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.

"If I spend my hard eraned money on an airgun, especially a mid to high end airgun and it has any issues whatsoever, I'm boxing it up and sending it back where it came from. Nope, nope, nope... don't say you fixed it and send it back to me. I didn't buy a refurb and I don't want a refurb back.
Show me your customer service.. Take a new gun off the shelf and have your tech verify that it passes all the quality checks then send it to me. No sir... I don't want a discount or a store credit or a partial refund... I want exactly what I paid for and exactly what you said you were selling me. If you can't do that then stay out of my mailbox with your spam mail.
That's part of the problem with retail these days.. We, the consumer settles for whatever shovel full of stuff they feed us.
Shame on us for that."

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........
