We have a four wheel power feeder on our shaper that has the yellow colored wheels which I think are made of urethane. The problem is over the years the wheels have lost their elasticity and as a result dont grip the wood very well.
We have glued a 3 foot piece of stroke sander belt to a piece of plywood and clamped that to the table, then sped the feeder up and set it on the sandpaper to resurface the wheels. This works for a short while but I would like to find something to soften the wheels. I have heard of a chemical for softening the feed wheels on printer feed rollers. Has anyone found a way to soften these wheels?

From contributor M:
We have siped the wheels for better grip by cutting small grooves across the wheels on the bandsaw. This is a temporary fix as I think they just harden after time and need to eventually be replaced. Western Roller is a good source.
We found that to switch to the replaceable system offers many advantages. The ease of replacing tires in house is one. The cost is another. Having to have another set of rollers on hand, while having a set recovered, plus the time and cost of shipping on a fairly low dollar item is not very cost-effective. The tires used are a high quality urethane and a longer lasting than stock OEM rubber tires. They are also non-marring.
Here's an information page on the Western Roller Super Feed system. The SFH-1 hub is very common and uses a SFT tire that is available in 50, 60 or 70 durometer.
