I asked this same question on MIMF, but thought I would ask here as well.

What size Bandsaw blades are you guys using to cutout the back/top and cutting the sides?

If you are selecting a blade solely for cutting thin materials (Top, Side, & Back) you want to use a fairly fine tooth configuration such as 18T. Given that the contours do not have real small radii you can use a slightly wider blade such as 3/8" or 1/2". A Skip Tooth blade should be better for soft materials such as wood.

With that said I typically keep a 1/4 Blade on my Band Saw as this allows me to cut a number of items. This works for Tops, Sides, and Backs as well as smaller radii cuts on necks. 1/4" blades are commonly provided with either 4T or 10T. A 4T will cut about anything, including thicker materials. The 10T blade will not perform as well if you are cutting thicker materials. It's easy to overfeed and bog down the saw.

One thing that I do to prevent tear-out, especially with a 4T blade is to back up the material you are cutting with a piece of 1/4" ply. This will dramatically reduce tear-out. Hold the material snugly to the backing board.

I would recommend that you go to the Olson website and look at the Band Saw How-To section (

there is a rule of thumb about how many teeth you want in your work. I typically use 6 TPI on fine work 4 tpi for work over 1 1/2 inch and 1 2/3 tpi for resaw.

You will want at least 2 teeth on the work at all times, so measure the thickness of your work piece, and measure the distance between teeth on your blade.
