I've got a small Tig welder and it's great on mild steel and stainless steel tube work.
I use a metal cutting band saw drop saw to cut up my tubing as it makes nice square cuts. You can just as easily do it by hand with a hacksaw though.
If you make the joints with nice tight clearances you can fusion weld the tubes together with no filler rod. This will polish up beautifully but you will still see the weld. I fusion welded mine but used a bit of filler rod as the fusion weld undercuts the join a little. I wanted to linish back the welds so it looks like the whole thing was made from one piece.
To finish off the welds and polish the pipes I've got a belt linisher attachemnt on my bench grinder. I use a coarse emery belt to take down the weld and then a finer belt to blend out the weld. I finish off the linishing with a scothbrite belt for a fine brushed finish which looks pretty good too.
Next I buff the pipe using a stiched sisal mop on a spindle on bench grinder and use the black polishing compound. Then I go to a stiched callico mop with brown compound and finally a loose leaf callico mop with white compound. It takes a bit of practice and patience but the results come up like chrome.

Nice work Mikie,
but I'd do it a little different.....
Jump in the Magna...head to Repco.
Not only is it quicker, but you don't get RSI explaining your technique in a 'how to' thread.
