The steps I have here came from Create in Japan back when Orion was their US
distributor.
They are made of rebar, about 3/4" and welded to a bracket and also a
muffler clamp. All galvanized after welding. The roughness of the rebar and
galvanize makes for a secure foot and hand hold. I only bought 4 and made 2
more out of steel (instead of aluminum) angle iron as mentioned by Mark. I
guess I'll make up a few more and give it a try and not a fly!
And I used 1 7/8" HD muffler clamps. I bought a whole bunch of clamps from 1
1/4 to 3" directly from Dorman some years ago when I first started building
the W2PV yagis. Had a few others chip in to meet the minimum order. Price
was about 1/3 what the auto stores wanted.
Glad to know I'm not the only nut on here.
