feeling the love off this thread, really appreciating the help & offers, then again I’m just back from the pub and bit psihed.
Ok, obviously some of you aren’t reading all the posts, so I do a little explaination again to bore you silly… 🙄
I have a m8’s Marin B17 a 1998 full-susser with M10 FT holes on the swinging arm, from around the at the start of the disc brake usage , (hense why it isn’t today’s normal M6 size), engineer m8 used his thread checker gauges to confirm the spec (after he’d given me a normal M10, a whitworth & an old american bolt to try),I have an adapter made from a Marin/ATB autocad drawing again sorted by my nice engineer m8 which fits just nicely onto a 160mm disc and looks to line up with the M10 bolt holes. BUT the adapter is designed for M6 bolts. So I need the M10 F-T bolts so that they can be drilled and tapped for a M6 bolt, have the heads cut off and this used as an insert (locktited in) to the swinging arm.
Simple eh?
will sober up and try to reply to some of the offers tomorrow.
err and Coffeeking, I’m in the stourbridge area, though travel to below oxford a couple of times a week if thats of any use.
