I shaped it with a hack saw and a tiger wheel(flap pad) on the grinder.
Ummm? yes I am going for just that. however, the angle of the knee dent area kinda slopes towards the center of the bike and I can just make one and flip it. I wish I could. I have an educated guess and will see if it works but if not I will try try again.
Oh for reference.....I would use the green high expanding foam can. It is a little more dense , doesnt have swiss cheese holes and doesnt get a void in it as easily.
