They are pretty when they are finished.



But who knows what this is? Boy, I am sooooo glad to be able to photograph it. Who knows why?

Gary,

Nicely coming along! A pain to machine but wait till that will be finished, polished?

Pedro

I know what that is. How the heck did you get it out so intact? I have lost entire afternoons over them.

I always get mad at myself and figure I must have been in too much a hurry. Even the "Master" has those days.

I suspect that is a broken tap?

My guess too, broken tap.

The “snap” noise when one breaks off is one of the worst sounds in the working world, sounds JUST like hours of extra work, if not days.

That stuff is looking nice . Well except for the broken part . I’m not sure what that is . It doesn’t look like a tap with the pointy tip . Kinda looks like a cement drill head . Probably something custom you made .

I can’t believe Rotor isn’t jumping on that SS . It would be a nice match to his Barnes Alaskan long airgun !

Thanks
Kurt

Sorry Guys, I didn’t follow up.

Yes ... if you said “Broken Tap”, you win a trip to ... “your fridge”. Make yourself a Sammich!

I was done the hideous job or “tapping” a blind hole in Stainless Steel. I was winding the tap back out, feeling for resistance. Being done with the job, I must have allowed myself a nanosecond of stress relief, when the tap stuck and “CLICK”. And thus began a review of my life. Getting a broken tap out, is akin to (pick your example of ...) superhuman skill and dumb luck.

The hideous part is that Stainless wants to grab and fuse with Tool bits of any kind. The smallest bit of friction produces an excuse for the metal to grab and bond to the Tool bit, with a death grip. Thus; with taps (which are inherently brittle), it’s a highly stressful situation. Drill/Tap charts (made by tap manufacturers ... hummmm), are designed to assure tap breakage in anything but mild American Cheese. In Stainless, the tap swages and “displaces” metal, as much as it cuts and removes chips. So you must know your material (mild stainless, harder mild stainless, stainless annealed Tool Steel), and adjust accordingly.

I’ll be back to finish ...
