If you scroll to the bottom of the page, you will see a raw casting for a
25" x 3" wide raw casting that you can scrape in to use as a reference
surface. At $210.00 plus S&H it seems like a logical first step for those
that want to improve your old iron.

I figure if you can't get this thing scraped in, it is better to leave your
machine alone and deal with it's inaccuracy's.
Glad to see Michael Morgan is back in business. I got one of
those castings and have made a decent straightedge out of it. I
think it is too heavy, and therefore droops onto convex or
concave surfaces more than the best Starrett or similar units,
as it weighs about twice as much. You have to have the casting
normalized after you machine off the hard shell, or else it will
continue to warp for a year.

His books are quite good, haven't seen the videos. I have,
however, seen him demonstrate the process at the 2001 or 2002
NAMES show. It is always amazing to see a real pro perform,
whether it is music, theater or hand scraping.

Be aware he had some problems delivering stuff in a reasonable
amount of time, so pay by credit card.
