In order for the cable fixings to attach and bed into the frame properly I decided to carve out little trenches for them to sit in. I think it will look much nicer with them sitting flush with the wood and I also think that the strength of the bond will be much better.
I tried hand carving with a chisels on a test piece of ply. It was fine when on the flat surface but carvin end on was a bit of a mess. I think my small chisel needs sharpening.... again. Anyway I found that my router has a blade that is a perfect fit and on the placements along the frame where there it is flat or convex I can rout out a good shape. The ones on the complex curves will have to be hand carved, once I have sharpened the chisel.

The other thing I have tackled recently is the seat post hole. On the Mk1 I really made a hash of the seat post, it was all on the wonk. Essentially because I rushed it. So this time I carefully set up my workbench and braced and clamped the frame making sure it was plum square with my small pillar drill rig. After lots of fiddling and checking I was ready.
I used a orger bit in a standard drill to get started. The bit worked a treat and once I got to the limit of the small pillar drill action I did the rest carefully by hand. I orger bit works best at a sower speed and with the straight hole established it didnt deviate as it is such a strong drill bit.
It got quite hot and I had to take it slowly, constantly clearing the chaff and letting the bit cool down.

I would still like to have an adjustable seat but I am trying to figure out the best way to fasten it. At least I know it is straight this time and I can permanently fix it in if need be.
