I did some 3 x 5 - 20' and 28' pine a couple weeks ago. NEVER going to do that again without an extension. Got them done, but did not charge near enough for the job.

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.

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

@POSTON WIDEHEAD - Instead of trying to get the 21' log through a 13' door, why didn't you move the mill outside? 

Either way, great job on gettin' 'er done! 
There are no problems; only solutions we haven't found yet.

Once it's all set up it is quite amazing, I agree.  As long as the customer can remove the 30 ft 8x10!!
I've had some jobs like that.

I've also had some emails where I ask whether you can remove the 8x10 after I saw it.  No answer.

What in the world is a 60' beam used for?

In my case (56') I'm doing it for the challenge ::)  I have my ridge, 2 mid-span and 2 wall beams that run the length of my cabin, spanning 4 bays.  They are all visible when done.  I do have my plans drawn with them spliced halfway.  But, I've got some trees and a mill that should do it.  I'll start with the biggest and if the cuts go wonky, I can trim it down.  Worst case, I have to splice two for the length like the plan says.  If I can pull it off, people will look up 38' to the ridge and say, how the heck did you do that?

That's the first 60' 12x12 across the top backside of the 2 log cribs. We made another for this near side. There were 4 cross beams mortise and tenoned in between to make a rigid flat frame to tie everything together and launch the roofs from. The beam was sized for 20' spans, which are its bearing points. There are 3 other similar length runs of beams in the barn that are scarfed. Finding a tree big enough is a small part of the problem! We 3 sided them in the woods, lightening them but leaving them strong, then did the last rip at the barn. We pushed the third rip off of one in the woods and I could have laid my arm in the rotten spot. We used it for smaller stuff but that was a bad day. All the logs below are slabbed on 2 sides, they are 20 and 30'. The short ones we did on the Lucas the longer stuff was with the Alaskan. By hopping that straight plank down the tree there is really no limit to length.


Edit, here's another shot. Both 60'ers are in up top, the straps pulling the cross beam joinery together are showing. The lower run of beams is scarfed, there is a ~20'and40' in those plates.

Great answer for what you do with a 60'.

I have to mention my first 22' pine with plenty of rails for my LT-10 went smooth and then I marveled in the length...then cut in half and put on my trailer :)

Always good to focus on the entire job when taking big logs...ha ha

Great job!

Don,
    Do you have a thread about this twin crib log build?  I would love to follow it if you did.

Sure, I was getting ready to go find it and add a pic, hang on.

I did 2 beams of 25 ft X 8x8 on my mill . Mill is only designed for 16' . . I did my four cuts to get my 8x8 square. Cutting of the slabs with chain saw each time. I then moved the log back wards on the mill to get to tha last 9 ft round section . I placed 2" blocking on the bunks . This lifted the squared section up 2" and made sure the round uncut section was not touching the bunks. I then tapped a small wedge under the uncut end to take out any droop . Then made the last four cuts . Good to go . In theory  I could cut any length using this method . I have hatches on each end of my mill shed that let me pull long logs in through one end and out through the other .

Where there's a will - there's a way.
I surprised though, Quebecnewf - you found logs that were 12" at the small end of a 25 footer, in your part of Canada ? 
Those trees must've been hiding from the logger for many decades!
