  • Rockler sent me their vacuum clamping system to try out, so I spent a week playing around with it and learning how best to use them.

    This is a tip for anyone that doesn't know. The process in making MDF leaved a skin on both sides of the MDF so MDF should be fly cut on both side to improve vacuums holding force. As he did mention the sides of the MDF should be sealed or taped to prevent loosing vacuum. The thickness of MDF may be the same but the weights per sq/ft can be different from different manufactures. The lighter the weight the MDF the better air flow. I myself always us 3/4 inch MDF from HomeDepot and fly cut 1/8 inch off each side.

    Great overview Winston! Thanks for sharing! Instead of sealed MDF, plastic like ABS or acrylic may also work in conjunction with the double sided tape as a wasteboard. I've had success with this on bigger CNC machines, but have never tried this on my Shapeoko. If I ever get my hands on the Rockler pods, I will have to give it a shot!

    Hi Winston. Thank you for all your awesome videos! Especially CNC related. Was wondering if you could dive a little deeper in vacuum tables and see what you can come up with. You know how much time is spent in setup and clamping of a piece. Vacuum tables save so much time. I have built several myself. I use 3/4 mdf (so much dust) and create the form on the top side and then the vacuum channels (paths) on the back or second side. Use paint on the mdf when finished as it is porous. I use EVA Foam for gaskets. You can get the foam locally. It's used as mats to stand on. I use the quarter inch that comes in a roll and it's so inexpensive and easily cut into custom shapes on the cnc. I use a shop vac to create suction. I have not tried a vacuum pump yet. Thanks again!!

    Regenerative pumps/ blowers often work well. Continuous duty, quiet, maintenance free and extremely reliable. They pump insanely fast. Make any size holding jig with common thin adhesive foam stuck to a plywood jig on your CNC router etc. They work better on larger areas. For example a 20" x 20" panel will be held down with about 500+ lbs of force. On large panels add a few extra thin foam center strips to avoid bowing your panels on vacuum. Plus regenerative pumps vacuum large amounts of CFM air so imperfect seals are not a big issue. Open your valve and you have vacuum in 1 second.

    Also there are vacuum pads that have seal in groove, where it compresses, thus having no issue with leveling

  • @GENcELL2014
    @GENcELL2014 3 ปีที่แล้ว

    I'm opting for a venturi based vacuum system powered from compressed air with a secondary vacuum vessel and some valves.
    From my understanding as long as the vacuum vessel is large enough once it also reaches vacuum along with vacuum pods or fixture plate(and a couple valves are turned to seal everything including from vacuum pump) you'll have ample "reserve" vacuum force to keep everything clamped without having the venturi or diaphragm vacuum pump running the entire time.
    Watched a TH-cam vid where a guy tested how long it holds(good seals), there was still a lot of clamping force after days of just having a closed loop system between vacuum vessel and vacuum plate.
    I don't plan on using mdf, going with proper top plates that are either aluminum, robust polymer like maybe delrin, or even composites that sit on a custom aluminum vacuum fixture plate.

    Love your videos (envy you bad). How much power does the vacuum and cnc require? I got a CNC3018 from China, 24V4A power brick so 100W max, but my shopvac is rated at 1200W! At $0.30/kWh this is not very interesting here. I assume your pump takes way less than that...

    • @WinstonMakes
      @WinstonMakes  6 ปีที่แล้ว

      The Shapeoko is about the same. 100-120 ish watts max. Makita router is another 780 (maximum). Pump is another 100. But practically speaking, you'll probably never see 1kW of draw except at the instant you turn on the router.

    When you created the pocket to hold your dog tags for engraving. Could you have turned the center of the pocket into, in essence, a downdraft area. Drilled holes all the way thru to give better suction.

    • @WinstonMakes
      @WinstonMakes  6 ปีที่แล้ว

      Yes, but then the MDF itself would not have stayed put without the dogtag on top. If you used some clamps to lightly hold it in place it might work. Otherwise you'd lose your origin.

    Interesting video, but it looks to me like it's introducing more uncertainty into the workflow than it is adding value. I'm more and more leaning towards just screwing things to the wasteboard. I can't tell you how many projects got f'ed up because of insufficient workholding.

    Rather than those pods with your CNC router..... look at the vinyl gasket material and other hardware Rockler provides with the pump.

      It does seem like the hard part is the pump, not the little squares. Building those yourself seems much more likely to work well; you can size them to be exactly what you want, and you can remake the tops so they can be sacrificed whenever you want.
