I've made a few frames now with a TIG, a drill (for bottle cage and vent holes), an angle grinder and a digital angle box. From frame #00003 onwards I also had a laser level box which I highly recommend.

You will need some kind of basic fixturing but this can be homemade and does not have to be high precision if it's adjustable.

I do own a cheap tubing notcher but I actually prefer hand-mitring using templates. I just use a worn-out flap disk on the grinder.

​​​​You can use hand files (and saws) of course too. What I like about the grinder is you don't need to clamp the tube hardly at all. I ended up prepping so many practice joints with the grinder to save time that I got better at it so just use it for everything. I don't get absolutely perfect fit up and this is something I'm always trying to improve, but it's good enough.
