Re: Attaching Plaction Tread to Delrin Cylinders

We have been using tiny wood screws on UHMW wheels for many years and have never had any issues. We also did this on Delrin rollers last year, makes replacing the tread very easy.

When we replace the tread we attach it again in a different spot and never have to worry about lining up with any existing holes. Works great.

We actually make Aluminum wheel "rims" and an outer disk of UHMW just so we can easily replace the tread using small wood screws. All you need is about 1/4" of material and maybe 6-8 screws per wheel.
