Thanks, Glen, just a few minutes ago I looked at what I got after a lot of bending - not sideways - and quite rightly there is substantial offset I did not notice. Or better say I left them as they were in this respect. Have not yet decided what rear hub I´ll come up so still scope for anything that might turn up to get sprockets aligned.

I think I put the offset on here for one of our friends, Maybe "Oldhaven" ?,
I have one bad eye and looking at it on the piss, drove me nuts !,
Lucky I had another Frame in bits to compare,
As Davidd said , How did I now the spare one was right ??.
All my Bikes ride fine, I have road raced them all !.
With out taking the bolts out and poping the top tubes out,
I think it would be very hard to get it right ?.

Hmm, I think I´ll have to deal with what I find when rear frame is set and no more bending planned - which I´d try to avoid at this stage. The sprockets have to be right foremost so possibly some mods on wheel bearings resp. spacers may be the consequence. To get the rims centralized you can do a lot of offset by spoke tensions - which would be the final job.

Thanks Trev, I try to remember your tips.
I must admit I have never checked it myself, A lot of modern Bikes are always changing
Sprockets and chains, But I have not seen much wear on my Sprockets.
All The Best, Bill.
