Brody-
The only pipe hawks on that page sure look like they were cast by the same foundry that does Davis' wares. ??
As I mentioned earlier, I just haven't had time to work on my hawk, or really any of the many projects I have started out in the shop. So, I haven't gotten serious about finding a heat treater yet. Never heard back from Mr. Oates; I (or anyone that wants to of course) should probably just call him one of these days. I still may end up trying to heat treat it myself. Just rig up a heat source to get the thing hot enough, check it to see when a magnet dangling from a wire is no longer attracted to the hot steel, go just a little more, and quench in oil and temper with a torch.
