Posts Tagged ‘PTFE telescope mounting’

One of the few PTFE applications that brings in the DIY community consistantly to a plastics distributor is the application using sheet material cut into discs as mountings for telescopes. PTFE is the third slickest solid known to man and works well as a sliding surface. It does have very low load-bearing capabilities and is subject to “creep” (dimensional changes at rest) and also cannot handle much wear at all. In short, there are only specific instances the material makes sense – especially due to its high cost compared to most other plastics used in DIY applications.

We recently came across a blog posting from an amateur astronomer (“Chris B.”) chronicling his progress in making telescope mountings from PTFE. He gives some pretty handy tips such as how to cut the material precisely into the desired disc and to keep it from moving around. We don’t really have experience in this area so it’s probably best to let Chris’ work speak for itself.
