I think everyone remembers my old car, the black one. I built it in a 12 X 24 self storage garage with almost no equipment.

I built the whole thing with a bench top drill press, a band-saw and a Craftsman bench top belt sander. It was not easy, in fact that is why it took almost 5 years to finish. It wasn't until the last couple of years I started to buy my equipment. If I had to replace everything I have with all new stuff, it would cost just under $100,000, not an easy nut to crunch. The point is if there is a will, there is a way.
The work I do now is mainly maintenance machine. I'm handed a beat-up sample of a part and I'm expected to make a new one that is perfect.
The bulk of my work is in pump repair, pump shafting, shaft sleeves and impeller rings, nothing fancy but it puts Cheerios on the table.
I'm a job shop machine shop, I can make anything for anybody, providing they can pay the price. The going shop rate in this area is from $50 an hour to $80 an hour depending on what's needed. The reason for the seemingly high rate is to pay for the expensive equipment I, we need to do the work. Takes a long time to pay off $100,000 at $50 an hour. Not to mention the years of experience it take to do the work.
As far as making a set of hinges for folks, no big deal except it takes almost a day and a half to make a pair of them, lot more work than it looks. Even at $40 an hour, a set of hinges can cost a bunch. Now as much as I consider myself to be racer/buggy friendly when it comes to pricing, I find that most into buggy's are not willing to pay that price. Example, my double shear torsion eliminators, everyone wanted a set, no one wanted to pay for them, my ball joint to link/pin conversion arms and spindles, everyone wanted a set, no one wanted to pay for them. I can't be expected to give things away and stay in business for very long.
The long to short version is, unless you have a buddy that has the capability to do machine work for cheap or nothing, it's expensive.
Still want a set of hinges? PM me and tell me what your willing to pay, taking into consideration what it takes to do and I'll tell you if I can do it.
