Good. Then my mill's max of 2950 rpm shouldn't put too much strain on them. :)

It's actually quite a detriment. The tiny tip is very easily broken by overfeeding. When you go this route, make all your movements very slowly. You'll have much better luck with aluminum than with steel.

If line width isn't critical, you may wish to investigate the use of a small ball end mill. It will be somewhat more robust and not as easily broken, although at the expense of a heavier and shallower line. Same scenario----you can throw a huge amount of speed at the cutter because of its small diameter.

Hi,

These were simply scratched in .015" deep with a 60 degree threading tool held sideways in the tool post. A similar tool could could be held in a mill collet and then dragged across the face. No power needed.

dalee and All--

The "dragging" option is what I am going to try. Thanks!

It sounds so easy that even a seal killer could do it.

Bill, was there at one time an overpopulation of seals in the Land of Oz or are you just hard on devices that impede leakage?
Sorry, I guess it's my day for being ornery, LOL

Long ago, Kansas was stricken with a mutant bread of seals, killer seals. The pseudonym just stuck with me after I eradicated every one from our state. Eventually, I traveled the world doing this work. Today, although I am old and weary, my efforts were fruitful; my work is done.

Your friend, seal killer

That is a sound concept. In my youth, I had P.O. Ackley build me a 458 Winchester magnum rifle. It is one of the successful cartridges used in hunting elephants.

I am proud to say, Utah, where I lived at the time, is free of rogue elephants, a fact I attribute to my ownership of the rifle in question.

Thank you. But for you, they may have bred and come to Kansas.

I always knew we were brothers in spirit.

Are you certain of that? They can be clever little devils. I have it on good authority that they have been known to paint their toenails red and hide in cherry trees. They could be preparing to storm the Capitol building in Salt Lake City as we speak...

Thanks for the timely tip. I have a nephew in the Salt Lake Valley, who I will notify immediately. Sadly, he has no 458, so he may be unable to resolve any issues that arise.

I've been gone long enough that they may have returned, secure in the knowledge that the gun is no longer there, and P.O. Ackley is now deceased. Hiding in the cherry trees is a great way to avoid detection, and, assuming they have returned, I assume there's no shortage of trees. The south east portion of the Salt Lake Valley was, at one time, well known for it's cherry production. They were of the finest quality, with robust flavor. That may well be the only thing I miss about Utah.

Sadly, the Utah situation has indeed deteriorated since your departure. Rogue elephants are now so common the state was forced to declare the cherry to be official state fruit.
