Interesting bench!  It's called a "three log bench" so...  three logs is probably important.  But there's no minimum width for the bench (at this moment).  

So I'd say that if you take one seat log away, and if you can show that the three logs are peeled, I think it qualifies.  As the BB is currently written...  Thanks for finding a spot where we can make the BB more robust!

I'll be editing the BB to state a new requirement for minimum seat width so that we get beefy logs in the future.  Yours will be grandfathered in if you resubmit in the next week.

Well, OK. If the requirements included peeled logs all along, I totally missed that and left the birch log unpeeled. So I went out and peeled it and removed one of the seat-pieces. I have mixed feelings about grandfathering in. It’s not my goal to cheat or exploit and I specifically thought using one of the 6-8” logs felled in the earlier BBs was the point. But I guess I’ve decided I’m ok with it since I’m here posting pictures.

Is the expectation for these benches that you use more than half the long log’s depth, rather than splitting it in half the way I did? I’m trying to understand the newly added measures — 11” log and only 6” bench.

Thanks for peeling it, that was in the requirements all along...

The idea for the bench size requirements is to make sure the log is beefy enough.  The narrower seat allowance is in case you can't carve it down in half due to the geometry of your logs.   A 20" log with a 6" seat is ok, an 11" log with a 6" seat is ok, a 6" log with a 6" seat may be kinda weak.

I made a 3 log bench! It's quite large. I received some assistance with lifting it into place, but I did everything else myself. I split the log with a chainsaw. I used a chainsaw to cut notches into the legs, which I then chiseled out to make a saddle joint. The first two legs I cut were too short, so I had to cut some new ones. It was mostly smooth after being split, but I did a bit of hewing on the rougher bits. Once I was done, I laid down on it and relaxed a bit, because this was exhausting!

Edit: I realized I forgot a photo of the width, so I've just added one.

I'm currently at the BB20 event at Wheaton Labs, and I'll be leaving soon. I would greatly appreciate if anyone who's qualified could review my submission, so that I could fix any potential issues before I go. If no one is available that's fine. Thanks very much!

My first 3logs bench. Using a dead tree, but next time for the straw badge i'll use a fresh tree for the 3x 3logs bench. Already looking forward to bring friens and try it

Here is my BB submission for the 3-log bench. One of the projects I'm proudest of so far, I think.

Here are the pictures I've attached:

 - My three log chunks I started with
 - your three log chunks shaped (one pic of the bottom logs, one of the split seat)
 - final product showing length, height and seating surface width

Since my pictures showing the measurements of the final project don't really give a clear view of the finished bench, I've added one of myself smoothing out the last rough bits with a plane so you can see the bench assembled and operational.

My suburban restrictions made this BB a little interesting to accomplish.  I had to get in touch with an arborist to obtain logs (because I am broke and can't afford to buy from a mill).  Then I had to haul them home from the next town over, and this silver maple log I used for the bench is no small piece of wood.  At 11 feet long and about 12 inches in diameter this log was not easy for my friend and I to get home.

I used a chainsaw to cut off two two foot pieces for the base logs of the bench leaving just over seven feet for the seat.  I also used the chainsaw to rip the seven foot section down the middle for the seat.  As you can see it was not the best rip and required some hewing with hatchet, draw knife and plane.  The pieces were then peeled.  Finally, I scribed and chopped the saddle notches into the seat using a hatchet.  I took the whole mess to its final location and put it together.

Three log benchs are a great use of wood. Whether you're by the camp fire or looking at a spectacular view you won't regret the final result
