This little gadget I came up with some years ago to de-burr cases after trimming them to length, I had injured my wrist and after surgery that repetitive motion would be very fatiguing. I wanted to adapt it to power and do it inexpensively with a minimal amount of tools, at the time I was doing a small plumbing job with plastic pipe in my basement and that is where the parts came from. It just so happens that the de-burr tool fits inside a ½ “straight connector without any modifications, it is a wedge type fit so no clamping is necessary.
I have made several of these over the years, the one pictured on the right here is not the first one, that one I used a ½ “wood dowel but this one has a ½ “aluminum shaft. I first used them in my drill press but then adapted one to a battery drill for portability. The shaft diameter can be changed to suit your needs with a minimum amount of tools. On the left are the parts needed to construct the holder, I included a ½ inch bolt that can also be used by cutting off the head.
In this photo I now have adapted one to my case lathe, I found this at a local gun show for $60, it now does the chores that I always did by hand or with my drill press. I have adapted a primer pocket uniformer, case de-burr, a chuck for misc. things such as brushes, flash hole de-burr and the Lee universal chuck for turning brass.
I hope this is useful information for anyone wishing to accomplish the same task; I will in the future post more tips and gadgets from the past and present, many thanks for looking.
Neat web pages you have. Perused a good share of them. Roe
