Hello everyone. Thanks again for all the help and interest. Ok, today i have spent a few hours sorting the problem. firstly the drum and backplate i am sure are correct for the bike, chain is perfectly aligned, as i said before the wheel is 3/8 of an inch to far to the right the stub axle being too long is the obvious problem. I priced parts today bit pricey, would knock a hole in my disability benefit, so i measured everything while sipping a cup of hot thinking medicine, and then i set about it. First shortened the stub by cutting the end off close to the second flange/ ridge, i then found two thickish washers, drilled them, squared up the end of the stub and welded the washers to the stub in place of the bit i cut off, refitted the stub and wheel, the spacer number 29 of course was missing, but the bit i cut off the stub fits perfectly,after dressing the cut face flat and square, spacer number 30 now fits perfectly, not too tight or slack snug push fit by hand. Wheel is now fully meshed with the drum, wheels aligned, and chain tension done.Just as well keep going, my disability is severe arthritis, total replacement of my right knee three years ago, but it only bends to 65 degrees left knee needs doing badly, but not if it's going to end up same as the right.Now youre wondering how i ride my bike, well i made a footrest out of a pair bantam handle bars and bolted to front engine mounts, shortened gear lever and fitted vertical, remote rod from lever to rocking heel and toe pedal, works well. Cheers all the best Ian.
