Steel pipe isn't precise in size and definitely isn't guaranteed to be
round, as you'll find out when you try turning it in a lathe. Brass
pipe is much closer. The pipe I've bought recently from HD and Lowes
does machine and weld nicely.
*Yes. My RedNeck lathe v3.0 has not done a good job so far I am sad to say
:-) BTW do not ask - one day I might muster sufficient courage to tell.
I have got a pair of superb little 1" pillow blocks cheap. I found a 9"
pulley to match from scrap - cleaned up nicely. However, taking 1mm off the
pipe diameter - priceless.
Still, I have solved minor intellectual puzzles (which I am sure you guys
would have done on a sub-tentorial basis), such as finding a centre on a
mounted endcap (sadly, the bolt through the centre will not turn the pipe in
a true concentric fashion even with a liberal use of hammer). On the other
end of the pipe I fashioned a decent red neck 4-jaw chuck with four 10-32
screws. Much better result.
I was thinking of a floor flange in lieu of a face plate, however the way
they fit together with the pipe I would have to take a whopping 3 mm off the
flange thickness to make it run true.
I might cut a 1"-8 thread in one end of the pipe instead - that would have
all sorts of other benefits.
BTW the local machine shop quoted me $45 for the job...
