Jam Chuck Flavours

[Grahamshed]

There seems to be a wide variety of Jam chucks made and I guess most are made to order at the time of need but at the Axi Nuneaton show Phil Irons was using one to make a gorgeous hollow form (vase) that looked ( from to far back ) to be a wooden container much like a cookery cake tin lined with foam sliced like a collet. I wish I could have got a closer look but it was bedlam there on the Friday

Basically any jam chuck you make has to be a close fit to the diameter of the project and then has to be "sticky" enough to get some purchase and yet leave no marks and come off again easily. That's why the foam. People often use router matting cos it has a bit of give and its really non slip. I sometimes use those kitchen dish spongy things for screw chuck backing to stop scratching when doing fruit etc.

Doesn't matter what you use as long as it holds the work securely without marking it.

That is correct. There are some odd jam chucks that can be used over and over but they tend to be where people make the same things on a regular basis. Like the one I post not long ago Here

I once used one of those "Kitchen dish spongy things" on a jam chuck. I then spent another day re sanding the inside of the bowl to remove the blue stain that I got from the sponges dye rubbing off on the inside of the bowl. I think the router matting is a much better idea and it is very cheap from poundland (£1)

You're kidding! :lol:

In all seriousness, thanks for the heads up - hadn't thought of looking there.

For a bit of luxury I saw a vacuum chuck in operation at the Detling show. Very nice and I was surprised at how powerful it was. £240 though.

I am tempted to ask how long the eggs took to hatch
