TomP Posted April 19, 2014 Report Share Posted April 19, 2014 I hope this is the right place to ask. I am on my 3rd cutting board. The problem I still have is the Purple Heart and maple are getting burnt marks on them when I make the cuts. I have tried different blades with no success. Any suggestions or what do you use.

rodger. Posted April 19, 2014 Report Share Posted April 19, 2014 May sound like a silly question, but are the blades sharp? Are you getting buring in the crosscut or the rip, or both? Quote Link to comment Share on other sites More sharing options...
TomP Posted April 19, 2014 Author Report Share Posted April 19, 2014 I have used new blades. Getting in both cross cut and rip. Can't get the right tooth number maybe? Quote Link to comment Share on other sites More sharing options...
Eric. Posted April 19, 2014 Report Share Posted April 19, 2014 Fewer teeth means less burning and more tearout. Quality makes a difference when it comes to blades. Also power...if you have an underpowered saw, you might want to try a thin kerf blade. When making end grain cutting boards with a checkerboard pattern, you find the need to both rip and crosscut, so a combination blade would probably suit you best if you're lazy. If you're not lazy, a dedicated rip and a dedicated crosscut blade will give you the best results. Also, hard maple and purpleheart are both very dense woods, and the purpleheart is oily to make things worse. A little bit of burning is hard to avoid entirely. I just made a few myself with the same woods...with a 3HP cabinet saw, and a sharp Forrest combo blade. I had a little burning. That's what drum sanders are for.

TomP Posted April 19, 2014 Author Report Share Posted April 19, 2014 Thanks Eric, I will try that. I will have to meet up with you next time I am n St Louis to visit my daughter and son-in-law 1 Quote Link to comment Share on other sites More sharing options...
Jim Heinbuch Posted April 19, 2014 Report Share Posted April 19, 2014 A fully aligned table saw (blade, fence & mitre guage) is also very important. If the wood is being forced into the back of the blade it will have a tendency to burn. 2 Quote Link to comment Share on other sites More sharing options...
TomP Posted April 19, 2014 Author Report Share Posted April 19, 2014 Thanks guys. I bought a 24 tooth blade and carefully cut each piece. It worked great. No marks. Quote Link to comment Share on other sites More sharing options...
Autorotate Posted April 21, 2014 Report Share Posted April 21, 2014 hi Tom, Its a little late but I had the same problem and did the sam thing you did I bought a 30 tooth blade and same result, it worked great. that being said Im really glad I could help you. LOL Quote Link to comment Share on other sites More sharing options...
TomP Posted April 23, 2014 Author Report Share Posted April 23, 2014 Hi Bart. I bought a Diablo 24 tooth and it worked. Marc suggested a Forrester Woodworker blade. I think it is a 30 tooth blade. It is never too late to help out. Thanks. Quote Link to comment Share on other sites More sharing options...
jHop Posted April 24, 2014 Report Share Posted April 24, 2014 The main benefit of the Diablo is the price... you can get three for the same price as a Forrest. (at least the last time I looked.) Tradeoff was that the quality required you to go through three in the same time that it would take you to wear out one Forrest. So, you gets what you pays for. And there are some days when I'm just fine with that. Glad to hear you've overcome a (hopefully) minor issue. Quote Link to comment Share on other sites More sharing options...
STL Woodguy Posted April 24, 2014 Report Share Posted April 24, 2014 Something else that can be tried by anyone encountering this issue again on difficult boards is cutting just a hair oversized, then just skinning off the edge to appropriate size. Since it's just a skim cut, less chance of burning. Quote Link to comment Share on other sites More sharing options...

I have to ask though, with regular shop use as a hobbiest (couple nights a week of cutting), how long might a Diablo last compared to the Forrest? I know this question is hard to ask, but maybe throw some numbers out there. Quote Link to comment Share on other sites More sharing options...
jHop Posted April 24, 2014 Report Share Posted April 24, 2014 I don't have hard numbers for you.... but I don't own a Forrest blade yet. I'm still using the Diablo I purchased a few years ago. I also don't have a table saw, so I haven't felt the need to upgrade to one yet. (My primary power saw is a circular saw, and I swap out between the 24 tooth and the 40 tooth probably every other project. I've been working with a lot of plywood lately, so I've been leaning on the larger tooth count more.) Quote Link to comment Share on other sites More sharing options...

I know this question is hard to ask, but maybe throw some numbers out there. I have 2 diablo blades, and they last a while between sharpenings. I have used them for about a year or so, and just had them sharpened. I have the combo blade in the TS and the general purpose in the mitre saw. Both are great performers, as long as you use zero clearance inserts. Quote Link to comment Share on other sites More sharing options...
knotscott Posted April 25, 2014 Report Share Posted April 25, 2014 I have to ask though, with regular shop use as a hobbiest (couple nights a week of cutting), how long might a Diablo last compared to the Forrest? I know this question is hard to ask, but maybe throw some numbers out there. There's really too many variables in play to say with any accuracy.....initial sharpness, # of teeth, tooth geometry, cleanliness, moisture content, density, technique, saw alignment, etc., are all factors. Both have similar quality carbide. The Forrest has more of it, but that only means more sharpenings, not longer edge life. Quote Link to comment Share on other sites More sharing options...
markpelly Posted April 25, 2014 Report Share Posted April 25, 2014 I understand that there a lot of variables here. thanks for the comments guys. Quote Link to comment Share on other sites More sharing options...
