Armstrong No. 76 Precision Back Guage

Item #: 7601

No. 76 Armstrong Precision Back Gauge offers important advantages to make sure the back is uniformly longer than the cutting edge for the entire length of the saw.  It is designed to quickly and accurately detect small variations which cause oscillation of the saw on the band wheels.   The result is a saw that will perform at its best, take the maximum amount of feed and perform predictably at the saw sharpener.

This back gauge is designed to be mounted on the top of the saw itself, which proves more convenient for most saw filers.   This "top-of-saw" model is standard and will be supplied unless otherwise requested.  For those who prefer the back gauge to rest on the leveling block, a "top-of-block" model is also available as an option at no extra cost.  Available in both 36" and 48" lengths and with both decimal (standard) and metric (option) indicators.  And as with all precision tools, the No. 76 Back gauge should be calibrated with a master straight edge each time it is used.  Straight Edges are available for sale and can be re-ground if their condition is unknown.

36” Gauge item number 7601-C36.

48” Gauge item Number 7601-C48

Lightweight, Easy to Handle -The majority of parts are made of high strength aluminum alloy for light weight and durability.

Accurate and Easy to Read - The dial indicator is rugged and converts any variations on the back of the saw into thousandths of an inch.  Markings are distinct and clear.   The gauge can be set for any crown, or straight back, as desired.  A metric is available upon request.

Greater Sensitivity - Made possible by precision ball type bushings.

Fits all Saws - The wear shoes are quickly adjusted to fit all gauges of saws - including single cut, double cut and sliver tooth saws.

Less Repair Costs - Each wear shoe has four wearing surfaces for years of service before replacements are needed.

Easy Conversion - Provisions have been made to permit the operator to quickly switch the gauge of to either top-of-saw or top-of-block operation as desired, with no additional parts needed.
