Metal trusses from scratch
Posted by OldSchoolScratchbuilder on Tuesday, April 16, 2019 6:59 PM

Used HO brass rail to construct metal trusses. I’ll use these pieces to scratch-build a trestle leading to a miniature mineshaft turntable. A Spectrum MOW vehicle will pull carts out of the mine shaft, then back them into the hillside loader building. It will all be run from a dedicated DC supply.

Good use for brass rail! Most people won't notice the difference in profile from an actual 'I' beam once the whole bridge is built.

Maybe I'll buy a bunch of brass track at the next show if the price is right.

I would agree the trusses look pretty decent.
If Old School returns to this thread, perhaps he could say if he soldered the rail together (or cemented/CA'd or something else), how did he cut the rail to the right angles and size, what kind of jig (if any) did he use, what are the gussets made from, and so on.

Four materials: HO brass rail, coffee stir sticks, E6000 and black paint.
