Thinnest Kerf Saw
« on: April 17, 2021, 12:34:13 PM »
I have need to cross-cut blanks to 10", or as close to that as possible, maybe 9 15/16" at shortest.
The lumber as purchased is 30" in length.
I would sure like to get 3 blanks out if each stick.
The lumber is 1-3/4" square.
I believe most of my radial saw or miter saw blades take about 1/8"
That'll cut things way too close, shaving that 1/16" off each of the first 2, but leaving me 1/16" shy on blank #3.
What type of saw is best for that thickness but take the least amount of kerf??
Japanese razor saw? Can they cut 1-3/4" stock?
I'm not sure I can cut too squarely on the bandsaw..

One end of the project parts has a slight angle which may make it possible to cross cut at a slight angle to make 2 blanks facing each other.
But, I would prefer to cut square.......

To achieve a REALLY thin kerf requires a REALLY thin blade.  That gets iffy in thick materials and requires a great deal of patience.  A scroll saw would serve you well but the thickness of your wood would certainly create a difficult situation.  Perhaps a hack saw with a metal cutting blade, but you'd still be trying to hold it square.

A jap cut will be the best, IMO. It is still flimsy enough to need a guide for thick deep cuts. Maybe a miter box.

Other thinner blades are more for non square/straight cuts.

My bandsaw wood blade has a 1/32" kerf. A Jap pull saw is probably close.

Thanks, y'all.

I thought about using a coping saw to make a serpent cut,but
I found that my chop saw cuts an .083" or so kerf.
I laid out 2 parts nested nose to nose on a 19-7/8" length and, with an 11 degree angle cuts 'bout perfect!

I guess that's how I'll do it.
Now, I'll have to pay closer attention to grain orientation and which side goes up........
