Making a Longworth Style Chuck 

Nicely done. Good to see you actually use it.

I've watched several of these longworth chuck videos, and they all have the same problem the center hole is just slightly off and it catches a bit or the disc's seam out of round. You need to rough out the blanks on the bandsaw or jigsaw, then screw them together near the outside edge, mount you faceplate in its final place. Then mount it on the lathe and true up the edge. Now put the drill chuck in the tailstock of the lathe and drill your center hole all the way through while it is on the lathe. It will be exactly centered. Then take it off the lathe and mark and route the slots leaving the faceplate on the back. Everything will be dead-on center without trying to get the faceplate reentered again.

Great video John. A lot of accurate work required there. Well done!

Great video 👍

Very well explained John. Many thanks. Mike B

Great easy to follow build John. I've used mine more than I thought I would so I agree it's well worth making one.

Very nicely done!

Great, well presented. I'm off to make one in the morning.

A very well presented "How To" video John. Well done mate. Cheers Mike

Great video John, you have inspired me to make my own. Thanks.

Great video!

Nice job John. I attempted one myself a couple of years ago and it was, frankly, a complete disaster! maybe it's time to give it another go. Thanks for the vide.

Love it John great video.

Very impressed with that Longworth chuck John it looks great if you have the time and wood I will cross your hand with silver as I have been looking for some think like that for myself if you have the time,all the best

good work, thanks. Fajna sztuczka, dobre centrowanie. Dla mnie super! Pozdro

Hi John. Great video, I made one about 5 years ago and use it quite a lot. I was trying to remember what it was called, came across your video, and ended up watching all of. Made me recall that it is not the easiest thing to make, and quite how Mr. Longworth thought it up in the first place😉. Anyway, I thought you did an excellent job, it all made perfect sense to me. One thing, did you locate the router, or did you cut freehand, following the lines? I can’t remember how I did it Many thanks Noel

You seemed concerned that your explanation of the marking out process might be unclear or confusing. On the contrary, I found it perfectly clear and logical. I wonder if brewer's demi-john bungs might serve for the rubber grips as you can buy them with pre-formed holes (for the airlock). Anyway, thank you for an excellently produced video. I like the Minder joke at the end (lobster) 😂

Great video and tutorial mate! 👍🍺

МОЛОДЕЦ! СПАСИБО ЗА ВИДЕО.

What are the expanding rubber bungs actually called? Not having the easiest time looking for them. Great video by the way. I wonder if you still use this patent?

Does the bolt connecting the two circles ever interfere with the faceplate screwing onto your shaft?

Nice tutorial John! How did you keep the curve accurate with the router? Did you freehand or use some sort of centre point to anchor the router on the correct curve plane? Thanks Dennis Beamish Cambridge Ontario Canada

Thanks for that John Just one thing I would like to suggest if I may When showing things on the bench it would be a big help if you had a overhead camera 8X6 Workshop did a video on his I would be making one of the long worth style chucks if I had a router but I dont

Whats the point of the second blue line

Do you have the link for the eBay grippers

Hi John Not wishing to detract from your excellent video (and skill) but why not use a faceplate and put a mortice on the other side to shape the bowl, box etc? Then invert the object to hollow it out.

eBay LINK does not work.
