TB2 - Roller and pin

[JMe]

Hi
i am planning to order some "inch" tools and steel rods before i start to machine parts for TB2 and TB3.
Please, may you advise me a good steel choice for making the rollers ?
Must i plan to ream the hole or a carefull drill with plenty of cutting oil and a new drill is enough ?
Must these rollers be heat treated ?
Is 1/16" a definitive choice for pin diameter ?
Many thanks in advance for your help

The rollers do not need to be hardened. Any steel will work fine. A free machining steel would be the easiest, but what ever you have and are comfortable with. A drilled hole will be fine. This not a high speed application and the force is always in the same direction on the pin. The 1/16 diameter pin could be changed, but the hole in the forks would also have to be changed. If you and whoever is making the forks could agree on something different that is not too much different, then that would be fine.

Jacques,

I'm your fork guy :big: Let me know what size you end up with. Are you thinking something other than 1/16"
