Well done, a nice simple solution that should work well for not a lot invested. The nice thing is it will work with any caliber either rifle or pistol. Great example of the KISS principle in action.Here are photos of the shaker in its final stage. I opted not to use the timer. Easier to just count down mentally. The difference in the outcome based on time is minimal. I get about 15% reduction in powder volume after ten second or 15 seconds or 20 seconds. Doesn't seem to matter above ten seconds.
First photo is of the inside of the box. The circuit card controls speed. I still have to work out best speed.
Second photo is of a shell holder placed on top of the shaker box. I will fill up to 50 cases and place them in the shell holder. Then start the vibrating.
Third photo is of the shell cover in place over the shell holder. I will place the shell holder with shelled filled with powder on the top of the box. Hold them in place with the white cover. Turn on the shaker for the proper amount of time. Turn off the shaker. Examine the cases for good volume reduction.
e' finito.
