LEZ COUNTERBORE 5/8 INCH WITH PILOT
This 5/8" diameter boring tool, has 1/4" diameter pilot. A 10" thread extension is used for boring holes in hard-to-reach places. Primary use is in the installation of the landing gear on the LongEZ and Cozy aircraft. 3/4" bore does not have 1/4" pilot and must use the pilot received with the 5/8" boring tool.
I am stocking up on sharp cutters and bits and whatnot in preparation for my Cozy MkIV build. As usual, the Aircraft Spruce search and purchase experience is good, and the products are excellent:
This is a very important tool if you are working on a Long-EZ or Cozy. The reason I gave this three stars is the machining was not complete on the pilot. The pilot shaft is supposed to have two flats on it for the counter bore set screws. This particular pilot only had one flat and had to have another flat machined on it before it could be used.
Yes, the pilot is removable on part number 12-00219.
