Q: What else do I need to buy to get started?
A: All neccesary fittings and tubing are included with each press. All you will need to purchase separately is a Vacuum Pump. If you plan to plumb directly to your vacuum pump we recommend adding a Check Valve to prolong the life of your pump. The Automated Vacuum Control System includes one in the kit. We also recommend getting an Extra Membrane for a backup.
Q: What CFM vacuum pump do I need to operate the HD Press?
A: All HD Vacuum Presses will work with any 3-CFM pump. We recommend the following pumps. Based on what you are pressing you will have to decide which will work best for you. Robinair 15800 VacuMaster 8-CFM Two-Stage Vacuum Pump. Robinair 15500 VacuMaster 5-CFM Two-Stage Vacuum Pump. Robinair 15310 VacuMaster 3 CFM Single Stage Pump. Be sure to check out our Automated Vacuum Control System for a fully automated streamlined solution.
Q: My HD Press won't hold vacuum when I close the valve. How can I troubleshoot and fix this?
A: Check the membrane for dirt and clean it with a damp sponge. A dirty membrane can effect the seal. Check for holes in your silicone membrane. If you have formed anything with sharp edges that were not properly covered the silicone membrane can be punctured. Take the heat sink off the press, wet your thumb and place it over the port and pull a vacuum. This will narrow down where the leak is. If the vacuum holds with your thumb over the port, then you can rule out the plumbing. If it doesn't, then the leak will be somewhere between the port and your pump. Check all the plumbing connections to make sure they are securely seating in the fitting. If you can't find the source after this, please contact us for help.
Q: How much vacuum is required to form kydex?
A: Most of the time all you will need for Kydex to form for knife shealths and gun holsters is around 27inHG.
Q: Will this work for leather holster forming?
A: Yes. Many of our users are doing leather holster forming with the HD Press.
Q: The vacuum pump fitting doesn't match the easy connect NPT parts supplied. How do I make it work?
A: You will have to remove the flared fitting that your vacuum pump comes with standard and replace it with the 1/2" or 3/8" easy connect fitting supplied with your press depending on model. Most vacuum pumps are ACME threaded which is a little different than NPT. Once you remove the standard fitting it will rethread to work with the NPT included.
