More CNC lost foam patterns

I drew out and cut the latest patterns with my CNC table today. They are to be lost foam patterns. The aluminum will vaporize the patterns as I pour and should take the shape of the patterns.

I cast one of the cross slides today. I didn't bury it deep enough in the sand and the force of the aluminum caused a blowout on the top corner of the part but it didn't ruin the casting. I'll just cut it away and use it.

That to-do list under your casting looks wicked.

Thanks for pointing that out Art. I have retaken the photos with that list removed. Most everything on that list has been done anyway, no need to come over to help with it.laughingicon

Gadget, I worked for 3 years at an aluminum foundry as a machinist and QA inspector. Your castings look good.

Are you using sand or what, for your molds?

Thanks Mikelleen,
This casting was done in loose sand using the lost foam process. Just bury the pattern in the sand, tap around the outside some to pack it in a bit and pour onto the foam gate.

I machined the other side of the casting today. Everything fits nice and flat. Next step is to add the clamps.

How long before you complete this project?

This is going to take awhile Keith. I've got so many things backed up I may have to slow down a bit on it. I estimate I'm not quite halfway done.
I have to get the blower working next for the furnace. The bearings on the blower I have now are failing. Without the blower no furnace, no furnace no castings.
