If you are doing branches like I did its allot quicker to texture the round bar and cut sections then gas weld them up. I texture the welds in the forge if they fit. If you whind up with a large branch like the one on the pit it won’t fit in a small gas forge like I use. So I grind those welds with a die grinder to blend those welds. Simple bends I do before I cut sections.
If you want to taper the round bar down I square it up taper it down and re-round. For thinner branches I just grab rebar that’s laying around, round it good so you don’t see the original texture and then texture it.
I do the oak leaves by grabbing a bunch off the ground and tracing them out on flat stock. I then cut them out on a band saw which is a real pain. Then clean them up with the grinder then it’s into the forge. I use basically dull chisels made from old coil springs to do the lines. Then one last heat and bend with tongs and a smooth pair of needle noses I ground for the job. You could probably have leaves laser cut or water jet if you wanted. Its what I would do if it was for a production projects not my back yard. I weld the leave on and die grind them in as well.
The Acorns I do with 2 spring swage set up like O1tundra. One with an acorn in it and a spring swage I made to neck down the bar I am working before it goes into the acorn one.
Don’t forget to wire wheel your work before painting. Removing forge scale will also add texture to the work.
