you're a saint!
I have no intention of trying cutting with the set up, just mentioned that as that's were I'd seen it done.
Inherited a set of sapphire gear recently so might try that with different nozzles - any suggestions ( clean ones please 'cos I'm shy
) on types / availability/ recommended places to get etc ???
Got some reflective bricks but was considering vermiculite as had heard you can pack stuff in it ( ie fill the barrel if / when it gets made) to retain heat? I've also seen the ceramic wool used to great effect to retain heat and it's not too costly.
