I have made many drawings of individual components of M20 parts.
I'd be happy to share them with anyone else on the Forum.
I'd also like to connect with others who have some engineering skill, and create a body of knowledge we can post here for the betterment of all M20 owners. The Matchless guys to this, so how about us?
Also, I have made drawings of many of the special fasteners where I could get an original. Any help here would be great too.
Robb,
I too have recorded many dimensions of BSA parts.
As for posting, I suggest your drawings etc are more suited to the technical section, where some already exist, send to Henk and he will insert.
Probably best to group the drawings and descriptions, as I have done with all the small parts of the gearbox.
There is a lot of good info buried in old forum posts, but it can be tedious to find.
