Abrasive Coping Set-ups

[Clockwork]

Is there any desire for a Z adjustment?

That set-up looks good. I have access to some aluminum extrusion, so that's similar to what I had in mind, although with a longer belt. How long does that belt last?

I occasionally make a Z adjustment by unbolting the V-block and placing a spacer below it.

Yes, You Can Use A Drill Press

So I've read this thread with interest. Just over a year ago I bought from Rich Powers his abrasive belt miter tool that James Morikawa made. I set it up once on my drill press and tested it out. I have to admit that I wasn't blown away and decided I needed to up it's game and learn it better. Since I had a milling machine sitting that I never incorporated into mitering and my next couple of frames were going to be traditional round, not very thin walled and not hardened steel I figures I'd turn my energy to the mill and a hole saw set up first.

Which I did and am pretty happy with my results. But then this thread comes along and my attention returns to the abrasive miter tool. So all I can show is the link to James' website shots and a little text. Maybe in time I'll get the tool up and running to my liking. Andy.

The ability to whip up any mandrel size needed is pretty cool too. Just made this for T47.

A Litespeed tour was just posted on Bike Rumor with some abrasive mitering pics. Note the very long belts and lack of coolant. I wonder what the belt speed is?

With titanium - how are they cleaning the mitres after the abrasive belt? Won't the belt leave small containments in the mitre which will effect the weld?

This I covered in a post a while ago

In our industry we use acid to remove any impurities, , this is why I doubt there are any problems we regular radiograph each weld be it aerospace motorsport or medical.

I'm sure things in critical industry such as ours way surpass a bicycle yet it is common practice, there was much development and analysis put into how we make tubular structures and this method was valid
