thread chasing question?

[neil mackay]

I see just recently that there have been a couple of threads on chasing threads etc.

Which brings me to a question. What would be the favourite TPI/s or pitch/s of the thread chasers used by those who regularly make screw threads?

My current in 10 threads per inch...the only one I own....

Neil, great question. I'm curious to read other answers. I took a Mike Mahoney class about a year ago where he taught thread chasing. If memory serves, I believe he taught with 16 TPI tools because it was a nice middle of the road thread count for learning. After the class, I purchased my one and only set of thread chasing tools, and I went with 20 TPI because that's what the Craft Supplies website said was the most commonly used.

I use 1/2" - 8 tpi. for wood.

I'd think that it would depend on the application. In the cue work I've done, I liked to keep it under 18 tpi. Anything finer seemed like the threads were too small to have much strength, and were more prone to breaking or crumbling.

Neil,
I spoke with Anthony Harris this morning (he's a professional turner known for his threaded boxes - http://acmewoodturning.com/). I asked him what TPI he used most often, and his response was 16. Since I only have 20 TPI today, I may be on my way to purchasing another set of threading tools.
