blades have a lot to do with resawing hardwoods :<))

If it fits and is the correct RPM, it will work. But as already stated use a correct blade.

Compressor motors are not usually intended for “continuous” operation. They are intended to cycle on, run a bit, then cycle off. I’m not sure at what point you would be running the motor too long. I would guess the biggest weak points would be bearings and the ability to get rid of heat…

Don’t use a compressor duty motor on your bandsaw. You need a continuous duty motor, especially if you’re doing resawing. My guess is you’ll burn the motor.

You’re about to throw good money after bad.

First of all, you just bought this saw. The HF 14” is a Delta clone, and for what it is it’s fine, but it’s not supposed to be a dedicated resawing saw. It will work though if you:
  • have set up the saw properly
  • use a new, sharp, wide, low tooth count blade
  • go slow
  • [did you buy the riser block for the saw to give you more resaw capacity?]

All a higher HP motor will allow you to do is mess up your wood faster if you don’t have your saw set up correctly and are not using a sharp blade.

This is why you’re about to waste even more money: You just spent roughly $300 on a saw, and you want to spend another $150 on a different (incorrect) motor. That 2HP compressor duty motor draws 17 amps at 120. Do you have a 20 amp circuit to handle it? If not, that’s going to cost some money for the new breaker, wiring, and outlet. Same thing if you want to run the motor at 220 and you don’t have a 220 circuit. This applies to any motor that’s more than 1.5 HP, by the way.

So assuming you’re got to do some electrical work you’re looking at spending at least $200 more to upgrade your HF 14” saw. For the $500 or so you’re looking at putting into this project, you could have bought a larger used bandsaw on Craigslist, if you’re patient. For example, there was an old 16” Powermatic beast near me for $550 recently.

If I were you, you already have the saw. Buy a high quality resaw blade, get the saw set up properly (google “Snodgrass bandsaw setup video”), and figure out how to use what you have for a while. If you then determine that the problem is for sure the motor and not the saw, look for a good continuous duty motor on Craigslist, and make sure the RPM and spindle size are compatible.

Yup, snodgrass setup. Weaker motor only means you may have to move slower. Blade choice and setup determine your success or failure.
Spend 3x the money on a blade, and nothing on the motor, and you should be happy.
Oh and if its dry and hard, like hard maple, you can try a bimetal blade.

I have a similar situation with a Craftsman 12” (Rikon clone) bandsaw. Snodgrass setup, 0.5”, Woodslicer blade, and slow feed rate.

It’s one of the reasons I have my eye on a 14”+ steel frame 220v saw, but yours will work, albeit alowly.

The blade in my band saw has a high tooth count. designed for cutting steel. I like this for smoother cuts on wood. But the 2 big disadvantages are; must feed the boards slower, and cutting any sort of round pattern is more work. The blade type makes a large difference in performance.

Have your say...
