Hi All

Anyone got one of these and installed a thin kerf blade? Not sure if riving knife is too thick

Regards

Mark

Mark, check the riving knife it may be stamped with how thick it is. Otherwise you will have to measure how thick it is. Most thin kerf blades are around .09”.

Good luck.

Thanks CL810. Lo and behold, all the info is on the riving knife!

Says

RK Thickness .0.90 (2.3mm)
Blade Body .055=.086 (1.4-2.3mm)
Blade Kerf .094-.126 (2.4-3.2mm)

If my info is correct 3/32 = 0.094 so a thin kerf should be OK. Was going to get a tenryu gold but they don’t seem to have thin kerf

Looking at Freud. This seems to be the only choice for 24T TK RIP

Freud LU87R010 10-Inch 24-Tooth FTG Thin Kerf Ripping Saw Blade with 5/8-Inch Arbor and PermaShield Coating

Was looking at this for combo, but reviewers (on Amazon) said it burns real easy

Freud P410 Premier Fusion 10-Inch 40 Tooth Hi-ATB General Purpose Saw Blade with 5/8-Inch Arbor and PermaShield Coating

Ironically, the cheapper freud 40T TK got all good reviews:

Freud LU86R010 10-Inch 40 Tooth ATB Thin Kerf General Purpose Saw Blade with 5/8-Inch Arbor and PermaShield Coating

Given I only have 1.75HP, I feel I need a TK. Had lots of occasions where saw has just stopped mid cut (feed rate very low)

Any suggestions?

Thanks

Mark

I have the 35990

I use the Freud LU87R010, 24T and it’s a very nice blade. I’ve been working a lot lately with hard maple and cherry and we all know how easy it is to burn maple. Does not seem to be an issue. The saw is more sensitive to a good setup with a thin kerf on it and this may be true of ALL saws…. I don’t know. Too much “tail out” on the fence and you get lateral pressure on the blade and you’ll get some scorching.

Regarding stopping the blade:
Assuming you have checked your set-up and alignment and achieved the best possible ….

The ONLY time I can stall my blade is if the wood has enough tension that it wants to pinch back together beyond the blade. With a thin riving knife it’s still apparently possible to get enough pinch to do this. I’ve had to stop, wedge the kerf and continue if it gets bad, but that is an extremely rare occurrence and I hate stopping the saw mid-cut and restarting it. Usually if there’s that much tension in the wood, the pieces have to be used for smaller parts anyways.

Thanks Charlie

Alignment of blade is withing 2000th of each end of miter slot. Will check tension on riving knife next time it happens

Will go for the freuds then

There’s a bit of runout from the blade and the saw that usually gives a bit more wiggle room than just the stated blade width. My guess is that you should be just fine with most 3/32 TKs. Some are 0.90 to 0.94 (many Freuds), but you’ll find some hovering closer to .097 to -.100 (Infinity Super General, Forrest WWII, Ridge Carbide TS2000TK, Irwin Marples, CMT 214.040.10). The last I knew Tenryu did offer the Gold Medal in a TK, and it’s a good blade, but so are many of the US and European made blades.
