Ken, Wilf, is talking about extending the dowel out 28", see what
loading the dowel breaks under now. This will prevent Wilf from falling
off his workbench, and you seemed more inclined to do this sort of
stuff! I mean testing, not falling off your bench! TnT

I'm with you on this Tink -- as far as a 275 pound guy is concerned.
The question is, as you point out, what happens when the dowel is
extended out 28" and approx 50 pounds is placed essentially at the 14"
mark (although, what with twisting and turning, the full 50 pounds
could, momentarily anyway, be way out there at the 28" mark)?

Tink, you mentioned that you're an electrician: do you think 50 pounds
could bend the larger diameter conduit?

Cheers,
Wilf
