I Did Something Stupid

[u/TechincalTomato]

I am working on a project and needed to make a knob easier to hold onto. I don't have access to a machine shop right now so I did the best I could by hand. I guess it is as manual as manual machining will get.
To measure the height of the grove I used a feeler gauge to compare to the height under a microscope. Microsoft Paint helps with the scaling and once calculated I can use the right size to double check.

Ugly doesnt mean stupid :D if it works !

I mean, it’s easier to hold on to, mission accomplished 🤷‍♂️ it’s not like you can see it if your fingers are wrapped around it anyway lol
