Topic tags/keywords: maple saw burn

I have several 6-8 foot maple boards that need about 1/2 inch ripped off. I know (from experience) that cutting maple can cause burns. Since I am a novice at this, I was wondering what, if any, the trick is to doing it without burning. These were expensive pieces and I really really need them nice and clean. The boards are a hail over 3/4” thick and 6-8 feet in length.
I have a DeWalt heavy duty job site table saw and the following blades: a B & D Firestorm 200 T plywood blade, a DeWalt 60 T cross cut blade (came with the saw?), and an Irwin Marathon 80 T trim/finish blade. Of course, I could buy another blade but I am hoping that it is “technique” rather than equipment!
Any help/advice you can offer is much appreciated!

Ellen, here is a picture of some cherry I recently ripped on my table saw. Cherry is notorious for burning, even more so than maple.

Milled Cherry

Some burn marks are simply inevitable when milling wood but this can be mitigated by (1) making sure that you have a SHARP premium blade in your saw. I use only Forrest blades (2) make sure that your blade and fence are aligned. With my Craftsman saw I occasionally spend up to 10 minutes aligning the fence and blade for each cut. With my fence the front and rear of the fence can end up being angled if you simply set the blade to fence distance and lock it down. Here is a picture of my saw and the “fine adjusting tool” that I use to align the fence:

And (3) did I mention use a SHARP premium blade. :)

Hope this helps.

Buy a good rip blade. A crosscut blade will definitely burn, and based on my experiences with the blades that you already own, the heat generated can cause the teeth to become suddenly independent of the blade.

I would suggest going to www.royceayr.com

I have some blades from them that are 25+ years old, and still great. They also service what they sell.

Make sure you are sitting down when you see the prices though.

Raising the blade high above the wood reduces burning also, the Forrest rep gave me that tip at a recent woodworking show where he was cutting cherry without burning. He also used blade stabilizer.

If you get significant burning then chances are your fence is a bit closer to the back of the blade than the front. This causes the wood to be pushed into the teeth at the back of the blade. Those teeth don’t really cut the wood very well, though, because they are going in the wrong direction. You might actually be able to look at the burn marks and see the direction of the burn; meaning the shape of the burn will look more like the arc of the back of the blade than the front.

The solution then would be to adjust your fence so that the back of the fence is pushed a bit more to the right (assuming your fence is to the right of the blade). It’s even OK if your fence is the slightest bit out of parallel to the blade, as long as the back of the fence is further from the blade. This might cause a bit of burning on the waste side of the cut, but it should be minimal, since there is no fence pushing the wood into the back of the blade. The only source of pressure would be from the wood itself and there isn’t anything you can do about that.

Thanks everyone. I just found a Freud 24 T rip blade for $60 locally. I think I may try to pick this up…unless I hear it is a dog!

ellen…all of the above is super good info and correct..however if you will cut your wood close ,say to within 1/16, then skim the last 1/16 in as smooth and flowing a cut as possible, trying not to have “pauses” in your feed rate you will not get burns and you will also get a nice smooth cut…I often use the freud 24t glueline rip, its a super blade…personally i prefer the freud blades over most of the other expensive ones..which I have.

Charles has a good point… that’s what I sometimes do – cut it a little
wider and then saw, (or joint) off the stock. This is actually pretty
smart for cabinetmaking in general… rip a little wider, let the board
move, then joint and rip again to final width. Reduces burning and
gives a straigter board. I learned it from one of Jim Tolpin’s books
and when doing doors or face frames that’s always my procedure.

Also as well as making sure your blades are sharp ,don’t feed too quickly, and add a little spray wax on the blade frequently and you’ll notice a big difference Alistair

spray wax????
what do you mean?
I assume set up means getting the blade nearly/exactly parallel with the fence….

Yes, what bently and everyone else said. If you get a lot of burn, it’s either a dull blade or a fence (and or blade) out of adjustment. Just take your time and tackle one at a time, you’ll get it. Good luck.

If possible I’d also cut down the 6-8 foot lengths to a little longer than what your project needs. I find it hard to control such a long board without a helper.

I agree with bentlyj also…I invested in a 40 tooth CMT for about $90 and it does everything. Not only rips great, without burns, but also crosscuts good and is great on plywood and melamine. If you’re planning on investing $60, why not spend a little more and get a blade that can do it all. Just remember to keep it clean.
