I don't run into pool table mechanic's very often as 99% of the work done to pool tables is having the cloth replaced, and replacing the cushions, right or wrong. In my opinion, it takes a lot more skills to be a pool table mechanic than what meets the eye of the customer, so the title "pool table mechanic" is thrown around very loosely. Yes, there are professional installers like PT911, who take a tremendous amount of pride in the work he and his crew perform, but he's 100% right about most everyone working on pool tables, as most of them OTHER out there only know how to "price" the work in order to land the job, and there's plenty of stupid customers willing to pay for cheap, with lack of knowledge on how to perform the work correctly, and for those customers I have no sympathy, as you get what you pay for. To the OP, no matter how much you think you'd like to go into this link of work, all I have to say is this line of work will decide who comes and goes, not the person trying to just make a buck!
