This guy? Even though you don't know me that sounds weird for me to read.
I too am curious however, nobody would answer me over there.

Why is it lame, it is no different than buying threaded inserts, and you cannot drill out and tap tube that is bigger than your thread size, physics does not allow it. If you used smaller ID tube you can drill and thread it, but if you want something larger and dont want to buy like 3/4 wall DOM, then it makes perfect sense to use a tube insert. You could just as easily bore, turn and thread inserts from solid cold rolled, but what difference does it make? Plus, you dont need a large lathe to make inserts or turn down coupling nuts, and you need a pretty big fucker to chuck up and thread a 3-4 foot long piece of DOM.Funkel said:Its pretty lame if you ask me. If you have access to a lathe, do it right and buy the tap and drill you need and make them right.
Lame, huh.........I have the tap and drill and the lathe.......but I am not asking about doing it that way. I'm asking, does it save time and is it acceptable to use the threaded couplers versus using bar stock to make these adapters? If you can get the couplers in the same material as solid it makes sense to me to save time and money on tooling to buy it already threaded. I just want to know if anyone has done it and how has it held up? I know I can go out here and turn em out of 17-7ph stainless heat treated to 220,000 ksi but for you LAME-O guy, this is not what I'm asking........ lets not reinvent the wheel......if you think its a bad idea just say so.......I don't think its right or wrong....:shaking:Funkel said:Its pretty lame if you ask me.

When people say stuff like this, it really makes me wonder if there is any fact behind it, or are they talking out their ass?Funkel said:Among other things, welding in a bung made out of a tube nut that's been plated is going to leave contaminants in the weld. While it may not be an issue, it could compromise the integrity of the weld joint. At a minimum you'll need to knock off all the plating before welding.
Additionally, I'd rather have the added strength of drilling and tapping the core material instead of creating a HAZ. Splitting hairs? Maybe... but if you have a lathe....
i think once you turn the hex off of it to make it round it would no longer be plated in the area being welded. sure the inside of the threads may still be plated (this may actually be a good thing) but i doubt it would effect the weld on the outside.Funkel said:Among other things, welding in a bung made out of a tube nut that's been plated is going to leave contaminants in the weld.

I, like lots of people around here, have spent the better part of my adult life learning how to do things elegantly. You're spending a lot of detail time on your buggy, don't you want it to look top notch when its done? Of course... and you've done a hell of a job thus far making sure that's the case.X-Rated said:When people say stuff like this, it really makes me wonder if there is any fact behind it, or are they talking out their ass?

Is a tube adapter quick and easy? Sure. Does it work? Absolutely. Is there a better, more elegant way? I certainly think so... and guy has a lathe.
Lets assume that a turned down tube nut is NEVER going to fail. You're still gonna have to chase it with a tap after welding (it IS gonna shrink some). So the tap is now out anyway...
So I'd rather have this:

BTW... I still think turning down a tube nut instead of making it by hand is lame.
ON THE RCKS said:x-rated,
i think you missed that he is not talking about normal aftermarket tube adapters like you would buy from PolyPerformance, but the construction style crap from the hardware store. I have used these and i will never do it again. The zinc coating or whatever it is, and the welding screw up the threads and you end up with a less that desirable piece. Granted, my experience is with small, 1/2", adatpters, but it is not as good as either making or buying an adapter out of mild steel or chromo.
