Very nice, I actually had to look up Soffietta because I was
unfamiliar with glass blowing terms.

I noticed that you had a circle cutter. Where do you purchase these?

That circle cutter came off ebay. I wasn't looking for one at the time
but stumbled across it when looking for something else so I bid and was
the only bidder so got it for £70 ish. It's a Keetona made by Keetons,
who are still in business, but they haven't made them for over 25 years
apparently.



I found a website that shows how to make the cutter and I might end up
having to do that.

I thought that it could be made from a few rear axle shafts from a
truck.

I have seen the James Riser site so know the design, Lots of ways to do
it, the axles should make a beafy unit. Mine will cut 1.5mm steel but I
think having done it I will limit it to about 1.2mm. It also won't go
below about 4" diameter. Having a fly press though I can punch smaller
sizes. The other day I made a punch and die from mild steel to punch
some plastic circles about 1.5" diameter, it worked quite well on 1mm
copper and aluminium as well.

The other item I spun on my site is the soffiettahttp://www.metal-arts.co.uk/soffietta/index.html. In brass they require
1 or 2 anneals depending on size. The worst I have done for anneals was
an item like a trumpet cone about 6" OD in about .8mm brass, it took
about an hour total of which maybe 10 minutes was spinning and 50
minutes annealing, probably about 12 - 15 anneals.
