(Pipe dream: Maybe my sons can be the next Olhausens.
Sometimes it works, sometimes it doesn't. John's boys were brought into the business at a young age and did some of his commercial table work in the bars & such. But they died, one by one, of drug related causes. He had hoped they would never have to come out of appalachia during the depression like he did and struggle to make a very good life for his wife and family doing demeaning day work he hated. Unfortunately, they mostly hated having to do table work on dad's scheduled appointments, though it gave them good money & great reps in the pool & fast life communities. His last is a good kid, was really good in the shop, but had congenital bone problems that led to medical professional induced opiod addiction before people really understood that.
If you just want to think and talk about it, stay on AZB.
If you decide to get some equipment and start building, you can ask questions and show your work on my forum on PM. We can be rough but i'm on a dozen forums from Aviation to Woodworking, and don't think any can be as rough as AZB :grin:
(Actually what i like here - it's real)

Not sure there are any currently who could tell you specifically how to build a pool table though one never knows who is lurking. However, we can tell you how to use/adapt/modify any machine, make any sort of part or hardware, and make the cutting tooling to do it in wood & metal, if you seem to be a serious do-er rather than talker. The PM site owner has always intended PM to be professional/industrial & I try to keep the wood forum that way as well. There's some leeway but mere chit-chat (in Don's words) is not encouraged. AZB is more generous to that. You also can't talk about hobby/home owner level machines, but you can show them doing actual work, and you can ask about how to do specific tasks if the focus is the work & not the (homeowner level) machine.
Good luck if you decide to progress.
Basically, you have to start. That's always the hardest part. Start and fail forward, keep going, one step at a time.
