Smile Feed Direction

I just got a new router table which is a cast iron attachment to my table saw. Yesterday I was routing some 3/4" maple, making some moulding for a project and the router seemed to chatter as I fed it through. I have a 3.25 hp Triten router mounted underneath the table.
I was feeding from right to left as you face the router fence. Could I have been feeding the wood through too deep a setting? The wood was splintering and coming off in chunks. I was using a fence to hold the material against the router blade as I pushed it through.

I would be interested in advice to the those who have more miles on their router tables than I do.

Thanks Paul (Kelwing 2132)

HI Paul

It's a normal thing with some woods, try making smaller cuts to get to the profile you want to have.. the chattering sounds is a big tip off.

Hi Paul, you used these words

I was using a fence to hold the material against the router blade as I pushed it through.

I also was using a fence but not cutting the side next to the fence, but the other side. This caused the bit to hit the wood at the wrong place and very dangerous.

To sum up, the edge of the wood against the fence is the edge you are cutting.

Does this sound like what you were doing?????

There's nothing wrong with your set-up Paul, I have a Triton TR001 under my cast iron table and it's never failed to do what's asked of it. I agree with Bj that some woods do split easily especially if the cut is too deep and/or the bit is blunt and/or the feed is too fast.

Thanks, I wondered as well whether the cheap router bits? I will try a slower feed, and not bite off more than can be chewed so to speak. I am going in the right direction correct, feeding right to left facing the router? Thanks Paul

Hi Paul - also sounds a bit like you may have been feeding against the grain. You can get that if the grain is angled slightly toward the bit, ideally it should angle away from the bit. Sometimes you can do something about that and sometimes you can't. In the instances you can't, lighter cuts is usually the answer.

The problem with experience is I usually get it immediately after I need it.

Yes if I was looking down the piece of wood the fence is on the right and the blade is on the right. Today I was routing similar wood and one of the mistakes I discovered was I should have used a vertical fence yesterday. I added both a vertical fence today and tightened up my horizontal fence so the wood did not have any chance for movement. The routing went much smoother today, with a better final product. I did not look at the grain direction but will give it more careful attention before feeding it through next time. Today I passed about 10 to 15 passes as I was making 5/16" moulding. When ever I allowed the wood to move away from the router at an angle I could feel the chatter. In those instances I made a second pass and it corrected the imperfection. Thanks for your advice. Paul

To add another comment, I did try feeding through and only partially routing the profile I wanted, but finally I did the whole profile in one pass and with the fences and a slow steady speed I didn't have the chatter as yesterday. I did have some chipping but not as big of chuncks as I got yesterday. Thanks again. Paul

You have learned, grasshopper. I use a feather board to hold the piece on top and from the side away from the fence, too. Every little bit helps.

Cheers,
Roger
