If I had 10 (or fewer) boomboxes, I would ask Trommelmops to RE-KNOB every one of them. However, with the number that I have, where do I start? Better to just leave them be since after installing new knobs, I can't imagine ever selling the boomboxes since they would then have such high sentimental value that they can't ever be sold.... I would have to be buried with them I think!

Oh i must laughin
Here is the next level of the knob: I have made today a further tunerknob to see whats possible.
I build a new tool to hold it, then i milled in the jacket surface some cool looking grooves with 2mm cutter.......

are you milling with the old school bridgeport type manual machine
or is it all computer driven ?

but the Trommelmops use the old school or better real handwork machines. CNC is to coslty.....make first a drawing...then compile it to a g-code.....and then you can mill or turn.....the time you need to make the data you need is to much. Im able to mill and turn very good by hand and need less time thanwith cnc based........
My experience told me this. Only when you mill with cnc very complicated designs and shapes. Then you should use the modern method i think.

So dear members and followers 
, today the Trommelmops has tested some inserts,
I can say that it is sucessfull tested for the d-shape knobs. It is tested on a 6.00mm d-shape shaft. And i can say it works fine.
When i put the insert to the shaft, you can turn the shaft, without that the insert slips. It depend on the steelring i made.
In the inserts are no bumps. Its in original only for the line up or for the right positioning. Its absolut not needed. Maybee i chande the design.
In original they have sometimes only one cut. So i test this also. I will figure it out what the best is.
I have made the cut with a 0.3mm thin bladecutter. But before i must made a special holder for the bladecutter....Like always
The material for the inserts i took is the right choice.
So from now on i know how it goes

Dear members and followers.....
here some news from my workshop: first the pom inserts......
With a special made tool i made for my lathe i cut the steelrings with a 0.6mm thin VHM Bladecutter from the tube.
After that i cut the steelrings and pressed the inserts with my press in the shells......

The more I see these (and his other knobs), the more I want a set. Or two. Or three.... Heck, how many M90's do I have anyhow or should I buy some just so I have an excuse to buy some knobs, and what other models does he make knobs for?

That's exactly how I feel, but my pockets are not as endless as the knob selection we could have him whip up!
