Many of us fortunate enough to be exposed to the miracles of vacuum clamping would encourage you small shop owners to find ways to enjoy this part of technololgy.
Vacuum can be a clamp, a vise, a lifter, a veneer molder, a router clamp and many other things to a small shop and with little more than a vacuum pump and or a good vacuum cleaner.
Here’s a pic of a large sheet handler using vacuum technology. One guy can handle 100 lb sheets all day long and not get hernia.

Roper, I figured you would be inspired and make one of your own.
Or maybe just a vacuum fence for your router or a small table to hold routed templates etc etc.

That’s a commercial example.

Lee Jesberger uses them all the time when veneering. To give him a straight edge and to cut cieces.

I’ve never brought the vacuum down to the shop floor. It currently is on the second floor with the veneer table. But I do have a second vacuum pump so i might hook it up.

It’s funny you post this today, Bob. While waiting for some finish to dry today, I was monkeying around with the dust collector hose and a large dust fitting, to see how large a piece of 1/4” plywood it would pick up. Don’t really have any use for a vacuum lift, but there’s no such thing as sitting idle around here. And I have been digging up plans for making a home made vacuum press.

I think what is going to please most of you is how little “vacuum” is necessary to lock down a project.
With a little foam and a few holes in some MDF your can have a rock solid sanding station for instance.

If you are plagued with moving large sheets by yourself you can make a simple vacuum attachment that will lock on to a sheet and them allow you to scoot it around your shop effortlessly.
The amazing thing is you can do this with the power of your household vacuum cleaner.!!!!

I’m in the same boat as Roper. That won’t fit in my shop/garage either. Too bad because I bet I could pick up both cars and create some more valuable shop space.

On a serious note, great suggestion Bob. I would like a vacuum chuck for my lathe.

Trifern, here’s a mounting plate I have made for one of my old lathes;
.

I picked up a vacuum from a used printing press and made this adapter to hook the vacuum to the head stock of the lathe. There is a bearing riding inside a piece of PVC pipe and the copper fitting is glued into the beraring so the adapter dosen’t rotate.

Here’s what it looks like hooked up.

Here’s a bowl attached to one of the face plates.

Cheers
Bob

I was just thing about this subject the other day – I was considering the One-Way system, but unfortunately my spindle/shaft thingy does not have a screw end to connect the vacuum pipe to the lathe.

Now you have inspired me to re-think the coupling method. I did consider connecting the vacuum pump directly lathe and spinning the vacuum pump at 3000 RPM, but decided it would be too difficult to hit the stop switch at that speed – and I was too lazy to reduce the speed every time down to 500 RPM.

Serious question Bob. How is the copper pipe fitted/fixed to the spindle. If glued, then obviously a permanent fixing.

I am guessing that the black plate (with wing nuts) is the “BRAKE” to stop the outer bearing from spinning? or is to hold the whole assembly in place in lieu of glue?

Hi Tony:
The thing is really a simple design and I am going to improve it when I get a chance.
I used a short length or pcv pipe and trimmed it out on the end to receive a bearing.
I epoxied the copper tube into the bearing. The copper tube is slightly smaller than the hole in the spindle shaft so just sits inside of it.
I placed a large diameter “O” ring over the copper pipe to serve as a seal between the bearing and the rear surface of the spindle shaft.
It is pressed up tight with the wingnuts and a cross member to hold the chamber in place.
When the lathe is turning, the bearing and copper tube rotate in convert with the spindle and vaccum is present from the chamber attachment.

I think I could come up with a better set up but for now this works and costs nearly nothing.
Any changes would cost time and I am short of that right now. <g>

I saw Lee’s vacuum system and built my own and it works great.

Hi All;

As Bob said, these vacuum systems can be adapted to many aspects of woodworking. Just a little thinking can inspire jigs to help hold, pull or push almost anything.

And it’s instant. No waiting at all. I can’t imagine trying to work without it any longer.

Lee
