Not sure if this applies to Post Classic as it does for classic, but, is a 'new built' but replicated chassis of an original from the period eligible for PC ? I think their cut off date for using an original chassis was '81/'82 but unsure if replicating one would be allowed ??

I am sure this is permitted, to confirm this get in touch with Stuart Mellor.

Frames were originally brazed but current thinking from on high seems not to like that idea. I've always understood that a braze allows slight flex of frame under stress but then you may call me a sweet, old fashioned thing. Know which I prefer ...

That's what I was thinking Bob, everything I came across from that era seemed to be brazed, as you say allowing some flexibility, and also if the type of weld used would then either allow it's use or prohibit it .......... i.e. is the type of weld used also scrutinised so as to ensure it's dateline ?? ..........

A
tidy Tig-welded or brazed frame both look good

I may be wrong (usually am

) - but I think it might be more a case of which process suits the type of tube being used - some materials are better suited to Tig - some better suited to brazing...?
I'm sure there are people on here able to comment with a little more authority...
I really don't know you well enough to call you a sweet, old fashioned thing though

Gordon,
Don't worry if it's brazed or tig welded or in trying to keep to that period or era as i don't think they were tig welding
classic frames back in the good old days but tig welding seems to be accepted in the classic scene now a days !!!!!!!!!!!!!!

Certainly weren't tigs in the 60s. Many outfits started life as Featherbed frames all of which were brazed and it was logical to braze when other bits were added on

I would suggets cds,as outfit frames have a hard life,best you braze,as its easier to repair in a paddock at a race meeting,not many people take tig welding sets to a meeting.
