Thread: Chucks and other grippy things.

6 days to go

Jam chuck, no tail stock support required.

Now that I am home it might be time to ring and find out what I am doing.
Is there any other sogestions for holding methods that we need to demonstrate?

Just a couple for you and , Ken. Most is probably old hat but a re-fresher course would be good:

- chucks v. faceplates
- tenon sizes and shapes
- tenons v. recesses
- removing evidence of the holding method
- faceplate sizes
- screw lengths and number
- wasteblocks
- using ply as wasteblocks - failure?
- hot melt basics
- strength
- removing it
- tail stock support basics
- crush chucks
- jam chucks and best materials

No doubt there are many, many others.

Jeff, I thought this was only a one day event.

John, this can be reversed using a jam chuck without tailstock support. Because of the shape a little more time will need to be spent making the jam chuck. A good subject for Sunday.
What size is the bowl? I will try and bring a piece of scrap big enough to reverse it.

And in between there is the talking eating and Robbos cups of tea, so not much time for actual demos
