I have looked through the M2 build thread. It would be nice if we could potentially arrange a group order for some flanges to serve the purpose of the flange 5026224 that is currently $120. The addition of holes to mount the 2451, with the larger bolt pattern, would also allow more people to try out the M2 horns. Forgive me if someone has already offered such a device. I know you have to pay to play, but it seems like a part that should be included in the price of the horn. If it was $60 I would have no problem buying them, but $120 is hard for me to spend, it I don't need to.
My brother is a machinist, and he has fabricated aluminum bike parts for me in the past. However, he would not be allowed to produce hobby projects at his current job. I would be interested in 3 flanges.
