I am looking at a BP series 1 that is going to cost me about 500$ and a few hours of work. Nothing major. The machine is said to run but that doesn't really concern me too much - I have plans of adding an Ajax/Centroid controller which should do away with all of the outdated controlls.
The questions are - What is the air cylinder for that is on the front/top/left of the machine? Is it for the PDB?
Question #2 - what is the cylinder with the attached hoses on the oppsite side of the head? Spindle speed control of some sort?
Question#3 - What taper should this machine have? (it appears to have some sort of quick change small taper on it now, something like a quarter turn to release the tool..I thought it said something like "quick change 20", but I can't find it anywhere)...
Assuming all of the controls were no good but the ways, ballscrews, and motor are in great shape - would this thing be worth 500$??
It is just like the BP in this link:
