Quote:Thanks for the post.Question: What's the best blade TPI to use for sonotube and is there a way to avoid jagged edges when using this method on a sonotube? I've always been unhappy with how rough the edges are when I cut sonotube.
Sounds exactly like a metal polish I used to use on my 650 Triumph engine/transmission case covers- Simichrome...
Hmm... biker many moons ago... me, too- in the late '60's. Had a 67 Triumph 650 Bonneville TT Special, and a '69 Kawasake 3 cyl triple... amongst others! Wish I still had those two bikes... *sigh*
