however I will go to my shed and have a look for you Michael as you never know I might have what you need in my bucket of assorted old taps and dies rick

thank-you
Thanks Rick, e-mail sent to you.
I understand the BSP series follows the standard, non-modified Whitworth thread profile. What I have not found is a 7/8 x 14 in other than BSP. Sir Miles Axlerod from Cars would be impressed. A trail of redundant threads. "And then I remembered what they said about old British Engines, if there ain't no oil under 'em, there ain't no oil in 'em."

I think you guys are barking up the wrong tree HOWL
That thread is an engineered thread specified by the designer 1 .187 x 14 threads to the inch This is not unusual when design work is going on The engineer has specified what it is doing and the weights and torques required And the shaft will be designed to those specifications Remember guys there was not a lot of metric going on in Canada during the war yeas just my opinion again and you are all welcome to put me in your sights

As for metric, you may be surprised to know that metric sized bearings were used by Ford in the gearboxes. regards Richard
