If the Core Catcher material is difficult to manually push out from the core catcher use the Arbor Press (see Figures 4 and 5). There are two different jigs that can be used to assist with the pushing. One for APC (Figure 6) and one for XCB (one for lower bit; figures 7). Lubricate the moving parts of the arbor press with Lubriplate, or a mixture of Lubriplate and Marvel Mystery Oil.
