Hi all,
i'm waiting for my new bandsaw to be delivered, and i'm trying to get a few blades while i wait.
One question regarding thin kerf: i make guitars and to make the bindings i laminate a small board of indian rosewood (3/16"x3"x31") with 3 alternating veneers (maple-rosewood-maple). Since it's some work and material, i really like to get as many slices (7/64") out of it.
So far, since my bandsaw was pretty sloppy, i was using my tablesaw with a metal cutting blade, with a total cut of 1mm or 0.9mm. Problem is, i had to sharpen it every small board, otherwise it started wandering in the cut for being dull. So much so, that i lately started using a very thin kerf carbide disc, but the total cut is now 1.3mm. To me it does make a difference.
So now, with the new BS, a Hammer N4400, i'm thinking to get a thin blade to rip those bindings, but i'm not sure what the best option is. Locally, i can get Starrett blades, and in the catalog i see a few interesting options:
3/8" x .014 either 6tpi skip or 14tpi regular
1/2" x .020 either 10tpi reg. or 14tpi reg.
I was thinking to get the 1/2" 10tpi; the reasoning being that a slightly thicker and wider blade might offset the thinner blade's advantage cutting straighter and cleaner. The 14tpi seemed too much though for almost 1/4" of rosewood.
Do you think that's correct, or i could save a little more material with the 3/8" 6tpi? What total kerf should i expect with both? Any other thoughts?
I hope that in some way i will be able to get a slice or two more with the bandsaw than i'm getting with the TS...
Thanks a lot for all the suggestions,
Daniele.
