Default Router Accident - Trying to understand what happened

Im not new to woodworking, and I think I understand what happened, but looking for more thoughts.

I had a table router accident last week.
1. I would like to share it in hopes that it can stop someone else from repeating it.
2. I want to ensure that I understand what might have happened

I want to start out with the fact that I take great pride in being safe, as I think we all do. But Im here to say that I misread what could happen. I now relate this as similar to a table saw kickback.

See attached pictures

I was doing a flush trim cut (.75 X 1.25 .5 Shaft flush trim bit) using inch hard board template. By the way, number 4 out of 4, so it was not the first one. The pine board was about 3 feet long with a 10 inch template at the right end of it. I was a couple inches into the cut, guiding the board with my right hand when all of a sudden the board flew to the right and the fingers of my left hand were in the router bit. The rest is history, including the ends of 2 fingers.

Its been a week now and I think that I figured out what might have happened.
1. I think that the board somehow road up off of the bearing and then dug-in big time and fast
2. I think that the fingers of my left hand may not have been behind the board, but resting on top of it holding it down.
3. The board launched from left to right like a bullet, so fast that my left hand did not react, but instead went with the board to the bit. Just like a kick back on a table saw.

Does this sound like what may have happened?

Thanks in advance for your help

I bet you never do that again!

Were you trying to take off to much wood ? Taking more than than an 1/8" off is a no no.

What you propose may have happened. The best way to prevent that is to make your set up better. Like adding handles to hold to the template or workpiece. Then your hand would have been behind the wood and could not have slipped off the wood.

Even if the wood did slip off the template and grab the wood you need to think about where your hands would be if something like that happened and build the safety into the jig, fixture or or even the table you are using.

The pictures are great to show my kids to remind them why never to touch dads tools.

I have cut my finger tip off on a table saw. 100% my fault doing something stupid. I can add some pictures as well, but I think yours tell the story well enough.

Not to be an ass, but this is 100% operator error as 99.9% of accidents are, IMHO.

I hope you heal fast.

I was taking < 1/8 off. I guess I never thought the router could pull a board like that, but when you think about it, 3hp at 25K rpms, it sure can. It goes to show that you must always have an escape route for your fingers. A better setup next time for sure. I think chucking the bit in a hand-held pluge router and stationary work piece.

Thanks for the quick reply, how long did your healing take?

Oh Man that has to hurt like all get out. I am sorry to read of your accident Darryl and hope things heal quickly. I know there is no sure fire way to prevent accidents, but it makes me understand why I use tools like my Grr...rippers so much. Next to the table saw, the router keeps my attention at attention.

Best of luck and thanks for sharing with us as a reminder.

I still feel it, I think about 6 months it took to totally grow a nail and everything, but I lost just the tip, you lost more. They sewed most of my tip back on. It was cut off halfway between the top and bottom of the finger nail. I think my tip grew back so well because my cut was straight. They just sewed it right back on the finger. The router probably cut your finger in a worse way were nothing could be used.

I feel bad for you, that hurts!

Sorry to hear of your accident Darryl. Do I take it from your posting that you only had one hand controlling the router? I always use both hands to control the router even if on the baseplate (as in sign routing) I always clamp the timber or if it is small enough use a router mat. I do hope it heals quickly for you and feel for your pain.

Excuse my ignorance I just re read the posting and it was on the router table, Sorry.

Damn. That is terrible. It looks like the guide bearing is too far down.
Push blocks. That's what you need to use. I've made several of them for uses like that.
Hope your fingers heal well.

Never, under any circumstances, combine a sleeping pill and a laxative on the same night.

1st: Sorry about the accident. Hope a good recovery & no restricted finger usage.

2nd: Thanks for posting the accident.
Very good reminder to keep everyone on their toes that working with routers (as well as other tools) can be dangerous.
I'm new to routers so this is a real good "this can happen" scenario.

I made this for free hand cuts just cause I got nervous being close to the bits.
Got the idea from one of bj3 jigs.
Don't know if this would have helped, but maybe. (bottom pics)

Again
Thanks & hope all heals well.
