I started cutting a bushing out of aluminum to make the speedo fit the headlight shell, but before I finished it I gave some rough dimensions to a buddy who then printed one out on his 3D printer. The first one is out of cheap material just to see how it works, when I finalize the dimensions he'll make one out of some softer material for me so it has a little give to it.
A little tweak to the inner diameter and a test fit. Don't mind the tach mount on the right, it goes away now since the Acewell is a tach too.
Works like a champ. Except the headlight shell I used as a pattern doesn't match the one on the bike so the fit is a bit off… but that's nothing that can't be fixed in the final version. Good enough for mock up. Now on to working out a way to drive the speedo.
The next day I went downstairs to clean up the shop so it'd be easier to work on things. Got bored instantly. Instead I put a little more time into the aluminum insert.
This headlight shell will likely end up being painted silver. I'll probably just polish this up and use it as.
