Tweco Series 14 tips are threaded in 1/4 28 as stated in their product literature via "Airgas" (Air Liquide). Also Lincoln KP 14-35 are threaded in 1/4 28. (Amazon $7.30 ten pack... no thread info on site) As far as the different size tips go, I've seen the catalog at "Airgas" list .030 .035 and .045 as having these threads. How many sizes beyond that??? Can't say. ALL sizes in the model series as a generality??? Don't know. I have ONLY tested the KP 14-35 as that's what I purchased, however, the literature on these was correct and I would imagine it would be for the other sizes as well. That said, several other sizes in this series had NO THREAD INFO, and as Mikey98114 stated, getting ancillary info from a sales person can be difficult. As far as product details go, "I'm a roast, baste me" (Dennis Miller - "Joe Dirt") however, give me some details!!! Manufacturers produce the tips in a myriad of different configurations with no set standards... REGARDLESS of manufacturer!!! I agree.... know what's what, down to the model number!!!..... and once you do, share... share... share!!! At least until next week when they change the product line again!!!!! I did assume that I'd be able to wing it as I've always done, however, most of the burner designs I've seen utilize parts that have NO SUBSTITUTE without changing the design. And unless the build instructions are followed verbatim "plus", you will eventually have to throw her in reverse at some point!!! The "plus" being applicable skills, knowledge, investigation and common sense. It's just one of those types of projects!!! But enough of all that!!! I'm gonna go play with my buners!!! Thanks again Frosty and Mike!!! Troylet

Okay!!!... apparently Tweco RZ14 carry a 1/4 x 28 thread!!! Now... do they REALLY!!! Off to the welding supply house to test the veracity of the info provided by the guy behind the counter!!! Man, I hope he's right!!!

Thanks Mikey98118!!! I appreciate the info and I don't doubt a word of it.... now... what specific brand and model mig tip TRULY come in that size??? I'm going to the welding store today, and if need be, I am jumping the counter and testing every mig tip in the joint until I find one that fits!!! Assuming I'm successful (correction: make that "on the off chance" I'm successful... 4th largest city in the nation... why would we have a large selection???) I will report back my findings!!! If unsuccessful, I will still report back my findings.... upon my release!!! Seems the one thing that can always be found here are iron bars!!! One way or the other, I'm tipping the maid and checking outta "Frustration Station"... TODAY!!!! In all seriousness, thanks again Mikey98118... I appreciate your time and help!!! Troylet

Thanks Frosty, I appreciate your help!!! The problem I'm having is that while I can tap the the fitting for metric, the inside of that 1/8 fitting is just large enough that there isn't enough "meat" to get good crests on my threads and the tip will just slide in and out. When tapping 6mm, I can literally hold the fitting in my hand.... no vice!!! I tapped some brass caps when I first began this project (before I decided to follow your build) and all turned out well, so I know I'm sized properly for metric tips, provided there's a correct sized hole. Unfortunately, I have to tap for 1/4 to get a good bite with these particular fittings, but it seems that every flippin' mig tip I find, is 6 x 1mm!!! I keep reading that Tweco tips are 1/4 x 28 (or at least some) but there just isn't any info on the thread size for mig tips!!! I'm hoping someone can provide the model number or something of a tip that is definitely the right size as I just can't afford to keep wasting brass trying to figure out a work around!!! Short of that, I'll have to make a welding supply house run and just nose around until I find what I'm looking for!!! They seem to be few and far between in these parts however. You'd be amazed at how much more hardware etc. can be found in a small town vs. the 4th largest city in the country (Houston)!!!! Talk about frustration!!!!... Thanks again Frosty!!! Troylet

Can someone PLEASE tell me EXACTLY what mig tip uses, OR will somehow work with 1/4 x 28 tap??? Lincoln is a no-go... every Tewco I can find are too small as well and I keep reading that Miller's won't work either!!! Building Frosty's T - Burner and 1/4 x 28 is about the only feasible size to tap the 1/8 fitting. Brass is expensive and I'm about outta "live and learn" money!!! I need FACTS!!! Thanks in advance!!!!
