Thanks for the info. If I can get 45IPM, I will be happy. The advantage I have is that there will be no tool force to deal with; only friction and momentum. Hopefully, I can get a little more, but 45 would work.

I am already planning on using it for the short rails. The cutting surface should be around 20"-24" so if I cut this in half, it gives me 36" of length, so I'll can have between 12"-16" long bearing blocks. I'm going to try to get these started this weekend. The skate bearings that I bought off of Ebay (40 for $15+$7s/h) were originally supposed to be here tomorrow, but now the UPS site says that the delivery has been rescheduled for Monday, so I'll have to try to put everything else together this weekend and install bearings next week.
I'll post pics when I take them.
