This is a gauge I made in haste to use for setting the height of my table saw
blade. Since I have made the gauge
I have found many more uses for it. I have found the tool to be easier to get accurate
readings because of the broad
base on the sliding portion of the tool. Most depth gauge plans call for a very
small area that will make contact with the blades or router bits. Utilizing a
larger contact surface on the slide of the tool does not allow as much room for
error when trying to judge the exact location to set the gauge to contact a saw
blade at it's highest arc when setting the blade height on a table saw.
This simple tool can be used to measure the height of saw
blade or router bit.
Other uses include measuring the distance from the outside
edge of a router bit to the router fence. It can be used to measure
depths of rabbets or thickness' of material and can also be used to transfer
layout lines.
The slide protrudes from the top of the base the same distance as the height of
the blade or bit that is being tested which makes it easy to use a scale the measure
heights or depths.
As I said above, I was in a rush when I designed this gauge. Not much for
thought went into it.
Because it has become a tool that I have come to depend on daily, I will soon be
taking the time to refine it.
Some of the refinements will include
1. The tightening knob will be on the front side instead of the back.
2. The back block could be a 1/4 to 1/2 inch thicker to make it more stable when
raising a blade or bit against the slide.
3. Add a self adhesive scale for accurate increments.
