You can make your own frame sliders with a little time and just a little effort. Before you even start you must make sure that you have a few basic wood working tools. Foremost, you must have a lathe. I used a 25 year old Craftsman. Second, you need to have a drill press. You can use a hand held drill, but a press is a lot more efficient. Other tools that you will need are: a combination square, back saw, hack saw, chop saw, electric drill w/ screw driver bits, a short bar clamp, 15/32" drill bit, a 1 1/8" Forstner bit and a little piece of wood. 2" Nylon round stock was sourced from a local plastic supply company. There is bound to be a place around where you can find this

For a non-s model, measure a piece of round stock that is 3 3/4" and cut it with the chop saw. Measure to find the exact center and draw an "x" on the top. For the spindle (end A) end you must cut the "x" with the back saw; the teeth on the spindle will bite into this "x". Measure down 1/2" from end A, mark with a black sharpie. Measure from the bearing end (B) 1/4" and mark with the sharpie. For end B, a piece of 3/4" pine board must be affixed with some small drywall screws. Find the middle of end B.
