Guest imported_Roland Posted March 8, 2008 Share Posted March 8, 2008 Hi Guys, I am rebuilding a mechanical oiler and discovered that it has obsolete 1/2" x 22 threads (not 1/2" x 20 or 24). Is there anyone who will let me borrow a tap or die of this size for a week? If I borrow a die (preferred), it will be to make a steel threaded rod that I can use to reform brass threads in a 1/2" x 20 flare nut. If it is a tap, I'll re-cut the brass threads. Of course, I'll pay shipping.I have been looking in all of the usual places and have quotes of $100 to $150 to custom re-make this definitely a non-current size old size !! A thread file will not work since I need to modify a 1/2" x 20 flare-nut. The "Precision Automatic Co." mechanical oiler goes to my non-running 1910 Rambler which has had pieces lost over the years.

nearchoclatetown Posted March 8, 2008 Share Posted March 8, 2008 I'm sure you know, but just about any thread can be cut on a lathe. Are you positive of the size? It does not show in the Machinist's handbook. Link to comment Share on other sites More sharing options...
1937hd45 Posted March 8, 2008 Share Posted March 8, 2008 What is close in Metric? Link to comment Share on other sites More sharing options...
nearchoclatetown Posted March 9, 2008 Share Posted March 9, 2008 12mm would be .472, don't have the pitch chart in front of me. I'm thinking it would have to be 1.25 to work out close to 20 or 22. If 1/2 X 22 is really needed finding a 'chinist with a lathe is the quick way, but they are expensive!! Link to comment Share on other sites More sharing options...
rmartens Posted March 9, 2008 Share Posted March 9, 2008 About 15 years ago I needed some stepped studs in order to use some generic American Racing wheels and lug nuts on my '56 Buick Century. I asked the head machine shop instructor at the local vocational college if his students would be willing to tackle the project.All I needed to provide was the Grade 8 bolts with the larger diameter. They cut off the heads and cut threads of the smaller diameter on that end. As I understand it, it took them three passes each on the lathe--and I needed 20 studs. They did a great job!

nickelroadster Posted March 9, 2008 Share Posted March 9, 2008 A quote of $100 to $150 seems rather steep. Within the last year I had a 7/16" by 32 tap made for $39.95. It took a couple of weeks and I think they ordered it from somewhere. I am in the Atlanta metro area and would be happy to give you the name of the outfit if you want.

nearchoclatetown Posted March 9, 2008 Share Posted March 9, 2008 It may have come from Weddel sp? in Florida. They make just about any size tap you could possibly need. Link to comment Share on other sites More sharing options...
nickelroadster Posted March 9, 2008 Share Posted March 9, 2008 Just thought I would go ahead and put this up. The place I got a custom size tap is "Threads for the South" at 770-425-3787. Link to comment Share on other sites More sharing options...
Guest imported_Roland Posted March 10, 2008 Share Posted March 10, 2008 Hi nearchoclatetown,I looked all over for Weddel and could not find the place. Any chance you could check on the name for me, please? Thanks, Roland Link to comment Share on other sites More sharing options...

Guest imported_Roland Posted March 16, 2008 Share Posted March 16, 2008 Thanks to all!Maybe someone has a flare nut sitting around in a coffee can that is 1/2" x 22? I heard from one guy who thought he did: not.Regards, Roalnd Link to comment Share on other sites More sharing options...
