This is not just a build log, but also a plea for community support! I have little money, and few tools, but I really want my own machine shop. I feel like the first step I should take is to build a self-making metal shaper. The core of the project will rely on the accuracy of a purchased "GNP" (ground n polished) steel rod, and my own technical skill in metal working.
My plan, for now, consists of making a "sliding cartridge" using split and polished brass bushings held in place by bolts inside of a split peice of steel tubing, which is itself inside a steel tube with accurately handmade slide holes for a rod to connect the ram to the rest of the machine. The ram will be stationary in construction, providing the accurate reference point for all the rest of the cartridge's parts, allowing for reasonable straightness and accuracy throughought, independent of accurate machining operations and techniques.
Basically, because the rod is precise, a carriage made around it shall also be precise, if it can all be held in place, perhaps through positioning with bolts, and then permanent fixturing with epoxy. The machine'a bearings will be oiled, I think.
Once the ram is made, it will be linked to a base plate, and a clapper mechanism will be developed, as well as means of transferring foot power to a main gear, which will also connect to a power cross slide.
