K&S is a company that puts out structural pieces for hobbyist type people. At
least one of some of there products are. Either way they put out a series of
music wires, brass wires, rods, sheets etc... The music wire is somewhat
tempered (not annealed) but I think it is first case hardened due to a test
fracture I caused in a piece. It can be very tough to bend so I usually hit it
with a torch to anneal it a bit. This should have more than enough strength for
walker legs and other structural purposes.
To find it go to the local hobby store. The stores that sell things for the
model train and R/C enthusiasts alost always have the products. I used the
3/32" for a single motor walker. Make sure you have a hacksaw, or really strong
cutters for it. File the ends.
Good luck, thanks for comming, drive safely, you don't have to go home but you
can't stay here.
