Hello Everyone.
This Lead screw replacement MOD is a Very easy project for any one to try.
It is not the End-All-Be-All of MOD's, but for small turnings this MOD can
really help you out.And for the price? ($11.01 for a 3' acme screw.) I think
it's well worth the effort. And the really neat part is, I can go back in min.
to what My Legacy originally had. For my Legacy 200 its only two sets of
set-screws that need to be loosened upso the leadscrew can be removed. And IF I
did the same thing on my 1000ex. it would be just as simple. (the acme screw is
longer, but only two set of screws are only needed to be loosened in orderto
remove and replace this acme screw.) the split nut is easy to make, and even
easer to switch form oneto the other.Something for everyone to think about? Why
not try it ???
I plan to try to get into the shop tomorrow morning and do some more testing
on this MOD.If I do I will let everyone know more, If I cant, my next day off
is Sunday. And I promise, that I will be in the shop then. ;-)
I think, Legacy Slogan is true. "Legacy, Where your only Imitation, is your
Imagination".
Have a good night.

Hi Tim
Yes I do own a 5/8-8 Acme tap. Its the easiest part of the job. just drill a
1/2" hole on the plastic.
Then tap it, cut in half, and then sand to fit, once fitting is done just drill
a 5/16" hole and tap 3/8" for the set-screw.
Its the same process for cutting the 5/8-4. Supper EASY. ;-)

Hey Curt,
Super excited to see your results for sure. I may convert my Revo for the pen
and game call turning.
Just keep us posted on the results and any adjustments you end up doing to get
it to work.
I see no reason it will not work. Yes you will have to explain how you threaded
that split nut too. I'd assume you have a
tap like many of us do for the larger one. Except you have 8 TPI instead of the
4 TPI

Hello Everyone.
"Well" I works! ;-)
Before We go to far, Its not been fully tested yet. but it dose work on the
test that I have done today.
This morning, I started by removing my 5/8-4 Acme screw on my Legacy 200.
And replacing it with a 5/8-8 Acme screw.
Now what this is suppose to do is, It slows down the pitch by 1/2. What use
to give me 4 rev. pre inch, it now take 8 turns to cover the same distance.
So by using this idea, my smallest pitch will be being 1/2" on the chart,
it will now be 1/4". (basically what ever the chart states, it will now be 1/2
of what the chart states.)
I started off my day, by making a new slip nut for the 5/8-8 screw, (very
simple
process, We can go over the process latter if anyone likes.)
Then I cut the new Acme screw to size, turned the ends to match the original
5/8-4
Acme screw on my 200.
And then putting the hole machine back together, in the afternoon.
OVER ALL it was a very quick job to do.
NOW the reason why I did this? The Legacy was Originally made for making
furniture.
and other lathe type of work, The 4 threads per inch was prefect for large
spindles, But when
I started working on the small side of things with my 200, I found that the
pitches were just to
big. making a small rope on a Magnifying glass handle, The 1/2" pitch, did not
look right, It was
almost to large for the small spindle.
Now this idea is NOT new, But it is the first time that I have tried it. Years
back We (a number of
people in this group) tried to find a better way to make a smaller pitch so you
could get a finer/cleaner
looking cut when using the drive motor and the Legacy's gearing.
As a general rule of thumb the more cuts pre rev. the cleaner the cut.
I found this Acme screw on Mc Master Carr web page. for $11.00.
https://www.mcmaster.com/products/screws/acme-lead-screws-and-nuts/?s=acme+screws
I figured? what did I have to loose if it did not work? I still have all my
original parts and it is a easy
replacement. So I can replace it any time I choose.
Here are some photo's.
Please let my know what you think about this idea.
