4.4 Loading Samples
The Bone-Cutter is designed to cut 7.5” wide weld samples, any material wider than that
could damage the blade and/or the cutting levers ram. When loading your sample strip,
ensure that the lengthwise edge is flush up against the sample strip guide (See Figure 4.2).
Once the sample is loaded correctly, pull the ram lever down in one swift motion allowing
for a clean and easy cut. If cutting extrusion welded samples, load the sample with the
extrusion bead closest to the Bone-Cutters’ pivot point (See Figure 4.2).
The Bone-Cutter chamber can hold up to ten cut bones at a time, when removing bones
ensure the ram lever is propped in the upward position.

4.5 Blade Adjustment
a. To adjust the blade width, first remove the 6 screws that hold the cover to the main body
using a 4mm Hex T-handle (See Item 2, Figure 4.3) and remove the cover (Item 3, Figure
4.3). Use a 5/8” open-ended wrench to tighten or loosen the blade standoff (See Item 1,
Figure 4.3). This adjustment tightens the contact interface between the ram and blades. If
a cut does not feel clean or feels like it is taking more effort than it should be then most
likely a blade adjustment is necessary.
