Project Information

For making my stave snare drums and hoops I need a very big clamping system. From HPL, 1/2 inch thick, I made 8 extensions. This extensions can be changed in turning diameter. There is a slot and also two positions for the button. The benifit from this is that i can use it for many diameters.



Cole jaw button in second position.



Cole jaw button in first position.



Centering the extionsions by turning the chuck and looking between the button and the fence.



The right speed is important! There for i use a speedcontrolling system



the extension in itself

Thank you for reading and watching

That's really cool. I had that same idea for my Longworth chuck and have it drawn out but never got to build the extensions yet. did you use steel or aluminum for your extension bars?
Wit that setup, you really need to be aware of those arms flying around when handling long lathe tools to and from the work!!

Nice job on them!! You're a man after my own heart with that idea!!...............Jim

Jim,

I used HPL (high pressure laminate) The benefit off this materiaal is that you can saw and molding it with woodworking tools !! Also screw-thread tapping is possible

Good thing the lathe is heavy or it might take off.

Good job.

Great idea, Dutchy.

...and I love the incorporated safety protection on the digital speed controller. As we all know… 'Speed Kills' ... so its nice to offer up some measure of safety there. LOL

Hmmm, thanks for this. I was wondering if I might be able to make extensions to handle bigger bowls as I get better with my turning. This looks like a very easy thing to do now after seeing what you did.

Dutchy, what speed do you suggest using? The only time I've used a Longworth chuck I did it wrong and the bowl went flying.

My chuck isn't a longworth chuck. The wood on above chuck isn't only clamped but also screwed. The speed is depending of the diameter. I always start at zero and speed it up but I never accept to much fibration.
