Re: AW same as ISO?

AW-32 is ISO 32 with Anti Wear additives. Same thing, just better.

Re: Special Die

1/4"-28 is very popular in automotive parts, over here anyway. The Schrader thread sizes became very important, when buggered up valve core threads became the difference between a million dollar piece of equipment running.....or not. Sometimes, you never know what you might need to know, and have! :)

Re: Special Die

I have a 1/4-32 tap. It's what a lot of oilers are. Why they made grease zerks in 1/4-28, but oilers are 1/4-32....I have no clue. So that nobody would mix them up. Same reason different gasses have different threads, even left hand vs right. Steve Sure.....why not? Good a reason as any! I know peo...

To make me go 'huh?' I suppose.
And have one more tap in the drawer, I've only used a few times.
I still blame opium!

Re: Special Die

The Schrader valve is probably 100+ years old (since 1891 per Wikipedia). There were lots of "different" threads in use then. Once one has become established by common use, it has a life of its own. Consider the light bulb thread. I have an assortment of strange, by current standards, taps and dies...

Re: Eyeglass worn with mask fog getter ridder of-er

In many of the mines I worked, we only allowed disposable masks for a limited number of tasks. Reason being, they sealed quite poorly. We used reuable half masks. After so many lawsuits, at mines around the country, from black lung to mesothelioma, caused by leaky (poor fitting) masks, many mines st...

Re: Special Die

You're welcome Russ!

And, another tidbit of trivia, should you ever run across it; On the large bore valves & stems, used on heavy equipment, the valve core is .305-32, and the OD threads are .485-26.

Schrader.....was on opium....how else could he come up with thread sizes like that??

Re: Eyeglass worn with mask fog getter ridder of-er

NIOSH N95's, like a 3M 8210, which I used to buy cases of, have a little strip of aluminum attached to the top front, so you can shape the mask more tightly against your nose. Not as good of a seal, as a reusable respirator, most of which are made out of soft silicone rubber, but it certainly improv...

Re: Special Die

What you need is a .305-32 die, for a standard Schrader valve OD thread. Last taps & dies I bought, were from fleaBay. Industrial type tire shops usually have them, but they charge an arm & a leg for 'em. Amazon maybe? FYI, the valve core thread, is .206-36. I have bought some taps that were labeled...

Re: Tig welding a tractor part?

Cast steel will break like that too.
I've found front end & suspension parts to me all over the map. Some are cast iron, others are cast steel, as well as forged, most notably Pitman arms.

A quick zap on the grinder will determine if it's cast iron or steel.

Re: Tig welding a tractor part?

You might think about adding a stiffner. Cut it to fit, and lay it inside the ‘U’ and weld it on the sides.

Re: Tig welding a tractor part?

Cast iron, preheat is a must. Cast steel, not so much. I would just warm it up a bit with a torch after I had it all set up to weld. For cast steel, just flip a coin for -2 vs -6. It's not going to make much difference. Personally, I wouldn't TIG it. I'd use a wire feed, or just good old fashioned 7...
