It's all turning and best wood hollowing tools videos sharpening with carbide tipped woodturning tools! Pat HarrisJan 26, Still going to look into a hollowing system - always seem to be looking for something to make life easier. Hugh and Dale, I had heard of the Gizmo hollowing systme last year but didn't remember the name or company.

Gone forever is the long learning curve where precise angles and special tool presentation techniques must be mastered. Also gone is the need to master many sharpening techniques before you can even begin to turn, not to mention the expense of all that sharpening equipment. You can focus on your project and not on techniques or sharpening. No long learning curve or expensive sharpening equipment. You can begin turning as soon as your box arrives because each tool comes with a very sharp, rotatable carbide cutter.

Some modifications are minor, while others are major. I am very thankful for feedback received from many wood-turners over the past 10 years or so which has helped me refine the Clark Deep Hollowing System. Overall, the original design has proven to be excellent! However, the original cam-follower bearing design and slot in the hollowing bar suffered from binding. The second generation present adjustable ball-bearing and better machined slot provide smoother operation without binding - a very significant upgrade in performance.

The Fulcrum Support Tube and a new way of connecting the Swivel Pivot Apparatus have proven to be significant advances! Recently, I have been blessed to work with Jon Leggett. He has challenged me to extend the system's performance envelope. Together we are defining hollowing depth capabilities and providing specific recommendations for cutting tools, accessories and techniques for various depth ranges.

There are other hollowing systems on the market that cannot hollow well beyond the 8 inch depth range. I know this because I get calls from turners who are not satisfied with other systems they have purchased. The standard Clark Deep Hollowing System can easily hollow to inches and to about 22 inches with a very careful and slow technique. Some of the variables influencing results include; type of wood, type of cutter, angle of approach of the cutter, position of the cutter relative to center-line and features of the hollowing bar itself.

Of course, a major factor affecting depth capability of all hollowing systems is flexing of the bar. During deep hollowing, the tool tip is suspended a long distance from the tool rest. Tremendous forces are generated which can lead to unsavory vibrations. Vibration can be minimized by larger diameter bars, less aggressive cutting tips or very slow removal of wood. Larger bars are cumbersome and slow removal of wood is no fun!

With new accessories the Clark Deep Hollowing System is potentially capable of aggressive, relatively rapid hollowing up to and possibly beyond the 30 inch depth range with the new Fulcrum Support Tube. The Clark Steady Rests are an integral accessory for hollowing. Forces exerted by the hollowing system are tremendous. The wood can be much more easily torn from a faceplate or chuck without a steady rest. Any wood-turning task can potentially be dangerous!

Proper protection, instruction and experience are necessary. Beyond that depth can get tricky and will be easier with less aggressive cutters. New turners will certainly appreciate the smaller cutters and especially guarded cutters. Hollowing can be difficult, and there is definitely a learning curve. Consistent practice and experimentation with variables being discussed will certainly be fruitful.

Any cutter will work well to the limits of the wood and the cutter itself. Between 15 to 23 inches deep is better controlled with a less aggressive cutter and delicate technique. The 19mm round carbide cutter I sell is shown on videos at www. Some have suggested that this cutter will not work well because it is too large. Our experience has been excellent - it removes wood quickly and has great longevity.

Yes, it can be aggressive if too much force is used. He did not even have to rotate the cutter to an unused edge. However, rpm has to be slower than expected, and the cutter is very sensitive to angle and position relative to center-line. When Jon and I were demonstrating at the Virginia Wood-turning You Turn 2 Symposium in September, we were hollowing an 8 inch diameter hardwood log at about 18 inches deep with the 19mm cutter.

I turned on the lathe and set rpm. Jon began hollowing and experienced bad vibrations to the point that he could not hollow. We incorrectly thought the vessel has warped overnight or that the log had moved in the chuck. I was very surprised that problems were solved with an adjustment down to rpm!

The cutter must be set at center-line. During removal of wood at the bottom, the angle of the cutter should be slightly down about 10 degrees from horizontal.

Side removal works better with a wider angle from horizontal. The most difficult area to hollow is at the junction of the side and bottom when very deep. Removing the nub right at the center is easy if the tip is at centerline and angle is closer to horizontal. Here is the really tricky issue; using a 1. Turners typically use very large diameter bars to get to this depth and beyond, but the bars are heavy and can be difficult to control.

Jon Leggett has used this system to hollow to 30 inches with the standard bar and an 8 inch Fulcrum Support Tube Accessory.

This Best Wood Hollowing Tools 02 accessory mounts on the tool rest provided with my system and greatly stabilizes the bar. Extreme depth hollowing produces vibrations in the bar due to flexing of all the components from the base to the cross bar and the hollowing bar itself. With a secondary banjo under the Fulcrum Support Tube Best Carbide Woodturning Tools Quad there is even more stability.

Any turner desiring to frequently hollow beyond 15 inches consider a 12 inch Fulcrum Support Tube. Those looking to hollow beyond 15 inches may like a longer Fulcrum Support Tube. Some lathes with a tall banjo, such as Oneway lathes, will need a shorter secondary banjo to use the Fulcrum Support Tube.

It was a wonderful suggestion! The screw holding the pillars together must be tight. If play develops then there will be a source of vibration which will limit depth of hollowing. With the joint lubricated with grease, the screw can be much tighter. The pillars turn much easier and there is no binding.

The blowup in the lower right corner shows the round cutter. These can be ordered straight or curved holders. These are made in Switzerland of high tech carbide and never need sharpening.

I believe they actually cut rather than scrape the wood away. Cutters and Holders. It is useful for more than just deep hollowing. It can be set up to do external turning with an extra base.
