So, I was given plans to build an 18" saw. If you spend any time on ebay, you've seen 'em for sale. Seems simple, but effective. This will be a big project for me, but I'm pretty excited.
Anyway, one thing that has me concerned is the vise carriage runs on round rails, mounted on two plates with holes drilled in them which simply slide over the rails. (If you're having trouble visualizing this, there is a photo of a saw with a similar design in the first post of the "slab saw sucker" thread.)
I'm reassured to see at least one other saw with this simple design, but I'm concerned about drag on the feed motor. Would it be worthwhile to put nylon or other low-frictiin sleeves in those holes, or do you think abrasive-laden oil spraying all over would just eat them up?
Experiences over the longer term with designs like this? Thoughts?
Thanks in advance, Argh

Anything that reduces friction is best.

The guy I know that builds saws similar to the Royal style saw plans put delrin bushings on the saws he built to sell. In order to do that you will need to be able to line bore the carriage and the end supports for the rails so everything lines up tightly. My 10 inch saw has plain old drilled holes in the carriage for the rails and it works fine. At an inch of travel every 5 or more minutes drag is not a big issue IMO.
