1. A saw guide for a saw arbor guide assembly with an arbor, a plurality of saw blades rotating about the arbor, and a guide post, the saw guide comprising:
a head adapted to attach to the guide post, wherein the head comprises one or more intake channels adapted to supply lubricant to the saw guide;
a body connected to the head, wherein the body is located between adjacent ones of the plurality of saw blades, the body comprising:
first and second faces;
a plurality of lubricant openings located on both of the first and second faces for supplying the lubricant to the adjacent ones of the plurality of saw blades; and
a plurality of fastener openings located on both of the first and second faces, each of the plurality of lubricant openings spaced apart from all of the plurality of fastener openings;
two pads, wherein a first one of the two pads is attached to the first face, and wherein a second one of the two pads is attached to the second face, each of the two pads comprising:
a plurality of cut-out regions, wherein each of the plurality of cut-out regions is aligned with, and partially surrounds, one of the plurality of lubricant openings to expose a portion of the first or second faces around the one of the plurality of lubricant openings; and
a plurality of pad openings, each of the plurality of pad openings aligned with one of the plurality of fastener openings;
a plurality of pad fasteners, wherein each of the plurality of pad fasteners is adapted to extend through one of the plurality of pad openings and one of the plurality of fastener openings;
one or more passages extending from the one or more intake channels and extending through the head and the body, wherein the one or more passages are configured to carry the lubricant from the one or more intake channels, wherein each of the plurality of lubricant openings is connected with one of the one or more passages, and wherein each of the plurality of fastener openings is unconnected with any of the one or more passages; and
for each of the plurality of lubricant openings, a flow control valve located in the one of the one or more passages proximate to the lubricant opening to control a flow of the lubricant through the lubricant opening;
wherein the flow control valves are configured to differentially control the flow of the lubricant to different ones of the plurality of lubricant openings.
