That's a great idea! Thanks for sharing how you make those. I've been wanting to get a vacuum setup on my lathe for a while now, have to make some of those when I get setup
Nice quick and easy chucks. I made similar chucks but instead of using face plates, I recessed 1" by 8TPI nuts into the base plate. I drilled a hole just big enough to force the hex nut in and epoxied it around the edges to achieve air tight fit. Cheaper than using face plates and they work fine. I add a bit of Teflon tape when I thread them on the spindle for good measure. I usually pull 25-28 inches of Hg here in NJ.
Great ideas. The only thing I would change would be to use wooden tapped faceplates instead of metal. Since I have the Beall tap, very cheap to have whatever faceplate I need. Thanks
Hi sir! I know this is from forever ago, but I was following these steps and I believe I made a great chuck! Unfortunately I could never get above 3hg, do you know how powerful of a compressor you were using? Mine is at 2.6 CFM at 90, and is supposedly powerful enough, but I am really struggling. Thank you in advance for any tips!
I believe the system Carl uses is a venturi-style system that utilizes compressed air. If you have an air compressor that can keep up, they work fine, but small compressors (e.g. pancake-style) can't maintain sufficient air pressure and are constantly cycling.
Thanks Carl nice work, i was wanted to make a few myself. Anyone wanting a real nice cheap vac system should look up the Frugal Vac Chuck.guy. He has the best deal i have ever seen on real deal pumps and all the fixings. Also dave uses a real pump to do all that turning not a venturi system. I wouldnt recommend doing green turning on a venturi system.
Hi Carl, thanks for all your great videos. I was given the older hold fast model (black - V810R), and I bought the hold fast adapter. I’ve got it all set up, and when I put my finger over the lamp rod sticking out of my headstock it goes up to - 20Hg. But I can’t get it to get any suction without putting. My finger directly over the end of the lamp rod. I built a chuck following this video, but no suction. For the life of me I can’t figure out what’s going on. I used silicone. It doesn’t even go up a little, there is NO suction without putting my finger over the lamp rod. Any idea what could be happening / where / how I could be loosing suction?
Why not use shorter screws? Then you don't have to cut the ends off the screws. If you use your silicone cement to stick the foam to the ring, you won't need to saw off the textured surface. Silicone is very good at making airtight seals that fill small gaps. Also, the vacuum will probably compress the foam so there are no air leaks anyway.
Carl, I know this video is old, but it is very relevant. Thanks; I needed that simple learning information.

Glad it was helpful Lowell!

Thank you Zac! They really are handy
Excellent idea! Thanks for sharing Carl!
Thank you Heath!

Cool project. I think I'll make one and try it out! Thanks!
Thanks! They really are handy.
its great to watch you work, Carl. Thank you very much
Thank you very much Victor!
Nice looking vacuum chucks Carl!
Thank you Erik!!
great idea !! i will wait to see how this is work !!!
Thank you Annikas!
Great tutorial Carl, the home made chucks look to be very effective......all I need now is a vacuum chuck! ;)
Take care mate
Mike
Thanks mate! Ya they're really handy.
Take care,
Carl
Thanks Carl for this great info . nice video
Thank you very much Simon!!
This was very helpful ,Carl ! Thanks for sharing .
Thank you very much!
Carl, thanks for sharing this very informative video.
Thank you Marshall!
That foam makes an interesting sound when you cut the center on the lathe 6:36 ;) Those will be nice to have!
Hahahaha Ya they're really handy Ryan!
Very nice. I will share with my wood turning club, Central Virginia Woodturners.
Thank you very much Alex!!
Seems like a good solution
Thanks Mike!!
Very good idea there! Nicely demonstrated Carl, thanks :-)
Thank you very much Matt!!
great info. I would like to make one but don't understand how the vacuum works.
Sorry Graham! Here's a link to the follow up which I go into more depth.

great job Carl. I think you live by my motto why buy it if you can make it.
Thank you Opa! :)
God job, nice video! 👍
Thank you!
Great ideas. The only thing I would change would be to use wooden tapped faceplates instead of metal. Since I have the Beall tap, very cheap to have whatever faceplate I need.
Thanks
Amen! I made the faceplates for my Frugal Vacuum system out of hard maple, using Rubber Chucky gaskets.
Good job Carl
Thank you Jacques!
nice work
Thank you very much Ibrahim!

Hi Brandon, there must be an air leak somewhere, the compressor is plenty big enough. It could even be a crack in the wood.
Thanks for sharing Carl, I'm going to try this..... You don't show project pictures of other peoples works any more?
Thanks Tom! I share pictures on my Q&A channel :)
Sorry if it has been mentioned before, how is a vacuum achieved in the fixture?
dejanira2 you attach a shop vac to the back of the headstock

Carl,
What species do you most use for segmented turnings?
Thanks for video! Going to try this! What is the blade size in your band saw you using to cut the foam?
Thank you Phillip! I believe this was a 3/8" blade.
Would plywood coated in shellac work instead of mdf? I don’t have any mdf scraps in my shop. Home Depot is two hours away from me.
It should work if you really get it sealed.

Thanks Joe, I'll check it out.
hey Carl im with the other guys Ive never used or watched a video with vacuum chucks how about a primer for those
Sorry about that...here's the follow up,

Thanks carl. Sorry to be so ignorant but what do you use a vacuum chuck for??

Great info Carl. Can you put a vacuum system on any lathe?
Take care my friend and do a kindness
Mark
Thank you Mark! Yes as long as it has a hollow spindle.
Take care my friend,
Carl
Good job.
Thank you!
After you put the screw in and you removed them, you can grind of the points before you drive them back in so they will not stick out
Have you heard of monkey foam its a thin foam from Hobby Lobby works great.
Thanks John, I'll check it out!
That sucks lol . Great idea . l just did the vacuum system .
:( You could probably still use a few of these
Thanks again Carl. Appreciate all you do! Something else added to my "to do" list.
Thank you very much Donald!
How do you sharpen lathe tools?
Here's a link to a video, th-cam.com/video/OPhRk8g1iuA/w-d-xo.html
make it site is down

I didn't have shorter screws on hand, and the thinner the foam is the less vibration you'll get.
Hello carl
Have a Nice day
(first ! :o) )
Hi :) You have a great day too!
tried to visit make it matter
could not get in said I needed username and a password.
Not a clue what they want
Merci
Thank you!
Holdfast link is dead
Thanks I'll fix it.
Carl Jacobson thanks
What happened to showing how it works?
Why do you need the pvc pipe, why not just glue two mdf pieces directly together?
You need to get away from the head stock so the bowl doesn't hit it.
th-cam.com/video/uU5Dm083E4E/w-d-xo.html
You showed how to make the chuck but what about the vacuum system?
Here's a separate video Mark, it might help. th-cam.com/video/kcLSL_LUzGU/w-d-xo.html
@@CarlJacobson Thank you !
😢最后也没看明白这个是干什么用的。
not gonna show vacuum set up? Kind of pointless to show 1/2 of the system.
bbc?`big black
Great video but someone with a $10000 lathe shouldn't be making a chuck.
Thank you, but I make things all the time!! That's what I do lol
