Toaster Oven Thermoforming

Forming some ABS. Thin pieces are difficult to hold for milling or routing with a trammel. They also waste a relatively large proportion of their material, so I decided to form them with ABS and heat!

What! No words? Can't wait to see the project.

so simple but so useful! hopefully you know you can flame polish that cut edge as well? saves a huge amount of wet sanding!

[@ScottRumschlag]

Yeah, I've also used a hand plane on plastics with good results, haven't tried it on ABS yet but I don't see why it wouldn't work.

I like the toggles on the sled.

[@ScottRumschlag]

Me too, I bought them second-hand but unused and they are very helpful, much easier and better than trying to accomplish the same thing with a piece of wood supported on one end and screwed down in the middle.

i think i see where this is going! could be totally wrong though. my thought is the abs you're molding will be teeth on some sort of ratchet, timing mechanism, and the conduit will be the housing that spins it.

Nice cooling method :D I take it there's little or no spring back? I'm guessing that's a cam for something, something moving round that arc?

[@SpeedyRK]

Very cool!

[@scotthaun8582]

the anticipation is killing me

[@fr0stb1te]

new expanding table?

[@vonantero9458]

That's what I was thinking when he placed it on the curved pipe. We'll see next week I guess :D

[@ABusFullaJewz]

I still have no clue what this is going to be...

[@sddwalker2]

I think with the shape of those wedges and the other curved metal parts then it's going to be a capstan table mark II
