All my stuff here...

Groovy Cycleworks 330-988-0537: Martins 15mm thru axle ti fork...

FWIW, mitering/coping unicrown blades is so much easier on a horizontal mill, had a vertical set up for years with a standing tee-pee fixture, worked but it was less than ideal.

I've also upgraded the bender with a power unit and internal madrel that allows .035 to be bent consistently.

I misread that as UNICORN ...............then i thought about it

Steve,

I assume you are asking because you are looking at changing up your process?

What are you currently using and what are the shortcomings you hope to improve upon?

Well, I was hoping to see some ideas on mitering with a vertical mill, as I just don't have the room for anything else in the shop - lathe, horizontal, nothing - I'm wracking my brain trying to figure out a new floor plan to fit more, but I need extra room to turn around, stuff like that......

Of course I could hand miter them, sure.
I really like the look of a straight blade unicrown, and was hunting for ideas, that's all.

Here you go Steve. Recently finished this one up. Very solid. One thing I do though is I tack the two tips of the fork legs (top and bottom) before mitering. I have a set of 100mm modified Anvil dummy axles that have the same center relief as Don's 135mm dummy so everything is interchangeable. Not to mention a tad bit more rigid. Dummy axle then can follow the assembly through to the fork fixture.
