Did you ever get a reply on this ? If you are a VJMC member you should have seen an article I had published in Tansha last year (?).
Basically very impressed with the results.
Hi Phil you are the only person to answer my question.I did read your article from a member of your club who lent me the mag you made the fitting sound very simple but i am sorry not simple enough for me.i have not long finished a 7 year restoration on the bike I saw one in the 60s and one came up at a bike shop near me and the rest is history.Where are you in the uk .I live in Cambridgeshire.
Thanks Richard
