Re: pic: 1726 week 4

The tensioner is nylon because it tends to self lubricate as it wears away. The piece was machined on a lathe--it was simply a matter of cutting away a little from each side of a thin piece leaving a small runner to guide the chain (you could also cut a groove)--I'll see if I can get some more detailed picture later.

We have been using nylon for tensioners since last year and have little visible wear on it even after two regionals.
