I did a bad ting George
I needed to hang a large, 30 x 30, corner cabinet that SWMBO had me
build. I decided to use the angled cleat method hoping for maximum strength since a TV will sit on it. Anyway... I angled the blade on my right-tilt saw to 45d and put the fence on the left of the blade. I was ripping a 4x27 inch piece roughly in half for the cleats(I didn't want to try and squeeze a push stick between the blade and the fence on the right. Expecting that the piece would want to lift up cutting it on the left, I clamped a feather board to my fence to hold down the piece. So far so good, or so I thought. I couldn't get a push stick to help me all of the way with the cut because of the clamp and the feather board so I ended up pulling the piece through from the back of the saw. I know this was wrong, so what is the right way to do this, aside from buying a new tool. |

A smaller diameter push stick - I know cats only come furry and round but a
bit of broom handle will do - even if you cut it on the rip. Alternately, cut the length of stock overlength then you can poke it in far enough for the piece you want to cut on the angle. Turn the saw off and retract it & cut the length back to what you want. Good luck.

I know this was wrong, so what is the right way to do this, aside from buying a new tool. Push blocks. Narrow versions of what came with your jointer. Pieces of 3/4 stock, for instance, cut with handholds fore and aft, three-four inches above the flat portion. Glue a chunk of mouse pad or other resilient material to the flat bottom of one to use as both hold and push, leave a 1/4" hook on the heel of the other for the final. Paint them some flashy color so they won't just look like another piece of scrap and store them with your other push sticks on a shelf right of the saw where you can grab one as required even if you forgot to preposition them. Right next to the featherboards, for instance. |

Not that this is any proof, but the guy that peddles (peddled?) the Grip-Tite magnetic featherboard at woodworking shows used to do that all the time as part of the demo. I would say that with the featherboard the OP was using he had sufficient control over the work (certainly as much as the Grip-Tite guy) that he could safely go around the back of the saw and pull with impunity. What would be the safety issue, anyway? If the blade snatched the work (unlikely with the featherboard), the worst that could happen is a spear gets propelled across the shop, but the operator is well out of the line of fire being at the back of the saw or on his way to it. -- LRod Master Woodbutcher and seasoned termite Shamelessly whoring my website since 1999 http://www.woodbutcher.net Proud participant of rec.woodworking since February, 1997 |

I always thought that the safety issue was the possibility of the
operator's hand/arm being pulled towards the blade if kickback were to occur. Now, I would hope that I'd have my wits about me enough to release the board if such a thing started to happen, but I'm certainly not willing to test that theory. -John |

Yes, the featherboard is holding it in place. Yes, it's stable, and in the sense that it's not particularly It's not completely stable. As well, I've left wood unattended for a few seconds while the blade is spining. It's often burned the wood or otherwise marred a clean edge. How is that any different than the long board extending past the front end of the fence at the beginning of the cut? When you're in front pushing the board through, one can safely put a little lateral pressure against the fence. When you're pulling it out from the back, you can only grab it to pull when it's past the table edge and beyond the fence a little after that. A little sideways lateral pulling the wrong way and it's skewed. How is that any different than possible pressure variables applied to the board at the infeed side? When you're in front, you can push it onto an outfeed table. When you're in back, you're in front of the outfeed table aren't you? If you're pushing it from the side, it's more of an awkward motion. (and yes, I've done it before) Uh, so? Do you finish all of your cuts standing in the same place you started? I'll bet you don't. Think sheet goods. You'd be completely wrong. I do all my cutting from one position without moving around, but not for any of the reasons that you might consider. As well, this is all about control. Walking around while feeding (or pulling a board) through a tablesaw is increasing the chances for something unfortunate to happen. And yes, I know some do it all the time. Something else has occurred to me too. Considering the rotation direction of the blade, unless you're using an enclosed cabinet saw with a full dust cover over the blade, you're going be exposed to various bits of wood dust and splinters shooting up in your direction if you're at the back of the saw. shop, but I wouldn't have any problem with the process described. Does that make me an unsafe idiot? I don't think so (and no, you didn't imply that), but there are lots of operations that can be developed that while unfamiliar to some, are nonetheless safe and practical. Sure there are other methods that can be considered safe, but consider this. Tablesaws have been around for a long time. If pulling a board through a saw was comparably safe as pushing one through, there would be quite a few more people advocating it than there are. Until I hear from a number of those people, your single (so far) support for pulling from the back isn't going to cut it for me. No offence is intended against you with this statement. |

(I glue these under my seams in solid surface fabrication.) I make them longer that I need... then stop the saw. Pull out and cut to length. I always put my fence to the left of the blade..that way nothing gets pinched between the blade and the fence. |

The worse that would happen is a blunt force injury or damage to items in the shop from the resultant airborne missile. But no AMPUTATION. if the workpiece was short, I'd say there was danger of having your hands pulled into the blade in case of a kickback. but then, if the board was short, he wouldn't have had to go around and pull in the first place. ripping short boards is always risky. but this was a long board. with a long board, pulling from the back, you are far enough from the blade that the wood is gonna get pulled out of your hands first. second, he was using a featherboard. while I suppose it is possible to get a kickback with a featherboard, kickback prevention is one of the things that featherboards are designed to prevent. besides, where was it written that you gotta stand in a certain place only when you use a saw. where I'm SUPPOSED TO BE is where _I_ decide is safe/effective for the operation at hand. with appropriate stock control I stop feed and change position frequently with some operations and have for years with no AMPUTATIONs. |

Think yanking a tablecloth off a fully set table. -- Besides if you have the blade guard on, the chances of a kickback is less and if you're pulling from the back, the worse is you hands smashing into the blade guard. I don't want to push the piece into the blade guard since I don't have a clear vision under the guard. I guess we are assuming most of us don't use blade gards which includes me as well. I've been ripping long narrow (1/4" or less) this morning and pulling from the back - seems to me it's safer to pull from the back than push into the blade with only 1/4" or less clearance. But I could be wrong but lucky for 25 years. As far as pulling from the back I see contractors do that all the time even see them doing it on the home improvement shows. For long pieces I don't think I've seen a contractor pushing it all the way and a some point he is going to go around and pull it - it just seem like a natural process but again could be wrong technique. I wonder has anyone seen Norm pulling from the back? He doesn't use a blade guard either. |

Think yanking a tablecloth off a fully set table. -- Besides if you have the blade guard on, the chances of a kickback is less and if you're pulling from the back, the worse is you hands smashing into the blade guard. I don't want to push the piece into the blade guard since I don't have a clear vision under the guard. I guess we are assuming most of us don't use blade gards which includes me as well. I've been ripping long narrow (1/4" or less) this morning and pulling from the back - seems to me it's safer to pull from the back than push into the blade with only 1/4" or less clearance. But I could be wrong but lucky for 25 years. As far as pulling from the back I see contractors do that all the time even see them doing it on the home improvement shows. For long pieces I don't think I've seen a contractor pushing it all the way and a some point he is going to go around and pull it - it just seem like a natural process but again could be wrong technique. I wonder has anyone seen Norm pulling from the back? He doesn't use a blade guard either. One of the FEW kickbacks I've had on my Unisaw came within the first day or two of firing it up. The guard's plastic shield rested on the workpiece at an angle due to the narrowness of the piece and forced it to twist, resulting in a horrendous kickback. Right after that incident, after I evaluated why it happened, I removed the offending part. I rarely (not NEVER; just RARELY) use a splitter either. I can see where the blade is, and I keep my precious fingers WELL away from it. I use push blocks and push sticks. Good technique prevents kickbacks except for the case of relieved tension in a board that jambs it between the fence and blade. I'm not suggestion that YOU go sans guard. Just reporting how I prefer to run MY TS. YMMV. Dave |

I was doing this with some pine I was ripping down.
When I got to the core the wood was quite weak. The saw grabbed it and shot it across the room. Wow. I was surprised. But then again I was on the other side so my heart was hardly beating any faster. It did NOT suck me into the saw. This discussion is silly. People pull wood through tablesaws all the time. It is no less safe than pushing it. -j "LRod" wrote in message ...

Unlikely and not possible are two different things.
I think in the example given the operator had enough mechanical control over (from featherboards) the board that kickback would be very unlikely. But for now lets just look at pulling the board through in general. I agree that it's very unlikely that you'd be pulled into the saw horror movie style, however there is still a chance that the board could 'move' your hands towards or into the blade. I have seen the example of the Table cloth magic trick used many times in this discussion. Has anyone seen it done wrong, ever try it and sent mom's tuperware all over the kitchen? The cloth has to be pulled straight back for this to work. Your example of the jointer 'kickback' is the same, the jointer will push the board directly back. So the tablecloth analogy is applicable. In a tablesaw the board is also lifted and twisted during kickback (as compared to an ejection, where the board shoots back out of the saw). So the neither anolgy is really applicable. I think it would depend on many factors: like how far behind the blade you are holding the board, other safety equipment being used... Blah, blah, blah... What it comes down to is ensuring that we are safe at our saws. It's not enough to 'feel safe' and play the 'it's unlikely to happen game', we must ask ourselves two basic questions: Where are my fingers? & In which position do we have the most control of the work piece? Ultimatley if we control the work peice and don't run our fingers into the blade we should have a safe cut. There are lots of people that don't use splitter or guards that do it everyday.

Hand and arm go toward the body, blade in between. |

Seems like the consensus, if there is one, is this:
"If it feels safe to you, then it IS safe" I didn't feel safe making the cut the way I did, so I guess I will need to figure out a better way next time. For the record, it wasn't pulling the piece from the back that didn't feel right. I have pulled wood through numerous times before without feeling uncomfortable. It also wasn't ripping a board at 45d that didn't feel right. I have done this before with shorter but wider boards. It was the combination of everything that didn't feel right: Feather board close to blade Narrow board I couldn't use a push stick on Angled rip cut Board didn't hang off the edge of my outfeed table before I had to pull it So, next time I will have to do it differently so I feel safe.
