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.

New Video Thickness Guide
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.

New Segmented Hollowing Bar
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.

Adjusting the Bearing on the Clark Deep Hollowing System
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.

Deep hollowing a large mesquite burl with the Clark Deep Hollowing System and Steady Rest
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.

Catches become uneventful with the Clark Deep Hollowing System
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.

Setting up the laser depth guide for the Clark Deep Hollowing System
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.
Play Video
Notice how the adjustment of the laser is constant even after much hollowing.
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!

Deeper Hollowing with the Clark Deep Hollowing System including the laser.
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.
Play Video
The following 4 videos show the Fulcrum Support Tube
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!

The Clark system works very well. Today I finally set mine up and hollowed a small vase about 13 inches deep. Because of the laser and the super high quality steady rest this is the thinnest vase I have ever made!

This is a super hollowing system. If you want the very best experience hollowing then this is the only system. Keith has engineered and produced a system that when used properly is nearly vibration free. When you plan on spending the day or week hollowing, you may as well enjoy it!
