Loved Espeefan's tutorial so much, I made my own jig. I made small change to the original design by adding a small oversize lip at the bottom to act as a stopper, when hammering metal.
Here are results of my "fender making"
Made holding brackets out of brass
Polished the fenders and attached to the brackets with Automotive goop....
It is stronger then it seems and no holes on the fenders.
