Re: <R35> - Adhesive Tape

Elgin,

The further out your chain is from the side wall, the larger the bending forces on your tensioner. So, you either need a bigger/stronger bolt, or you need to reduce the load on the bolt. You can either bring the chain in closer to the wall, or create a wider base on your tensioner. The wider base will help counter-act the bending load in conjuntion with the bolt. We typically use a 1.5" - 2" diameter HDPE rod and if required, we'll turn down the center of the OD to create a flanged tensioner.

The grooves you're finding in the tensioner will develop over time. The harder the plastic you use, the better. HDPE, Acetal, Delrin are all good choices. Polypropylene and Teflon are softer, and while they provide excellent low-friction surfaces, they also wear away much quicker.
