TS Splitter
I haven't used the guard or splitter for my Jet Contractor saw since
I bought it. I didn't think it was needed because I primarily cut plywood and smaller pieces and rarely needed to rip any lumber. Last week I needed to rip some 8' 2x4s so I thought it would be a good idea to install the safety device. Worked fine and probably saved me from injury since the 2x4s twisted and bowed like crazy as they were ripped. After that I went out and bought a decent blade (Freud finishing blade) because I was installing a new kitchen and had to cut finished materials - fillers, toe kicks, etc. This is when I noticed a problem, even though the splitter was lined up with the blade, the wood would bind between the splitter and the fence. The finishing blade is the same width as the splitter. I want to keep the splitter and guard so what do I do? A few thoughts I have a Sand the splitter to make it thinner Add an auxiliary fence that stops short of the splitter Aftermarket splitter and guard Zero-clearance insert with 'splitter' Adjust the splitter further away from the fence side of the blade I like to hear any thoughts on these or any other ideas. I want to keep the safety of the splitter and guard. |

"Reaction wood" I've heard it called. Tom. |

Original owner tossed them and I've yet to come up with a replacement. even though the splitter was lined up with the blade, the wood would bind between the splitter and the fence. The finishing blade is the same width as the splitter. I want to keep the splitter and guard so what do I do? A few thoughts I have a Zero-clearance insert with 'splitter' I opted for this solution. Took a good quality phenolic zero clearance insert and will mount the Micro Jig Splitter on it. Picked mine up (I bought the 1/8th ") at Woodcraft last weekend. Haven't installed it yet but the install appears straightforward and well thought out. http://www.woodcraft.com/family.aspx?familyid=5067 Couple this with the pair of Board Buddies that I'm mounting on the Excalibur fence and hopefully I won't have a problem with kickbacks. If you have a Woodcraft near you, might want to go in and check their clearance table. Mine had a couple of Biesemeyer quick-release splitters for thin kerf being blown out. Price was down to about $85 IIRC and those looked like a very nice, solid unit that also has anti-kickback pawls. Unfortunately they didn't have one for my saw. |

A few thoughts I have a If the blade indeed leaves a kerf that the splitter will fit into correctly and the splitter is indeed aligned to the blade, It could very well be the stock you are cutting. It could be bowed and that will create this problem. I would not modify the splitter until I ruled everything out. |
From what you describe, I'm guessing that the new Freud blade you bought is
a thin-kerf model. So you end up with a 1/8" splitter trying to wedge itself into a 1/16" saw kerf and it won't fit. The simple solution is to swap the thin kerf blade for a full thickness one. Then the two sides of your workpiece should slide neatly around the splitter. Lee -- To e-mail, replace "bucketofspam" with "dleegordon" |

I'd double check the alignment before doing anything else. If the kerf is not binding on the splitter itself, then the blade and splitter thicknesses should be compatible. If wood is binding between the splitter and fence, it suggests that distance from the fence to the blade is bigger than the distance from the fence to the splitter. This would be an alignment issue. The other cause that has been mentioned is the particular board you're cutting has internal stresses that are being relieved during the cut and deforming the board. Try other lumber and see if the problem goes away. If you do have some wood that is moving this much, bandsawing it would be safer. Good luck, Tim |
Aw come on. That's not a very helpful reply. He's cutting cabinet
materials! You can do that on a tablesaw safely all day long and tens of thousands of woodworkers do it every day. There is something that is fundamentally wrong in his setup. Bob |
Thanks. I think.

Lots of good info so far. I've got the same saw and had a heck of a time
getting the splitter aligned. My pieces would bind no matter what I did it seemed. I cut a kerf into a board, shut the saw down, and tried to slide the board over the splitter only. It fit. That told me that I wasn't aligned properly. I actually had to bend the splitter a little to straighten it out (came a bit bent from the factory). That said, I've gone to zero clearance inserts and bought the micro jig splitter (but haven't installed it yet). I intend someday to build an overhead guard and use the stand alone splitter in the zero clearance insert. A couple of other random thoughts, make sure the splitter is perfectly 90 degrees to the table. That was one area that I had to fiddle for what seemed and eternity before it sat right. I also had to add a few washers to move the splitter to the left a bit. After all this, it cuts great. Hope you figure it out! Cheers, cc ps. I usually run with an extra board on my fence kind of euro style if you will. More out of habit than anything else. I have it extending to just inside the rear edge of the blade. Not sure if it helps or not but hasn't hurt anything. |
I have a Delta CS. I almost always used the splitter and the
anti-kickback pawls that came with the saw (minus the shield which broke fairly early in the life of the saw). Recently, I wanted to rip some 5/4 x 6" boards in two and without a BS figured I could do it on the TS by flipping the boards over and making several passes per edge. I did not want the board to close up on the spinning blade while it was buried in the board so I made a new splitter out of some 3/32" flat metal stock purchased at the BORG. The splitter is about an inch shorter than the max height of the blade. That way I could make two passes per edge and spare the load on the blade and saw. Worked so good I do it all the time now (still hankering for a BS though ...) Anyway ... the splitter I made worked out such that I now use it almost exclusively. And while it probably makes sense to use the factory one with the anti-kickback pawls on it this "mini-splitter" works so well with a zero-clearance insert that I don't worry about it very much. So go get yourself a piece of 3/32" x 1 1/2W" metal stock, make yourself a splitter and mate it with a zero-clearance insert and see if my solution works for you ...
