Re: Taps and dies for sale

Might be a good idea to better describe the taps. Are they hand taps, or are they intended to be power driven?

Re: Asian/Chinese made Dividing heads

But I reread and don't see where I referred to an indexer as a dividing head or the reverse. I see your point. I was concentrating on your comment about rapid movements with a dividing head (that is generally not the case, but is true of an indexing head), overlooking the possibility that it may be...

Re: Asian/Chinese made Dividing heads

So I believe I do understand the difference, and I'm still not sure where I trampled on the terminology. I try to be precise, so I genuinely want to know what I said that was wrong. I prefer that it be addressed as confusing, not wrong. In both instances, indexing is precisely what occurs. The diff...

Re: steamin10 (Big Dave)

I received an email from Rose. Dave's heart was irregular, with doctor's prognosis of a chance of survival not favorable. He was removed from life support and passed away around 12:30 today. His candor is going to be missed.
Rest in peace, good friend.

Re: Asian/Chinese made Dividing heads

I thought that was what I was saying. You said: A dividing head as shown in the pictures is really designed for relatively light work which needs reliable quick indexing by division. For instance, 4, 6, or 8 even divisions for fluting a shop made cutter/reamer/etc, or gashing a gear with even divis...

Re: Round Ram Upgrade

I run the mill on a rotary phase converter and only really get 2/3 of the rated HP of the motor in that configuration. Are you positive? Rotary phase converters provide an honest three phase, unlike static converters, which do provide only 2/3 the rated power. In fact, if well balanced, they should...

Re: Show us your milling machine!

I don't use DRO's, but the way I operate milling machines, having one on the quill doesn't make as much sense as one on the knee. I generally lock the quill and use the knee to deepen the cut, as that's how I have the most control. If I'm drilling and need to control depth, I have a quick stop that ...

Re: steamin10 (Big Dave)

I just received an email from Rose, Dave's wife. Here's her comment:
"Harold, dave's heart stopped. After 20 minutes they got a weak pulse and he is now on a ventilator"
Not be best news we could hope for.

Re: Asian/Chinese made Dividing heads

Terminology is being trampled here. A dividing head is not an indexing head, nor is an indexing head a dividing head. Of the two, a dividing head provides unlimited indexing, while an indexing head generally has preselected stops. Both are useful, but not necessarily interchangeable. A rotary table ...

Re: plugging a barrel for bluing ....

I am familiar with the 295° caustic black oxide (I've done it several times), but not at all familiar with what you call rust bluing. However, your response makes it perfectly clear why a barrel would be plugged, and I thank you for that. Sure does make sense.

Re: 12" working railroad

Yeah, it turned to rain, and melted considerably, but as night came, it cooled down and started snowing again, which it is still doing. We now have more than 24" on the ground.
Will it never end?

Re: plugging a barrel for bluing ....

On the subject---plugging the bore of a weapon before bluing. Is that really necessary? It is known that black oxide does not alter the size of an object so treated. Is there any particular reason one would plug the bore? Inquiring minds want to know!
