1970's era crankshaft repair

This is what I did when the the threaded part of my crankshaft broke off on the fly wheel side. I started by chucking the crankshaft in a lathe, used a dial indicator to center it, then used zip-ties to hold the connecting rod in place then I spun it at about 160 rpm's and used a cutter to take what was left of the threads off it is really hard material and it took a little while then I took a centering bit to drill a pilot hole, then used a 25/32 bit to drill the hole then tapped it with a 7/16 bottoming tap about 3/4 of an inch in then ill use a 7/16 grade 8 stud and install it with red lock-tite but this flywheel shaft is the larger .755 one I dont know how the smaller ones will work, Rick Horvat told me that this can be done he also has the crank pins, and crankshafts and is very helpfull if you have any questions but heres some pictures of what mine looks like hopefully it will help someone in the same boat it took me about 2 hours to do and I'm not an expert on the lathe but 2 hours is about what a machine shop should charge
