After the inside of the body was done it was time for more grooving around I wanted to have horizontal indents/ grooves on the tailcap and the body. To achieve that, I used my rotary table on the milling machine. To make sure everything was parallel I had to measure the deviation in x and z direction . It was supposed to at most 0.05 millimetres in x/ z direction after 10 centimetres in the y direction. I attached a lever gauge (correct word?) to the pillar of my milling machine and tried to measure:
This was the moment my lever gauge died:
Unfortunately I didnât have time to repair it so I replaced the lever gauge with a dial gauge (again, correct word?):
I started by grooving the tailcap with one slit every 20° resulting in a total of 18 slits:
After having done that I continued with the body. I wanted 12 slits on the body, one every 30°:
Now, this is the point where I messed up :person_facepalming: Forgetting to think, I continued to make two slits with 20° between them. Luckily I noticed my fail after the two first slits, before I could mess up too much, but still - I couldnât do it every 30° degrees like I planned. I also didnât want 18 slits, so I tried to save it by making 14 slits in total, one every 20° and then the next one at 31.43°:
I was really lucky since I actually really like the pattern now, but my fail goes to show that you always have to be 100% focused. Well, after this near heart-attack-experience it was time to calm down with some homemade kebab for dinner:
To finish the body I first parted it off:
Here you see the ânewâ pattern on the body:
And then I put the body right back on the lathe to make an indent for a brass ring, which will carry the switch signal:
And here we go, the body is finally done:
