New Project - 140' Thru Plate Girder Bridge - Part 3

Today , I got back to working on this project. I make the needed adjustments in the parts and laser cut out the new parts.

Above are the new parts. below I will start with gluing the lower flange onto the web piece.

Next the top flange

Once the top flange is in place and glued. Then I work the each end. I like to bend the piece around the corner a couple times so it starts assuming the round corner shape before trying to glue it.

Two girder are completed to this stage with their flanges in place

Next is to insert the overlays that provide the angle detail

Completed the overlay stage

The over lay stage is where I had issue last time, initially my thought was a dimensional error or humidity, but today I tried a different approach to each girder and discovered it was the glue decreasing clearances. The one glued with ACC when together the best. I am going to adjust the dimension a little more to account for this.

Next up is the final pieces and the most tedious part, adding the vertical leg to each angle position.

The vertical pieces

First five installed

So that it for today, going to finish the remaining pieces tomorrow.
