I needed to get a slapper for my panelbeating efforts.
Many homemade ones are made from an old automotive leafspring. But I didn't have any laying around.
I found these pry bars at my local HF store on sale for 1.99 each. Today the regular price is 3.99.
Using a cutoff disc on my angle grinder I cut them on the red lines in the photo.
Then I overlapped them a little and mig welded them together. I thought overlap might be stronger since I was welding tempered steel and wanted to minimize the chance of the weld cracking. I will try butt welding the two pieces together if there is a next time.
Ground the striking surface smooth and polished it a bit with my sander with some aluminum oxide grit.
Found some plastic tubing to use as a handle, and Bobs your uncle! Works a treat. After trying it out, I immediately regretted not doing it sooner.
