8171/3/7 Giant Calipers
These Calipers have a maple frame with a dial indicator mounted at the opening to the throat to measure the thickness of a soundboard and similar applications. The construction allows one to measure behind ribs and bridges, if the throat depth permits. The hand held model has a throat depth of 9”. The bench mounted model has a throat depth of 16”. If it is used hand held, it distorts the measurement due to the weight of the tool. However, in the convertible model a brace can be screwed on to limit the throat depth to 9” and stiffening the frame.
Not always in stock - made to order, allow extra time.

8175 Dial Indicator
This dial indicator is used in our Giant Calipers, 0”-1” in .001” increments. Use it to make your own giant caliper. Not every dial indicator works well for this purpose. Color of face is black or white, depending on availability.

8176 Dial Indicator Stand
with magnetic base. When the dial indicator above is mounted in the stand, it can be used to measure blade run out on a table saw, blade alignment on a jointer etc, and as depth gauge.
