I bought an extra 12 buckets this week and needed taps for them. The only ones I can get locally are 7/16, but I keep reading about the advantages of 5/16" taps, so I knew the only solution was the stupid one! Got to make my own! With a bit of visual research of what is out there and measuring my existing 5/16 taps I was able to quickly design and prototype a decent looking tap and hook. Fortunately I have a bunch of stainless steel around, these are made from 1/2" diameter alloy 303, which is similar to 304, but easier to machine.
Anyways, I thought I would post here to show the process I used, even if it is not something that is doable by most members.
The first step was drilling the hole, I used a small production lathe for this that has a lever tailstock to easily pull the bit in and out for frequent chip clearing. I drill the bodies from each end and used a 3/16" drill.

The next step was reducing the body side to just below 3/8" to allow the hook to slide on.

And after that, using whats called a taper attachment to add the 3 degree taper to the spout. I also rounded the end over at this moment to make it smooth and easy to insert.
17802
Last step was to cut an angle into the front to make sure space didn't try to run back along the tap.

Here is my completed run
