Me too! This is a wicked project!

Ha good question. I used to have unlimited access to liquid nitrogen so I forget things can be hard to cool. Google has no easy answer for me as to the glass transition point.

Freeze it and cnc?

For what it's worth, NapierDeltic's idea of tire rubber was a really good one!

I think Polyurethane might creep a bit at those temperatures?

Is "the right stuff" by permatex available to you? I've seen that stuff hold up exceptionally well in uses like head gaskets for air compressors. Possibly mixed with a fiber like fiber glass or carbon fiber, it would hold up? An alternative would be to have one 3d printed from nylon, if you...

Agreed. Good post.

I always just left on tripoli as an anti flux, or rouge.

I wonder if high temp rtv gasket maker might work?

Heating is complicated and BTU's are as useful to judging a torches performance as gas tank volumes on cars. Max flame tempurature, flame front speed etc... all play huge rolls in getting the heat where and into what you want to heat.

Probably a working temp around 75°c according to some generalized data sheets.

@nerd100 probably has the right idea then, going all metal.

Those couplers should have an rpm/temp rating for the spiders iirc. Unless they are random internet ones

MAPP will always be around, it's just propylene gas (same stuff they make rope from) diluted by various brands with propane. MAP or MPS gas is the good stuff that went away. It was far superior to MAPP. MAPP is the sales acronym they came up with after MPS was removed from the market.

Nice catch!

If it happens again, the old school neon sign transformers work well.

Glad it did not zap you. Would a fly back work?

Can't wait for them to arrive!

Out of curiosity, any updates?

Melt under a pool of iirc, salt.
