Select Materials
I used 25mm alloy hex
Could use 16-25mm hex. Brass would also be fine
Face Cutting and Center Drilling
Holding the hex in the lathe center drill and face cut
Drill the hole out to 12mm and 25mm deep (for the 1/4 BSP tap) on one end.
Drill the other end out to 9mm and 15mm deep tap out to (10mm)
Tapping
I held the tap with the tailstock in the lathe to start the thread. I find this is a good way to get he tap the start straight. Some taps have a center hole which is easy to use a live center to hold the tap, others I just take out the center and use the shaft to hold the tap straight.
Cutting the Slot and Polishing
I cut a slot a third of the way down at an angle of @30 degrees and went down half way with a hacksaw. I cut down until I went half way through the hole. Less will give you an angle less than 180 degrees more will give an angle greater than 180 degrees. Once it is completed I polished it on the buff to make it look good and give it a better finish.
Stand
I threaded a rod and fitted it into the 10mm threaded end sharpened the other end pushed it into the ground for a stand. Any stand to hold it up would be fine
