Room for everybody was Re: Threaded Rod WORKS!

Ballendo,
The original post was asking if threaded rod would
be ok for wood working. Then all kinds of answers came. It
is obvious to me only a few people read the posts. Making
a wooden sign using a machine that has threaded rod would
turn out the same product as a more expensive machine. The
proof is in the internet. There are two large sites devoted
to homemade machines. How many people have taken an anti-backlash
nut put it on standard threaded rod and measured the error. What
is it? There are alot of craft people out there that are jumping
into CNC. Their suff looks great even with a .006 error. Anybody who
is anybody in CNC started off building their own machine. John told
me he is getting swamped with orders. He has opened up the CNC door
for me and others. I was milling boards for a local company using one
of John's designs. The company just had a big layoff. So much for my
egg money. Go back and read the posts on threaded rod, then read the
orignal.
