80 series rod end tap?

[Kavik]

Anybody got a RH thread tap for 80 rod ends? I believe it is 23mm x 1.75? The drag and tie rods I got from Marlin need a little thread chase on the RH threaded side...

Buy you a beer?

Are you sure on the size, none of my catalogs show that size. Maybe grind a notch in one of the tie rod ends and use it as a chaser?

 

[Kavik]

I'm not sure of the size, that's the problem. I know the "flute" trick, but I'd rather not grind on my brand new rod ends. Anybody have an scrap old one(RH thread 80 rod end)?

Mine are a 1.50 pitch. The major dia is ~20.7, a 20mm thread is ~19.8, 22mm is ~21.8, so 21mm maybe? 21mm isn't even listed in the machinist's handbook!

I've got an email in to the Marlin camp. The tubes might have been point cut on a lathe, rather than a hard tap. I'm fairly sure the tap exists, but I doubt it available in catalogs.

Back in the day, I used to build bicycle frames. The bottom bracket (the spindle that the cranks spin on) threads had a metric diameter with a thread per inch spec. Weird.

I believe the 80 ends were available in 21mm and 23mm diameters. I'll double check the actual ends/rods...to see what I've got.

Marlin tells me it is 23mm x 1.5. If I can't find a tap local, they would take care of me.

Kevin, is this one in the book? Anybody else have/seen this tap?

Thanks!

The catalogs that I have and the machinist's handbook only list even sizes in large metric, 20, 22, 24, up to 48mm. Most of the time that means custom, not a problem, just lots of time and $$$$$! What is the major diameter of your ends?

What is wrong with it, I have a metal lathe?

I'm picking them tomorrow to take a closer/second look.

Kevin,
Thanks for the offer, pm me what part of town you are in. I haven't had access to a lathe in a while

If he mentioned that he had 3 that would be bragging

Threads are simply under cut. Meaning the major and minor diameters of the thread pitch are too small. Not sure what to do other than send them back to Marlin...

I would send them back, picking up and recutting an existing inside thread cut on a different machine would be difficult and he should make it right.
