I used to have a 500 and a 600 and collected some restoration books and magazines, I'll see if I can find them for you. I'm unlikely to get back into British bikes.

Buddy of mine rebuilt a BSA awhile ago, got heaps of assistance from, I think it was the Perth vintage club

OK started pulling the frame apart and frontend off today. Spent most of the day playing is it metric or is it imperial with the spanners ," lost a bolt I rekon this one will fit"



The rear supports are cracked and will need to be welded and I think the forks will have to be completely replaced as the have rusted all the way through.



Also for some reason the first guy that owned it decided to cut the front engine mounts and about 2 inches off the down tube. So i figure i'll have to machine up a plug, insert it in to the tube weld it then make the engine brackets.



Once I get back to work I'll give it a good sand blast and machine the insert for the downtube . First time I've actually wanted to be out on night shifts

Subscribed, looking forward to how this turns out, would love to help out, be a great learning experience for me.

Do you have to worry about Whitworth threads on BSA's?

Great project, looking forward to seeing it progress

Two thumbs up. You have a lot of work ahead, but it is going to be sweet when it is finished

[Steady Steady]

Pretty much ever bolt is stuck and every time I get one to turn it snaps . When it comes to bolting the frame back together i'll have a look . Iv'e got the workshop manual coming for it in the mail . But I would image cause of the age yep

Pretty sure they are witworth. I rode a c12 bsa on the indian harley club two day rally in bunbury a couple of years ago.

Good Luck - I actually restore Brits (the Yamaha was just a once-off), so I feel your pain - rumor has it that when the guys used to build these bikes in the UK, whatever the storeman gave at the time, was the tap or die you used. So you could have a mixture of Whitworth, BA and BSF all on the same bike!!!!

11mm comes in handy

I rode an A50 Royal Star there last year. I'll be on a Suzuki Katana this year. Talk about a massive change of pace.

BSW (whitworth) is interchangeable with UNC (American coarse) up to but not including 1/2" as its only a different thread angle which wont make that much of a difference. I doubt they would use much, if any BA on it apart from in the carburetors. But there will most likely be alot of BSF and BSC (British standard cycle) which is mostly 26 tpi.

We have made a few replica Jaguar carburetors, where you come across threads like 1/4" 46 tpi and other nasty sizes which you have to make taps for.

Have to love restoring or replicating something that is British..

I suggest buying a set of verniers and a thread pitch gauge

I know I may be tellin you how to suck eggs, but if you haven't already tried have a look at the loctite freeze and release spray, it has made stripping old cars really easy and less bolt snapping for me. Might help! Awesome
Project by the way!!
