while messing around with a homemade uncoiled spring for a extra light tension tool, i got bored and starting use a regular
double ended one in the top of key way, then put the spring on the bottom and coiled to the to the back side of the other tool
giving pressure in oppisite directions. the regular tool felt the same except when counter turning it had no play at all. I've made
a few different falle safe style one and while they have little play this had none. im moving soon so i sort of miss placed it
but it took like five mins to make the first one. when i move and get regular home internet(not just phone) ill either find or
make one just for that purpose( i made it a little to big but it fit pretty good for klikset and a few shlages). i believe there
while there are tonnes of different picks ,not a lot of innovation(how much springy the tool is and top, bottom or both, is most of it)
has been done for turning tools other than saying more practice(which is true).i believe accurate control of the rotation angle is more important to finding the setting order(which pins drop where) than the binding order(think what happens if u have spool and barrel pins, to the binding order)
