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

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!
