We currently use only Black HDPE 1/2" thick for all Longworth and Doughnut Chucks

The outer diameter of the disks for this chuck is 19.375"


When dealing with chucks this large a little run-out or wobble is natural simply due to the HDPE plastic material used in its construction and the sheer size of the assembly spinning on the lathe. HDPE is practically indestructible and tough as nails but it is plastic and as such subject to some movement. This could be due to changes in temperature or simply how the bolts are tightened. I've never been bothered by it but some customers have been. If you are prepared to accept some minor wobble and work around it, you will be amazed at this new improved version which rolls two popular types of chucks into one unit. I re-engineered the new version so you can use both modes at the same time. It is literally the best of both worlds.
