Further post on the bridge

The next step was to airbrush the bridge with aged concrete.

Airbrushed bridge in spray booth

Then test fitting the bridge in place

Bridge in setting

Then working out the river area under the bridge with aluminum angle, foam, plywood, masonite and caulk

Working out the river course

Then fleshed out a little more with rocks, sculptamold, and the start of scenery

River and banks starting to take shape

More scenery and bridge weathering in a future post.

Continuing my Concrete arch bridge

After the second pour was cast and fully cured, I started to detail and assemble the bridge.

Adding stone seam lines stage 1

Then enlarging the grooves with a file, and then a steel rod of the right diameter.

Filing the stone lines

Steel rod in the 3rd stage of scribing the stone lines

I also filed bevels on the vertical edges of the small arches

Filing relief angle on small arches

I then painted the inside walls of the bridge with aged concrete

Testing assembled bridge ( no exterior paint or weathering)

In a future post I’ll talk about painting, weathering and installing the bridge in the layout

Completing my cast hydrocal Cement arch bridge

Back, finally,  to casting the second side of my arch bridge, so to bring things up to date, here are a few shots of the mold and initial pour.

Then back to the present starting the second pour

Both casts with spacer cut from 3/4 inch Sintra (expanded closed cell PVC sheet)

I’ll continue detailing and assembly in the next post

 

Continue working on the Yard & Engine Servicing area

Some Photos showing progress, and also trying arrangements of structures for the engine servicing facility, and how these would photograph in different light (time of day-or weather)

Working with laying track and stone wall at one yard lead

Track down and stone wall further along with concrete cap.

Trying position of servicing structures

Working it out.

Trying angles

Camera and lighting set up after placing structures and ballast, greenery etc.

Pretty interesting article in the New York Times about a new Model railroad Museum to be designed by Architect Frank Gehry
