Again, I am new to all this so forgive my ignorance but the lugged frame set up looks like you would just stick the tubes into the lugs, that the tubes would not have to be mitered. Is this true? (Kind of like thise strong tier kits you can buy to build a table ot whatever without having to cut miters).


Good lugged joints are mitered for maximum strength so plan on mitering
the tubes.
I have no jig and would have to rely on a table or system of 2x4's. Some kind person on here mentioned somethign that I had read but forgot about, pinning. Seems the old timers if I understand it correctly would drill the lugs and tube and insert "nails" to hold the assemply togther before brazing. WOuld this negate the need for a jig?

I expect you can do without a proper jig if you have some sort of flat
surface as a reference and can set-up the frame and pin it before final
brazing. A decent spirit level, angle gauge and packers should get a
level frame set-up whic can be pinned and brazed.

She covers everything from design to brazing to building without a
jig, bidon mounts, the lot.
