Default Longworth chucks - cutting today vs. a year ago

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!

Great video David.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Great video. This is a perfect example of constantly learning and using that knowledge to your benefit. You keep changing your toolpaths, not only to cut faster but to save time in the hands-on finishing processes. Now it is time to develop new products for the woodturners. Maybe a few different size donut chucks.

Thanks, Mike and all! I actually have a new chuck prototype here and it was developed by an older gentleman who wants me to cut one for him. Right now I'm evaluating his design, what it will take to produce them at a reasonable cost, and then to see if there's a market. That may be a bit backward but since I'm cutting one for him anyway then that's the order in which I'll tackle this project.

I'll bet it won't take as long as it did for me to make a doughnut chuck.
