I have a skewer that is missing an e-ring on its quick release lever. I have replacement rings but have not had any luck slipping one on; they mostly fly across the shop and are never seen again. At my age, such fine work is much harder than when I was younger. Usually e-rings are pushed on from the side but the groove on the lever does not clear the recess. I have had no luck at all in pushing one in from the top. Looking at other skewers, the e-ring does not seem to fit inside the recess and the ring is flexed into place. Any Suggestions?
Thanks Jim

How about pushing it over the point of a pencil to a diameter slightly larger than the shaft on the lever, cut off the pencil tip, and slide the ring onto the shaft. Or something along those lines. I'm on this wavelength because I today have been cutting off turned wooden posts using a hose clamp as a guide to keep the cut level. Not exactly the same problem but some parts look the same.

Brian Good suggestion, Brian. That’s how I would do it. Back in the ‘60s at the old bike shop, I would do things like that but only if I couldn’t get into the drawer where our business machine repair guy kept his stock of handmade tools for this and many other tasks. The guy was a mechanical genius with infinite patience who would spend an hour fixturing a tiny irreplaceable steel typewriter or adding machine part to braze it back together. Gene was also the one who taught me how to braze and got me started thinking how to repurpose old tools for bike repair use. Best, John “wheelson” |

Gene was also the one who taught me how to braze and got me started thinking how to repurpose old tools for bike repair use. Best, John “wheelson” I like hearing about guys like Gene. I remember a discussion in the early 80's about the tool and die makers at WW2 defense contractors and other large industrial outfits. The guy I was talking bemoaned that we were losing them to Japanese manufacturing and called them a national treasure. It wasn't "treasure" but some other word somewhere between resource and treasure.
My best friend (also Brian) from high school became a machinist and eventually a tool and die maker for Dennison Manufacturing, an old local company that made all types of specialty paper boxes, tags, labels, etc. Much of the machinery dated from the 19th century and had been in continuous use since. When a machine broke down Brian had to make a new part. He had all of the original machine drawings but over time most of the parts had morphed into something else. For example, a small actuator tapping away for 100 years comes to resemble a spoon. The situation would evolve as the machine was constantly adjusted to overcome these changes. So Brian's job was not to make the original part, but to figure out a small set of compensating parts that could fix the current problem without disrupting the rest of the existing machine.
He ended his career do micromachining, where you run a lathe that you observe through a microscope.

Jim, I have enough eye problems (bad luck) and a poorly lit workspace (laziness and cheapness) that I try to do jobs like this in a clear plastic box. That's doubly true for anything spring loaded. It's amazing to see what I find on the rare occasions when I sweep the floor.
Can you believe how high and far a ball bearing can bounce, especially odd sizes that you don't have?

I too do some small work in a large plastic box. Sometimes I can place a box beneath larger work. This helps, as in my old age I am more likely to drop things. When I run a magnetic sweeper over the floor I find some long lost small items; other items seem to pass from existence. As for these little clips, they are very small, spring loaded and fiddly.
Ride Happy

No matter how hard I depress the cap onto the lever, the groove in the lever remains below the edge of the recess. I think a ring clip will work better. Ordered some today. The shaft is tapered and the recess and shaft diameters seem to match a 4mm ring clip. I am making a tool for the job; hope it works.
Cheers
Jim
