Longworth chucks - cutting today vs. a year ago

[difalkner]

I have greatly improved not only the process but the speed at cutting Longworth chucks so I thought I'd do another video. When I first cut these chucks they were taking about 16 minutes per disc followed by 5 minutes or more per disc of hand sanding the edges to clean off the tabs and to round the edge. Occasionally the Baltic Birch would chip where I cut a tab and that was frustrating.

Anyway, it's now a fairly refined and efficient process for a small home workshop. It could be improved upon but for now it's working just fine. The tools for the entire process are circular saw to break down the BB, table saw, drill press, CNC, stationary belt sander, drum sander, and ROS.

Here's the video -

Enjoy!

Dave, how do you conect the two disks to each other?  And how do you mount to the lathe?

The back plate is mounted to a faceplate and there is a 1/4" hole in the center for a bolt to connect the two plates.  Each slot has a bolt and rubber gripper that holds the bowl or drum staves.

Here's a video showing how it goes together and how it works when on the lathe.  This is one of my customers and he gave me permission to use his video back when he posted it -
