Pin Connected Bridge

Post by Ross A » Sat Apr 21, 2012 5:19 pm

All,

I am finishing up a Phoenix Column Pin Connected Bridge based on an old Gazette article by Jim Vail. Similar bridges were used on both the NPC and SPC. It will soon be used at Deception Cove on my freelanced PC&N Ry.

It has been a fun scratch building project and researching these old bridges was also quite enjoyable.

Nice looking!

Based on your other post, I take this to be HO scale for your HOn3 layout.

Brian,

Thanks! Yes it's for my HOn3 PC&N Ry.

I managed to get the bridge abutments cast this weekend and the stones roughed in on them. I am trying something new on these, I should know in a couple days if this new technique is a winner or a disaster!

John,

May/June 2001 is the construction article, I believe the July/August issue covered installing it on Jim's layout.

Ross, Just an old memory of working on the C&TS... We would thunder out of Chama with a double header, thumping across the Pratt truss at Chama River...The loose diagonal rods would flap loudly, clinking together! Same as we rolled home, it was a welcome sound that the day was almost over. Then an engineering firm tightened the rods up. Man, did i miss that sound!

Well my bridge abutments came out closer to the disaster side,rather than what I was after. I experimented using Durham's water putty instead of plaster. It appears that you have to get the timing just right with the correct amount of drying time before carving the individual stones, to achieve the affect I was originaly after.

Once they are installed and the scenery worked up to them I think the will be acceptable.

Abutments are installed and painted, not quite what I was after but I am liking how they turned out.
