Hi THere,
I've been working opn a wood project like the one you mentioned, but I was trying for a padded free-sparring version. Though I don't know what it is you're going to use it for, I'll give you a run-down on my plans:
I started with a 1/2" piece of plywood and fashioned it into a rough circle (this turned out to be a pain, so it's where I'm stuck. Nonetheless....)
Use some kind of thick foam as a boss, allowing for incidiental contact to be safe, and some light punching with the buckler face, without killing someone. Landau's my first choice.
Then, I was using a plastic handle from a masonry tool that I removed from the tool. It basically was a piece of light wood with this hanbdle screwed onto it. I undid the screws and I'm going to replace them with longer ones of the same gauge.
I have no idea if this attachment design is historical, but it does allow usually enough clearance for the hand to use the buckler in a single-fisted grip. It's also cheap and easy to find; just make sure you buy the types with the screw attachment to the tool rather than with the welded or riveted attachments.
Then, my plan is to foam the back with foam rubber and the edges with Landau. Voila.
I've done most of these steps on other, older projects before I got seriously into WMA. But at least that's a quick, cheap approach requiring to access to metalworking tools. Of courtse, if oyu're looking for a non-padded sparring buckler, then that's probably not what you want, but hey, I tried.
