Frequently Asked Questions


Q. What is reverse hollow turning?
A. Reverse hollowing is the process of hollow turning a form with a clockwise rotation of the lathe rather than the more typicAL counter clockwise rotation used for most turning techniques
Q. Why would anyone wish to use a backwards rotation.
A. The most important reason is ergonomic. When reverse rotation is employed the tools orient themselves in a position that is akin to the tools used to turn on the outside of the form. The handle will be directed toward the turner rather than away from him across the bed ways.
Q. My lathe does not have reverse rotation. will the lightning hollower work on my machine.
A. Yes, the tool can be set up easily for either rotation scheme.
Q. How large of a form can I hollow with the rig?
A. The rig will hollow a form that is 9" in diameter and 9" deep
Q. How is the tool bit held into the boring bar?
A. The tool bit is held into a square broached hole with supper glue.
Q. How do I change the bit ?
A. Heat up the tool bit with a propane torch until the glue softens. pull out the bit and let the bar cool. replace the new bit and apply glue by letting it wick in like a solder joint. It is best to let the glue set without accellerator
Q. Why isn't it an allan head grub screw used?
A. Two reasons. First is maintaince. Moisture and fine dust can pack and erode the threads of the screw making it imposible to remove. Second is the fact the screw does not hold the bit as succurely as the glue.
Q. I have two Lathes. Can the tool be adapted to either one?
A. Absolutely, simply obtain the proper size tool post and swap it out and your ready to use your other machine.
Q. How come the tool bar doesn't bind up with the torque of the cut?
A. This may be the only time when vibration is a wood turners friend. The cycle of vibration loads and unloads the bar. while the bar is unloaded it moves freely. This happens so fast that it feels as if it were on ball bearings.
Q. What is the proper height for the torque gate?
A. The proper height of the gate places the cutting edge of the tool bit at center or slightly higher"
