This was the first one I built, the chamber is a bit smaller and the hot-zone only 30mm diameter, here it is running at 2000c

I'm an idiot, bear this in mind when you answer my stupid question. If 2200 is hot enough to melt titanium, what is the main body made out of so it doesn't melt? The hot-zone is a 55mm diameter flat graphite element suspended in a tungsten housing, this acts as a reflector, this is in the middle of...

Ahh, nice one. I saw your furnace then your username and figured there had to be more to it. Hit Google with your username and as expected there was other interesting stuff to see. I'd not got so far stalking your projects as to find out you'd actually got the casings made up and just assumed you'd...

So with that clutch cover, is it a plug/pattern for sand casting? What allowance do you have to give for shrinkage or can the cast part it be machined to final dimension afterwards? I read up a bit on this years ago in the product tech section of an industrial radiography course but other than some...

That's one I've been working on for years. I started a business making furnaces and heaters about 3 years ago and it's got in the way of my bike building.

They do look nice...bet they are a bit spendy.... Thanks, they are expensive at £7250 but a lot of time and parts go into making one, my Japanese agent sells them for twice that, it's hard sell in Japan without an agent. If I could get my website working for me, perhaps I could sell more direct to ...

I can't afford the time (money) to make one for myself, it would be nice to play around melting titanium or platinum into graphite moulds.

The Japanese use them for annealing 2" silicon carbide wafers amongst other things.

This is the six one I've made, they run at 2200c in argon gas or 2000c with vacuum. It's not finished yet, it will have a linear drive to open the lid. Designed and manufactured out of my garage/shed.
They've all gone to Japan, mainly Universities, they do like making things hot over there!

I'm building a barbeque at the moment, out of stainless, it will double as a forge with a water cooled tuyere to blow air through ( lidl airbed inflator)

It's almost finished, I got it laser cut and folded, I just needed to bolt/weld together, shame I've missed the summer.

Hi Guys, Chris here, from a little village outside Hastings. I'm an old bloke with a nostalgic craving to do the forum thing again, I'm bored with facebook now. I have so many project on the go but I started a business three years ago (non-motorcycle) so I've barely turned a spanner since. I will fo...
