planer / planing question
Hey All,
First, this did not happen to me but while I was planing some oak boards today I was pondering this scenario; What would occur if you ran a tapered board through a thickness planer, thin end first, and the thicker end was greater than the maximum cutting cappacity of the cutterhead? Would the board become stopped by the front edge of the planer so it could not be presented to the feed rollers and then cutterhead? Thanks in advance. Marc |

planer / planing question
The board would be wedged between the infeed table and front edge of
the planer. Howerver, I would not recommend proving the theory. Next time you're plaining, and need to ponder...how about solutions to world peace?

planer / planing question
The planer will start to bog down and eventually stop. Depending on the
drive system you might have some smoking belts or you might throw a circuit on the machine or at the source. I've done all three ;^) marc rosen wrote: Hey All, First, this did not happen to me but while I was planing some oak boards today I was pondering this scenario; What would occur if you ran a tapered board through a thickness planer, thin end first, and the thicker end was greater than the maximum cutting cappacity of the cutterhead?

planer / planing question
Yes, the machine has a maximum thickness which can be removed. If the board
presents more than the design, then the board will stop. The rollers will spin, and the blades or rollers will likely cause burn marks. The machine may begin to overheat and may eventually trip the breaker, or burn some sensitive elements in the machine. So, it pays to review the entire length of the board to determine the planer setting. Dave Paine. "marc rosen" wrote in message oups.com...

planer / planing question
I have two planers and neither will bog down or smoke belts the drive
rollers just slip and you can reset(cranker open) more if the bed locks are not set. On the big one with steel drive rollers there is no damage but the small one with rubber drive rollers takes a beating(drive rollers get ripped, torn worn depending on how rough the lumber is.

planer / planing question
I'll often stand with my hand on the wheel when I have an iffy board.

You got it, something I learned the hard way

I've done all three ;^) Been there, done that, got the t-shirt. It's not pretty. It was a learning experience. I now set the planer with respect to the max thickness of the board and go from there. |

Would the board become stopped by the front edge of the planer so it could not be presented to the feed rollers and then cutterhead? I thought all planers had some depth-of-cut limiter on the infeed side of the case. Means the board will never make it to the cutterhead, but catch outside. One possible fix for this is to raise the cutter (lower the bed) if the board encounters the feed limiter. Not that I've ever pushed my luck and had to do it of course. If you get a couple of dog boards you may find it easier to saw a bit off either end than keep feeding the planer. |

planer / planing question
It does happen.
When I was running my store I had sold a customer a Jet 15" Planer. I believe that this unit had about a maxium height/thickness of six inches. The customer had the unit opened to maxium cut and was feeding a 6 X 6 22 foot white oak barn beam through the unit. Only thing was the beam was tapered and when the beam got about half way through, no more room and the beam was hung up tight! My customer called me and I went out to see if and how I could help. The beam was a special order beam and very expensive, so No cutting the beam out. The beam would not go in because of the taper and would noy come ourt because of the kick back fingers! Ended up taking the planer apart. What a job! Worked out Ok was able to save the beam and the planer. Customer finished the beam with a new Hitachi electric hand plane that I sold him Mike .
