dw10 crank swap 400HP

[Uberderv]

Main thing to know is that you have to make the spring stiffer so lets your engineering skills do the work... ;-)
I used a small allen key "headless" bolt M8x10 (don't know how they are called in English, it's all treated a little point at one side and the internal hexagon on the other, used in mechanics/agriculture) and in the lathe made the point look like the drilled out part. (only a few millimeters shorter since that is also the "ball stopper")

Grub screw?

 Awesome work BTW
