I've just ordered a piece of 1/8" thick, annealed 4130 steel, for a tail wheel horn which will allow for varying the moment arm and steering sensitivity. Does anyone have the knowledge to suggest appropriate heat treating (time, temperatures, technique) after I've drilled my holes and shaped it?

Once you look at the table you'll probably stop right there unless you have a furnace suitable for reaching the required temperature. You can't do this in your kitchen. Be sure to note the discussion on page 15-21 in the paragraph immediately above the section titled "Tempering" regarding the importance of controlling both time and temperature. Unless you are experienced at heat treatment (and I suspect that if you were you would not be asking how to do it) you will be much better off finding a local heat treat shop to do the job for you. In SoCal we can get one small part heat treated for less than US$100.
