I went to an auction recently and picked up a set of screws that
turned out to be ball screws for a 9x42 Bridgeport.
I am a little surprised about it, as, I thought, ball screws could
only be used in CNC mills whose screws were held by stepper
So, do they have use in a manual mill and are they in any way better
than regular drive screws? Or are they for CNC conversion only?
The ball screws will work great on your machine. You should install them
The ball screws will give you better turning power, and faster manual rapid
You can achieve better finishes and better accuracy. Your finished
tolerances will improve.
Your tooling will last longer, it will actually get sharper, the more it's
You stand to save considerable operating energy costs, while reducing the
motor temperature, thus extending it's life.
You'll save money on machine lubricants.
You will increase the value of your mill to the highest market value, even
if the machine isn't in very good condition.
Once installed, the ball screws will never wear out.
Install them right away, it's simple to do, and you won't feel compelled to
ask more questions about doing it. You'll be amazed at how simple it is.
Most of all, installing the ball screws will give you something better to do
than post messages about some has-been weather girl from Alaska. Or her
daughter, or grandchild, or neighbors, or boyfriend's mom, or her lawn, or
her clothes, or her vaginal dryness, or her limousine driver, housekeepers,
paper boy, pizza delivery, cable guy, pedicure girl, house painter, pet
But if you need advise on what color to paint the mill or your worktable,
everyone will be glad to help with those more advanced tough issues.
I'm all for being nice, but you are a really fuctup douchebag half the time.
Do you feel you need the attention you were deprived of earlier in life, or
Can you not exhibit a small degree of self-control?
Do you feel that you're entitled to continue this behavior because other
people do it?
Do you feel that you need to be a usenet gossip?
Why would you imagine that anyone cares that you read a news article?
The incomprehensible part is why can't you find anything else to do instead
of posting this useless drivel?
Is your mind that slow?
Do you post crap because of your lack of knowlege of the metalworking
If you read more good posts, you'd know more about metalworking, and about
Heat the garage and do some metal work.
Are you the only dude on the fucking planet that doesn't get pleasure out of
using your machines?
Are you one of those guys that gets every tool known, only to hang them up
in the garage, and never use them?
Do you have the mind of a child, that once you use a machine you're bored
Contact one of the Chicago newspapers to see if you can write a gossip
column if you want to find readers that give a shit about those nonsense
Start a gossip blog, or make opinion videos for youtube, myspace etc,
instead of what you do now.
Or you could take up knitting, don't worry, lots of manly men knit. But more
importantly, it a good hobby for gossipy twits.
You're insanely dimwitted about criticism of your senseless posts. You tend
to take a sociopathic position, like most other people that are obsessive
finatics about posting crap.
I didn't say you were wrong, just unduly harsh on someone that at least cuts
metal. Of course it bothers me greatly to see off topic trash by anyone, but
it is especially iritating by someone that doesn't know the business end of
a screwdriver. This has been one of the most successful NGs in the history
of USENET generally because it is policed relatively well by all. However
lately, contributers like Cliff are ignoring the rules and frankly ruining
this NG. These people are just off-topic trolls and should be ignored in the
hope they will go away. I had hoped that with the end of the election, he
would just fade away. Unfortunately, it hasn't happened. What are doing
reading his diatribe anyway?
