Being tedious is my point. Gage blocks and indicators were created in the mid 1800's. So precise measurement has been around a while. Laying out a drive setup with a height gage and drilling holes on a drill press will work, but you still need to precisely measure the hole locations if you want a smooth, frictionless system. I'm sure the Wright Brothers used Gage Blocks and indicators to build a gas powered motor. You can't get a precise piston to wall measurement from a pair of dividers and expect that the piston will not sieze or rattle itself out of the bore. Or correct oil clearance on the bearings without a bore gage.
You can only hold as tight a tolerence as the machinery that you have to work with. The better the tools, the better you can repeatedly hold a tight tolerence. Modern machinery dramatically reduces the time required to Accurately machine a part, and beinng we are only given 6 weeks to design and build a robot....all the time you save...
