Just use corkboard from Wal Mart and some good super glue. I did it some time ago, you may be able to search what I've posted up in the past to find it. It's been at least a year ago or maybe less, I don't remember... But anywho. I guarantee it to work. They've lasted in my Airsal powered Tomos for some time now, and man is it cheap if you need to "reline" them.
