and Mel wants to make a dummy spring pack so he made 1/4 of a spring and we cast up 4 parts to make a whole for a pattern.  Next up is to try a casting that takes cores.
We need pedistals and journal boxes.

All the parts are together but the trap door.  You can see the hole for it in one of the pics.

Next up, building the arms and the center support to hold things and turn with the shaft.  We put a hole in the base and attached the center bearing and then hooked up the drive shaft when we set the tub back on the frame.  We did watch the wheel go round and there will be a second one.  We need to ream the hole to get the shaft thru.

Hi,

We have started to build a sand muller to help with our molding.  Our first casting wasn't to great and Mel thought this would help.

We have a 24in wide by 12 inch deep tub with a thick base.  Mel found a right angle gear box (83 to 1) on Ebay and we took a motor off an old drill press.  He sketched out a frame and I started welding.  We added wheels and the gear box before time ran out.

Do you have plans to pour bronze with this furnace. I made one of the first generation Gingery furnaces but I never did much with it. I mostly pour bronze that is melted in a hand held crucible. This has worked for G1 7/8ths scale so far but I am thinking bigger in the future.
Cheers Dan

Now comes the new and exciting part.  Lighting a fire in it to warm and drive off mosture.  You can see the nice blue flame and we decieded to do it outside the building for safety reasons.
