I just recently purhased the Venturi Vacuum System Press kit from VeneerSupplies .com and came up with this housing design for a number of reasons I would like to share w/ my fellow Creekers.
The system calls for 3" schedule 40 PVC tubing. I increased this to 4" tubing. The larger your reserve tank is the less your system will kick in to revive itself. Yes it takes slightly longer take chare the system but if you increase your vacuum pump generator to a 9cfm you won't even notice.
Which is exactly what I did.
The base carrier has 2 interior wall supports providing an interior channel where the vacuum lines can be ran through the unit, instead of ontop of the unit for the appropriate connections therefore removing them from possible damage. In addition, by doing so it enables you to install a handle
for carrying, which also prevents having to lift the unit by the tanks and possibly creating an eventual air leak in the system.
The entire system ended up costing me approx. $350.00, which is pretty cheap for a system that can achieve 1800# of vacuum per ft.
Vacuum Bag Secret
Premade vacuum bags are outrageously expensive.
I oupt to purchase a sheet of DuraMax vinyl and inquired as to if the product could be fused together by means of heat.
The answer I got was, they had no idea.
So, i put it to the test & came out w/ positive results.
Take your sheeting & trim it so the sides & bottom are sqare & even.
Next, run a length of blue painters tape approx. 1 1/2" from the outer edge where you are going to seal your bag.
Take a clean rag which is almost soaking wet with Acetone and wipe the exposed egde which is to be sealed.
NOTE: ONLY DO ONE SIDE AT A TIME.
Remove the tape at this point and ever so carefully joint the edges together and press together w/ your fingers. Both edges have to be completely pressed together w/ no air bubbles or voids in between.
Take 2 pieces of flat bar & sandwich / clamp the material between the bars w/ approx. 1/8" of sheeting protruding/exposed.
Take a soldering torch & begin to run the flame over the exposed edge of the sheeting in full length strokes. You dont want the material to catch fire , only begin to melt together and create a fused seam.
The ideal seam should be approx, 1/16" thick. Practice this metod w/ a scrap piece of material until you can create a proper seam.
Let completely cool & remove bar clamps.
Repeat this method for the bottom of the bag.
After proceeding w/ this method on my bags I pulled a vacuum and once the system achieve adequate suction I left it attached for 1 hour.
My vacuum system never turned back onto revive itself.
No more having to wait 24 hrs for cement clue to cure.
