Making a template to mitre Seat Stays

Making a template to mitre Seat Stays

I wish there was a clever software program to produce mitre templates for complex seat stay mitres. However it only recently occurred to me to reduce the time it takes to shape two by transferring the mitre from the first hand carved one to the second side. I like to do my seat stays in the “fast back” style for preference instead of using top eyes. With very narrow stays it is fairly easy to shape the mitre to the back of the seat tube, but so often the seat stays are 15mm or more in diameter and require quite a lot of shaping to wrap around the back and sides of the seat tube. It never ceases to amaze me how at first it looks like the tubes will never mate, then with perseverance they all at once seem to drop into place. It does however take a lot of patience to avoid over filing the mitres whilst continually offering up the seat stay to the seat tube.

Custom Frame Builders Association and Public Liability Insurance

Custom Frame Builders Association and Public Liability Insurance

Several informal meetings have taken place between Custom Frame Builders across the UK with a view to establishing an Association. At present there is no formal organisation established but an intention exists to make it such, primarily as a talking shop for exchange of information. Additionally it has been proposed to offer a EN/ISO test of frame integrity in conjunction with Reynolds. It has been mooted it may cost around £300 for 631 tube set and test and the frame can be lugged or fillet brazed or maybe Tig welded. Regarding entry to the Association, the only clear cut criteria which has been agreed by all the participants is Public Liability Insurance. The long term structure and function of such an organisation I am sure will evolve over the years but I would like to think there may be a place for Amateur and semi-Professional builders within it. The current forum is being co-ordinated by Phil Taylor, organiser of Bespoke Bristol but he is keen not to take responsibility for fully organising an association as he obviously has enough on his plate with the show. As a preliminary move I decided I would have to investigate Liability insurance as even though I have never sold a frame for profit it would be nice to have the cover and indeed even making frames for friends and family it is a sad fact of life that one would be wise to have some indemnity against frame failure leading to accidents etc.
