<p>Well, I had to set it outside, I know that sounds bad, but the
old stuff can set outside if coated with used oil and then power
wash it a little steel wool and it is in good condition. Old
machine tool stuff does not pit if ti is by itself. I save used
oil from the tractors & trucks and use it to oil machinery
that has to sit out. These old pieces are flat belt driven
machines converted to individual electric drives. I have
converted some to VFD and made some really nice machines. I need
to get a 28 Plymouth sedan project in a container so I can move
some machinery inside.. My 12 ton forklift needed an engine
transplant and the help I had to do it went to the offshore oil
patch and I ended up doing everything by myself.. My old forklift
is a tricycle type Gerlinger that was used on an aircraft
carrier. It had a V-8 Mercury Industrial with a 4 spd trans and
reverser. It drove a truck axle that had a giant roller chain
sprocket that drove a 30 in sprocket that was connected to the
rear 20in truck duals. the old Mercury was so low on compression
it would not fire on ether, so I found a 6cyl ford and 2spd fwd
& rev trans out of a pneumatic roller. Removal of the Mercury
involved 3 hours with a cutting torch. Going back needs a crank
pulley machined to attach a 4 groove A section belt pulley to
drive the main hydraulic pump. The cylinder is a 14in x 12ft long
ram. It takes a lot of oil to move it. One of these days I will
get it running. If the rainy season quits here I may get some
things done.. This morning it was 30mph gusting to 40 with
freezing drizzle.. Yesterday was shirtsleeve weather....<br>

<div dir="ltr">You "forgot" a 48 x 120? ;-) I guess you must
not be walking past it very often. That's quite an amazing
assortment you've got there Cecil and you're right that not many
younger folks have any clue about the big, old, manual stuff.
Still has a place in this world however. CNC is great when you
need a lot of parts, but, parts you'd make on machinery that
large will not be in high-volume demand! Used machinery dealers
would probably enjoy taking a tour of your place and cutting you
a check for the whole lot.

<p>After Ithought a little, I forgot about the 48x120 gap
bed lathe, the 24in shaper, the 12x36 surface grinder and
the other one sitting outside that was dropped off a
forklift at the shippers. I have a 36in Yates American
Bandsaw that a forklift operator dropped while loading.
It was one the Navy owned during WWII that sawed the
decking for ships. I have another 36in that I need to try
to get working. I also have a 40 ton horn press. in
addition to the 40 ton ironworker. and a Warner swasey #2
turret lathe, and somewhere around here is an old screw
machine. There is a couple of multiple spindle drills and
all manner of old machines.... There are not very many
young folks that know how to operate these old machines.
Just not a lot of demand for one-off repair work either..
Both old guys that were my teachers in my machine work are
now gone.. <br>

<div dir="ltr">I was just out on the factory floor and
noticed one of the CNC's was about to hit a bar change,
and figured I'd try to capture a video of the whole
thing. It starts with a quick overview of the CNC and
the bar feeder sitting at idle. Then it shows the part
being made, which is the handle of our double-ended
machinist scribe. Then I fire it up to make the last
possible part before the bar is effectively consumed,
then we see a part being made, although it is kind of
hard to see due to the coolant splash. Then it does the
bar change, consisting of pulling back the "remnant"
(the end of the bar that's now too short to make another
part) while dropping a new 12' bar, engaging it, and
feeding it into the machine to continue automatic
operation.

<div dir="ltr">Wow, Cecil, that's quite an equipment
list! Some big heavy stuff on that list! The only
manual machining I do is making little tools, jigs
& fixtures, and "my" shop here at work has just
one (very nice) Hardinge HLV-H "Super Precision"
lathe, a 2J-head Bridgeport, a Kent 6x18 grinder,
and a DoAll bandsaw. The magic is always in the
accessories; the 5C collets and the 4-jaw chuck for
the Hardinge, the R8 collets for the mill, the
various precision vises and other workholding for
mill & grinder, indexing heads, and a whole
compliment of cutters, drills, taps, wheels, etc
etc.

<div>Oh and I do owe you a response on the ESAB
plasma cutter. Unfortunately, it's a pass.
Sorry. We have this one job we're developing now
that involves making rather precise cuts, but
we're already down that road with a chop-saw
that's working quite well. We just do basically
zero with sheet material most suited for plasma.</div>

open a machine shop when I retired.. However,
here in OK <br>
there is not much demand and the only jobs I had
were making some <br>
decorating crap for some traveling vendors. The
biggest job was wire <br>
forming for some Potpourri Pie holders. I had to
build a jig to bend <br>
the handles with an air cylinder and rack and
pinion. Then I had to roll <br>
a ring and weld it together with m spot welder
then spot weld the rings <br>
to the handles The handles were also the feet to
hold it above the <br>
stove burner. I lost the pics of it. I had a
20KW spot welder and had <br>
traded for a 10hp Variable frequency driver and
motor from a technical <br>
school. I dropped the amperage with the variable
frequency drive to <br>
keep from burning the wires up. The wires were
about 3/16 dia.<br>
It was fun for a while, then I felt like I was
wasting my talents on <br>
crap... Machine shops were closing down here to
send jobs offshore. <br>
So, I have a building with a 36x120 lathe, a 16x84
lathe, a 9x40 lathe, <br>
a Cincinnati Mill with a 16x72 table and universal
head, 2ea Kearney <br>
Trecker mills with universal heads, another later
model Cincinnati <br>
overarm mill with a 16 x 72 table, A Bridgeport, a
couple of knee mills <br>
one Japanese, the other old old US made. I did
one job with the newer <br>
Cincinnati overarm making T-nuts for a big holding
table. Now they just <br>
sit in case I need to make a part for my old
junk. Then I was going to <br>
build industrial engines, and bought the boring
bars, head work <br>
equipment and a big big crank grinder. Never got
the crank grinder set <br>
up. It is still on a trailer and a stray tornado
took out the building <br>
it was stored under.<br>
