Bob, Thanks for the information. In fact, I measured the threads' pitch with a set of gauges, which is why it seemed so perplexing. Although you've convinced me that 26 tpi is the intended pitch, the 26tpi gauge certainly did not give a perfect fit. For the short section of axle that can be measured, I'm not certain it fit any better than the 1mm gauge. It was definitely a better fit than the 25tpi, though. Perhaps the problem is that the axle's threads are slightly distorted from being mounted in a frame. The truly unusual measurement is the across-the-flats size of the axle nuts. It appears to be 13.5mm or more likely, 17/32". Is that a Whitworth size? Best regards, Fred Rednor - Arlington, Virginia
