I have seen the Ball Techs advertised before.
If I didn't have a lathe or 3, this is one that I would try fer sure.
When someone said, "Damn trimmer", it made me think of the more expensive Porper.
Because I said the same thing, (much worse actually), many times before I sold it.
There are a ton of small inexpensive tools out there that can make the job a snap.
Don't have to spend a small fortune on Doo Dads like I did before I saw the Light.
Spend a fifty on the small tools and save the rest for good tips, glue and sand paper.
A recent thread on tipping by a player from Norway, or one of those countries that had Vikings at one time. can't remember.
I think his AZ name is Kim Bye or something like that.
He purchased one of those Japanese Chisels and a Japanese knife like the guy in the UTube video.
His first tip job was great using just those 2 items. And that is basically all one needs. Some glue, sand paper, and of course a good tip shaper. I prefer to use a curved shaper that holds strips of sand paper.
