Building the barn, part one

The weather at the moment is perfect and after creating the two side beams, today was the day to start "building the barn" which involves erecting the two ends to be (almost) level and then joining the two ends with the 145.75" beams.

The more observant amongst you may have noticed that the original beams were to be approximately 145" long and then later, when we assembled the lower base frame, the number was measured as an average 145.75" showing the amazing precision of our joining process and how tolerances stack when you just don't care!

There are 2" x 4" top plates on walls one and two, the side top plates will sit on top of that, so a composite top plate of 145.75" - 7.00" = 138.75" is needed along with wiggle room of 0.25" per end, so the "hanging top plates" on the side are 138.25" which leaves a 3.75" gap at each end that can be used to attach to both walls.

It matters not, just numbers, too many numbers.

The door wall, wall number one, was raised using those two little pieces of wood as pivot blocks, once in a vertical position we then used our steel right angle for a rough guide and then used a 3' x 4' x 5' tie arrangement (classic right angled triangle) to lock all into place. Then it was a case of screwing down the wall to the base. It was a lot of fun and the pair of us put some work in and had a giggle, for the first time in the construction a ladder was used to correct a joint at the top right end of the wall, this thing has height now!

This wall is now very firm in the XZ direction due to those ties, mostly level and mostly square. The two side top beams can be seen in the photo, fully constructed and ready for the raising of wall number two to an upright position, which should be tomorrow. 

We commented yesterday that the structure coud not be seen from the road, that changed today!
