Longworth Chuck

[CHJ]

Has anyone else made one of these with more than four studs?.
If so do you think it a worthwhile mod.

Main reason for asking is that although in theory more holding points would be better, the sharper arcs required to fit eight in would mean a higher "gear ratio" on the scroll and I think possibly less easy to adjust/clamp.

Made this one by the way just so that the routers would stop pining. :lol:
(or was it because someone asked why there were still so many in the tool cupboard not being used)


Back Plate is made out of 18mm ply with a tapered socket to fit the Nova Jaws. it also serves as a mount for a doughnut style chuck.

This was made from a layout in the American mag Woodturning Design. It has 6 studs.

Thanks, that certainly looks more secure on the holding front, although I have not had anything come adrift so far in the 4 spigot version I will have a another go at similar as it can only be an improvement.
