The “Back Story” of this Saw Frame 

Several years ago, Lee Marshall developed the Precision Saw Guide 2 for making blanking dies. Cynthia 

Eid found that she 

really

 enjoyed the saw that was developed for this system, because of the blade tensioning 

mechanism.  She started using this saw for 

all

 of her sawing, and she kept telling Lee that he needed to 

develop this saw as a “stand-alone” tool.  Finally, he got the message!

Weight: 

 

Aluminum three inch deep frame weighs 3.4 ounces/96.4 grams.

 

Titanium* three inch deep frame weighs 4.0 ounces/113.36 grams.

 

 

*Titanium is much stronger than aluminum, though slightly heavier.

Rigidity: 

 

The rigidity of the frame determines how much blade flex occurs. 

 

A weak frame increases blade flex, increasing blade breakage.

 

A weak frame reduces your control of the blade.
