That's kind of my plan Mike. The materials are pricey, so it wouldn't be a cheap tool, but if it works better than what's out there, I might make a batch here and there to help the community. I doubt I could make any money at all on them since quality acme rod stock and acme nuts are not cheap. The labor wouldn't be too bad when built in batches, but each tool does require machining, welding, and also powdercoating if I sell them.
The key is the testing to see if the tool works as planned. I have one car that has never been apart and another set of spare rear corner assemblies that are virgin and from a VERY rusty car. If the tool works on all four, I will make more prototypes for sure and figure out how much I'd have to charge.
I'd guess the price to be around $80 - $100. One issue I see is that the acme nut is huge and most people wouldn't have a wrench big enough to fit it. From memory, it is something like a 1-1/2" hex.
If the tool works and I sell zero, I will be happy. If I sell 10 and help others, that's even better. If the tool breaks or doesn't work and I cannot modify it to function properly, I am still glad I tried.
