I thought I'd share few pictures of my homemade vac machine. I didn't follow any particular design, it's just built out of stuff I had lying around and the form follows the function. The tools used are circular saw, jigsaw, hand-held router and battery powered drill. I had to name it something so I chose the name Qvack, from vac and Quack.
First the vacuum table. As you can see there are no supports for the table. I believe it's thick enough not to need them.
With "vacuum-cleaner" motor. There are similar motors are inside many vacuum cleaners.
Plastic holder installed. Note the drawer-rails I use to slide the holder up and down. Much easier than building rails from scratch but I have to be careful not to load them sideways.
Materials for heater. Metal shelf and oven heater elements.
Heater built (the heating element still needs to be securely fastened.). That element is about 1300 watts.
Finished machine (although this kind of machine is never finished ).
Second pull, the first was utter failure.
Body from third pull. Still needs more work.
