About a week or so ago I was ripping a 2X4 block into a 1X2 on the table saw and was using a plastic pusher stick that came with my Bosch table saw. I really like the feel of the pusher stick as it is heavy and fits my hand. Apparently as the block was leaving the saw blade, I angled the pusher to keep it tight against the fence and the blade caught the push stick.

The pusher exploded in my hand, putting a gash in my palm that required 7 stitches. The fact I am on blood thinners didn't help the situation either. It wasn't squirting ,just seeping and soaking.

Later upon examining the pusher stick it looks like my assumption was right in having twisted the pusher into the blade. The block didn't kick back and showed no sign of the mishap. It looked like the blade melted the plastic and welded to it for a second by the cut in the pusher. I wonder if a wooden pusher would have faired better? I am certain a wooden one would not have exploded.



Here are some pictures to give you an idea of what I am talking about.

Sorry to hear about the accident, hope that it heals quickly. I have a plastic pusher made by, I think CMT, but it's solid from the handle down with no holes. I've nudged the blade with it a couple of times pushing parts that were barely wider than the stick and just have a worn spot on the end. You were lucky, the pieces could have flown up and hit you in the face.

Herb - sorry about the accident - it could have been much worse - if your pressure had been greater you would have pushed your hand right into the blade.

That style of pusher is, in my opinion, one of the worst designs as far as safety is concerned. All the pressure is at the rear of the stock - easy to skew the work piece sideways causing kickback. Pressure needs to be applied downward along more of the work piece as it goes through. This style is much better but if you want real safety, go with the GRRPipper - money well spent.

Sorry about your hand Herb. I make my own push sticks from 3/4" plywood scraps. They are similar to the shape of your plastic one. If I am ripping something narrower than 3/4 the push stick gets a kerf (why doesn't spell check accept that spelling of kerf?) in it. When it gets chewed up I make another. Usually there are 3 or 4 laying around the shop

GRRPipper is $ well spent, I also am in love with feather boards to hold stock.

Sorry about your accident!

Geez, Herb...that had to hurt. Get better quick, eh!
You probably should let Bosch know that in a crunch their push-stick design is more of a threat than a safety device(?).
(If they offer to replace the push-stick you'll know they aren't clear on the message. )

Sorry to hear it Herb. It is interesting as I just bought a GRRRipper off eBay for $45. Never used one before but maybe it will save me. I think I will avoid any plastic push sticks like the Bosch you had.

I agree with Dan, send Bosch the pictures. They may want to change the design or at least issue a warning about letting the blade contact it.

I like to make pushers similar to what Vince is showing except out of 1/4 to 3/8 ply. You cut it out so that there is a 1/4" or so hook left at the back of the bottom like the heel on a shoe. Since it's home made and usually out of scrap it doesn't hurt your feelings if you nick it. And you can usually cut a new heel a few times before it needs to be tossed.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Well you weren't kidding about it exploding! Now Herb, please be careful in the future and use a second stick to push the wood into the fence. Then you won't have to angle the single pushstick.

I hope the gash heals quickly, although as you're on the thinners, it may take a little longer going on evidence from my S/O who get's bruises at work that takes weeks to go away.
