This jig is now ready for sale.
If you have 16D cans with broken holding tabs this is a convenient easy and accurate way to drill holes to use screws.
It includes Allen wrench to clamp motor in place.
Also includes center drill with depth stop to set depth correct every time.
I have nine ready to ship at $40 plus shipping. Prefer shipping to the lower 48.
I will honor the four folks from the original post. If you PM me we can exchange details.

Happy Thanksgiving to all.
