I did some nice knurling today
I did some tiny knurling too
The bigger knurling was a modification to the seat post on the folding e-bike. It's Chrome surface was just too smooth and slippery and when I would hit bumps it would slide down into the frame. Hopefully this will help.

The smaller knurling was also for a bike. It's part of my solution for connecting my Sturmey Archer hub to a shifter cable since i somehow lost that connector.

Welding something this tiny without melting it was hard.

This bicycle part is done. Lots of tiny, fiddly welding.

It's not as pretty as the commercial version, but hopefully it will work just as well

I had to redo two of the welds, but now it works and the bike has three working speeds
@MLE_online the knurling is really nice
@MLE_online It looks like a small flail... What is it's intended purpose?
@osunderdog It connects a Sturmey Archer three-speed hub to the shifter cable
@MLE_online great job, but disagree. your version is much prettier 😍
@misternineham aww, thank you. You're very kind (and you also have impeccable taste)
