Small rotator

[Drains]

Had to knock up a small rotator for a job. The rotator's built from a cheap rotating table plus 3-jaw chuck with an electric motor and step down gearbox, powered by a 24v variable supply, also cheap. Do note though, it was a laddie at work did most of the rotator, I just fettled it a bit - credit where it's due and all that.

The earth assembly shown is a couple of bits of brass with some pencil lead as a conductive lubricant.

The job was to build up aluminium bronze (guess how much 5 kilos costs, people), over a grooved blank of EN19. After normalising the part will be machined up, one feature of which is that it will be bored out removing the EN19 from the centre, leaving the ally bronze as the wall - effectively making a part of three pieces joined together - EN19, A/B, EN19. The A/B is non-magnetic, and this is a magnetic controlled valve body, requiring a non-magnetic section. When it's machined up i'll post pics.

Rog, ta for neatening this up

Cheers Woody. Of course I only took pics of the worst one

I like it. you cant beat the quality of weld you can lay down using one of these, wish I had more reasons to use the one I built

 

[Durara]

yep, Good job!
and i'm sure it works very well.

Cool little machine, I've always meant to make one myself but i'm lucky that my mate has one i can borrow, his has a foot pedal to control speed which is handy.

thats a nice little job si, and a nice bit of welding, not tempted to get a W/C for Lorch?

Update on that welding and machining - a better pic of how it started, followed by a lovely one of the valve machined up and components fitted. If you look carefully, you'll find the bronze.
