Mud Lathe
#2
Took a photo of the crucible while I was outside and i have a few minutes before I have to make pizza.
Finished (and used) crucible.
   
340mm tall. Those with some foundry experience will no doubt foresee the problem I was setting myself up for with this...

Anyway..
I had to refresh all my sand as it had been unused for over a year, it was bone dry. Must make a muller one of these days.
I had to make a new casting flask big enough to cast the throwing head in. The pattern was in about a hundred pieces. First time I rammed it up, the sand fell out of the cope as i lifted it off the drag. second time i rammed it up, when I separated the cope from the drag I found that one of the rim pieces had shifted.
   
Third time went okay except that one of the sections between the spokes collapsed. I decided to go ahead with it and machine out that section after casting.
The large flask holds the throwing head mould, the smaller flask has a slug that will be a blank for one of the bevel gears.
   

More later.
