Schwintek slide improvements

If you have 2 sets of gear rails down the sides of your slide, you have a Schwintek. These slides have 2 or 3 white plastic rollers underneath that will eventually cause wear, destroying the undercoating or even channeling into the the wood floor. Yous can see bits of the undercoating sticking to the rollers in the photos. Here is a solution. I used .05 mil aluminum plates 7 inches wide that I had done at a metal shop. Cost me about $25 for 3 of them. In my case they had to be 36 inches long to just tuck under the molding. I did not want the molding snagging on the end of it and wearing as it went in & out. The rollers are 4.4 inches wide so there is lots of room on each side of them. I used plastic screw head inserts so the molding does not wear as it passes over them.

The pictures below illustrate the issue and the final product. I found I had to jack up the side as close to the trailer body as possible and only raised it enough to force the aluminum over the rollers. the drive motors have about 1/4 of play so the extra 0.5 mil height is not an issue.
