Now here is a question: For a job like that could one get away doing say a
9" plate at 300 rpm if the feed was *really* slow? One of the reason I am
going through this rigmarole is to get the speeds down to 40-80 which the
books tell me would be more appropriate.
Michael Koblic,

That depends on the plate and tool bit materials. The speed limit is
where the tool point heats up enough to soften and you probably won't
see it. For example you can soften and dull the teeth of a cheap
hacksaw blade by sawing tool steel too quickly. 700 FPM at the outer
edge should be OK for aluminum but it's -way- too fast for steel, I
run 80 - 100 FPM, and 50 or less for cheap half-fast-steel Enco end
mills and lathe bits.

***That's what I thought...BTW how does carbide behave in this situation? I
bought a boxful of carbide inserts which were a part of a lot of small
metalworking items in an auction as well as some holders to go with them.

Look at the lathe in Fig 92 of Holtzapffel. The drive engages the
outer rim of the faceplate rather than a pulley on the spindle, so one
part does double duty. A plastic kiddy bicycle wheel might work. The
reversed tapered pulleys, which could be wooden, let you change the
speed through a 7:1 range while the lathe is running so you could run
40 RPM at the edge and 280 in the center. The lever that slides the
cone pulley belt, called a Shipper, could be connected to the slide
rest with a cord to make the speed change automatic

***I did and was suitably impressed. In fact a friction drive of some kind
was something I did consider (and have not totally rejected). At this point
I am mind of aiming for a three-story type of arrangement: Two pillow blocks
with a 9" pully in between, belt through a slot down to the middle level
where additional transmission (yet to be determined) will change the speeds
and a belt from there down to the basement with a motor on a hinge plate
driving it all. But I am not married to it.

I am independently pursuing another arrangement partly based on some of the
ideas you have imparted. But all is on hold as I have been playing withe
mill for the last three days. I have also three dials to finish for the
Christmas shopping rush and a router table (I seem to do more woodwork than
metalwork these days and if I am going to be making wooden pulleys ti will
be even more. BTW, how do you attach the wooden pulleys to the shafts? I was
thinking a split collar with a hose clamp...)

The slide rest is fastened to simple non-precise ways and aligned
parallel or perpendicular to the spindle axis with a test bar or by
measuring the cut. You could try an X-Y table or vise.

***I knew I should have bought that sliding cross vise in the auction the
other day...It has been bugging me ever since.

These are some of the ideas I hoped you would get from the book. The
hard part is hiring enough Egyptians to pile up all those stone blocks
for the base. (It's a 25' x 40' lathe by James Nasmyth)

***The book is a gold mine - thanks for recommending it. Just the
work-holding ideas are worth the price.

You should be -- at least enough to get it under control,
because I was considering replying to your last article and found that I
was sufficiently confused as to who wrote what (everything at the same
indicated level of quoting) that I decided not to bother, because I
would have spent a lot of time re-formatting the article to what I
*thought* represented who wrote what. (The names do not matter, but
being able to tell original text vs replies is rather important.)

If you have too many people reacting as I did, you will lose a
lot of information.

At least one thing which I was going to comment on is that yes,
you can use carbide at higher speeds -- but you still need to look up
what workpiece material for what tool material, and then convert the
indicated SFM (Surface Feet per Minute) speed to RPM at the maximum
diameter at which you will be working.

_Machinery's_Handbook_ is one good source of tables of materials
VS speed, and of formulae for calculating the right RPM. (It also has
tons of other things.) You can probably do with any version from 15th
edition on. I've got 15th, 24th and 25th, and they are now up to the
28th edition.

Enjoy,
DoN.

It sounds like you're talking about the Machinery's Handbook.

I bought a 14th edition for 3 reasons:

1) it was born the same year I was, 1953
2) it contains some of the older, pre-CNC info
3) it cost only $4.25 + $3.00 s/h

Older editions of Marks Mechanical Engineers Handbook are also
interesting and useful for their coverage of older, lower technology
that's simple enough for us to copy. My 1941 edition has sections on
steam engines, windmills, and the muscular energy of men and animals.

His 1922 book on Airplane Engines has detailed cutaway drawings of the
WW1 aero engines and considerable detail on mathematical analysis of
engine performance, presented in a more understandable way than I've
seen in later texts.

The list of copyrights in the 15th edition go back to 1914
(which I presume was the first edition), so I would guess so.

They jump from 1931 to 1934, so I guess that there was not an
edition specific to 1932, but whatever edition was published in 1931
would have been current for your birth year.

And 1941 is listed, so I guess that I could get one for my birth
year -- if I could figure out which edition to look for. :-)

It looks as though there was an edition each year around then,
which would make sense since that was wartime, and there was a lot of
progress made in that field during that period.

There is probably someone here who is collecting all of the
editions, and could answer all of our questions as to which editions we
want.

Enjoy,
DoN.

Not much money back then, although when you consider wages, it was still
expensive. I recall paying $25 for the book, but I may not remember it
correctly.

I do remember paying $75 for my first Gerstner----still in the box from the
supply house. It's one of the larger boxes that will accommodate 24"
scales, and has the drawer in the center for the book. Even my second
one, which I purchased several years later, cost only $125. Haven't priced
one recently, but the last time I did they were over $600.

You ought to figure out what the problem is with your news
program not quoting correctly and fix it, if possible. But
if you can't get your news program to quote things correctly,
manually add a greater-than or quote marks at the beginning of
each quoted paragraph. The few seconds to do that will be
repaid by not wasting the time of hundreds newsgroup readers.

Certainly. It helped greatly that the sand was very dry there,
considering that I typically wore no shoes outside -- unless going to
town or school. :-)

IIRC -- I had a choice of a tingle when the drill was off with
one power cord orientation, or one when the drill was on with the other
orientation. And of course, there was no ground lead in the power cord
in those days.

The switch was a slide switch on the top of the D-shaped handle,
not the later trigger switch.

I have no idea who made it. Back then, it was just "my electric
drill". :-)

Three comments:
1) The new software (OE-quote fix) makes this manoeuvre unnecessary from my
point of view (I do not know, however, how many others there are with the
same problem though) - provided I remember to turn it on! It did not come on
with the OE but then I was fiddling with it quite a bit yesterday.

2) The manoeuvre as performed does not cure the problem - bare OE still did
not pick up the quotes correctly (which is how I knew the Quote fix was not
on).

3) If you think people were confused before, wait till you start omitting
quotes :-) I thought at first that the first line was quoting me ("I never
said that, did I?").

Actually -- the quoting above is as it should be. Each
attribution line is shown at one level lower than the text to which the
attribution applies -- because the attribution line is generated by the
system quoting the text. So -- since none of *your* text was actually
being quoted there, the attribution line starting with "" (above)
should have been deleted. You would have kept it only if there was text
with "" in front if to (one more than the level of the attribution).
I left it there because we were discussing it. :-)

But what you are producing is now *much* more readable.
