Hello, I've been offered a couple of Ariel projects that aren't titled. I can get the police to check that they have clean records tomorrow during business hours, but I was wondering if there was any history with the club or factory history. 1937 350 engine BC1382, frame XF9471.

(219 + 201)/649 = 0.647 balance factor. The small end weight goes in the denominator as well, which means your balance factor is 0.494. It's in there. Reciprocating mass = 448g (piston, pin, rings & clips) + 201g small end = 649g. So (219 + 201)/(448 + 201) = 420/649 = 0.647 Oh, you gave me a s...

The oil passage was confirmed by squirting oil into the timing side mainshaft and making a mess. The assembly was then placed on the truing stan...

OK - time to put this thread to bed... So my purpose in starting this work was to see if I could save the crank of my '46 VH project. It was a lot of work but seems worth it. Mainshafts were both chucked in collets in the lathe and showed minimal runout. Nuts torqued to 125+ lbs/ft. New wrist pin bu...

Thank you Vincent. Peter's classic bike parts is a good resource I didn't know about.

Feked had the 1/4" rollers and some other bits I could use so that is where I ordered them.

More great pictures!, Looks like a lot of fun.

Great pictures, thankyou.

Wow, that's cool. You have some big tools and know how to use them. By ceramic bore, do you mean nikasil? Is it a sleeve or a coating? Look forward to seeing more.
