Does anyone know where I can source bone (or synthetic) rod for making 5th string nuts? I have a few shaped nuts left from my last purchase from Elderly and have some from Aliexpress. However the Aliexpress ones are somewhat thinner than the bone ones.

Stewmac has them, relatively expensive. They are also sold by a lot of vendors on ebay, and through Amazon for less. Maybe you can find someone local selling them in New Zealand on one of these two vendor outlets.

These are fun to make from beef soup bone.

How would that be done? With an annular /hollow drill bit (if there is such a thing?)

First, you have to boil all the fat and gristle off the bone. Dry it out. Hacksaw a 1/4 or 3/8 inch wide piece. Flatten 2 adjacent sides on 80 grit sandpaper glued to a flat board. Cut or file to form a square cross section. Chuck it in a drill . Hold a file to it to round one section off until it is about 1/8 inch in diameter.Cut above this rounded section to leave a cube on top of the rod. Chuck the rod end in a drill and file the cube into a dome. Send me a private message if you would like a diagram of the steps.

An electric drill like Lapsteel described will work pretty good but I'd prefer 120 sandpaper over a file. One way or another, do be sure to wear a decent dustmask. Heads up: bone smells real bad when friction heats it up!

I use the drill method too, but with a belt sander running instead of a stationary file or sandpaper. Having the sander running too speeds it up a lot. I get my blanks for this from cutting down oversize nut blanks to fit the necks.

While searching online for suppliers I came across a listing for bone rod from Luthier supplys (Depaule). However, my antivirus prevents me from accessing their site. I managed to finally access it through one of my phone browsers. One time I hit the site but is said it was under construction. I can access Depaule Supply but cannot find the item I want.

I've made these from deer antler also. It's not as hard as bone but I couldn't tell much difference in sound compared with bone. A file and drill press works great either way.

I picked up a few of these and they are really great.  However, 4mm is pretty thick for a 5th string pip.  I have to thin these down.

I posted on FB and one of the responses was bone knitting needles. That suggestion is sending me off on a totally different tangent of search.

The last time this was asked, I posted a link to Delrin (acetal copolymer) rods. Besides being quite hard, Delrin is somewhat slippery making the slots resistant to wear. Available in many colors including off-white and black. Its durability makes it useful as a bearing, also. 

This UK supplier sells them in 3000mm length (nearly 10') but there are other sources.

Like lapsteel and Bart, I used a drill. However, for shaping, I used a cutting wheel on my Dremel tool and did it outside.
