I'm leaning toward making my own Cole Jaws, and then saving up for a Longworth-type set-up. Has anyone here made their own Cole Jaws. Found these plans online, and of course there are several YouTube videos in the search-hit list. Tips?
Well I made a miniature version the other day for a special project. I only had MDF scraps with Formica on them to use. Not the best choice but worked fine for this project. I made the screws adjustable so I can raise or lower them to hold different work.
Thanks, Tom. I've used those rubber bungs for other things, so am familiar with them. Do they "squish outward" for micro-adjustments when you tighten the screws?I did something very similar to those, but I used plain MDF. I also used black rubber bungs that I picked up the local Ace Hardware to use as grippers. I have a few left if you need a sample.
OK, go ahead, make me envious.😉I rarely use it since I started with the vacuum chuck, but it worked fine.
Jamie, I have a beater Grizzly chuck that I put some alum. plates on. I then screwed wood pieces onto these. I tighten the jaws down on some spacer strips and turn an opening to fit the piece that I am working on. I then remove the spacer strips and can tighten down on my workpiece. I do have to replace the wooden pieces occasionally.

I made a Longworth first, but recently made a set like in your link. Actually several sets for custom screw locations. Instead of buttons, I used angle brackets (up to 2" x 2") with short pieces of vinyl tubing on the upstanding legs. I use them most;y for jumbo donuts. I used about 3/4" cabinet-grade plywood for the jaws, and regular cap screws to attach to the scroll chuck - with washers to avoid crushing the wood.
I've also made cast lead jaws for cheap eccentric turning. Similar cap screws with short pieces of brake-line tubing lining the screw holes.
FWIW, you can use different button radii for eccentric turning too, on any Cole jaws. Usually, only 4 or 6 buttons will match the offset circle.
