I can’t fly RC planes any more due to the lock down, and I’ve got a backlog of unflown planes, so my needle cutter is a bit pointless. Instead I ordered some Rennie router bits that was the only recommendation I could find for bits in the UK, and a 1/8" collet for my old Bosch router, printed a mount from Thingyverse and had a go at wood.
I feel like I’ve finally passed the initiation 
I got a bit confused in Estlcam and instead of five 1mm steps, it dug right in and cut 5mm in one go, but otherwise seemed fine. The edge was fairly neat, even before the finish cut.
There are slight marks on the bottom - is that normal, or does that mean my router is not vertical? Or deflecting as it cuts?
The marks at the top of the picture are where I was impatient waiting for the bits to arrive and experimented with an old countersink bit, just trying to cut a straight line. A 2mm depth of cut wandered all over the place, but a 1mm DOC was at least straight. The line under that was a test with the proper bit.
Now for some signs…
