the wife wants to put one of those grass skirt deallys on the back of hers. would definitly be very flimsy and would fold out of the way when stuck very easily.
FIND A gravel pit that has a crusher working or has worked , evan better, the belting they is great . Is found in differant thickness ,widths, and miles of it ,most often for free or please take as much as you can,
Not sure if it would work or not, but what about a piece cut out from an old treadmill belt. Heck if the ol lady is just using for a clothes rack, just cut a chunk out and rotate it to the bottom. Just kidding. I picked up some at the local recycling centre, (dump) for $0 dollars for used on my sled trailer.
Here is the pic - not hard to make, just a bent piece of aluminum. You could make the kick out more if you needed to get it farther from the track too.
Treadmill belting might be too light - a heavy truck flap will be pushed back out of the way when you get on the gas hard.
