Handlebar risers/clamps.

[MWF FEED]

I decided on flat, drag bars on risers for the bike, so bought a set of drag bars and looked around for some risers. Couldn't find any I liked, so I made my own. I started off with two slabs of 25mm aluminium, chucked them in the four jaw and turned them to the shape I wanted, then turned them around and drilled and tapped for 10mm mounting bolts. I then drilled a 7/8" hole for the bars, drilled and tapped 8mm holes either side for clamping bolts, then mounted them on a vertical slide on the lathe, mounted a .8mm slit saw in the chuck and cut through to remove the caps. Last couple of jobs were to counter bore the caps a little for stainless Allen head clamping bolts and spin up four 3mm thick aluminium mounting washers.
