Wish I had ordered a long regular or plug tap now-
here is what I did- I had a regular one from hardware store (6$)
I bought a 6 inch 1/8 stainless pipe nipple. Put the tap in the lathe with the cutting part inside the chuck- but inboard the jaws. Turned on lathe. Used abrasive cut off blade to rough down the square portion remaining- until I got it down to flats.
Then I ran a carbide bit down it to true it up. Sized it to just drive inside the pipe nipple. Put silver solder flux on joint and
pressed them together. Dropped some flux into pipe nipple from other end so it ran down to interface. Dropped in about 1 inch of silver solder (high temp)
put tap and extension in stainless coffee cup full of water so all the tap threads were below surface.
Heated joint gradually with oxy till dull red. Tried to come off heat on tap shank very slowly. let cool in still air.
I expected to see the solder run out to outside of joint- but did not. I think I remember though- when I bought that solder I got the higher viscosity type which doesn't run away so easy. I think I will gently tap on the joint tomorrow on anvil with my 2 oz ball peen- the try tapping at test hole with it to try to verify the joing wetted. If I am still in doubt I can do another heat with some solder wire wrapped around the outside of the joint.(so I can see it get hot enough to wet.....)
Not sure how much I insulted the heat treatment of the tap shank- I think the get less hard as you move away from the cutting section. (if that helps...)
That should work IF the SS joint is good AN IF the shank hasn't gotten screwed up from heat.
If it doesn't- I blew 6 $ I guess-
and Kodiak will get another order from me.....

PS 1/2 inch seems like a good little bit but that may be the just about the taper on the tap they used ?
Looking at the studs - looks like they want the little nub to touch before the treads tighten up. Should be able to feel that
fairly distinctly when I get there....
Started installing the 60 over valve springs tonight using the leslie thing with the wheel. All most not enough travel- have to screw the new spring into it before I start compressing. It worked ok on the first one though...
