Default Climbing, climb cutting

Climbing,or climb cutting is a situation in which the direction of rotation of the cutter in contact with the wood is the same as the direction of movement of the wood. This dituation is very dangerous unless the wood (or whatever material is being cut) is very tightly held in place. Climb cutting can yield cleaner edges that normal cutting. In general climb cutting should be avoided. Climb cutting situations can arise from lack of attention or thought or unclear thought.

This post was intended to be a "discuss this term" in the Word Glossary". On the other hand, it might have a potential for starting a lively discussion.

Tom,

"In general climb cutting should be avoided. Climb cutting situations can arise from lack of attention or thought or unclear thought."

I agree, every time I pick up a router for hand held work, I really have to think about which way to move the router.

Good one! But remember, that is for hand held routing. Table mounted is just the opposite.

"Feed as you read" only works if you are reading the outside of the book.

Still, I like it. It's better than my technique. I think of how I do it on the table and invert it for hand-held. I'll be using your system. Thanks!

Check out that new high-tech cordless router.. wireless and no recharging required!!

I use the rule for plunge/hand routers, push it away on the inside pass pull it to you,on the climb cut that I use all the time if I have stock that likes to rip/chip out I do just the opposite but with very light cuts.
" climb cut) The bit will push the stock back into the cut..and keep it from ripping out.......great on the end grain...

Look at "bump cutting" by Charles Neil on U Tube. It really works well.

George and Jim,
Correct. I should have added that, when confused, I envision myself hand routing in front of the router - standing inside the template controlling the router when routing the inside of templates, etc. The direction when table routing has always been intuitive to me but you could envision yourself standing on your head.

"standing on your head' - now I am confused.......
I just have to remember Gary Rogowsiki routing a mirror frame...

Hi Ho: Sommerfeld has a neat gadget that is a combination guard and featherboard. He uses it to cut grooves in plywood where tearout would be a problem. The thing provides enough pressure on the router table so that the work piece is trapped and can't be ejected even when climb cutting.

If you want more info, go to his website (the thing is on the cover of the latest catalog) at Sommerfeld's Tools For Wood

I haven't used the thing, but have seen him use it on a DVD.

Let us know what you think. I'm sure some of you have one.

Dirk
