Ok so I finally got this saw running properly. I bought this thing knowing that I would be upgrading the motor. I added the riser block and of course it was way too underpowered. I think part of it was that I didn't have it tuned up properly. I upgraded to a 2hp motor, added a link belt, and bought a timber wolf 1/2" 3 tpi blade. I had the saw tuned up with a horrible blade, and it was cutting OK. Now with the new blade, we are in business. Still have to get everything put back together.

What brand of Saw is that? I think a 2 hp motor would make a big difference. Is it 220?

If you don't have time to do it right the first time, when will you have time to do it over?

It's the harbor freight model. It's running on 120 at the moment. Yes that motor made a world of difference. It's hard to tell what made the biggest difference between getting it tuned, upgrading the motor, and getting a better blade because it all kinda happened at once. I resawed some
Mahogany and red oak about 6" wide with no problem at all. I do know when I first used it completely stock, the saw was having trouble on a pine 4x4.

Looks good! I just got the wood slicer blade in today, (yesterday now) and plan on putting it on within the next couple of days.

Good Morning,

I got the new Highlander Wood Slicer blade in and on and it makes a really nice cut. I'm wishing I would have bought a quality blade a long time ago.

Quick question. What is a good speed to run the bandsaw at? I mostly cut soft wood but do the occasionally cut a little hard wood.

EDIT: How to convert 1640 RPM to FPM or SFPM?

Thanks,

Gary

Any change to your RPM will be by changing your pulley size.
Bigger pulley at top for slower.
Smaller pulley at top for faster.

If you don't have time to do it right the first time, when will you have time to do it over?

How do I figure out which is 3000 FPM?

Thanks,

Gary

I don't know the answer. Personally, I think I would stay with the original pulley sizes from the factory. I think they would know what speed their saw performs its best.

Plug your pulley sizes in here to get the RPM of the drive wheel:
http://gadi.agric.za/software/renting/pulley_calc.php

A 14" wheel has a circumference in inches of C = IID or 3.14 X 14" or 45". Divide by 12" to get feet or 3.666 ft.

Multiply by drive wheel RPM from above calculation, to get FPM


Most bandsaws from from 3,000 to 5,000 FPM.
The 5,000FPM is for the Industrial size machines:
http://www.grizzly.com/products/19-U...ce=grizzly.com

The smaller cast iron saws are around 3,000FPM. The welded frame type is 3,000 FPM:
http://www.grizzly.com/products/14-2...ce=grizzly.com

I would aim for 3500 FPM IF you feel it's necessary to even change speeds....?

The answer to your question will only be as detailed and specific as the question is detailed and specific. Good questions also include a sketch or a photo that illustrates your issue. (:< D)

I had to find a pulley that would get me the right FPM and I calculated with the pulleys I bought that I'm running 3300 fpm. If your saw is still stock then it's got 4 speeds, the highest being 2500ish FPM

Thanks for the reply. Yes, mine is still stock. I only said 3000 because I read somewhere that that was a good number for cutting wood and I don't want to dull my new blade to early. I will set it at it fastest setting (which is 2670 RPM) and leave it.

Thanks,

Gary

Thanks for the reply and info. I think I will just set mine to the fastest setting and leave it.

Thanks for the reply. I'm not looking to change pulley sizes. I didn't know if one of the factory settings was 3000 FPM. One of the other posters said that it wasn't so now I know.

Thanks,

Gary

Here is a calculator for blade speed, instead of wheel rpm.

I changed a pulley on my old Delta bs, and went from 2200 sfpm to 3160 sfpm, and it was a great improvement.
