I did quite a bit of research on bandsaw blades for my Laguna 1412. What I’ve found from past use is that this saw really needs thin gauged blades (0.025”).

I’ve been using the flexback blades from Ellis and they worked well but I wanted something that would last a little longer so I ordered a couple of Lenox Diemaster 2 Bandsaw blades from Hastings Saws – 4 tpi hook.

When I got them they were both just thrown in a box together without any sort of padding between them. I pulled them out and was a little disappointed at the welds.

Not great but I ended up filing that slag down a little and installing it into the bandsaw. The good news is they cut straight but they seem to make a knocking sound as I cut.

I’ve uploaded a video here:

Bandsaw Blade Knocking Video

Is this normal?

My last blade was so dull I didn’t really pay attention to what it sounded like so I don’t really know if this is going to be a problem going forward. I wanted to ask you guys to see what you thought before I contacted the company about it, or if I should contact them at all. Like I said they seem to cut straight but the sound seems strange.

And for comparison here is the weld from Ellis that I removed from my bandsaw.

Thank you kindly for your help.

The knocking noise you are hearing is the weld out of round with the rest of the blade. Should not be doing that. It will give you a lower quality cut, and may be putting undue pressure on bearings when it comes around and slams into either a side bearing or a thrust rear bearing. You might be able to see a repetitive cut mark on the wood if you push it through at a steady rate, and when finished, look carefully at the wood for a more pronounced cut mark that repeats. That is the bad spot on the blade.

Obviously it cuts, but for me, that is the sound I usually hear when my blade is right at the end of its service life, and the blade is about to pop. Something has bent, and its time to remove it. I tend to run my blades as long as I can, but when I hear that noise, I know its time to turn off the saw and get a new blade on before the dreaded explosion of the blade snapping.

I have been using Starrett “Woodpecker” blades with good results. The welds are so perfect, they are hard to see. I started using Starrett from day one and see no reason to change. There may be other good blades out there, but Starrett fills my needs completely.

Yep, grabbed the offcut from the trash and sure enough:

Thank you for the sanity check. As these are brand new blades that obviously shouldn’t be happening. The thing I noticed about blades before was – nothing. I just put them in and got to cutting. Am going to send these back and find another option. I almost ordered the Lenox trimaster blade from this vendor but now am obviously glad I didn’t.

Will give the Starrett blades a look. Also was considering the Supercut Blades – anyone use their gold or resaw blades? Basically I wanted something to throw on the bandsaw and leave there – not have to think about it for awhile, which is why I wanted a bimetal blade. I liked Ellis but unfortunately they didn’t have the 1/2” bimetal in the tpi I wanted (3-4).

Why would you want to use a bimetal blade? They are usually used to cut metal and although you can cut wood with them, they lack the flexibility of a flex back carbon steel blade and require more tension to get them to track properly.

From what I’ve read the consensus is bimetal blades last considerably longer. I use my bandsaw as my main saw – so 95% of my cuts are straight cuts not curves. I also resaw somewhat regularly and that tends to dull blades pretty quick.

My primary bandsaw blades are the bimetal Lenox Diemaster 2, 1/2” 4tpi and 1/4” 6tpi and I have been quite satisfied with each with no complaints about the cut. I purchased the blades from bandsawbladesdirect.com and the welds looked great and were nicely finished, also they had one of the best prices. The only thing I did to the blades was use a stone on the backside to round the sharp edges. My saw is a Laguna 18BX and I chose to go bi-metal for the extra blade life (my resaw blade is the 1” Laguna Resaw King).

Thanks for the tip regarding stoning the backs. I’ve heard different reports on whether or not that’s necessary on the Diemaster 2 blade. I did look at bandsawbladesdirect but the free shipping from Hastings at $75 vs $100 and the slightly lower cost got me. That said I just got a return label from them so they are professional to work with – seems their welder just had an off day.

+1 on bandsawbladesdirect.com

I have at least a dozen Lenox blades from them in sizes from 1/4” to 1” all have been nicely welded.
