…..............................................................--- Mesa Part 1 ---

=========================================

Construction of the mesa that hides the hidden track from the mine's maintenance building to the hidden staging for the 'empty' coal train but first.....

I was going to move the tunnel portal that is on the side of the mesa facing the center of the layout a little ways down the two tracks to the mine. At that point the tracks are no longer on a 1 1/4” centerline so none of the double track portals I had designed and printed were wide enough for proper track clearance. I used Fusion 360 to widen one a little over .25 inches and decided to print it with the resin printer which is faster than the filament printer if I print it flat (still used supports but should of tried without). The print was less than an hour but forgot to actually time it.

As you can see the mortar joints are sharper and I could of narrowed them up (would of taken a lot of time). The joints are oversize but about as narrow as I could print them with the filament printer. Withe the resin I could narrow them up to about half of what they are but in reality that might of actually looked worse viewing the print once mortar was placed in the joints ( I normally use Tamiya Putty) and personally I like the rougher edges on the filament print as they seem more natural but all of that is a subjective call.

Then decided to move the portal back closer to the crossing in the tunnel so didn't need the wider print. Will save it in case I do someplace else.

The areas where the retaining walls are needed will be measured then the walls will be designed and printed.

Above you can see where there is a crossing in/under the mine buildings where the 'empty' coal train can cross the adjoining track and disappear into the maintenance build and then into the mesa that is being built. The hidden track for the 'loaded' coal train enters under the mine buildings and will exit next to the thru track.

Loading chute building wings will be added to the building above and will go over and hide the handlaid crossing .

I had the spackling out filling some holes at another location but took a few minutes and filled some of the seams and holes in the rock face above. So far I haven't found a negative to using spackling compound. I'll thin it a little with water at times if needed otherwise use it right out of the container. I do have a large box of Sculptamold that I need to try since I bought it for this also.

At this point my tools I've been using are the hot wire foam cutters, mentioned ( HERE ) and the two wire brushes and the heat gun shown above. They seem to be about all I need to this point.
