Duck and run! A circle sawyer initiation.
« on: August 03, 2004, 07:35:58 PM »
Ya know how the bandmill guys say ya ain't a sawyer till ya hit the mill?  Well Not sure thats the case with a circle mill.  :D  Our forest tech, and back-up sawyer was sawing for earl, the sawyer at our west mill today. Something went way wrong as you can see by the pictures. The board piler was even hit by shrapnel but luckily was not cut or injured. There is metal all over that building. Only 17 shoulders remain after cutting over two inches into the head block after first sawing through a dog.  This headblock did not even have the log on it! The log was on the first two and this was the last.  Jake came to me first after it happened still visibly shaken. He had no clue what happened. I went down and from looking at the lumber leading to the accident,  the the cant remaining on the bunks, and the damage, I think it was an equipment failure and not human error. It looks like the back dog inadvertently came to the out position while the others were in. He hit that back dog full force and this sucked what was left of the saw into the bunk. NASTY!! It could have been much worse though... He coulda been filling in for me! :D  He will be, starting tomorrow and through next week. Am I worried? Hell no. He will be so gun shy that he probably wont get much lumber cut.

  Somebody was looking out for the people involved with that mess. I'm glad to hear that no one was hurt . The only thing that hurts is your  bosses wallet . A picture is worth alot to show the sheer power that the sawmill has . I second the thought about the racket it had to have made .  

Is it a requirement that you keep clean drawers in your  truck when you go to work . Cause I'm pretty sure someone prrobably needed  clean ones after that wreck .

Those log bunks you are looking at are at least half in steel plate.

I've had 2 of those this year.  The one wasn't too bad, but the other was major.

The first one happened when a limit switch failed.  Human error?  Partially.  I was watching someone else to make sure that a tie wasn't going to give them a problem.  I was coming back, but had inadvertently pushed my headblocks front instead of back.  I pulled the board splitter into the saw and sawed off a bottom dog.  

Damage - broken windshield, holes in the roof, and lost 1 shoulder.  Up and running in 1/2 hour.  Limit switches are still on, but have also put on mechanical stops.  Won't happen again.

The second one happened when a short piece of log taper ran behind the board splitter.  The off bearer kept on pulling and turned it sideways, pushing the saw into the carriage.  Lots of banging and clanging.

Damage - saw had 14 lost or damaged shoulders.  Now junk.  The nut on the mandrel was stripped.  We had to cut that off.  We had a spare mandrel, which had to be replaced.  Downtime was about a day.  Damage - several $1000.

Solution to this problem is to have the butt end toward the front of the mill instead of the rear.  

You need one of these every once in a while to keep you humble.   :D

Holy cow! :o I jump a foot when I break a bandmill blade, I'd need a change of pants too if I'd been around when that happened. Is the blade ruined or can you salvage it?

Glad to hear nobody was hurt. :)

I'm going to disagree strongly with that one. :)  My last one was my first one 22-23 years ago and I hope it stays the last one.

That blade looks like it is destined to hang on a wall or a sign post after a plasma torch has cut a fancy picture in it.

When I picked up my Woodmizer the tech who trained me told me that sooner or later everyone wil saw into the side supports even if only to nick them.

He told me of the time a local Indianapolis TV station sent a reporter and camera man to do a local business feature story on Woodmizer. Don L. who was one of the founders of the company was doing a sawing demo for the story and with the camera rolling and the reporter next to him he sawed into the side supports. It made such a noise the reporter dropped her microphone and both she and the camera man took off running for safety.  :o  :o

After they convinced the reporter and camera man  the sawmill had not exploded, they got them back to redo the story. Don told them that he always did think that those side supports were too long.   ::)  :-[

I think most of us are running close to the same RPM on the blade. Mine is a little fast at 600 RPM. At that speed with a 52" blade the outer rim is turning around 9000 feet per minute. You figure if the blade could hit the ground at that speed it would go almost 2 miles in one minute. With a lot of power and that speed it don't need teeth to cut most anything. I know I have some nice cut marks in my dogs. They are half inch to.

I'm running 690 RPM and a 54" saw.  We'll probably buy a new saw in the fall.  I'm just hoping the price of steel hasn't gone up too much.

We get shoulders welded back on the saws for $75.  Sometimes they're good, sometimes not.
