Default Nelson Lawn Sprinkler Repair

I found two of these at the scrap yard. They both have plastic cams that are broken.

The red piece is the broken cam that has been glued together. I used it to extract data and as a template. I scratched some numbers on the paper and I'm ready for the machine.

I used 1/2" thick aluminum and milled it to .285" thickness. Then I drilled the 3/16" attaching hole. This hole is reference for locating the other features and for locating as a template later.

I applied layout ink on the surface and placed two pins through the workpiece and the part. I then scribed the trim line.

Back on to the mill to reduce the thickness. Notice I have left the material near the trim line so it is still visible.

Here I am adding a square counterbore using a 1/16" diameter end mill cutter. This small cutter will give me the small corner radius I desire. Before I trim out the pieces I must check the fit on the sprinkler. Securing these parts in the machine vise will be much simpler with the block intact and a straight reference edge to locate and provid orientation.

Where is the fun in that? I think the challenge is “ can I make this part in my own shop?” No matter how much time it takes, the payoff is in the challenge of it.
