Original (now lost) clamp:

Option 1

It looks fitting, despite the opposite being true.

option 3 - bored out 600 ano grey

this!

With the slot in the band I think that the lathe would just chew it up rather than boring it out.

If the band was solid then no problems, but using the TIG to en-solidate it before boring, then cutting the slot back in would FUBAR the anno finish that we are trying to preserve.

Screw it shut with a shim to simulate clamping distance?

The black is now growing on me.

Clamping and centring it will be a nightmare to start with, even with a four jaw, and the lips left from the edges and hinge will almost definitely get caught on the tungstun carbide tooling tip leading to:

a. Piece coming out of lathe at high speed and ripping someones head off.
b. Snapping carbide tip, which launches into someones eye.

Both these options will result in FUBAR'ed clamp, which isn't really the name of the game. TIG'ing it shut could work, but would fuck the finish of the clamp. Also, let's not forget what happened the last time we lathe'd something for Neil, poor old @moth lost his head, not even metaphorically.

use a cnc milling machine, obvs, a lathe is laughable - clamp the workpiece, orbital motion with small high speed head

do you guys mak byk evn?!

Just use whichever clamp fits, no-one is going to notice either way.

10 out of 10 y'all for suggestions that needlessly over complicate things.

Not really, black is much better to my taste but true, you could achieve this with just never wash it.

Tungsten carbide drills?! What the bloody hell's tungsten carbide drills?! ;-)

Black looks best imvho

Where can I purchase a slim, keyed lock washer?

Sick rizers

Sick risers!! Haha!

What size is that? Obvs it's proper race geo but that HT looks smallish.

57cm top tube

It's the pump...

It looks a bit cack built up.

I'll just keep it as a frame then.

Lovely Frame and nice build. Looking forward to see more ;)

Good god man! Not only does the cat get a fookin huge scratchin post, it's got it's own shelf on the bookcase.
Nice seeing the bikes nearly done, looking good.
