Here’s few shots of sweet wheelset built earlier this month. This theme of black hubs, black rims, silver spokes and silver nipples is a new trend. Historically I haven’t see a lot of it but lately it’s more popular.
I’ve been developing my truing stand for quite a while now. The software has been stable for more than a year but recent changes make it the tool I really wanted. After a few hardware revisions, that part is working well too. For a peek at both check out the video below.
I’m turning my mind to how a system like this should be packaged. Below the video is a survey to get a handle on the demand for a digital truing system. If you can, please contribute! All questions are optional and the survey can be submitted anonymously if you prefer.
(For communication purposes the “wheels” in the screencast part of the video are simulations. I have a simulation driver for testing the user interface, which lets me try wheels far worse than I encounter in the workshop. No wheels were harmed in the design of this system.)
I have a prebuild ritual that involves quite a lot of inspection. I don’t want to call it a checklist — I look over everything deliberately and see if anything stands out. Pay attention to the rim stickers and hub branding so their orientations can be chosen deliberately.
On alloy rims I like to visit every spoke hole with a chamfer tool or a handheld drill bit. This puts a subtle profile in the hole where the head of the nipple rests. Sometimes there can be a coil of drilling chaff attached to a spoke hole — a chamfering pass breaks them off and smooths any burrs. When I visit the joint I look at the internal sleeve, if any. Does it interfere with nipple fit?
Measuring is inspecting
Measuring your own ERD can indicate a lot. Use the measuring step to test fit washers if using them. Do the washers sit nicely in the rim? Measuring will tell you if your rim is round or oval. All else being equal the rounder the rim, the better the expected result in terms of alignment and tension balance. If your rim is oval, take a deep breath and expect to spend a little longer at the bench if chasing perfection. Have you ever found a job difficult and doubted your skills? It could be the rim.
