To counteract the slow rotation of the toolpost while doing cutoffs, a
machined a 1018 steel plate to go between the 5914 tool post slide (on
the cross slide) and the Dickson toolpost. The plate has a ridge on the
bottom, the ridge being a slip fit into the T-slot on the cross slide,
and two holes. One hole is clearance for the 5/18-18 rod that bolts the
toolpost to the cross slide, the other accepting the anti-rotation index
pin.

I've never seen what this toolpost is supposed to look like, and to
include, and have been guessing. Can you suggest a URL that leads to a
good photo or two? Thanks.

Some pics here in the Harrison section, maybe the best on this page
http://www.lathes.co.uk/harrison%2Dm/page7.html.

This seems to have a big acorn nut atop the threaded clamp rod.


My Dickson has a M12
threaded post IIRC and a 19mm hex nut on top which bears on a heavy
collar then onto the toolpost see on this page
http://www.metal-arts.co.uk/jacks/index.html, I think that is standard
for the machine.

And this one has a collar and big nut, which is what mine came with.

I think that the collar I have actually belongs between toolpost and
ridged plate, and that the top collar is missing. Although they could
be identical. The collar I have is beat up and may be slightly oversize
for the top position, and interferes with the wrench at some some holder
clamp positions. I just made a new bottom collar, the first part made
by me with that lathe. Perhaps the better location afforded by this
collar will resolve the interference problem. If not, I'll make a new
top collar, or a big acorn nut.

Thanks for the URLs.
