I have a friend who owns an Engineering firm and has come up with a way to use a 20mm hub (or probably a 15mm come to that) - so i'm going to have a couple produced for my own use and initially to try/test.
If it works perfectly (which i'm 99.9% sure it will) would anyone be interested?
- no idea on cost yet, as it will depend on time/numbers and material used, but looking for an idea to cost it.
