8mm pinions

When working with steel, the quicker you cool it, the harder it becomes.
To harden most steel it is heated to a medium red or slightly above the point where it becomes non-magnetic. It is then quenched in water, oil or air depending on the type of steel. The steel is now at its maximum hardness but is very brittle.

That's a damn good price. Only problem is a lack of being hardened.

SDP-SI has the 8mm shaft out of Carbon Steel and it should be strong enough.

only problem with the SDP-SI gears, are the size of the set screws... they are super small...
