View Full Version : Home-made bowl holder

G'day all,

There were a couple of threads earlier this year about some home-made bowl holders. One was perspex (I think) and another ply - basically 2 circles with holes cut in 3 or 4 spiral patterns so the distance across the centre changes as you rotate the 2 circles in different directions.

Can someone please help me find those posts or at least tell me the name of that kind of holder (I'm thinking jacobs or johnsons or something like that).

As you can see I'm pretty new to turning, but would like to make one of these. I've tried searching :D for the posts but not knowing the name makes it impossible.

Thanks,
Adam

Don't forget to take some pics & start your own thread, it doesn't matter that it has been done before, show it off anyway.

Yeah, I must admit I usually get three quarters thru a project then think "I should have made some photos of that.."

Hi Andy,
That's a good article (it was among the links that Cliff posted earlier). After reading thru all the stuff I found I think the general consensus is that a chuck with 6 holders, (and 6 slots) is preferable.

I was wondering whether anyone had made their own grippers instead of using rubber stoppers etc? and whether they had worked?

I was thinking something like a 1 inch cube of mdf with a face or two (or more) cambered at, say, 30 degrees with rubber glued on it to enhance grip.

Something like this:

You could buy them for not very much, I got a set of longer ones for my Cole jaws but I can't find them now, I thought I got mine from Gary Pye. :think:

The ones that come with the Vicmarc bowl jaws are the best.... the red ones on this page but they aren't listed as a spare part.

The tricky part about making your own, is making them identical. Any deviation in shape, or even the amount of tightening among them, will clobber centering. For best results, use the tailstock for initial centering, then snug the bumpers in sequence across the diameter, as with car wheel lug nuts. Wrap duct tape, or filament tape, across the back of the chuck to further secure the piece to the chuck for insurance. Continue using the tailstock until the last moment when you trim off the nubbin receiving the live centre. DAMHIKT.
