This is an introductory video for our new Clark Video Thickness Guide for our hollowing system. It is designed to replace the laser system. Feedback is that it is much easier to use than a laser since you can have a representation of entire cutter shape.
This is the new design for out hollowing bar. Now the standard bar is 30" long to allow hollowing to the same 20-30 inch depth but has basically a handle 18" long to extend the bar to allow a portion to attach the laser onto. The laser can now be easily removed or replaced just by taking the extension on and off for a much more convenient deployment of laser or camera thickness guide device. The extension can also be used as a hollowing bar for external use or small hollowing projects. The extension can be used as a handle for general turning! The 30" hollowing bar can be used for smaller projects. You can order a 24" bar with 12" extension for a mini lathe with 12-14 inch swing.
Bearing alignment in an important process for proper function of the Clark Deep Hollowing System. This has been done for you by us before shipping. It may be something you might have to do in the future so here is our technique.
John Tisdale of Dallas Texas creates unique and large hollow forms from mesquite burls. This is a very challenging task. See him working on perhaps the largest mesquite burl ever hollowed. The 700 pound hunk of gnarly wood has required many special modifications in his shop.
See the basic Clark Hollowing System set up on a 24 inch swing lathe. Dr Clark explains the basic features that make this captured system function and introduces the angle of attach feature.
When cutting too aggressively, it is possible to dig so far into the wood that the lathe either stops or the wood or tooling breaks. With this system, these catches are of little consequence but become infrequent as one learns to use the system. Because the turner has increased mechanical advantage over the hand method, it is easier to overpower the cutter. One must learn to apply the proper amount of force to cut properly.
Our laser depth and thickness guide system articulated and rotates to avoid the arms of a steady rest. Other systems are fixed at 12 o'clock and cannot be adjusted to get out of the way of steady rest arms.
Although there is vibration of the laser holder during hollowing, the alignment is not affected. We have developed an additional stabilizing arm which will be available soon. Our thanks to John Williams of Tampa Florida, one of our new distributors for the idea!
Here John Leggett is demonstrating the Clark Deep Hollowing System using the laser and Fulcrum Support Tube on a 20 inch swing lathe. This happened several years ago at a Virginia turning symposium.
See the use of our system for external hollowing. See how with a missing arm our large hunk of wood flies off the lathe at the first touch of the cutting tool demonstration the need for a steady rest! See the various advantages of this system in action.
Going to 18 inches deep on our project. The basic system is capable of going to 20-24 inches and this experience would be even easier with the Fulcrum Support Tube shown in videos below.
Very deep hollowing beyond 30 inches is possible with the Fulcrum Support Tube. It is named because it proves significant mechanical advantage to the turner and stabilizes the bar to create a smoother hollowing experience. Thanks to John Leggett!

Without a steady rest, one is likely to rip the project off of the lathe during hollowing. Here we forgot to put on one arm and see what happened. With a steady rest, a faceplate is not necessary, in fact, a drive spur could even work.

Created in Solidworks software.

With this attachment, rope twists, barley twists, engraving on a curve etc is possible on your woodturning lathe. We are showing a 3 hp router with stepper motors running the axes and a large servo motor turning the spindle.
