I am experimenting a bit here. Since the bend brake is having problems holding the material in place, I decided to take a closer look. I took the upper angle of the brake apart and noticed the points where the aluminum had slid. I immediately realized that the surface area of actual contact between the aluminum sheet and the angle was very small. One would think that the angle's surface is flat enough.. but it really isn't, specially compared to the aluminum sheet. So as to increase the area of contact between the two I decided to add a couple of coatings of "skid-no-more" on the upper and lower angles of the bend brake. I used this paint on my previous XL and it has proven to be a great product. It actually has small particles of galvanized rubber held together by the paint. It's soft, it compresses and most important... it will increase the area of contact dramatically. I can't wait to try it! I will have to wait till tomorrow for the paint to dry.
