Sawing my first 21 foot beams.
« on: July 20, 2013, 09:32:43 PM »
I've got a customer who brought in 5, 22 foot logs....today. They were old Pine, crooked and the bark falling off.
He wants 21 foot beams to go in his new house.

Now get this.....he wants his beams 3" x 5" x 21 feet.  :o

After a long talk, I convinced him his logs were to small in diameter and too crooked to saw.

So off to the woods I go and get 5, 22 foot logs (I fell them) and bring them to the mill.
I'm telling this guy, this 3 x 5 x 21 green beam will most likely crown or sag at this span. So he said he would put some legs under it while the beam dried.

Ok.....I did my best and this is now his problem.

Now my problem.....getting a 22 foot beam through a 13 foot door.  >:(  I did it.....after a while with my trusty backhoe.
Now, I get the log on the mill and low and behold I find out I can't saw a 22 foot log log.
So I saw the length down to 21'-1". Now I find out I still can't saw it.
So I take the rubber bumpers off.....and get the log just right and it will saw it now but JUST barely.

Now....I was under the impression I could saw at least a 21 footer without taking the bumpers off......but I guess I was wrong. But it is no big deal. I'm sawing 21 foot beams now and have 4 more to do.
So I guess all is well as long as I remember where I laid my bumpers.  :)

In the last pic, you will see where the head stops and the blade teeth just barely make it through.
I can promise you this job is paying good.....but it's a little tough when you're by yourself.

My first mill was 21'-0" from "tooth to tooth". In other words, the teeth are touching the end of the log where I start, and just get to the end when I finish, but the blade doesn't clear the end of the log.

My present mill was 21'-1/8" (before I added extensions).

Taking the front bumper off helps, but watch you don't sheer off that Nylon bolt that holds the contact strip in place -- the shoe will hit it if you bang the carriage into the bumper bracket. You can also pick up an extra inch or two if you take off the back bumper AND add a couple of links of drive chain so you can pull the chain adjuster back a little.

David Customsawyer taught me the best way around the overhang problem.If it's much overhang support it.When you get almost to the end of your track just hit the up leaver and continue sawing out of the cut.Finish 3 sides before you move the cant.I'm assuming you have roller toe boards.Good luck.

Nothing like a real challenge. Did I not read an earlier post that someone mentioned sawing on raised toe boards and pushing the log back to the front (actually pushing the log through the blade)? Since I have never sawed a 21'er I assumed that was the actual distance from bumper to bumper. Guess that's what I get for "summin".   :-\
Since I retired I really like work: It fascinates me. I can sit and look at it for hours.

Glad you posted that.  I didn't think it would not be quite that much pain to saw a 21' log, but I guess you have to cap the capacity somewhere when designing a machine. Needless to say I never sawed anything that long.
It's the going that counts not the distance!

just a guess, it's probably designed to cut 20' lumber with some room to spare.  :)

Yes Slider I do have the roller toe boards and thank goodness for that. Even then trying to roll a 21 foot log can make you scratch your head if a knot has to roll across the roller.
I would not have taken this job, just because of my shed set up but the customer could not find anyone else with a band mill to do it.
At least I've learned a few things with out tearing something up.....yet!  :D

Same here, when my sawhead is at the front of the mill, I can mark where the teeth are and then run the sawhead to the other end and the teeth have a total travel of just over 21', maybe by a quarter inch.

However the body of the blade is still "in the log".

I did some by putting the log on skids to allow the log to be moved back and forth on the mill bed on the same plane. It was hard work, required moving the log up and back on each cut.  If it was a regular thing, I would just add on another bed extension.

This is correct Chuck.

Actually in the booklet they say maximum log length 21'.  I guess they really mean that.

On my business card I claim I can do 20'-6" with the mill and 26'-6" with the 6' extension bed.  I have done 20'-8" but it was very tight.  Not I did not remove the bumpers.
When sawing timbers that long plan on supporting the ends or it could droop, and if you take pride in your work, you will not be happy as thick and thin will come into play.  Gerald

Last summer I sawed out two 5" x 11" x 21' ash wagon sills to replace the ones that broke. Careful placement of the log and square cut ends are essential. Also having your Wheaties for breakfast.  ;D I may have to cut 4 more plus deck boards this summer for 2 more hay wagons.

I was asked a couple months ago to cut some 6" x 6" Eastern White Cedar timbers 22' long.  The customer wanted six of them at least 22'.  Finding them that long was the hard part.  My father has a cedar bush that hasn't been cut in the last 50 years so I found the six trees I needed (about 150 years old).  One of them was 9" across at 25'.  That's quite good for cedar in these parts.

From what I am reading, I think I used a slightly different method.  I cut as far as the mill would cut.  Then I stopped and backed up the head a foot or so (with wedges under the slab) and cut the slab off with a chainsaw.  This left me with a couple feet of uncut log.  Leaving that I would then rotate 180 degrees and do the same.  Then I would pull the log back, finish the last couple feet, rotate 180 degrees and finish the last couple feet.  Rotate 90 degrees and repeat the process again.  I did this so that I would always have a flat side sliding back on the deck.  Admittedly cedar is reasonably light and in this case small diameter.  I'm not sure how I would handle things if the log was larger diameter.

The max on my mill is 22'7" if the log isnt very wide. Since my head is angled, I lose distance with width. With a 16" square my max would probably be around 22'2"
