|The revised cut file - additional trusses and cross bracing|
I put a sheet of .015 in the Cameo and let it do it's thing. I wasn't looking at the time exactly but I'm guessing the cut took about 20 minutes. I set the blade all the way down and set the machine to double cut. Even with this, the pieces still had to be bent and broken out a little.
|Cut sheet of .015 styrene|
Once the parts were separated, I used .030x.060 strip styrene to laminate to the truss frames to create an angle steel look. It is still tedious - I cut and fit each piece and it took about 20-25 minutes to make up one truss. If I set up for mass production and pre cut all the members it would go much faster. One side received the strip on all members. The piece still felt a little flimsy so I added additional strip on the opposite side, but only on the primary structural pieces. It's still work, but I'm happy with the results and more importantly, the trusses will maintain a consistency that will help keep the entire structure neat and proportioned. They look a little finer and much better than what I've done in the past with jigs. I still have many buildings to construct so I'm sure I will be building lots of these. I will probably go back and do the trusses of the stalled soaking pit building using this method.
|Cut out, ready for assembly|
For the cross bracing, I used .030x.125 strip between the pieces. This packs the bracing out to fit nicely between the web of 1/4" H columns .
My next experiment is using the machine to score thicker, .030 plastic for the gas washer plant for B-Furnace. I'm basing the structure on photos and some HAER drawings but it's free lanced. The dimensions are fairly accurate I believe.
