Bob,

1) Sounds like a workable solution to me

2) I don't have a No. 67 (open throat MF router plane) but do have a No. 77
(closed throat MF router plane).  I just used a thread gauge on it and confirmed
with a die on the post that mine is 1/4-28.  I guess MF standardized on common
threads more than Stanley at least for router planes.

Rountuits keep arriving, from whence I know not.

Got out my MF #67 router plane for a good clean up.  There's a bit of oxidation
and some crud.  I can deal with both, but I ran into something that I need help
with.

There is an upright threaded rod which has depth adjustment thumbscrew an a
thumbscrew that holds the holding bracket that fixes the blade in place.  I
would like to remove this threaded rod to assure full cleaning and rust removal
on all parts of the thread.  I don't have a thread gauge at hand; so I can't
determine the number of threads per inch.  My search fu remains weak.  I have
not found a web page that provides that information. My plan is to put 2 nuts of
the proper threading on the post, lock them together and remove the post.

1)  Is my approach OK or is there a better way to do this?

2)  Does anyone know the thread pitch for the MF #67, or a URL where I can find
that datum?

Thanks in advance.
