Cleaning tools thread pitch & diameter/size?

[THEMULE]

Not sure where this question belongs. So I put it here, my favorite era.
I think the thread pitch is 32. Not sure of the diameter. 8 or 10?
8-32? 10-32? Neither one seems to match up exactly right. The # 10 seems close.
Thanks for your help!

What era of S&W production are you concerned about ? Many S&W cleaning tools were vendor supplied, so consistency of thread & pitch dimensions is not standard. In the days when S&W made their own tools they sometimes used a proprietary thread & pitch. Ed.

Are you talking about the thread used for cleaning rods, wire brushes, etc?

...and find a chart of bolt dimensions will give you the fractional size or number. That's half of it. If it's not a proprietary the differences in pitch are far enough apart incrementally to be able to tell, but if you only have a short section it's tougher and easy to be fooled. It's most likely that they are finer than standard threads. I looked up Dewey rods and could find the info.
Maybe buy some nuts to try on them.

Dear Ed (Dad), being a Master mechanic for the major part of my life I immediately realized the older S&Ws (and other guns) did not have a Standard Thread as none of the thread pitch gauges matched perfectly. I once almost ruined the threads on a US American shoulder stock to clean up the the first few threads that were partially flattened. That's when I became extremely cautious of thread size & pitch on the older guns.

When cleaning up threads and nuts for the Model 3's I had a few custom taps and dies made. They weren't cheap but well worth the price. It was hard enough to find the screw blanks (most of which I had made), but then tapping them is a very tedious job. It made me admire the gunsmiths and firearms mechanics, machinists and fitters of olden days, even more so, who had to make the screws, too.

Col Charlie Pate helped me out with the Upper latch screws on a Schofield replacement screws many years ago. The screw heads on mine (that I had recently acquired ... recent being 30 years ago) were so boogered that I had rig a narrowed welding rod to weld a nut onto the stub that remained to then be able to turn the screw shafts out without damaging the catch or the barrel.

Charlie is such a gent that he just sent the replacement screws to me refusing to charge me for them. Likely because over the years I had faithfully supplied Charlie with about a 5 serial numbers from US Calvary model 3 American numbers. I once had one in awful shape that was a mix and match from 3 different Cavalry serial numbers. Then (I didn't know) he also kept track of US Colt's, too. Thus I've faithfully been sending US Serial Numbers to Col Pate for about 3 decades now.

Per Colt, Shipped to Governor's Island, NY in 1861 in a box of 100 revolvers as part of a 1000 revolver order of blue revolvers (Colt could not do nickel or tin after the factory burned down near that time). This revolver had previously been blessed by Ron Ogan, Herb Glass, Sr. and Tom Haas as original and genuine, however it had NO US markings anywhere on the gun nor was there any evidence of the US Markings being removed. It just did NOT have the US Markings. It was suggested that likely the revolver was removed from the crate by an Officer and sent to one of many hundreds of master gunsmiths in NYC for the nickel or tin ( I still don't know which it really is)

Col Pate advised me only about 2 years ago, that the first 2 US Government Orders of the 1860 Colt were NOT U.S. Marked. The subsequent orders were U.S. Marked but the first 2 orders were NOT. Mine being SN 51xx Col Pate advised was part of the first U.S. Order of the Model 1860. Col. Pate is a walking encyclopedia on US gun subjects, orders quantiies and serial numbers !

I got a little off subject track here, Ed but hope you didn't mind.

Huh oh..... Didn't realize "era" would affect this...... 1940's mostly. Late pre-war & early post-war.

Dwalt, yes Sir. Cleaning rods, brushes and mops.

Thanks,
Bob

Common sizes in general are 8-32 for Hoppes, Kleenbore and most modern

8-36 is Outer's and US Military

[gmborkovic]

I thought we were discussing wire size and thread pitch on cleaning rods and mops/brushes?

[Big Cholla]

Why don't you just run a 8x32 taper tap in followed by an 8x32 plug tap? That way you will 'know' it is an 8x32 thread and the vast majority of bore mops, jags and bronze brushes are threaded 8x32. It is not like the cleaning rod is an integral part of the handgun. ........

And, I just went out to my shop and checked every S&W cleaning rod that was handy and I confirmed that they were all 8x32 threads from S&W. ...........

Mike, as always ... the intent and information flew right over. The reference being pre-standardized thread (TPI) and thread pitch on just about ANYTHING manufactured, e.g. SAE, etc. which could have been used on almost anything prior to about 1930s. Same as standardized electric plugs, voltages and amperage and so much more.

A quick read here might slow down you persistent slamming of my posts. I have tried everything to treat you as a friend when we first met at Palm Beach Collectors Club a few years back and without fail, you persist in just being a PITA, verbally abusive and a nasty old ***. I took the first step, in good faith, by calling you in December to offer to put our differences to an end and peacefully co-exist. I spend 3 months in the hospital from 1/18/16 to 4/8/16, of which you had NO knowledge, of facts about, and no first hand information ... yet you opened a thread to post that I am texting from the hospital while I was still in a coma. *** ? I surely don't know everything and I'll be the first to admit it, yet, you just keep on going like you are the Master Know it All of all subjects. No matter who slams you down or how many times you've been penalized by being reprimanded and restricted from posting in the forum ... you just keep right on going. I surely do not understand.

Years back, approximately prior to 1930 ( and surely all ages earlier than that ) there were no standardized tables for threads per inch and thread pitch. This applies to any and all items manufactured with threaded components.

Easy boys.... Don't tick off the big Monkey

Big Cholla,it was 8x32. Thank you. Not sure why I said 10x32..... Brain fart I suppose.
I tried to thread a 8x32 tapered tap into a couple cleaning rods late last night and it got hung up immediately. Must've had a bad spot towards the "beginning of the end" so to speak.
Thanks folks.
