Just completed the new rear mudguard and stays on my TT Rep.
However, the original tubular lifting handle has a few cracks in it and I will have it welded if I cannot locate a replacement item.
Does anyone have a spare handle that would be prepared to sell (either original or copy will do).
nobody knows the answer for sure,
where the millions of nuts go,
that fall on the floor.
he handle has now been welded and is nice and strong. A bit of cleaning up and repainting and it will be fitted.
I wanted a nut welded to the inside of the rear brake adjuster nut (on the end of the brake rod), which had the threads stripped. However, the nut will simply not accept welding (obviously some strange material), so does anyone know where I can get a replacement?
It should be possible to get a Helicoil insert fitted to replace the worn thread, but I would suggest fitting a locknut too, as a belt-and-braces safety measure. Have you tried sif-bronze welding ? That may work… I have come across brass cone adjusters and ferrous ones too, so check it out with a magnet.
With a view inserting a helicoil as suggested by Brian I measured the brake rod and adjustment nut and it appears that mine are slightly different.
The rod appears to be 9/32″ and the nut 5/16″ (both have 26 tpi threads). Consequently, the nut, although slightly catching on the rod threads, slips.
The nut appears to be of original Scott design ; perhaps the rod was replaced at some stage – although all the other bits screw on tightly.
Does anyone know what size the nut should be?
On vintage Flyers, TT Reps, etc., the brake rod and fittings should be 5/16″ BSCY 26tpi. On safety-critical items it is best to think that in the past 85-90 years the rod will have been bent, corroded, and perhaps replaced in an inferior material. Best practice is to renew the rod from a length of EN8 or similar steel, and have a very close look at clevises, split pins, etc.. Right-hand brake pedal bikes should in theory have a slot/groove in the edge of the gearbox tray to stop the brake rod rubbing on the tray. They can also rub on the underside of the gearbox, leaving a groove that occasionally wears into hole in the shell ! I’ve just repaired one !
