R-R PIII - Liner extractor A particularly unattractive device.  The cap is made from a 3" deep section of 4" ID tube with 0.25" wall thickness to which is welded a 0.375" thick end plate.  The base plate is also 0.375" thick and is turned to .040" smaller diameter than the bottom OD of the liner; the upper face is stepped to locate the plate inside the liner.   Whitworth threaded rod of 5/8" is used to draw the two elements together.
