Cutting square tubing is no harder than cutting molding around a door frame. Use a miter saw. A fine tooth hacksaw blade works well for carbon fiber.
If you don't have a miter saw, print a plastic guide block that holds the tube and has a slot for your hacksaw. Finish with a sanding block to make the edge nice. I've cut a lot of fiber tubes, sharp saws work well. but glass and other fibers dull tools really fast. You can make a really strong part by gluing fiber tube into 3D printed blocks On Wed, Nov 30, 2022 at 8:08 PM gene heskett <ghesk...@shentel.net> wrote: > Greetings all; > > An unusual question.
