slingy countershaft drilling?

[Guest YoshiJohnny]

digging through some boxes today I found an intact slingshot 750 six speed gearbox with all associated shifters and drum etc etc

Now to make it work on my 1127 it would need the countershaft drilling for the push rod

Does anyone have a contact for drilling it (it's hard as fook) or spark eroding cheap??

cheers

Tungsten carbide drill should be up for the job......I don't think the countershaft is harder than 65 rockwell

Suspect it'll only be case hardened - once you're through the case, you should be right.

I'm doing a six speed 1127  swap at the moment, my next job is getting the countershaft done, I'll let you know what I come up with.

Just use a quality drill , all of my 1100s are 6 speed I just use some old imperial drills that were made in England.

Aren't teapot-boxes the same, but drilled?

drilled easy peasy

Really, did you find a long reach bit or did it need spit roasting?

This is something that has been churning in my mind for a while and have been wondering how reliable the shaft would be.

:chin scratch:

Not that I'm thinking of Endurance engines, Oh No.

The GSX one is already hollow - just full of "pressure" fed oil.
