make your own. Get a good crosscut file, cut it in half or the desired lenght. Then weld on a thicker screwdriver where the shaft has been bent.
X2. I made mine from a short leaf. I have a couple, but that one is my most used. I like having a little weight behind the *******. Less work, no hammer marks.
X3 on the ******* made with a leaf spring but not completely smooth. I like to run the contact face on a belt sander with 80 grit long ways. The scratches aren't rough enough to mark the sheet metal but mark it enough to help with tracking so you can see where you are hitting easier. Posted using the Full Custom H.A.M.B. App!
I use both smooth and the file type. For a beginner, it is much easier to use the file type, as you can see your progress very clearly. It also seems to work faster. You can get file types from Eastwood, and I see them on Ebay all the time. The smooth *******, you can get from Tinman Tech, Dagger Tool, and others, or make your own, as others suggest.
I'm going to make my first one out of a large cross cut file and later make a smooth one out of a leaf spring. I tried using the large file I have with a dolly as an experiment on my 48 Plymouth and was thrilled with the results on one bad dent below the back window. If you have not tried this method give a shot as it's cool.
