Our Panel Beating Bags and mallets have been a staple in our product line for years and it's one of the first things you should buy when starting the road down metal shaping and fabricating greatness. The basic concept behind using the mallets and sandbag is fairly simple, but learning to strike the metal at the right location and how hard is something that takes a lot of practice. One thing you need to do when using the bag is to make sure you're comfortable and have a good base to use the bag on. Hammering on the bag takes a lot of force and you need plenty of space all around you to swing the hammer and move the part in all directions. I decided to make a panel beating station from salvaged materials so I could stop moving my sandbag all over the shop and trying to find a good surface to use it on.
