Hi All,
I am working on a fixture to hold a rather large object and it needs to be cut from a non-conductive material. It needs to hold a grab onto the lip of a cylindrical object. The object is 23" diam, the lip is 24" diam and 1.250" thick and it weights about 80lbs total.
I'm considering using two pieces of 36"x36"x3/4" thick material and cutting out a center opening and then cutting a recess that would clamp onto either side of the ring. That said, I'm not really sure what plastic would be the best choice.
McMaster is near me, so I tend to order most of my raw materials from them, and in this size I have the following options:
Chemical Resistant PVC
Easy-to-Machine Impact Resistant ABS
Impact-Resistant UHMW Polyethylene
Abrasion-Resistant Glass-Filled UHMW Polyethylene
I'm leaning toward the Polyethylene right now, but I'm not sure if there is a better choice. I don't have much experience with plastics (being an electronics guy), so if there are any veterans here that could make some suggestions I would appreciate it. I need to be able to support the weight in both the plane of the material, and perpendicular to the plane of the material (the fixture rotates to allow for loading/unloading of the cylinder).
