Homemade Sheaves – Nylon or Acetal?

A quick search of  many “hobbyist” websites’ plastic forums will display for you a number of sheave projects amateur machinists are working on. The appeal is obvious, a sheave is a simple stock shape used in a variety of home applications including furniture, boats, trailers, etc. When small quantities are involved it can make more sense to fabricate these on your own rather than get a fabricator to do so.

Two materials are primarily used: cast nylon and acetal. We wanted to share a little information about both choices:

Nylon:

A robust material that can handle heavy loads and is both abrasion and wear resistant. Nylon is fairly easy to find and cost-effective for most sheaves. Nylon-Virgin

Acetal:

An easily machined and very hard plastic, acetal is known as a nylon replacement – especially in “wet” or marine applications. Sheaves for boating are a fairly common application – and in that situation acetal should be your choice.
