My way of making chainsaw Damascus is a bit different from anything I have seen. So I thought I would share my method here and see what you guys have to say.
Set up:
I start with a 7/16 rod of 4130 chrome molly and several chainsaw chains. I take the chains and cut one link in each. I now have strait chains, I place one on edge (bar laying flat and chainsaw teeth up) at 90° from the end of the rod and weld it in place with a tig welder and 4130 wire. I then proceed to wrap the chain (teeth up) around the 4130 rod. Where this chain ends I weld the next chain and continue the wrap until all three chains are in place.
1st chain
Welding:
First I take a 2 gallon bucket of hot water and ad 3 cups of 20 mule team borax I proceed to heat the billet several times to near weld heat and quench in this borax and water mix. I do this no less than 3 times as a cleanup of the billet. I then bring it to cherry red and flux well with borax, reheat to welding heat and pound it square on the anvil. I reflux and reheat then start working all four sides on the power hammer.
before folding or twisting
I like to draw out and fold this billet 4 times, then twist and fold again. This process creates a rather unique pattern that I have not seen elsewhere. I will post a finished blade shortly.
