Adam,

I'm sorry to learn you need to sell your 9A. I know how I'd hate to part with my 9C!

Will you still be in the group?

Will you still have your hands in making things?

I ask out of 100% self interest. I have a 1970s Viscount bicycle for which I need to buy at least one bolt. The thread is English and only available here for a king's ransom, if at all. I'd like to have a "friend" on that side of the pond who'd help me obtain them. I'm perfectly willing to not only cover the actual cost, but also add remuneration for the effort involved.

All the best,

Dave

A change of circumstances means I need to sell my 9a lathe, I'm not sure how many folks here are from the UK, but I thought the decent thing to do would be to offer it here first before heading to Ebay.

If anyone is interested let me know and I can email pics and info directly.

I was never very active on the posting side , but as I fear this will likely be the end of my Southend ownership, this seems like an opportunity to thank all those who have helped me over the years and maintain this group, especially Jim B (thanks for the leadscrew).?

Neither, AFAIK. They advertise as “aerospace tubing” some variety of chrome-moly. And yes, I was a serious cyclist in the 70s-80s.

Same for me Animal, but down here in Australia the Brooks seats were very expensive and I went for a leather covered nylon Italian made seat. It was terrific and need a lot less care and attention than the full leather Brooks.

Cheers

I have an early British Car.?
Most of the fasteners I needed were available in the US at several suppliers.?
But I have made quite a few on either my 9C or 10l.?
My car uses mostly BSF (British Standard Fine) that’s an inch based thread with a 55 degree V. There are one or two Whitworth. That’s basically BSF, again a 55 degree v.?
Machine screws are BA series. 47 degree V and sort of metric based.?

Most engine and Gearbox bolts are OLDER metric threads but with BSF hex heads.?

I suspect you may need BSCY, British Standard Cycle. Also called BSB. British Standard Brass. 55 degree V and 26 tpi.?
Here is one UK source I have used.?

?

Here is one of my projects.?
In the gearbox was a locating screw holding a ground shaft in place. ?
It had Metric threads, BSF Hex, and a locating nip on the end. ?TOP in Photo.?

Layshaft-Locating-Screw.jpg

I ordered a replacement from the usual sources. SECOND screw.?
Note that this has a standard metric Hex and while it might do the job, it’s not acceptable.?

I was able to get a used screw (third) but wanting something a little stronger I decided to make once.?

I purchased 6” of Molly steel, turned the nib, chased the threads and milled, on my lathe, the correct hex.?
BOTTOM screw.?

There have been many similar problems that an hour or two on my lathes have solved.?

You can do it.?

I restore old Simplex motorcycles which use a bunch of BSC hardware. ?This place has a good selection.

For my 9C I had found both a 100 and 127 tooth gears. Separately not as a compound. I made a compound and that allows me to chase metric on it.?

There are several other pairs that work.?
Yes you need a compound of some sort. BUT some metric are close.

BSC is just 26 tpi with a 55 degree angle. Just need the correct insert or grind one in HSS.
