Some excellent discussions there Ken, thank you. One thing that was mentioned in another page there but only in passing was ptfe (teflon) in re sliding ways surfaces, and I'm curious about whether anyone has compared the teflon formula that comes in a 4 to 8 oz blue bottle from Dupont from the home centers, with the performance of the typical iso 68 vactra way oil. I occasionally have trouble with both mills getting away from the end of travel because of the rather severe unbalanced binding force of the x ways when the table is trying to get back to center at the end of the homing operation. My final home speeds are about 1/3rd of what it can do when more nearly centered if I want it to home reliably. So for the next experiment since neither machine has anything resembling a one shot lube system for the ways, is to find out if this ptfe carrying lube is lower friction under this unbalanced load than two week old and dirty, drying out Vactra, when the ptfe tiger piss is also dried out. Or should I dismount the screws, remove the table, and drill the top of the Y slider so I can run some weedeater fuel line in and make a one shot I can feed from someplace on the post? I'd done it for the ball nuts in the micro-mill because they have no dirt shielding whatsoever, but not for the way sliders. What say the experts?
