Tried years ago. Doesn't work. Hit the cue ball near the edge of the tip and a big chunk flys off. If the tip mushrooms, the overhang needs to be trimmed off. You can burnish it then.
I started with an Atlas. I used a steady rest with a bearing in place. Appropriately sized donuts were used for various sizes. Got by 2 years before acquiring a 1236 Jet. Been using it since 1985.
I had bought every new color from 1983 on. First linen purchased was from Hurlbert for $16 a pound. I am under the impression another company produced linen after Blue Mountain.
If it doesn't turn out like you hope, you can rewrap it black. In 55 years I have accumulated over 20 colors from Blue Mountain and Hurlbert. No matter what color you use it is easily changed.
Had that problem one time. Rolled a wet towel around the shaft near the joint. Clamped the shaft in a vice. Two of us turning the butt were able to unscrew it. No damage to the shaft. Good luck!
I do it myself. Unfortunately the motor on my metal lathe is being rebuilt. Out of business for now. There are many capable builders out there. Just ask in your local poolroom. The other cue looks like zebrawood to me.
The Brazilian Rosewood itself is worth more than the cue. Consider having a local builder reconstruct the wood into a beautiful cue. I have converted several of these cues to something special.
