Hi All
I am trying to build a chair-mount mechanism for keyboards and have landed in an issue. The mechanism is couple of steel & aluminum pieces sandwiched and screwed together. The issue is since these are to be aligned nicely, there is precision involved. Unhappy to say that I have already tried 2 machine shops and one all-in-one welder/machinist and all of them produced off centered and mismatched screw holes and threads. Each of them is happy to quote me 75$ an hour and talk proud work quality but the result is worse than China quality!!! All of them have done this with CNC machines with automatic travel x-y tables. These idiots even dont know/use stubby bits and don't center punch. So you can understand what happens when the drill bit chatters. So goes American craftsmanship over small dimensions. I had very high hopes but appalled at the resulting quality.
So I am in such despair condition (who wont be? after shelling out 200$ materials and 400$ labor) I am either looking at buying my own drill press and/or using one that somebody else has. All I need is an older drill (has to be the big box non-china or if china, tuned to do precision/low run-out specs). I am drilling over 1018 low carbon steel and aluminum & the specs are in centimeter/millimeter and there are about 100-200 holes of 6-24 dia. I have bits or can use whatever you can suggest.
Anybody can help me here? Can pay for services or barter with whatever I have, or even you can have a set of your own after all is done and powercoated.
I can drive up to 50 miles surrounding Hayward, CALIFORNIA, so let me know if you have it or you can point me to somebody.
