Fine downfeed phase333: casting the fine feed housing

HOME


The housing pattern started out as a piece of particle board. Nothing fancy, but quite functional.

 

Here you can see how I milled away the top edge of the pattern to form a thinner section for the mounting bolts.

 

All rammed up and ready to pull the pattern.

 

R2 after the pour.

 

Ahh, the smell of burning Petrobond casting sand. Once you've smelled it, you'll never forget it.

 

Right out of the flask, ready for finish machining.
