Needing a simple way to fix vintage 16D motors that have had there bent-over tabs broken off or weakened to become non effective. 

Larry and I put our heads together and came up with this jig.

This is a jig to drill an accurate pilot hole in a 16D can and end-bell together. 

There will be in center drill that drills a pilot hole to accept a common self tapping screw.

The center drill supplied,will come with a depth stop to be set to avoid drilling too deep.(see pic) 

This is a picture of the prototype. We plan to order 10 or 20 depending on the interest.

Let me know If you have any questions.

I might add that the shots above show a brass sleeve slipped into the 1/8" guide hole with a 1/16" rod passing through the can to verify the 26 degree angle of the Parma 16D can inside the jig (Pro-Slot Speedy FX motors use the same angle). Those are not part of the jig ... just a bit of quality assurance on my part.

 

One other detail not seen is that there is a clamping screw between the buttresses on the base to hold the can firmly in the jig.

This is a neat tool that will come in handy. I could have used something like this back in the '70s when I drilled Champion C-can clearance holes for mounting to Mura endbells. My Unimat came in handy back then.
