There shouldn't be excessive forces. After all, the only load

Actually, this isn't quite true. There's a force lifting the rear of the
carriage whenever the tool is cutting the outside of the work (i.e., not
when making a facing cut). Therefore, you should expect the rear to wear
more than the front on the bottom (and perhaps the front to wear more on
the top).

Point well made, I hadn't thought that far ahead yet but I can see it as you say Mike. As far as excessive John, for most of us I suppose that's true enough but I've also seen personal sites where the tool has been hung so far past the bed I wondered why not just buy a bigger machine. Fellows are always trying to make this thing run "larger" than it is.
Fair 'nuff Marty.
I get down to detail in electronics stuff where I know my territory.
No qualms about ripping commercial gear apart and redesigning. This
stuff is out of my territory and went counter-intuitive for me so I
figured I'd raise the query.
Later,
John

I know what you mean John. Within our "field" we tend to break it down to nothing and rebuild it to what we see as the "ultimate" design. I think it is when we observe from outside our "field" that we get that counter feeling. Remember when I asked the meter question the stir that rose? Playing outside my park :) Ya know, a bunch of bright guys would pool at that experience.
I lead with a link to an excellent article. Mineral verses synthetic lubricants. It will make you think twice about Mobil 1 for way oil if you understand the viscosity-pressure coefficient data. Room temperature being one of those areas where it's just hard to beat a good mineral oil. Give it a read and tell me what you get from it if you wish.
