Hello friends,
I have been reading and learning for years from you all, but I have rarely had anything to contribute. Windy’s very nice head-steady is an exception.
I made something similar last year from a 2.5x3 block of aluminum drilled 1.5 dia and then sawed in half, and a piece of 3/8 aluminum angle. I bought two rod-end bearings from WW Granger, drilled and tapped the block 3/4-10 and put it all together. The job can be done with a drill press, hacksaw, files, and patience. Measure and make a sketch first. It took some fiddling to get it to fit under my steel roadster tank, but it was all worthwhile. It looks pretty nice too.
I figured a frame tube fix that clamped the tube rather than using the existing taped holes would be stronger, and transmit fewer stresses to a fairly flimsy part of the frame.
I have had my ‘71 Roadster for 22 years, and this was the best modification ever--better even than fixing the swingarm pivot with welded nuts, allen head set screws and jam nuts. Also better than e-ignition or sleeved carbs.
Along with a fixed swing arm and vernier isos, the machine now handles as well as any English bike I have ever ridden. The head steady was transformative. You end up with a Commando that begs to be flicked around corners. It vibrates a bit more at low revs, and it squirrels around a lot more in rain grooves, but this is a small price to pay.
Cheers and thanks for the help!
