In the Goat pen.

I nearly think this post should be a sticky.

One of the things I learned at the Sycamore Project was that I needed a bigger chainsaw bar to more conveniently split big logs in half.  For quartersawing, bigger logs is better, and around here, once they get real big, their price goes down because the big mills don't want to mess with them.  So bigger logs for less money means I needed to learn some tricks of splitting logs.  Customsawyer did a great demo ripping a log in half, so it inspired me to get a bigger bar. 

After many, many phone calls I finally located a 52 inch Forester bar. 
Here is the long bar, mounted on the saw, resting on the BushHog, and it seems to do real well so far.



Here is also the latest load of quartersawn wood straight from the kiln, about to be dead stacked, for its trip to the planer.  About 3,500 board feet, give or take, some boards more than 16 inches wide.  The owner of the commercial wood millwright shop that does the planing told me that he had not seen quartersawn wood that wide in decades and everybody was talking about it at the shop.

That should do the job, 8) 8)

I split this one with a 60 cc saw and a 24" bar.  It took a little work with wedges and a maul to finish the job.

 

I got some 22 inch wide boards out of each quarter.

Wow.  Sweet!
I wonder if that blade comes with an optional truss and directions to the chiropractor ...

Just lay the bar and chain on the log and it'll do the work.  Have fun!

I am going to have to work some more on the finer points of reverse roll quartersawing  :D

That happens to me too often, quarter sawing or not.

Danny,

   I never do things like that - unless there is a big audience.

[paul case]

I thought you was gona talk about reverse roll quarter sawing and here is Danny setting up his skateboard/bicycle ramp on the tire of his sawmill. Obviously he has been grinding that ramp a lot to have the edges all smoothed off at such angles so you know this isn't the first time. ;D ;D ;D

I have had a request from a landowner that we are now logging on, for 800 bdft of q sawn lumber from his post oak trees. They have quite a few that are pretty nice and I hate wasting much of them, so i devised a plan. The logs are big. I think we will be able to saw out a 23'' cant without too much bark on the corners. Then we will saw a 7x9 tie out of the heart leaving 4 pieces that should yield 50% quarter sawn material and the other 50% will be grade,some of which will need edged. I realize that the q sawn stuff will not be perfect, but will yield edged boards that are 6''to 8'' wide.

[YellowHammer]

Well, it was looking good up until then. :D

[Darrel]

I looked across the mill at the other tire to make sure there wasn't another ramp over there. :D

oops.....

[4x4American]

I hate it when that happens :D




Hey I have a public service announcement to all you pith measurers..I noticed at the project I was at two years ago that yawl measure the pith from the bed up to it to level it.  We all know that the log aint never in the perfect spot to do that and sometimes its hard to get an accurate reading.  So I'll just share what I like to do, it might add an extra second to the front end but it takes two off the back end and is more accurate.  I bring the head up high enough to clear the whole log front to back, and drive the sawhead over each end of the log and measure down from the blade to the pith to get it level.  Obviously make sure you don't move the head up or down, keep it at say 34" for example. On the WM mills you can slightly adjust the head to being perfectly over the pith if you over/undershoot it.  I just hook the tape to the back of the blade and measure down.  If the log is too big to drive the head over then u gotta eyeba it and trim it first then adjust it or just do it from the bed.

4x4, that's how I do it.

I invented it go away!!  lol

[Ljohnsaw]

I just lay a 4 foot level across my rails and measure up from that.  I can do that anywhere.

[kelLOGg]

I use two T-rulers, one at each end of the mill. See reply #7 in https://forestryforum.com/board/index.php/topic,52765.msg761559.html#msg761559

I guess that I am just a Southern Pith Measurer  .   

[Magicman]

It is a pithy job.   :

Hey, you're the one That made the public service announcement. I was just keeping it all to myself.  ;D
