Foundry sand working machines Mullers

[oldgoaly]

I know some of so called internet experts say it's easier using green sand? I don't see that! Do you just "eyeball" your sand or do you using a test kit? the type that generate acetylene gas? yes I have one of those testers even a full can of the "active ingredient" (don't remeber what the chemical is but Union Carbide made it) Also if you mix too much oil you get lots of smoke, not so with water. DA uses motor oil which works, I just think the 2 stroke is ade to burn anyway probably not going to leave any residue that could cause problems in the finish or ruin the sand. Oh I forgot to take a pic of my sand fluffer (sometimes I think I spend way to much time reading old books, The fluffer is supposed to replace some shoveling while tempering the sand, still haven't used it..
I bought a chip wringer of ebay for 20-25$ spent 125$ in shipping, I tacked some metal to make it handle sand, tried it, works, since have broken some of the temporary tacks, needs to be moved back to the main shop to be welded properly and a couple of mods. Basically I wanted to have a set up I could cast a couple of days and then in between real jobs make the casting fit what they are for.
