Built a vacuum box and frame in a morning from scrap wood Couldn’t be easier, did my first form in the afternoon, had to adjust the heat, second attempt was good. See a couple of the videos above in this thread

It took a couple of days to set up shop. Definitely smaller, but I have to say it’s nice. It’ll work! The new vac-form table works amazingly well.

Looks 
good. Now you have your space. 
Im about to make my mold, have a couple questions before I vacuum form.
- what is a good temp for 1/8" ABS?
- Will the plastic stick to wood? Should I coat in poly?
Keep it under 300 and watch it to make sure it sags enough to vacuum form

no need to coat it, the plastic will not stick. Right around 300 is the sweet spot, make sure the PLASTIC is at 300, your oven may have to be hotter. I’ve gotten better results with 1/16in abs, it’s plenty sturdy too.

so then should I have the oven at ~310?
I use a space heater so i can’t tell you what to set your oven at unfortunately. Just make sure you have a method to measure the plastic temperature itself. I bought a cheap $20 laser infrared thermometer and it works for me.
I just use my eye balls… though the abs does stick too them sometimes. watch the plastic sag
@Stevemk14ebr what do you use for your space heater enclosure to heat up the plastic. Do you have any pictures.
Do you guys think something like this would work?
I think that making a box and drilling two holes for two heat guns would do the trick

why dont u use your kitchen oven?i mean the one inside your house?
Not a good idea. Plastics give off all kinds of toxins that you don’t want your family breathing or eating. Ventilation is important.

backyard grill???
Give it a shot! I actually tried that in the beginning but didn’t get good results.
Guys, do you think this would work with a “large toasting oven” which you can buy over here in the U.K. Main consideration is size inside but assuming you do like @psychotiller and make an armadillo design it could work…
Would any of you mind posting your oven dimensions as a reference?
I found some interesting threads in the model making forums about vacuum forming so will post those in the morning when back on my desktop.
I was going to buy a large toaster oven for $90, but then found a smoker element for $50 on Amazon. I think that will work much better because you can make the enclosure any size you want
