chips are chips, congrats!
Here's my latest odyssey - what with a new job, a mountain of pears and grapes to process and not very efficient machines, this has taken me a while.
Aim of the project was to make a robust clamp for my commuter bike to mount the front mudguard to. Not that I've needed it much in Walla Walla so far, but I guess it'll rain at some point over the next year. You might be wondering why I need to make such a clamp, well that's because it has a front suspension fork that doesn't have any way of mounting stuff to it at the top and I can't drill a hole through it as that'll make a bit hole in the air spring
The original half baked effort that sort of worked
the new split clamp, with three IDs to fit the bottom of the slider. Damn Cannondale didn't make it round either, so the smallest ID is elliptical of sorts (25 thou each way off center in the 4 jaw for the bolt sides).
The undrilled flat is just in case I get a dynamo light at some point.
Now the bit that the mudguard will clamp to
Trying out slotting which was an interesting learning experience. Somewhat scary running a 1/8 endmill in the drill press/ mill at ~3000rpm, but it cut relatively nicely.
All together
and on the bike
I have another small bracket to make (much simpler) and then I'll try my hand at anodising them all before I put them on the bike.
