It is 3/4" Whitworth.

Wouldn't Andy notice that? 3/4" being less than 25mm(1")

Whitworth sizes were based on the thread diameter not the distance across flats on the bolt head - therefore a 3/4" Whitworth is considerably bigger than 3/4" AF

So thats why whitworth doesn't make any sense whatsoever!

yes!

Luckily, my dad gave me all his old whitworth (some might say "worthwhitless") spanners so I just try at randon till one fits.

Is that about 33 - 34 mm,
Can you still buy whitworth anywhere apart from car boots ?

cheers

Yes. I bought one on the internet but can't remember the name of the tool company. Do a search for Whitworth spanners.

Anyone know where you can buy a deep socket the correct size to clear the starter dog? Only I'd like to tighten the front pulley bolt to the correct torque without guessing with a spanner... any ideas? or what do other folks do?

Bought myself a 3/4 whitworth today, 17 quid

so if anyone wants to borrow it it would be cheaper for us to post it to each other

Never seen a deep socket that size Cam.

Could always weld your spanner to your torque wrench

Search for whitworth on ebay & you get loads of spanners, sockets etc also very readily available at rallies, autojumbles etc. - I dont think I've ever paid more than £2 for a spanner

I purchased a 3/4" Whit ring spanner at a car boot a few years ago, as Rog says only a couple of squid, cut it down to about 7" and now use it as a "flogging" spanner. A few or less, hard or less smacks with a 4lb hammer usually releases the nut. Never failed yet.
I just tighten by hand using a non cropped 3/4" - 7/8" Whit ring spanner remembering I will probably be the next to remove the nut!

Well, it was just a thought... amazing isn't it with all the technology today, you STILL can't get a 3/4" Whitworth socket for a starter nut!

Hello Onne,

"So thats why whitworth doesn't make any sense whatsoever!"

Well, that depends on what you were brought up on, when I did my apprenticeship, it made perfect sense as we did not have any American or Metric threads in my industry. You soon got used to the other confusion of post war Whitworth sizes being 1\16" less spanner size than bolt size as metal was saved by reducing the head size (3\8" Whit fastner, use a 5\16" spanner.)
I also seem to remeber that the Whitworth thread form is superior to both the UNF\UNC threads and the Metric threads, progress??

A clever man Mr Whitworth. He invented and manufactured a rifle which had a spiral hexagonal barrel and bullets to suit. Highly accurate. He'd calculated the best spiral for velocity and accuracy. At the time the British government refused to buy because of cost. Whitworth sold the rifle to Confederate forces during U S civil war. It is reported that some Northern general was walking up and down his lines in full view when under fire from Confederates who were using Whitworth's rifles. He was shouting to his men "stand up and fight you cowards, they couldn't hit a barn d------------------"

"at this distance, they couldn't hit a barn d..." surely?

Hi Cam

A 3/4 W box spanner fits nicely - now I'm not into this welding lark but I'd have thought a man of your hairstyle could weld a socket adaptor thingumijig to the end of the box spanner to fit your torque wrench to ? or is that not feasable.

You see, I was waiting for someone to spot that one...

Yes, that could certainly be done but I don't have a spare (or any) 3/4 W box spanner!

Do you have one spare that I could purchase or maybe a hunt on eBay...

I'd have thought a man of your hairstyle could...

Made me laugh that did!
