Know what preserve jars are? lockable top ones like grandma pickled stuff in,
made all that great jam and stuff...anyway, clear Thompson's
Water Seal, or colored variations if you are brave, warm it up in the jar, in a
double boiler set-up, till it's really hot... put the bone handle section in,
and seal it.
Put it on a shelf for a month or two, longer if you want, you can let them sit
for quite a while if need be, or not in a rush. When
you take it out to use it, warm it in an oven at around 150f to dry it out, and
let it cool slow in the oven. 15 to 30 min ought to do
it.
or...
Rig up a way to put a container in some kind of set-up that will allow you to
pull 12 or 15 inches of vacuum... put the bone in the Thompson's,
seal the rig and pull a vacuum
for 15 minutes, let it off for 15, and repeat the cycle three or four times,
then do the same dry-out routine.
Lazy in-a-hurry time-is-everything method. Soak it in
acetone for 5 or 10 minutes, then massage a good 24 hour epoxy into all surfaces
with your fingers, wearing surgical gloves... after it sets you can rub it down
a bit with superfine steel wool or 600-800 grit paper with water, and polish it.

From Ben Parker some tips for pouring babbit bearings on a
power hammer.
I poured the outboard rear bearing this past week end. I was told that the
Little Giant folks were selling something to make a dam to prevent the hot
babbit from running every where. I think I mentioned it - they call it "Dam It".
I remembered something like the description that was given to me and I found the
stuff in the electrical section at the Lowes Store. It is used to seal
electrical conduit that you don't want small critters or water getting into the
ends of the conduit. It is cheep and doesn't loose its sticky properties at the
600 or 800 degrees the babbit gets to. It is called "Duct Seal" and sells for
about $1.50 a pound. I made a thin roap about 1/4 inch in diameter and place it
to form a dam where the open end of the bearing housing exists over the shaft
and across the top of the shim stock that will prevent the babbit from running
down into that area of the bearing. Works great just a little messy to clean up
but better than problems I have had with the old juke fibers the plumbers use.
I also figured out how to tell when the babbit is hot enough to flow properly. I
use an old candle to flux the metal. I use a small chunk about the size of a
black eyed pea and pitch into the melting pot. When the wax melts and almost
instantly flashes to a flame (actually pops just a little) then the babbit is
hot. If the wax melts and smokes before it flashes then it isn't hot enough yet.
A very handy bench for a tight space, it is at the right
height for working up close on objects. It was constructed from 1 sheet of 1/2
in plywood and 2 2x4x8. The bench top is 3x1 ft. and is mounted to a box that
has been screwed to the bench. Split the 2x4's to make internal support members.
The legs were split from 2x4 and hinge mounted.
