DWG Addendum
48.01 Add note for drilling .420" flat bottomed holes: Take rake off drill bit. Center drill and rough with stub length drill.
48.01 Item 3) Dowel Pin -3/16" DIA. x 1" LG Qty 10 
48.02 Rear barrel plate, The .125" deep x 25 degree cutouts and the pins are *only* needed for the drum magazine, not necessary if you are only building the stick magazine.
48.04 Rifle barrel assembly. Add note: Leave liner ½" long on each end. Tin the liner on the lathe at low speed, sand 1 ½" each end.
48.05 "Face ends of spacer tube square and to length as shown on drawing". ADD: 9 1/4"
48.09 Ignore the comment about "two different length side brackets". They are the same length.
48.09 Centerline shown in left side view is wrong. The long arm of the left side rail needs to be *above* the centerline.
48.09 Rear view. The reamed .250" hole, .015" oversize, can go to .375" for easier assembly.
48.13 Cocking switch knob, .250" thru hole does not need to be reamed.
48.20 Recoil pin, the .156" dimension should be .100"
48.21 Note B , the .093" hole is the one inside the extractor slot.
48.30 Part number for best fit woodruff key cutter: Rutland 7299-2025
48.30 Extractor, detail E, add note: Install in magazine to drill hole in correct place.
52.00 Add note: The base plate bolts to the elevating plate, so the 4 holes in the square pattern need to line up. The holes in the base plate are shown 45 degrees out of true position
53.00 Part C, the ½" -32 thread is not correct, it should be 5/8" - 32.
  Loctite 609 is a very good bonding agent for installing 5/16" dia. liners in any kind of 22 RF barrel.
