Scott, thanks for the blog. It is well written and informative. I certainly learned a great deal from it.

I am looking forward to the next one.

Great info Scott…
Let me ask you this on the subject of thin kerf/blade deflection…I was recently ripping some 1 1/2” hard maple pieces on my new unisaw with my 3/32 thin kerf Forrest WW2 40t ATB blade. I was making an end grain checkerboard style cutting board. After I did a glue up and cut the blank and started flipping pieces I noticed my lines weren’t matching up. When I looked closer it seemed like the cuts were angled slightly. I dialed the saw in before I started working and everything from the fence to the blade was dead on straight and parallel. The arbor has no play or run out in it..its practically brand new. I was using the blade without the recommended stiffener plate. Do you think the blade could have deflected slightly to throw off my square cuts? If it’s not that then maybe I was thinking I clamped things too tight….I’m not sure whats going on. Any thoughts?

David – Were you just trimming an edge off…as in, were both sides of the blade buried in the workpiece or was one edge exposed? That type of situation could certainly lead to some deflection. My thinking is that it generally takes lateral pressure to cause deflection.

Also, 40 teeth in 1-1/2” hard maple is pushing the limits of the blade, meaning more heat and complications from that.

What kind of throat insert were you using?

....just guessing out loud…

Well I was getting a little burning..probubly like you said..I should have been using a 30T blade…so I was cutting over and then doing a cleanup cut…so I guess it was both..blade buried and then the cleanup cut. I was using a zero clearance insert..commercially made phenolic. The blade as far as I can tell is flat….when I check it on my saw top. I think I am going to invest in a 40T ATB WW2 and a 30T ATB ww2 both full 1/8” kerf. Then I will get this blade sharpened and then hang it on the wall….

Interestingly enough, I just got through removing the blade, cleaning it and re installing it…this time with the stiffener plate. Before it was rubbing on the zero clearance insert. I had sanded the ZCI a few times but it still rubbed a tiny bit. After re installing the blade with the stiffener plate it now runs smooth without touching the ZCI at all…..hmmmmmm

Scott, thank you for taking the time to write this. Didn’t read it in its entirety now (late, too tired at the moment) but it’s in my Favorites and when I’m looking for a blade I’ll be here reading it first.

Thank you for sharing this. Along with the many things I learned from regarding band saw machine and band saw blade basics, I sure will remember what I got from this article. Please keep sharing important articles like this.

@knotscott— Very well done treatise on table saw blade selection. I am shopping now for a combination blade for my Craftsman table saw, and I will use your posting as a reference. I am looking at a standard kerf Freud 40T or 50T combination blade. I am almost done with the operational issues so I am on to getting a new blade and fence.

Great work, Scott!

Have you ever thought of setting up a Spreadsheet shoing all of the various blades and their properties?
...looks like you may have all of the information… just takes a little work…
... while you’re at it, you could assign values to the different properties and insert them instead of symbols, etc.
... then, you just add up the property values to get a score…
That would be interesting as all get out…
... might be able to publish your findings & make a little blade money! LOL

Thank you.
