    Vacuum Cart

    OK, I know this is flatwork (and quick and dirty flatwork to boot), but it was done solely in the interest of turning, so I'm posting it here.

    This is what I did for the vacuum rig in my new "everything is mobile" shop. I started with the "constant run" hardware kit from Veneer Supplies, and with the exception of a bit of tubing and hardware, it was all made from stuff I had laying around.

    When it's upright, it's sitting on four rubber feet. Tilt it back a little ways, and it's mobile on the two wheels like a dolly. I ended up using a honkin' big 4-prong twist-lock plug for the power. I was having trouble finding 220v rated 3-prong locking plugs and receptacles, but I found a decent price on the 4-prongers, so I bought enough for my initial 220v needs. (Some of my 220v outlets will be in the ceiling, so I decided to make everything twist-lock.) It's overkill, but it cost me a bit less money, and I don't think it'll cause a problem.

    The motor cover is intended to keep most of the dust and chips out of the pump, but it's held on with screws so it's easily removable.

    I piped the air and power on the back so the cover wouldn't have to work around the tubing. The conduit is overkill, but I had a piece laying around, so I used it. The exhaust is also piped outside the box to keep the heat down. I'll watch things when I start using it, and if if the pump gets hot I'll enlarge the front opening to allow more airflow. (On the other hand, I may close it up more to cut back the noise a little if the external exhaust keeps things cool enough.)

    I ended up with two different filters -- one that came with the Veneer Supplies parts kit and another I ordered from Surplus Center. I decided to use both of them, for no other reason than I had them available. The big one should catch anything that comes down the hose and the smaller one should catch any dust that might get in through the breather valve (unlikely).

    Hopefully in a week or so I'll finally be able to fire this thing up (and the new lathe, too). Dang electricians and their power trips.

    Looks really good!

    Vaughn, you are going to LOVE finishing off the bottom of a bowl etc with a vacuum chuck, just simply LOVE it

    You thought things out really good Vaughn! Looking forward to finding out how your system works, what the noise level is like and if there is an issue with heat at the pump. I do like the idea of making the system portable so you can move it out of the way when not in use. Very nice work!

    You weren’t kidding when you said you were going to reorganize. Very cool idea.

    Nice unit Vaughan, could you let me know what vacum this unit pulls.
    Is the suction hose wire or braided reinforced? and is the vacum pump vane or diaphragm? I have worked in the pump hire industry for 30 years and have used all types of vacum pump's to assist the priming of the unit and still try to keep up to date with the equipment.

    John, the hose is braid reinforced, and the pump is this one:

    Surplus Center Link

    I'm still waiting on 220v power in the shop, so I haven't seen what numbers it'll actually pull. This is my first exposure to vacuum pumps, so I'm pretty ignorant about them. This particular one seems to be pretty popular with the woodturners, so I'm assuming it'll do what I need it to do. If I ever get into vacuum press veneering or anything else where I need to maintain a constant vacuum over a substantial length of time, I'll re-do the plumbing to add vacuum storage tanks and an electronic pressure controller. Something along the lines of this one.
