I was thinking of doing this on the BT3000 but thought I better check here first. The 3' long fir was recently milled by a friend but it is too thick & I need to rip it in half. I was thinking of making a few passes, then flipping it over & cutting through, but I would have to take the guard off for this. I recently bought a pair of grr-rippers & was wondering if anyone has cut something that thick using them?
ripping 6x6 fir -- bad idea?

The guard is not gonna help you anyway, as the work is too thick for the blade to be exposed during the cuts (but keep the riving knife portion on the saw). Your method will work OK, but if you have a bandsaw it would be easier, though not as precise. On the table saw, just remember to flip the workpiece end-to-end, not side to side. This keeps your fence setting properly referenced. You should also use a featherboard or some such to keep the work tight against the fence, and if the piece is long, you should provide some outfeed support. Make your first cut about an inch deep, and then increase the depth another 1/2"-3/4" on the subsequent passes. Do the flip just after the piece is cut halfway through, and repeat the steps (your max blade height is only about 3-1/2" anyway). Do not stand in the line of fire, in case you get a kickback. Do not feed the work too fast, and give the saw a chance to cool between passes if you think it is working too hard. Also, have some wooden shims on hand to wedge the kerf open and keep the blade from being pinched. Things will be easier if you have a helper, but make sure not to get in each others' way.
Caveat: I'm assuming the 6x6 is dry and straight. If not, the difficulty goes up considerably. Oh, and a Grripper is a useful tool, but take the other precautions, too. Be aware of any knots and how they might affect the cut, and be prepared to have to sand or plane the cut face, as multiple cuts don't leave the smoothest of surfaces.Last edited by Uncle Cracker; 09-13-2009, 10:01 AM. -
+1 on everything UC said.
One more thing I'd do is add an extension to the rip fence if the 6x6 piece has any length. Trying to keep a long 6x6 snug to the standard fence may be a little tricky.
Oh, and I'd use a full-kerf blade and use more passes (raising the blade a little less each time).Last edited by cgallery; 09-13-2009, 10:46 AM.Comment

Only one thing to add to that. Use a sharp, clean blade.
EdDo you know about kickback? Ray has a good writeup here... https://www.sawdustzone.org/articles...mare-explained

Ditto on C-Man's blade advice. Lowe's and HD sell a Frued 24T coated ripping blade that won't break the bank.Don, aka Pappy,

What the others have said. Incase I missed this, or it wasn't there, do not rip all the way through. Leave a little wood in the middle and finish the cut with a hand saw.From the "deep south" part of Canada
