I have been very busy at work, but I read the blogs all the time.
This post here will save you a lot of greaf, pay attention and you will have 100% pulls.
Forget the boxes and shop vac's, just look at the photos.
You will need a vacuum pump, here a 2 choices,knothing else,you can find these on E-Bay
You have to build a platen, look at the photo.
A 1/16 inch aluminum sheet, keep it flat. Dimensions shown will pull most bodies
Under the aluminium sheet is a grillage sheet.
Cut the grillage sheet 1/8 inch smaller than the platen aluminum sheet.
Grillage sheet as shown
The platen block is the same size as the aluminum platen.
Cut a hole in the platen block for the vacuum fittings.
Now study the photo on top of the platen wood block is the grillage,center it on the wood platen block, run a 1/8 inch bead of silicone around the perimeter of the grillage, place the aluminum platen sheet with the predrilled 1/32 holes on 1 inch centers and sandwhich it all together with a flat weight on top. Let this cure, make sure silicone came out from all edges. Leave that alone till the next day. NO LEAKS CAN BE IN THE PLATEN
Additional fitting photo
Now here is the whole thing, A vacuum pump, hose, check valve,and the platen.
You must have the least amount loss for vacuum, a perfect world you can draw knothing more than 28 inches of vacuum, this will not happen with the table top units using a shop vac.
So save time and money do it correctly.
A very simple flip vacuum table, effective and 100% accurate.
Connection from vacuum pump
Drop the platen down on the line up pins
Almost ready
Show time
Lets turn on the heat, get 2 inch sag
Here ya go another perfect body, with a tight draw all the way down flat on the platen, lot of vacuum pull with no leaks.
Look at the bottom PETG is flat around the bottom edges
Not bad
Fresh off the popper
The mold with vent draw holes properly placed very important, dont over look this
The little simplfied vacuum table
A vacuum guage, check for leaks, you must have zero leaks
Please note there is NO VACUUM BOX, only the hose from the pump to the platen, very little draw is needed, and must be air tight.
Ask questions, improve you product, do it right ,do it once, good luck
