binding a Warmoth neck is best done as a custom order for the average person not familiar with building necks from rough materials.
if you do decide to make your own necks, know that you'll need a few specialized tools and jigs plus a significant amount of hands-on experience to get your work to look like what W turns out with every bound neck they make.
for your template work, you'll need to make a decision about when to route the binding recess (essentially a rabbit around the edge of the neck) - will you do it before or after you have radiused the fretboard/fingerboard? it certainly is easier to remove the wood prior to radiusing the fretboard/fingerboard, but you can get yourself into trouble with the depth if you are not precise in how much wood is sanded off while radiusing. if instead you remove the wood after the radius is applied, you are going to have difficulties maintaining a consistent tool angle in reference to the neck edge.
this is a great place to highlight the beauty of CNC, and how you can produce a cleaner product than is possible with hand tools and custom jigs
all the best,
