April is here! The concept for my SP Jawbone Branch layout is now five months old. The first two or so months were spent developing and refining the concept and track plan. January saw the materials purchased and the cutting start. The construction began in earnest in Feburary. March saw more construction and the structure of the first four panels nearly complete, plus the wall mounting brackets fabricated. To see the complete list of this blog topic, see my SP "Jawbone" Branch Index Page, which has links to each part.
|Overview of the four main modules assembled and resting in place.|
|1/4-20 bolts with and without nut and washers|
First a Jig
|My new Drilling Jig.|
|The Jig is clamped in place on the module end.|
|The west end of Owenyo #2 module|
|End plate for future Owenyo #3 module|
At this point, I might as well drill the Owenyo #3 end plate, which I have already made several months ago during the early construction phases.
|Owenyo modules jointed and bolted in place.|
The 1/4" bolts are fitted and in place. The modules are held with the friction, I may increase the size of the washers, but at this point the bolts are not under much force to clamp and distort the frames of the modules.
A Word of Warning
|Ah... oh well, I did put the Jig on backwards once! - Oops|
Do I Need Alignment Pins?
|Pretty good vertical alignment at Owenyo #1-2 Joint|
|Mojave Staging joint. The edges are slightly rough.|
|A higher angle view of the Owenyo #1-2 joint.|
|1/4" MDF shims installed along wall to straighten modules.|
Thankfully, the 1/4" shimming was enough to allow the modules and the surveyed center lines to come parallel again. Now I only need to adjust the track centers 15 scale inches.
With the main construction of the Owenyo modules reaching a stopping point, it is now time to dismantle the upper deck of the stacked layout.
|Mojave Staging Yard track laying starts next!|
