If you made a wooden base, couldn't you mill out a groove and just put a large piece of pipe in there? glue it if you really want to....
Let's see if I can ascii draft this here:
The view is a cross-section, the hexagonal shape representing the pipe, the saddle being the wooden base. Throw a few coats of varnish on the wood for water resistance and I think it may work. There shouldn't be issues with the board touching the base given a large enough diameter pipe and the fact that you'd be falling off by then anyways. Plus you could round off the edges of top of the wooden base structure.
Sound idea? or am I way off my rocker?
ok had to edit, ignore the dots...for some reason the forum didn't like my formatting.
If you can't understand what I "drew" I can try to get a gif or jpeg up.
edit again...i see this idea has already been mentioned....
Would scrapyards be a good place to find rails? Or dumpsters behind machine shops?
