I've come a long way with Mk4.
The plan was to do something similar to
Mk3 and to not only include small improvements, but to use hemp bast fibre for aesthetic reasons. I have used some carbon tow underneath.
Here is the current look after the final lug was laid up and I have stripped off the tape and protective covering.
There is a LOT more work to do sanding and shaping the lugs, then I move on to the fixing of the various mounts and guides. The lugs will look good with a clear coat on them, but don't look great at the moment.
Not everything has been easy or worked properly:
- the hemp really doesn't wet out well. It's a real PITA to compress.
- I've had to do some touch up patches on the head tube and seat tube lugs to fill gaps (and I'll have to some on the bottom bracket too)
- the way that I tried to incorporate the FD cable path doesn't seem to be working well. There is a lot more work to do there.
Frame is noticeably heavier than Mk3, but I'll wait until I've sanded some more off these lugs before I throw it on the scales.
