I started on the drilling this arvo. It didn’t go as well as I hoped. The drill bit slipped in the collet so I had to re-wrap it in more alfoil. After doing that I was still on the first couple of holes when it was apparent something was wrong (loose). I finally discovered I hadn’t tightened the nuts on the compound angle yesterday so it was slowly twisting around with pressure on it This caused the drill bit to rub against the part.
Going by the look of the first round of holes I figured I had lots of space so I decided to use a 2mm drill bit for the next round. The 3D model I drew up only had 2mm on the outer circumference of holes. I was tentative at first trying to make sure I had the right positioning. Then on the 3rd full depth hole I made a mistake on the dividing wheel and drilled it out of alignment. I don’t know how many holes I drill before I realised it was it was out

It was pretty tedious work. One more round of drilling to go…
