Re: Source for brass channel
Think about building a cutoff "saw" using 3” x .03” x 3/8” Cut-Off Wheels by Black Hawk Abrasives driven by a 25,000 rpm die grinder instead of low speed metal blades that can't cut hardened steel and can "grab" brass with bad results.
Hack a small power tool like a hobby saw or a disk sander for its slotted table and miter gauge. Add a fence and maybe a "swing arm mount" to raise and lower the cutting wheel. .........Eye protection is a must.
This won't do much for plastic or wood; but if your model making skills are still in that arena you'll be working that issue first.
