Brac Posted April 15, 2011 Share Posted April 15, 2011 Not sure what you mean by "riving the cut". Regardless, I don't use one on my own saw, I have used saws with them. They should have no effect on the quality of cut. If I am mistaken, feel free to show better info as I am always happy to learn. Blade choice and sharpness is the biggest factor in getting a clean cut. BTW. my TS-55 cicular saw does have a riving knike, and also make very clean cuts.

Mallette Posted April 15, 2011 Share Posted April 15, 2011 rive [ra?v] vb rives, riving, rived, rived, riven ['r?v?n] (usually passive) 1. to split asunder a tree riven by lightning 2. to tear apart riven to shreds 3. Archaic to break (the heart) or (of the heart) to be broken [from Old Norse rifa; related to Old Frisian riva] Frisian, no less... Anyway, easier to post that to explain that which I can't get to work. A riving knife is to perform the above just behind the saw blade and ensure the blade does not spin against or get bound in the kerf.

Brac Posted April 15, 2011 Share Posted April 15, 2011 If the wood is rubbing the back edge of the kerf, then the fence is out of alignment. Trust me on this one, if you get the fence set correctly, and a quality blade, made for plywood, you will get a good cut. Quote Link to comment Share on other sites More sharing options...

tromprof Posted April 15, 2011 Share Posted April 15, 2011 I was originally looking at the Table Tuba as well, until I found out it only goes to 30hz. . Mike Not true. A 20hz test tone on my tuba table is loud and strong (and shakes the window glass!), so it is great fro home theater. The larger Tuba HT will go to 10hz !

CECAA850 Posted April 15, 2011 Share Posted April 15, 2011 The larger Tuba HT will go to 10hz ! That's contrary to what I've read. Do you have a link? Quote Link to comment Share on other sites More sharing options...

From Bill Fitzmarice's website: "Not impressed yet? Add in the cabin gain of an average room (12dB per octave below 30 Hz) and you can end up with flat response to 10Hz with 110dB sensitivity." ( http://billfitzmaurice.net/THT.html ) Sounds like the right room and good placement will have something to do with it though. Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted April 15, 2011 Share Posted April 15, 2011 With room gain, it makes sense. The sub by itself is flat to 20Hz or so. Quote Link to comment Share on other sites More sharing options...
