Utopia kindly agreed to make some washers for me so I can banish more corroding metal with less corruptible Titanium.

Fitted them today while doing a couple of other jobs on the bike, they fit perfectly, and I couldn't be happier!

They stop the front mudguard getting crushed by the mounting bolts:

Nice one Andy and Utopia for his turning services. I need a lathe myself really.

That's the one Slob, good bolts and the have a nicer head shape than the probolt domed offering. I even found some with the correct unthreaded shank for my hugger.

They normally arrive from Taiwan in under two weeks.

I got some very nice Ti bolts from www.projectcomponents.co.uk If you contact them they can make anything you need, I believe.

It's a local firm who specialise in bike parts.

They are very nice Utopia, top marks.

Thanks for the comments, everyone.
Actually, now that I see them in close up photo, I'm rather wishing I'd taken the trouble to polish them, but at the time it seemed a bit over the top for such insignificant parts.
Sorry, Oz, I should've gone the extra mile really....after all its your monster, so nothing is too good really, eh ?
At some time, if you want to swap them back for the old ones, I'll polish them up if you like.

My conclusions on the machining of titanium....
Low speed, heavy feed....as expected....and plenty of lube/coolant.
Sharp tools are absolutely essential, but super hard carbide is not so important as long as you're prepared to resharpen the tool frequently....which isn't too much of a problem for one-offs and small batches.
This latter point was a valuable lesson learned, as I've never machined titanium before.

Thus inspired, and equipped with the leftover barstock that Oz sent me, and his super-sharp, cobalt drills, I decided to attempt to make a titanium clevis for the rear brake master cylinder, to go with the titanium pushrod that Capo had given me.
It came out really well. I'll post pics when I have them.
I reckon that's saved at least five grams. ;)

The nice thing about this job is that not only did Oz get some bits that are probably not available commercially, but also I learned a lot from the exercise, such that I'm now encouraged to attempt a few more ambitious projects in titanium.

Meh, never trust a company that doesn't list the M600! :nash:
