Default Dangerous Occurrence - anyone else experienced this

Dear All

I was happily routing, using my cutter to cut a piece of pine for a cupboard door, Cutting across the grain,making a nice finish; this was the second piece. I cut from both side, using a fence, - when I reached the end of the cut in the middle, the off-cut (10 x 22 cms) flew from the router, across the room and smashed into the wall, at high speed. I lurched forward, but did not fall (fortunately).

I had been using the router for a few hours, had made numerous cuts, but the wood took off and could have seriously injured someone. The router was a TRA001 using a small cutter at high speed.

As it is I have a hole in my wall and no idea what I did wrong, but am seriously worried.


Help very much appreciated

Paul

Sounds like you may have cocked the piece. Just a slight variance would cause it.
Can you use a miter gauge with a hold down clamp attached? Or a sled with a hold down clamp will work well, if you have no slot for a miter gauge.

Paul, not sure what you were doing. As I understand it, you were cutting 1 board into 2 pieces with one of the pieces between the bit and the fence? If so, that is a recipe for disaster, especially if you were climb cutting it!

I have found that hand tools are the best choice when I want to make mistakes at a slower rate of speed.

I don't suffer from insanity. I enjoy every minute of it.

I am with Duane, it sounds like you were using a router table as a saw. A table saw or band saw would be more appropriate for this type of cut.

I am not very experienced but sometime knots in the wood could do the damage

+1 with Duane and Mike. Sounds like you trapped a piece between the bit and fence.

+1 w/ Duane.

Do not cut a piece of wood with a router table. That is just not what it was designed for. Besides it wasting mass amounts of wood by a wide kerf that would tend to wander without a fence, doing it slowly because... I have to say it-- That is just a downright dangerous!!! I was going to go into detail, but why? A router's intended designed strength is in the capability of creating a "profile"... not in cutting wood into pieces. There are tools designed for that.

Kickback. Trapping an "unsupported" piece of wood between a bit's cutting surface spinning at 24,000 rpm and a fence... The math tells me that potentially with a 3/4" bit, that piece could reach 321 miles per hour. Another danger is breaking the bit and pieces flying at that speed.

I'm sorry. I'm fairly open minded and imaginative... And I see no version of that where cutting wood and trapping the unsupported offpiece between the bit and fence comes out with a good outcome. The risks greatly outweigh any inkling of any imagined benefit from that.

Wow. Scary. I am thankful that you (or anyone else) were not hurt in this education.

EDIT-- My realization with that... makes review other things I do and think is okay... Always good to err on safety.

I do have a question.

I use to see a decretive template/bitt set advertised in the wood magazines, that was a jumping dolphin routed into the wood face. I'd like to find that set. Any suggestions?

I'm a retired merchant marine captain. Never been so busy in my life. Retirement gives you way to many choices. I'm setting up a wood shop for myself primarily to do work on my personal boat, a 50' John Sampson design sloop. A lot of that work will be with routers.

Now I gotta get to work. Hope to get some help with the template/bitt set and best regards.

Thanks to all for the advice and telling off. It seemed a good shortcut as not only did I get an accurate cut but a good finish all in one go. I see now that it was a stupid idea and to be honest, after that happened I went back to my saw, so I hope any other beginners read this and don't use the router in this way.

Still have a hole in my wall!

Regards

Paul
