Hi Folks,

Quick question on the Resaw King…

How long do these typically last? I got mine about three years ago for my 1412. I can count on one hand the number of times I’ve actually resawed wood (I very rarely use my bandsaw for that matter).

Today I was resawing some 6” wide 6/4 poplar into 3/4” halves. After the second piece, the blade seemed to be be cutting differently (almost like it was moving back and forth, so the cut was choppy). I went to turn off the saw, and before I hit the button, the blade snapped. It wasn’t even under load at that point. (a 3’4” blade snapping under tension will definitely wake you up).

I always release the tension on the saw, and again, I haven’t cut very much wood with it. I also have the guides set up EXACTLY as listed in the 1412 manual (no Snodgrass method for me). I don’t remember exactly what I paid, but isn’t this a $200 blade or so? Seems like it should last waaaaaaaay longer. And it did not snap on the weld.

Well that sucks because it’s a $150 blade. It may have been a bad weld. I have that blade on a14” and hope mine last along time.

I just realized you said it didn’t break on the weld. It may be the downside of running a 3/4 blade on a 14”” saw.

I had one years ago for a 20” saw that
broke after a year or so. Laguna was kind
enough to replace it. The second one lasted
a long time and was on the saw when I sold it.

One thing I didn’t think to ask was are you bottoming out the tension spring when tighten the blade? That can cause a blade to break from not having any give in the tension if hitting a hard spot in the wood. The tension spring becomes like a shock absorber that’s bottomed out. It won’t absorb any shock.

14” saw?

Could be metal fatigue. Early carbide tipped blades were only recommended for 20”+ saws since the smaller diameter wheels tended to over-flex the metal, eventually causing failure. I believe this is still the case for thicker blades.

Either way, that break looks clean ‘nuff so if the rest looks ok, I’d just get it re-welded.

I’ve never broken a Resaw King blade but my saw has a 20 inch wheel. I also leave my blade tensioned unless I’m out of the shop for a week or more.
But you might consider leaving your saws blade untensioned.Plus it is a very lite duty saw.
This is from Timber wolfs site I think.

ALWAYS DETENSION YOUR BANDS
When you are done cutting for the day, take the tension off your blade. Band saw blades, when warmed up from cutting, always stretch; and upon cooling shrink by tens of thousandths of an inch each cooling period. Therefore, blades, when left on the saw over tension themselves and leave the memory of the two wheels in the steel of the band, which will cause cracking in the gullet. When you leave the band on your saw under tension, not only do you distort the crown and flatten out the tires (which makes them very hard), but you also place undue stress on your bearings and shafts. Believe it or not; you can, and will damage your wheel geometry sooner or later and considerably shorten bearing life. You are also crushing your tires or V-belts.

Not to argue with Timberwolf but perhaps as a manufacturer they are being prudent and covering their asses against the worst possible case end user.
I have been using bandsaws commercially and as a hobbiest for nearly fifty years with sizes from 10” to 42” and have never either de-tensioned nor seen any of the above problems. My guess is that the majority of bandsaws never get de-tensioned but that’s just my guess.
Not wanting to start an argument, just surprised to read something like that so contrary to my experience.

I agree I don’t either.
I also don’t run a 1 wide carbide tipped blade on a 14 inch wheel.If the op has the same blade as mine then it’s .025 thick and that’s very good for a small wheel.But 1 inch wide that’s a lot for a small wheel.

I have a Shop Fox 1706 bandsaw with the extension neck, 105 inch balde. I recently installed the Resaw King and it has been working great. Installation was easy and didn’t give me any problems. It is the best blade for resawing that I have used and I am very happy with it, yes it’s .25 width 3/4 inch and that’s the largest blade my saw will handle.

Who said anything about a 1” blade on a 14” saw?.

I did because it looks like a 1 inch blade the op has on his saw that broke.I have two of them I use on my bandsaw but it’s a 20 inch saw. If he does get someone to Reweld the blade he might want to untension it when he’s not using it.
I’m ok if you don’t agree with me I have thick skin from roofing.:)

One thing I found useful was to measure the tension on the band saw blade. I did it following the Woodgears site method using a digital caliper. I did it a couple of times to understand how well the blade tension guide worked.

I wonder if taking the tension off the blade is more important for the bandsaw than the blade. It would be more important for smaller band saws using larger blades.

I didn’t understand your 1” comment because the OP said it was 3/4”.

No problem, Why Me .. I totally missed that. I guess it doesn’t matter anyways…..Laguna has their own thing going with their saws and blades so if they say the saw will tension a RK blade so be it.

I had the exact same experience with my 1412 and the resaw king.
I moved into a house…never mind the details. Just know I don’t have room for a tablesaw anymore. ☹️ So I was trying to get by with a track saw and bandsaw. It’s been two years and it’s working out OK.
Anyway, after that experience, I switched to Timberwof and haven’t looked back. No more broken blades since then. What I can advise is to use the bandsaw more. You might be surprised at how experience with it will improve your results. And yes, I do de-tension it after each day in the shop.
