A lot is said about mounting on screw chucks, I've an Axminster one for their chuck, but if you're working with a thin blank, you could cut some ply/thin wood shims to shorten the screw.
But what I've gone over too and use the most as I've 1-1/2" O'Donnels jaws (pin jaws would work the same) I drill the blank .. (http://farm4.staticflickr.com/3815/9021328634_f73a864638_m.jpg) ... then mount .. (http://farm4.staticflickr.com/3746/9019111343_081ab01d2d_m.jpg) ... true what will be the bottom and cut the mount this time for larger jaws .. (http://farm8.staticflickr.com/7422/9021345356_211ba6fae7_m.jpg) .. just rechuck and turn.. well it's my way.

Yep, I understand what you're trying to explain now.
I do something very similar. Drill a shallow hole with a saw-tooth/forstner bit. But I don't have the very small O'Donnel jaw set, however I do have the SN2 1" jaws, which do much the same.
Thanks for the post.

I use 3 or 4 home made screw chucks, with various lengths of screw protruding, or if I think its to big for the screw chucks I drill 30mm hole and use a set of sorby pin jaws instead,and if its a big piece bring up the tailstock to make sure nothing flies off,regards,

Personally I have never been happy using a chuck in expansion mode. I will invariably turn a spigot and grip it in contraction, even with wet wood I do it this way, I find it easier to either turn the foot off or shape the foot as part of the design. Doing it the other way you tend to end up with a horrible mounting hole that no matter what you do to it it still looks like the hole you made to mount it on.

Hi John,
Very valid point, but for as often as I've used it I've not had any problems, with this form of mount, having drilled it, it is only the initial step, I used the larger recess this time at the base, which was turned away to obtain the finished size, it also gave better access when the tail stock was in place to remove when reverse chucked.

I very often use a screw chuck or drill a 25mm hole & use pin jaws, but ONLY when turning bowls or vases etc, in which case this is all removed later anyway.
