Probably a dumb question. But if I had stainless blade could I weld it to a regular steel bolt to use for a tang? 

Just make something!

300 series stainless can be welded to mild steel using 309 rods.  But, you are dealing with a martinistic stainless so in theory you could but I wouldn't recomend it.  Get some silver to braze it or I use an Allstate nickel copper brazing rod.  I use these (mostly the latter) to braze bolts onto the tangs of my knives.  It's really stronger than if you welded (and I'm using simple carbon steel).  Since brazing takes place below the hardening temp of the stainless you are in no danger or forming a hard spot that will break.  I believe there's a post on doing a narrow tang knife where I show the simple jig for doing this.

If it were simple carbon steels one can mig weld the bolt on then with a small hammer forge the weld at red heat just to refine the grain.  If you didn't do this the weld would break.  I don't think it would work on stainless.  Brazing would be stronger anyway.

Rule #10;  "I can make that" translates to; "I'm to cheap to buy it new."

Recently a young man brought me a stainless throwing knife that had broken at the handle.  He understood that it couldn't be fixed in as much as making it usable again, but having sentimental value he wanted it put back together.  I tried the Nickle rod 3 times and it never would do right.  The forth attempt I used the 45% silver, that did it.  I'll have to talk to the Esab techs about why the braze wouldn't take.  That stuff may not be compatible with stainless as I had thought.
