What it the best approach?
1. large enough ø to mill a decent hex and turn the rest down to ø13mm
2. buy the smallest ø that I can find to thread and then either pin and/or weld a larger ø piece from which the hex can be milled?
Option 1 seems wasteful but I have heard of people having issues with pinned drawbars. I know 1018 welds fine but I'm not sure about 4140
