IH has had ground ways for a couple of years now so they probably took it off. my IH mill has nice ground ways, no need to lap.

Thanks... I'm planning to lap my X3. Haven't shelled out for the big IH mill yet.

Where's the best place to get the abrasive powder? I found it on Mcmaster, but they want more than $40 per grit!

Go to the automotive parts outlet and look for valve grinding compound Another source would be a lapadary supply where they polish rocks. You don't want to go for 100% clean up which is a common mistake made ! all you really want or need is to smooth up the finish so it will slide easier, and the remaining mill marks can serve as oil gallery.
IH has been working on a brand new website and are changing everything about it so the presant site has been stripped to fascilitate the upgrade. Might be a few more weeks for the new site.
The only real info just refers to taking long full strokes with moderate over travel and a good cleanup when done. Remember that the machine was machined to fit and that lapping takes off material so in effect your loosening up that fit ! Only do enough to lessen the friction with minimal material removal.

Great, thanks for all the info everyone. I'll keep you updated with my progress.
