yo one and all

id like to know the thickness of a camshaft standard woodruff key please, needs to be fairly accurate (mic or vernier caliper)

I could sort it out myself when i get home but i could really do with knowing before i leave work so i dont lose a day in the garage.... id tell you the reason why i need to know but im embarassed so i shant, unless you can tell me the dims and then i might consider telling you

anybody? you could save me a hell of a lot of filing if i could just pick the right bit of gauge plate before i leave work im making one by the way... a bespoke & slightly strange one

i am curious as to know why... especially as new ones and offset ones are soooo cheap

because im an idiot. rather than take the key out the cam and check it when the sproket didnt fit, i thought id fettle the sproket keyway out. Suffice to say that it wasnt the keyway that was tight, it was the bore of the sproket needed polishing. So, now i have a sloppy woodruff key. Im making my own stepped one to fit both my bigger keyway in the sproket and the standard keyway in the cam.

its around 5/32 gauge. I'm making mine out of titanium... because i can

to be honest - you can run it without the key in place... key is only there to position it, the nut holds the sprocket onto the cam...

hmm i suppose... but what about timing? i cant torque the nut because i cant lock the engine yet... and if there is no key then surely there will be some movement and therefore timing will be squiffed

then again, i could just wait for my 'box and lock it... hmmmmmm

[icklemini]

will be no movement when the nut is tightened up... throwing the key away can get you past some racing forumulas technical regulations...

If the sprocket is on the cam nose, nut tightened up - then it wont move... the key is only to assit in positioning it..
