Hey guys I wanted to let you know about my blog. So here it its:
http://manbehindthecanon3.blogspot.com/
the only issue that I have w/ it is the fact that pegboard isn't all that stable, it tends to break under pressure, & w/ a vacuuformer table there will be lots of pressure.
I have done almost this exact set up. Though mind had the oven built onto it with a frame to flip the plastic onto the oven and back to the work space.

To overcome the strength issue with the pegboard you can place spacers in the blank spaces between holes. Putting a hanfull of spacers works great.
I've seen a similar project done but instead of using pegboard for the vacuum table, the builder used a piece of MDF and drilled the holes by hand. He said it only took about 10 minutes but the thicker material was more stable and less likely to buckle under the force of the vacuum.

One could also take three sheets of pegboard, glue and laminate them but you'd have to be careful not to plug the holes with glue. By the time you cleaned out all the holes, you might have been better off just using the MDF.

Still, I now REALLY want to build a vacuum former.
I was thinking the same thing. I'm also designing a semi automated vacuformer for myself. I'm planning on using MDF for the framework & stronger woods for the vertical frames.

Sorry if I ask a stupid question but like my one teacher used to say 'He that does not ask a question is dum' but anyway what is the use of the wooden box? I mean like what does it do? I dont understand. I also want to mould stuff. But is the box that you made just to put the mold on while in the oven?

Yes it is, I stapled the plastic to it and then put that piece in the oven. Then I placed the heated up plastic over the mold and turned on the shop vac.
Very cool! I like that the project is inexpensive and explained very well. That mask is very nice too.
