An Essential Wood Lathe Jam Chuck

This is a how to video, showing my steps for creating a wood lathe jam chuck for wood turning. I have made a few modifications to a similar jam chuck I made a few years ago for my midi lathe. I have also included a materials list below if you would like to build the same jam chuck. Hope you enjoy the show.

I create handmade, high quality wood pieces (and sometimes, crafts using other mediums such as natural stone or acrylic) that connect to people on an emotional level. Each piece is meticulously designed to look and feel like an art piece. I have always adored art, and have an underlining mission to incorporate my knowledge and skills into wood turning. With my videos, I hope to inspire and encourage others while promoting wood turning, experimentation, and safety. Please stay safe at all times!

You even make your jigs and fixtures with a craftsman's approach👍 My dad always said If It's Worth Doing, It's Worth Doing Well. -Mike

MPart Thank you Mike! I say the same thing all the time. Lol Your dad is a wise man. Thanks for watching my friend. Take Care. -Speros

I agree that is a handy chuck and I use one of those a lot including with my vacuum chuck. It would commonly be referred to as a friction chuck as jam chucks do not need tailstock support.

[@spwoodart]

Mike Peace Woodturning Hey Mike, I’ve heard several debates on this one. It makes sense that a groove for a say bowl rim to fit into, snuggly, would be creating a friction hold without a tail stock. Thus I would call this a friction chuck. Also some suggest that the pieces are being jammed together. On the other spectrum, tail stock being used to hold a piece against a platform with say foam is jamming the pieces together. It seems Jam chuck is used for both methods, but the non tail stock method is usually called a friction chuck. Makes sense, since the piece is held with friction in a groove. I also know that even with a friction fitted recesses the tail stock is still used for safety until the last cuts, well, should be anyway. Lol I should have mentioned these deferences in the video thanks bringing this up. I appreciate it. Take care. -Speros

A useful tool for any turner. Very good idea and an excellent job done, as usual Spyros!

Kwstas Antwniou Hey! Once again thank you so much my brother. Take care -Speros

(1) For small bowls, etc., a much smaller jam chuck works well and you can turn it at a higher RPM. (2) You are getting the excessive dust because you are using a carbide scraper to cut the MDF. For the least dust, use traditional cutting tools, turn it at low RPM, and take a heavy cut.
(3) Instead of using a faceplate, at least for smaller jam chucks, you can use a tap from Beall Tool Co. to cut a thread in the jam chuck so it threads directly onto the headstock spindle. However, you will need to glue a "hub" onto the center of the disk to provide extra thickness.
(4) Jam chucks up to 8 or 10 inches in diameter can be made with a tenon that can be gripped by a scroll chuck. Glue and screw a small disk of hardwood (not MDF or plywood, which may delaminate) onto the larger disk and cut the tenon on that.
These suggestions are just to suggest options and are not intended to take away from what you did. Your video is well presented. -Doc Green, author of Fixtures and Chucks for Woodturners

[@spwoodart]

Hello Mr Green, I would first like to thank you for your suggestions and tips. You have some great tips here for me and my subscribers and I have used some of your suggestions before. I do own a ball tool and often make the threaded head attachments for smaller pieces with a little CA to strengthen the threads. I mostly use this large jam chuck for making large 16” clocks. Second, I have owned a copy of your fixtures book for years and love it. If you would ever like me to feature your book, I would be happy too. Thanks for watching and commenting my friend. Cheers!

Brilliant idea and jig mate, i have penciled this in for a future project.
Thanks for sharing and take care my friend !! Bram

[@spwoodart]

Bram the Wadesmill woodturner Thank you Bram. I’m the same way, I have a huge list of projects I want to complete. I don’t believe I will ever finish them all. Lol Hope all is well my friend. Take care - Speros

[@darrellreed7044]

Nice job! Where can I get the carpet non slip without holes??? Please

[@spwoodart]

Hi Darrell, I believe Home Depot or Amazon has them without the holes. If you can’t find them under rugs, look for shelf paper, etc. thanks for watching.
