Hi Meredith / Dale,

       The cheapest suspension which seems to work well is a 3/8" to 1/2" 
Stainless Steel Ball Bearing rolling on strip of SS cut from a Skin Graft Scalpel 
Blade. The blades are 2" long, 5/16" wide and 0.016" thick. You can cut five 
strips from each blade with a carbide disk quite easily and they cost about 
$1. I stick them to the end of the arm with two part acrylic adhesive eg Devcon 
'Plastic Welder' S-220 22045. I haven't had any problems with the suspension 
wandering.

       I prefer to use just two crossed rollers with a Lehman suspension. If 
you are building a vertical, you can use two vertical rollers on the upright 
and a horizontal roller on the end of the arm.

       Regards,

       Chris Chapman
