My cheap (like around $15) mini-vacuum table I made in like 3 hours... and it works great. </div>

I needed some small rounded clear plastic disks for a costume I'm doing and I couldn't find them anywhere - so I decided to make a mini-vac table and make my own... And since it worked out quite easily and was very cheap - I thought I'd show ya'll

<div align="center">Supplies I used:</div>
•1"x.5" wood (a couple bucks)
•1.5" x 1.75" wood (a couple bucks)
•plywood (a couple bucks)
•small shop vac (I had one and so should YOU.)
•toaster oven (thrift 'em for like $5 - or get a cheapy one from Target for $25)
•aluminum "L" rail (a couple bucks too)
•some hinges... (guess how much.. a couple bucks...)
•screws, nails n' glue (you should have those too, right?)
•styrene sheets. I get mine from Iasco - since they're only a few miles away from me. They had the exact size I needed (7x10)... they ship, but you may find a local supplier.

Simple box made from 1.5" x 1.75" wood frame and plywood bottom and top. The dimensions of the box are 8"X10". The smaller plywood on top is just under 6"X8". I drilled holes in the top surface every 1/2 inch.

A hole is drilled in the side just big enough for the vacuum hose to fit in snugly. I glued and nailed each piece together and put glue around the gaps to make it air tight.

The 2 frames are made from 1" x .5" wood and hinged together on one side. I put another hinge on the other side but only screwed it to one frame. The other frame has small nails in it that I can latch the holes of the other side of the hinge over to lock the frames shut.

I riveted some aluminum rails to the inside of the toaster oven to hold the wood frame.

A piece of styrene is placed between the 2 frames, locked shut and placed into the oven.

Heating the plastic until it starts to droop down - be sure to take it out before it sags too much that it touches the bottom of the oven and starts a fire -whee..

Plop the hot plastic and frame over yer vac table/buck with your vacuum hose in the hole and the vacuum on. Press down on the frame with your hands to get a good tight suck.

All done.

Hey, very nice mini vac table. I have one of those toaster ovens that never gets used... hm.......


thanks for sharing.
 
Good work. I made my first vac box in a similar fashion using produce crates and aluminum perforated sheeting for the face. Works like a charm.
 
That is sweet. i keep tellin myself im going to build one but it always comes across as too overwhelming for someone with no electric skills :unsure But this seems very do able for really anyone who has decent carpentry skills such as myself. Thanks for sharing.
 
Wow. I was contemplating building an el-cheapo vacuum form for some pieces I need to make, but put it off due to cost. But, seeing as how the pieces I need to make are pretty much exactly the same size as yours, this looks like it'll actually work for me

What thickness is the styrene sheet you're using?

.040 is what I used here. I haven't tried anything thicker yet.

The droop was probably about 1" - 1.5" before I pulled it out of the oven. Basically about 1/2 way between the frame and the bottom of the oven.
 
Nice job. Vac forming is easy, and the mini-vac table is a nice start. My first one I used an Sunbeam indoor electric grill, a box, with pegboard on top, and a shop vac. Worked like a charm.

www.tk560.com/vactable4.html is what I am using now.

Makes me want to go make one too. I have plenty of projects I'd like to do that requires a vacformer.
