14mm is the max tip size allowed in Pool tournaments. The shaft can be thicker like the way that the snooker shafts taper in the first 2 inches or so down to 10mm or smaller in diameter with a brass ferrule.

It does have a tail stock, just that the unit is rotated 180 deg to give more room for the working of the tip. Very clever indeed. The tailstock looks to be travelled just like a carriage is done with a hand wheel. Very interesting. Thanks for posting.

You can do what a lot of snooker cues do and taper the very front of the cue. In your case, you can just taper the ferrule and then put on the 12.75mm tip. Even though it is 5 thou per side of taper it will be very noticeable to look at. If you don't like it at 12.75mm, just put another ferrule...

Thats very interesting. Can you please post a picture of the tubes as you receive them, with a reasonably close up pic.?

Cutting it wet stops free dust in the shop. You want a system so that you have no free dust or fine pieces around. Its a type of material that you just can not be too clean.

If you reduce to the diameter to being a close slide fit, it will not reduce the integrity of the pin at all. If you make the front too small in diameter, it may as well not be there as it will not have any support. Most threads, are supported by the vee formation or the effective thread pitch...

Lenses can be removed and replaced by competent surgeons. They also do cornea replacement surgery and much much more. It is truly amazing what can be done for eyes these days, and it's developing rather rapidly as well. New techniques, new products and better ways to scan and measure the eye to...

You can do it without a lathe too. Just makes it slower to get there.

I use a paper towel, and put a little oil on the folded paper piece. The I add a few drops on the towel and hold it against a dummy piece, moving it a little. This primes and seals my paper towel. Then just like Sheldon does, drop the ca on the top of the shaft and hold the towel near the bottom...

Have a look through my album, and see if it is there.

There is now nano technology cnc machines that can mill to a mirror finish, or turn using frequencies and technologies to counteract the vibration frequencies of the part being turned. They are now so accurate, that the material itself is not capable of maintaining the geometry that was cut into...

It's where the item is ground with either e wheel or a belt, and is supported with a drive and either a blade or wheel that helps support the part or piece being ground. Search for centreless grinding. Its interesting stuff.

If you like the cue a particular maker is making, the tools they use to make the cue should be irrelevant.

there is no way to blend that and not see it or keep the same exact look on the cue. You can use wet dry paper with water and a little drop of detergent as a surface tension breaker, and draw polish the immediate area with 800 grit paper initially. You may need to start with 600 or even 400...

If they really had OCD, they would be calling it CDO, as the acronym should be in alphabetical order.

We have a place in NZ that makes only carbide tooling, like specific sized non standard reamers (Ø6.05mm) as an example, special diameter milling cutters, even carbide taps. But does not make dies though or ring gauges. A 1 off item is around $200, but a set of reamers that are -0.02mm and...

Dave, making little dams with modelling clay works if you want to use a epoxy resin or slow setting Ca. Just need to keep it about 1mm away from the edges so that any oils do not creep to the area being worked on. Have made dams out of plaster of paris before and that does work well, but takes...

Well done Dave. I would use some carbon micro fibre as a filler or sand some carbon tube and use that. There is also milled or chopped carbon fibre. It's unidirectional carbon that is cut to about 1/6 inch, 1/8inch(Most common) and 1/4 inch long. you can carefully place some 1/6 in the bottom...

I don't know where you get the idea that it is always straight and stable and does not ding.

It depends on the way the shaft is manufactured, as to if it is sanded, or centreless ground like fishing rods are. Some weaving machines can produce product that does not require sanding or grinding.
