You might have to cut and paste to get it to work. Scroll to the bottom
of the page and you will find the adjustable reamers. These guys are
quick on shipping. There have been times that I have ordered things in
the afternoon and had them show up in the morning UPS delivery.

If the blocks are very thick, a .002" oversize hole is pretty tight.
You will have to make doubly sure that everything is in perfect
alignment so that there is no binding of the tube.
