I picked up a couple hundred pounds of scrap iron at a local estate sale the other day.... In addition to hammer heads, chisels, and other things I could use, was this assortment of very lage taps.... They are just stupidly high carbon steel to me, as I pray I never need taps this big, but I figured I would see if anyone on here could use them.
#1 is marked 1-1/16 Vermont
#2 is marked 1-1/8 with a maker's mark that looks like /G\T/B\?
#5 is maked 1-1/2" Wellworth Mfg. Co.
#6 is marked 1-1/4 Wellsbros Little Giant
#11 is 3/4" Wellworth
I don't see anything on any of the rest, but I haven't wire wheeled them. If you want me to I can, but wasn't sure if I should or not... #11 and #4 are missing several teeth, and #3 is missing only one tooth, otherwise they appear to be pretty immaculate aside from rust.
If you're interested in any of them, or would like a better picture of any paticular one, just ask. Make me an offer! I'm thinking $10/tap. $15 for the long ones. I'm also open to trades, particularly looking for handled tools, such as top swages/fullers/etc. Anything stamped Atha will interest me as well. Of course, I also accept paypal :)
Thanks for looking!

? do those large one have NPT on them ??
I don't need any, but they look like they may be pipe taps.
#3 through #7 I think are pipe taps, as they are larger than the diameter they say on them. #11 probably is as well. I have no idea what the long ones are for, but the other short ones I believe are bolt threads, plus #12 is a reamer, and #13 is a giant easy-out...
No need for any of them.
Just wanted to let you know #2 is probably G/T\D Greenfield Tap & Die and #'s 5 & 11 are you sure they don't say Walworth and not Wellworth.

I think you're probably correct on both points! I know when I was writing the post I kept switching back and forth between Wallworth and Wellworth, might be a little dyslexia there :P
perhaps you were trying to say; " It's Wellworth to buy Walworth."
I do not think any of those are pipe taps. I am a bit interested in what value you would place on these individually though.

I agree.
The top two may be for nut tapping but I don't know for sure.

The ones thought to be pipe taps do not have threads on them that look anything like a pipe tap would. The threads are much too fine to be pipe tap threads.

Well, I'm not sure, just a guess.... The ones I mentioned have a larger OD than the a bolt the size of what is stamped in them would have. If they're not NPT, I don't know what they are, unless there's a Metric pipe size?
I honestly don't know... When I first put them up, I thought $20 each would be a reasonable price, because of how stupendously expensive the 5/8" and 3/4" bolt taps I had to buy were... But I see pipe taps are less expensive than I would have expected.... So, like I said, make me an offer if you're interested :) And there are tons of things I'd take in trade!

Can you read any of them?
What exactly is the markings on, say, #5, or any of those first few on the bottom row.
A 3/4 Pipe thread is not 3/4 diameter.

Since pipe is measured by ID and not OD.
rule of thumb; add 1/4" to the size.
3/4" would measure 1" 1/8" would be 3/8" etc.

My initial post says everything I can read on all of them...
I worked in the plumbing field for a couple years, I'm familiar with pipe sizes :P They look the right size for being pipe, I'll have to dig up the few scraps of that diameter iron pipe I might have laying around and see if thry line up...
Twilight Fenrir, try one on an old pipe fitting.
Check the OD and the Threads per inch.
Should be pipe taps.
Yes, confirmed, the ones on the left are all pipe taps. I used a scrap of 1-1/4" black iron pipe I had from a project a little while ago, and it's an exact match. I didn't realize the threads per inch were the same across pipe sizes, I thought they varried like bolts, but I guess. NPT should have given me that clue :P
Anywho, if anyone is interested, I'll do $10/tap +shipping. $15 for the long ones. Though I think I'll keep one of the 1-1/4" taps, as I like using that size pipe for welding projects...

1/2" & 3/4" are 14 TPI
1", 1-1/4", 1-1/2", & 2" are 11-1/2 TPI
2-1/2"-10" are 8 TPI
On a threading machine you only need a couple of die heads - 1"-2" and 1/2 - 3/4"
For fire sprinklers you use 1"-2" 99.5% if the time. Larger pipe is grooved.
