Add one horizontal log to berm/hugelkultur scaffolding - PEP BB roundwood.sand.scaffolding

Here is my submission for adding one horizontal log to a berm/hugelkultur scaffolding - PEP BB roundwood.sand.scaffolding

To get certified for this BB, I am posting pics of:  

 - chunks of wood I started with
 - Action pic about half way through
 - Final product
 - Indication of the strength and stability of the scaffold log.  

Here's my submission for this BB. I added a horizontal log to a hugelkultur scaffolding at Wheaton Labs during SKIP last summer.

The photos I have from this project show:

 - My chunks of wood that I started with
 - Process pic about half way through
 - Final product, including me standing on it to indicate its strength and stability

 - Your chunks of wood that you are starting with
 - Action pic about half way through
 - Final product
 - Indication of the strength and stability of the scaffold log.  Examples could include:
    - You standing on your log
    - You and some friends sitting on your log
    - Creative alternatives?

I was with a group adding vertical logs to the hugel near the Fischer Price house at Wheaton labs. That's why you will see lots of materials and additional notches being made as there was 3 of us working at the same time.

Final product & Me jumping on log:

I used spruce and cottonwood for these support logs. I made corner flat joints (shoulder joint, I think they've been called?) Dez showed them to me for rockjacks. I did sink some bolts into them to keep the horizontal log from rolling off.

I put up a new horizontal log on the hugel scaffold in front of Allerton Abbey.  Behold!

I've never done mortise and tenon construction like this before and I was so impressed by how well it turned out -- stable and level. An existing horizontal log was removed because it wasn't structurally sound, so I cut in a new location on both vertical logs to install the new horizontal scaffold.

The photos I have from this project show:

Attachment 2 - Process pic about half way through, the horizontal log I worked a tenon joint into is in the background while I'm cutting in a new mortise in the foreground
Attachment 3 - Final product, including me doing a standing balance on it to indicate its strength and stability

Brought some muscle into the woods with me today to help maneuver some logs for my scaffolding.

I started adding some scaffolding to the hugel project at my place documented here: https://permies.com/t/269642/Hand-built-hugelkultur-frog-pond#3735660

The two uprights were from the big fallen pecan tree and the horizontal is a piece of old black cherry heartwood that has been in my backyard for at least a decade and is still solid as a rock and heavy. First time doing this and didn't spend very much time looking at examples here so my initial effort was a bit in the wrong direction. I instinctively cut the first notch in the vertical log aiming for a plumb cut, this led to the rest of the task being awkward. I had to cut the first side of the cherry log fully into a tenon in order to fit the mortise angle. With it temporarily in place I was able to mark out for the next mortise and saddle joint on the other vertical but it was a fussy affair. Lots of up and down with a heavy log to get it trimmed to fit. All hand tools, saw mallet chisel. I think these definitely will improve the steep hugel. Future ones should go smoother.
