I have decided to try to make tenons on my router table. For practice,
I used some pine I had lying around. I found that I got great deal of
tear-out when the bit was leaving the workpiece.
I'm new to the finer points of WW, so I ask your advice. What are the
possible causes for this tear-out? What can I do to avoid it in the
Also, is this specific to pine, or can I expect this type of problem
with oak, maple, etc.?
Thank you for your help!
It can happen with any wood. Three possible things to do.
Take smaller cuts (helps, but not a 100% cure)
Cut the backend in a little, then complete the cut in the proper direction.
Put a scrap piece against the back and let that chip out.
#3 is probably the best.
Try wrapping the wood with masking tape, such that cutting the tenon
removes some of the tape but leaves most of it. Wrap tight, and only
one layer (put the gap in the middle of one of the cheeks). This
should reduce the tear-out somewhat. However, a backing piece should
also be used.
It happens with many types of wood.
Another option is to score the wood with a knife before routing. If
you can get the score on the right spot, it may help.
