I found some rails that I like on E-bay (THK SR15) however they are a little bit longer than I want.

My questions is: Can rails be cut to size, or is this something that should be avoided?

Thanks

You should have no problem cutting them. Go get yourself a cheapy right angle grinder with a cutoff wheel. Hacksaw won't touch the stuff. Make sure you don't over heat the rail where you are cutting, use plenty of water, but be careful, water and electricity dont mix. Cut, apply water, cut, apply water,...........might take a while.

If you don't already have a right-angle grinder, you can also get a cutoff wheel to put in your Circular Saw to make the cuts. And they are cheap.

Awesome guys......thanks! While I'm asking about the rails...... I want to use 8020 extrusion for the frame and to mount the x rails on. Should the rails be mounted on the solid side of the extrusion, or can they be mounted on the track? Any pros and cons here? Thanks everyone for being so helpful!!!

Be aware that extrusions aren't flat or straight, and the rails will conform to the extrusion. They may be straight enough for your application, though.

I see a lot of designs using 8020 and such....how do they do that if it is not flat or straight?

Thanks

I haven't used 8020, but page 38 of this pdf http://www.8020.net/PDF/Fractional%20Section%201.pdf says that they are only straight to within 0.0125 inches per foot of length, and flat to .004 inches per inch of width, and twist per foot of length will not excede .25 degrees.
