I am looking at making a vacuum chuck. There are not many made in this country and those that are are extremely expensive. I have a few ideas using bearings mounted in wood, long tubes etc.and, no doubt, the odd piece of string here and there.

I was wondering if anyone had any experiences of designing, part sourcing and building such equipment. I bet Penpal (Peter) has made a few.

Cheers,
Frederick

I made my own years ago& it worked well enough. I mounted my bearings in corian. I’ll see if I can dig the photos out & post them. I bought a vacuum pump after using a vacuum cleaner for a while.

Have replied twice only because I forgot something this cold spell freezes my brain:funny::funny::funny:

:funny::funny::funny: You're not the only one Derek. It was -3 in the workshop today and that's with an oil heater on as low as it will go. I did do some turning but after a couple hours gave up. My brain froze as well. Hopefully all this virus rubbish and rotten weather will pass, then we will all feel better.

Cheers

OK Bill, if you find the pictures I would like to see them. I am going to seat the headstock bearing deep into a wood plate which will have been varnish to make it less porous. Hopefully the bearing will be airtight enough for it to work.

Use a sealed bearing. I can’t find all the photos but here are some. I’ll put photos of my system up when I take some.

Never made one, and don't know very much about making one, but I do remember reading once upon a time that vacuum cleaners aren't necessarily the best way to go. I think it was something to do with the way they suck, as opposed to creating a true vacuum. I can't really remember to be honest, and the wires to the dark recesses of my brain get more frayed and worn out with every day that passes, but it could be something you might want to google.

You are right about a vacuum cleaner not being suitable for a vacuum chuck Phil. It can’t be used on a closed end which a vacuum chuck is when it is holding the timber. You can drill a 3mm hole in the nozzle end of the hose to allow a small amount of air to be drawn in by the cleaner. It works to an extent but not as efficiently or safely as a vacuum pump.

Can I just ask what sort of stuff you would turn that needs the use of a vacuum Chuck?
William I use my vacuum chuck to turn off centre & to do tilted turning. I use it to remove chucking points & finish the work. I can also mount a finished piece which has no chucking point to refurbish the piece. It saves making numerous friction chucks & jigs especislly when working to a price. It is an excellent piece of kit as far as I’m concerned making things easy for me.
I’ve turned quite a few bowling woods without chucking points quite easily & safely.
