I’ve been improving my metalworking skills by making a bunch of stuff for the work space. I got a couple more things to build before starting the frame, but it’s slowly getting there.
- I brazed together a frame for my portable bandsaw with 4130 tubing that I got for practice. Now it can be used vertically or pivots down as a cut off saw.
- brazing a bunch of random brackets and hooks. Sometimes with stainless sheets and silver too. Glad I’m building up experience on non-critical stuff
- Got a few more files here and there on ebay and used them a lot. Got a lot more competent at the filing the miters.
- Bought a 3/4" 13 x 31 aluminum tooling plate from the scrap pile at the metal supplier. A little small but it’s cheap. It got some dings but it is smooth otherwise. It’s a lot flatter than the granite counter top I got earlier. Finally I have a decent reference surface!
Next up is doing a full-sized drawing and marking the tubing.
What’s a good way to mark a centerline on both sides of a tubing? Single side is easy but I don’t know a good way to mark the other. I don’t like the results when I divide with a piece of paper.
Also, any downsides to add citric acid in the flux soak? It works great to remove mill scale on hot rolled stuff. Everything comes out of the bath rust free and easy to work with. Unlike HCl, there’s not surface etching that I can see.
