Resurrection of a CFEI 100 KVA Induction Furnace
awemawson:
It is amazingly sticky stuff. As soon as you get it on your boots you start accumulating stuff and the going gets heavy. By the time you walk over the pea shingle you’re REALLY weighted down !
It all hoses off though thank goodness
vtsteam:
Andrew, I expect to see some molten metal from that vicinity soon! :beer:
awemawson:
One can but hope Steve !
In all fairness it already has done a brass melt since it’s resurrection but only small quantities. My welding shop floor has a load of 100 x 6 mm strips 6 meters long waiting to be made into flasks when I get my “get up and go” back, but movement is a bit painful at the moment.

Andrew,
Just a thought, I have quite a large collection of wooden flasks, I don't do any "series production" casting, which means that I make flasks almost every other casting as needs differ.
Cheers, Matthew
awemawson:
Matthew yes basically that's what I used to do for odd shapes but I like to have a stock of 'standardised' boxes that will mutually connect vertically and are ready 'on the shelf' for quick jobs. I had loads but it seems I gave them away!
For my wooden boxes I used to use sash window locking catches. Boxes were hinged at one corner with the catches at the other, so with sodium silicate set sand I could release a block of set sand onto the moulding floor and hence need less copes and drags.
Here are some 1" diameter piston moulds and cores that I did that way some years ago
