Re: Threaded Rod WORKS!

Bob,

Excellent post.

I've mentioned before that the single fastest way to frustration is
to over-spec your needs out of ignorance. It's like thinking a fancy
tennis racquet will make you play like Sampras, or a new set of clubs
will make you shoot like Tiger...

Jobshops for years have been offering +/- .005" on location as std.
tolerance; yet we see newbies who expect their little aluminum bolt
together will be capable of holding .0001 (usually because they think
resolution IS accuracy).

Build what you can. Accept what it can do. Use it to make something
better. This process of iterative incremental approximation works!
For square roots to machines...

Hope this helps.
