Building a milling machine
NormanV:
Nor do I just a lathe and a drill.
NormanV:
How frustrating! The weather has been good for the last week and I have been able to make castings every day. Today it is wet and windy and I am getting impatient. The forecast for tomorrow isn't too good either, it looks as if I will have to wait till Tuesday to get started again. It's probably not a bad thing though, my sand was getting a bit dry and I had a couple of moulds drop out as I turned them. I damped the sand down yesterday and the delay is allowing it to settle down again.
I have spent some time this morning making patterns for the pulleys. I am planning to use multi-groove belts as one of the pulleys is going to be quite a small diameter and a vee belt would struggle to get around it.

Norman,
My routine used to be, knock out the sand from the moulding box onto a swept floor, water with a watering can, cover with pvc sheet and leave over night, then give it a good turning over with a shovel the next morning adding more water if needed, then return it to the storage container (where it was reasonably sealed) via a suitable sieve ready for next time. When I get set up again I'll make a muller.
I've been known to have it turning in a cement mixer with a large gas flame impinging when I've over done the water :lol:
Arbalist:
Looking good Norman!
NormanV:
Thank you Arbalist.
Andrew, I need to do that. I have been putting the sand back into its storage box without tempering it and it has gradually got drier. I'm trying to be tidy!
