CLEANING AND WAY SMOOTHING:
Part two, continued from part one, DISASSEMBLY:
http://crevicereamer.com/Page_7.html

MATERIALS NEEDED:

1) One pint kerosene and a small paint brush. Kerosene can be found in a pump at many gas stations. About a tenth of a gallon is enough. At $3 per gallon, that's about 30 cents. Take a wide mouth plastic container with a good sealing cap.
2) Roll of paper towels or rags.
3) 180 grit wet or dry sandpaper or emery cloth..
4) G96 Gun Treatment. This is an anti-corrosion coating. After you have cleaned down to bare metal--IT CAN RUST IMMEDIATELY. You have to protect it after cleaning and smoothing.

1) Lay out the parts outside or in a well ventilated room. For this step you need a small bottle of Kerosene,
a small brush, and paper towels or rags:
Photobucket

2) Lavishly brush the Kerosene onto all parts.Photobucket

3) Do not miss any nooks or crannies. Continue until all parts are coated with Kerosene,
Photobucket

4) While coating all parts, the parts you started with have been soaking. Go back to first parts and easily
wipe off the kerosene and wax.

Here is the cleaned part. Now repeat this procedure on all parts.

PART 3, SMOOTHING WAYS and DOVETAILS:

This is the sandpaper that I used:
Photobucket

FIRST, you will want a perfectly flat surface to lay the sandpaper on. If you have a granite surface
plate then great. If not then you can use a pane of glass laid on a flat surface like carpet.. The first
thing you will want to do is smooth all sides of each gib strip. The operative word is SMOOTH. All you
want to accomplish is to smooth the grooves and gouges a little--YOU MUST NOT REMOVE THE GROOVES
COMPLETELY. That roughness is there to hold oil. The DOVETAILS may alredy BE smooth. If so, then
DO NOT sand the dovetails. If you DO sand the dovetails, use a worn part of the sandpaper for finer grit.

You will want to keep a solid, even pressure and stroke. You don't want to create high or low
spots on either the gibs or the ways/dovetails.

Sand the gibs smooth and flat. Now you will use the flat gibs as proper shape sanding blocks to sand
and smooth the dovetails and ways. Notice the deep grooves in this picture:

Using the gib as a sanding block I am sanding the way surface here:

Notice: The grooves are diminished and smoothed--NOT GONE:

Here, with the gib properly aligned to the dovetail, I am smoothing the dovetail:

Smooth all sides:

There's a gib under there as I sand the top of the dovetail.

Again, make sure the gib is aligned properly with dovetail:

For large flat surfaces, you can use TWO gib strips:

After all surfaces are smooth, wipe and blow out all of the cast iron dust--WEAR A MASK
BREATHING CAST IRON DUST IS HARMFUL:

Now for a good coating of G96 on all of the bare metal for corrosion protection:

That's it. Now you can either reassemble in reverse order or begin your CNC conversion.

Was all the smoothing worth it? I think so. Here's the Y axis moving over 200 IPM with stock screw:
