    Post Mill design

    I'm finalizing certain parts of the mill design so I can draw up a cutting schedule for the rod ways. I am constrained by the size of certain parts and available materials. I have a choice however on how I build the X axis. The easy way gives me ten inches of X travel. The hard way which is also a bit less elegant gives me 11.5" of X travel. How much do you think an extra 1.5" of travel is worth?

    You can never have too much travel, especially in the X axis.

    If I had a mill with a 60' table it would still come up short by at least 1-1/2"

    Coarse its kinda like asking "gee would a 10" tool be better than a 11.5" tool? On second thought just build the 10" and buy some of that cream

    Ha ha. Anyway, whatever travel you get will not be enough, so I'd be inclined to do it the most rigid way (npi) if there is that option.
    I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

    In addition to a larger mill, I have a minimill. It has a 9" travel in x. I use it a lot - maybe half of what I do. So for lots of things I do it is great. But the reason I bought a larger mill was the other half. So I would make the travel as large as possible if it were me.

    I figured that's what you guys would say. The rigidity is essentially the same either way. The hard part of doing it the hard way will be the need for making four holes 1 5/16" dia accurately placed in 3/4" stock. I have to be extremely careful not to wreck parts in this project as some of the material I have is just enough to make what I need. One screwup could result in long expensive delays.

    Weird,

    Where can I get some of that cream ?
    Does it work the same on both axis ?
