Puch E50 Clutch Keyway Broach Plug

I used this to cut a keyway into a KTM 50sx clutch body to adapt it onto my Puch E50.  The plug is used to guide the broach as it is pressed through the clutch body.  I used a 6 ton hydraulic press and had to shim the clutch body so the broach was vertically aligned with the press head.  This was designed for a 3mm broach I bought off Amazon.  The 3mm cutting edge is slightly thinner than the back of the broach.
