This has been an off again/on again project for almost 6 months. It took me awhile to find the right oven. (One that would really tie the room together ya' know?) Then as luck would have it, I would have no way to hook it up in my shop without installing a new electrical box too...
In this order, Turn on your vaccum, open your oven, pull the abs sheet, place it on the vac table, make sure you press it down far enough to get a good seal, turn off your oven, Let the vacuum run a couple of minutes while the abs cools.
Now all that's left is to trim the fat off of your new cover.
So I ditched the 220v idea all together and pulled out the bottom element. Then I replaced it with a 110v Smoker Element that I had on hand.
I also had a converter/inverter that I could use as the switch for the smoker element.
It works! definitely gets hot enough to heat the ABS to a proper temp.
The table is really just a 1" hole drilled through my work bench with a shop vac stuffed underneath. I used some door seal molding to shape the seal around the top.
I used 5/16" screen frames cut to oven size and then clamped together over the abs sheet.
The process is simple if you keep things in order and time it the same way every time. Pre-heat your oven, place your screened abs in the oven and wait for it to sag. It'll sag a few inches below the screen frames when it's ready to form. I left an oven rack below it just to make sure the sagging abs couldn't hit the hot element.
