Park TS-1 truing stand radial hop indicator by cmh

Last crawled date: 3 years, 1 month ago

I like my TS1 truing stand - have had it since the early 90s and have built and trued many, many wheels with it. One thing I don't like is using the indicators to visualize a radial hop, if the wheel has any lateral hop it can be tough to see the radial hop against the curved top of the indicators. To fix this, I've taped a straight edge to the indicators in the past, but that's annoying. I made this super, super simple thing to just drop on top of the indicators and give a nice level reference for spotting radial hops that isn't thrown off by lateral hops. Print it in black if working with a black rim and it'll make any lateral runout very obvious.
It's wickedly simple, but if you see potential for improvement, let me know - or I've attached the original Fusion360 file so you can edit it directly. Just post a remix if you do, I'd love to see it!
Update: Sep 1 2018:
I was printing another to use at work, and realized I had no idea why the first version had a longer bit. I cancelled it while the sides were even, and it works just fine. I changed the model so it's smaller and prints quicker, and still works perfectly.
