[sdiy] Tubular Bells

[James Patchell]

That calculator looks useful, but, for some odd reason, that web page locks 
up on my computer.  I tried Mozilla, Internet Exploder, and Firefox and get 
the same result.

I would agree with the Electrical Conduit assement.  It just doesn't seem 
to work very good.  That also may have to do with the way it is made.  It 
is made by taking a thin sheet of steel and rolling it into a tube.

Thanks for the links, I did not stumble across either one.

It is, from what I have learned so far, looking more like I should try and 
get a set of bells that are already made...somehow...still, I will keep 
looking.
