molnar barrels

Thank you Paul-- I've already tried that.

Thanks Howard, that's just what I'd suggested in an email to Andy Molnar because I had a nut bolt and washer that I bought from him ages ago and the nut and washer looked just right. Think he's washed his hands of me... I wanted washers for the three nuts that tighten from below - he supplied small sleeve nuts and said that there was no room for washers. I particularly wanted washers here because there is a defect in the machined surface, where the cutter has run a v in the fin and left a ridge where the nut tightens to. I would have asked for a refund but didn't see it until after I'd drilled and tapped for the grub screws for Jim Schmidt tappet holders. I've had the barrel two years now but it went back in its box while I saved up for pistons, cams etc.

I've sourced some smaller hex nuts from the ever helpful Will Horgan of Stainless Classics but he didn't have small diameter washers.

With the standard size nuts, there is no room to get anything but a severely weakened open-ended spanner... the nuts are so close to the barrel, I can't even get a fag paper between.
Anyhow, thanks a lot and safe riding.
