Hi Chris,

Your techniques is a total unknown to me.  How do you do your method/s?  I
can use my
imagination but...it could be quite wrong of course.  It "sounds" like a
horizontal tumbler
action of sorts.

I presume; the copper rod (one closed end) is rotated by the outside chuck
slow drill , with the carbide and diamond paste
tumble therein?

I presume the "U" copper is stationary and the slow steel (?) drill rod
simply rotates the carbide rod laid
atop it; while the diamond paste "slurry" works?

Why just the medium grit?  What is the medium grit?

Would a drill press holding a portion of the carbide and a suitable
cloth/pad with the diamond paste thereon work abit faster
for the "selective" portion of the carbide rod used?

It seems like it is kind of a "art".

Take care, Meredith

This diamond grit material will likely cost alot more than the carbide rod/s.  Theres probably many others around with cheaper or better material.




Hi Meredith,



       Strangely enough diamond paste is not very expensive. I pay $10 for a syringe. You use a medium grade, not a fine grade. Titan products seem to be overpriced.

       You can use a copper tube to polish a Tungsten Carbide rod, OK. This takes quite a while by hand, but using a slow drill to hold the rod is quite practicable. Alternatively, wrap a strip of Cu sheet in a U around a suitable drill shank.
