Hi Julian...I made mine from aluminium and blasted them for a matt finish. Originals were cadmium plated. Stainless would work equally well.
Original handlebars were made from 14 gauge tube which has a wall thickness of .083". So the bore size of an original set of bars (or good quality patterns) should be approx. .584" diameter. I made mine a snug 'sliding fit' and glued them in place with some clear silicone and they've been in place now for a number of years....Ian
I'm fortunate enough to have access to loads of stainless and a Mazak Quickturn Smart turning center with C axis, therefore I'm tempted to knock a few out if anyone would be interested?
Ian, is there any benifit in making these longer, to slide inside and turning them in to bar weights to reduce vibration[/quote]
Stainless or brass would both be ideal medium to for bar weights, just let us know rough lengths or ideal weights to achieve and I can model from that with our Onecnc cad package.
I would be interested as I had to remove my canvas grips after my 2010 ride over & back to France - my hands buzzed like tuning forks when I arrived at Portsmouth docks - cannot be good for you long term
