I was wondering if some one new why my wood keeps tearing out. I'm cutting a pattern with a bell on the bottom, just a part c-shape. I band saw it with in a 1/16 or so from the line & almost everytime my router would tear out the one part. I have a bosch router so I can control the speed & I lowered it some. No dice! I even made a new leg & put the jig not parralell to the grains. Nadda. Using hard maple 4/4. Really need some advice on this.
thanks, Bob

Hi Bob,
You may want to slow feed of router movement and raise the actual RPM of the bit. Cut convention may also help you out (Climb vs. Conventional). A Climb cut (usually used in hardwoods, grainy materials) would be cutting a finished edge by climbing with the cutting edge of tool. A conventional cut would be cutting a finished edge with the tool spinning away from edge, on the front side as cutter moves along. I hope this info. has been helpful.

tear out
Your saying to increase the rpm on the router & slow feed the wood? I always thought you slow both down. I put a new bit on there too. It helped.

tear out
I wish I has a CNC router. No..just old fashion hand feed routing. But, thanks anyway.

Make sure you are not trying to take off too much in one pass. You can also make a short starter cut on the \"wrong end\", then make the cut from the other end so you don't have to end up off the piece.
To clarify, you have a work piece say 24\" long. The \"correct\" cut direction with the router is A-B and you get tearout on the B end. Make a short (2 or 3\") cut on the B end with the router going in the B-A direction then start at the A end and make your normal A-B cut. Since you have already cut the B end, there is norhing to tear out.
Hope this helps.
