Need to find somewhere that can lathe down a set of caliper spacers, nothing major just removing the shoulder where it meets the fork.

How do I find a machine shop that can do it? Google brings up lots of industrial engineering companies. What do samll scale engineers call themselves?

I just googled 'machine shop near xyz' and found one that looks like they do one-offs at a reasonable price. Unfortunately not in your area. You could try local historic bike/car groups...chances are they know people who can make things or make things fit.

Normally word of mouth is best bet. Failing that, visit the metal-bashing end of town and ask around. Sorry if that seems a bit flip, but it was how I 'discovered' the various trades I needed. Once you've found a lathe man/engineer, ask them for a recommendation for a welder, or a plater or whatever else you need.

The caveat is that I'm based in Sheffield and it's harder to avoid the various metal bashing trades than it is to find them.

Try Nick Chambers, he's on Facebook

You're looking for a machinist... with a mill or a lathe. We find these miserable buggers in machine shops.

Anyone who's old-boy-in-a-flatcap enough to do what you want ain't gonna have a website. That's your problem really. So it's word of mouth as ya man says! Or randomly mooch about industrial estates?

Even 'small machine shops' are predominantly CNC now, there's not a huge market for manual stuff.

I’m a bit of a lathe person. I just pronounce it differently.

Thank you, I'll get measured up and arrange postage.
Probably should start a thread in the projects section. Who is best for image hosting these days?

That thit.

I use flickr, but only through habit and not because I've looked at other options.

Kieron Sanger In Leicester.
Or the Machine Shop

I use postimages.org. I like it because there are no accounts needed, upload the photo, set the size and it gives a URL.
I wouldn't use it for long term storage but for forums it's good.

Giving this a try

If you can see the image it's the shoulder I need machining off to sit flush against the brake mount.

That's the bit to machine off.
The r6 calipers have a step which fits into the top of the spacer. The original nissin calipers bolt to the fork leg without any insert, just flat to flat. Doesn't seem ideal. It that's how they are.

Had thought about removing a small part of the thread in the fork bottom for the shoulder of the spacer to fit.

Just get the barstard file out and flatten it yourself

Some more helpful images





I'd take a photo of the original nissin setup but its raining and I don't have a garage.
