I think the best and cheapest for alu would be the 91% isopropol in a 
mister, running pretty close to dry. If there's runoff, turn the mister 
a little leaner. Since some of us are pretty good with electronics, aim 
an ir thermometer at the bottom of the mill, and use its output to 
regulate the mist to hold it below 70F.  That should go easy on the 91% 
and make it an affordable sub for oil or water while leaving it pretty 
dry at the same time. I fact I'll go looking for something that could be 
adapted. but the pickins are slim so far.

Don't go to the pharmacy, go to the paint dept. of the 
hardware store, they have isopropyl, denatured ethanol, 
acetone and methanol in quart cans.  But, running such stuff 
in a mister is going to require serious ventilation of the 
shop or the fumes will accumulate.

Hi Jon,
Wow, who would of thought? I bought the same lathe(15) in 
an auction last year. The reason for building that rotary

Yes, same for me. I had a toy lathe and really learned 
that rigid was very important. I researched before bidding 
and word was that this is about as good as it gets.
There are certainly a few other lathes in a similar class.  
LeBlond tray-top, Monarch, and some of the other 
toolroom-grade machines. Since the standard version has a 
1250 RPM spindle speed, and a 2.5" spindle through hole, it 
seemed like it would do most anything I'd come across.


Looks like you have the high-speed version.

I run mine off a VFD with braking resistor, this gives me a 
pretty quick dynamically-braked stop, which I like for 
safety reasons.

Dry ice is cold enough it could cause warping, or just throw

I use a water-based coolant, and when things get hot, the

Yep, its downright crunchy out, about an inch of snow on the ground, and 
2F right now, forecast for -5F in the late wee hours, 2F short of 
setting a new record. Power has been iffy, my 20 kw auto nat gas has 
fired up 3x in the last 36 hours. Too cold to be slick but these people 
couldn't miss a power pole if they tried. This, as long as I'm dressed 
for it, doesn't bother me a heck of a lot, but I sure feel sorry for the 
locals who've never walked by a thermometer nailed to a tree that 
said -39 while I was looking for something that would run to take me to 
the top of the hill and put the local tv station on the air for the day. 
years ago, 61 Stude Lark, battery was about 18" wide, 58 chevy St Wagon, 
same story, that left my hunting truck, a 52 ford I'd swapped engines 
in. full of 50 wt oil. 12 volt battery pushed the frozen oil out of the 
way and about 3 minutes of cranking, had it running on 5 or 6 of its v8. 
Tranny oil was frozen solid, took a minute to get it into reverse, 
backed it out, another minute to get into low, groaned down my 90 yard 
driveway to a bridge across the ditch to the main road, not steering at 
all well, hit a dry spot about half a mile toward town and found I was 
pushing one front wheel, bearings full of Pactola Lake water, then it 
broke loose and another half a mile still in low at 500 revs listening 
to dry rod bearings & wondering if the pan was gonna be big enough for 
all the pieces. Suddenly the rod bearings shut up, and the oil pressure 
guage started creeping up to about 15 psi, it had warmed up enough the 
oil pump could move that 50 wt.  Got it into 2nd gear and kept on toward 
Skyline drive and kota-tv transmitter in Rapid City SD. Was about 5 
minutes late getting it on the air.  I think that was about as cold as I 
saw it there in a decade.  So this -5F in the morning isn't much for me.  
My biggest worry is the poor circulation in my diabetic feet, frostbyte 
and gangrene could cost me my feet if I was dumb enough to go out and 
stay out.

Too bad w can't trade about 15C, you could use the AC and we could use 
the heat. ;-)

It was 45°C when I was out on the farm last Friday, fortunately a one
off, and better than the 48.9°C further inland. I did read that the
temperatures had doubled the state's death rate for the week, so you're
right about the effects. Evaporative coolers can drop the temperature by
more than 10°C for little energy expenditure, which is right handy at
those temperatures. But we're on tank water out there, and even 100
litres per day extra consumption is problematic. The neighbours were out
of drinking water more than half a year ago, all our dams bar one are
dry now, and it's 4m down to the water in it. (Must admit though,
there's a subsidy on trucked-in water, and a truckload would last all
summer.)

The plan is for solar powered aircon and plenty of insulation when the
new build gets that far. When PV power is cheap and water is scarce,
conventional economics go out the window.

Let's hope the frigid vagrant polar winds up your end of the planet
are temporary. They're even more lethal, I figure. It's unfortunate that
they're pushed south by polar warming, as that's happening twice as fast
as the global average, so there'll probably be more of it in the coming
years.

Thats another good idea.  But my local iso booze pedlar CVS would surely 
want to know what it is that I am doing with all that 91% I'm using. :)

I'd have to find a place to buy it in gallon cans.

Lots of people use K2 for EDM, but I've found distilled water works even 
better here.  And no fire hazard at all. ;-)

Thanks Greg B.

Thanks, that was it. 

Now the next question is about field outputs in the d version. I have 
been using charge buckets to detect the 500 hz square waves, gated from 
the charge pump to enable, in sequence determined by timers in my hal 
file, to enable a couple 400 volt 30 amp SSR,s that turn on the spindle 
supply first thru a 50 ohm 200 watt R, then 4 seconds later, turns on a 
second such SSR that bypasses the 50 ohm. This to control the inrush 
that if hard switched, trips a 30 amp breaker.

If I clip out the charge buckets, and simply ground the - terminal of the 
SSR with the timed outputs while feeding the + terminal 12 volts. is 
there ever a situation during the systems power up where those 2 outputs 
might be pulled down, enabling things out of sequence or the timers 
control?

If its safe, I can simplify the hal file by at least 15 LOC.

Talked to you on and Catherine the phone just now. So that potential 
problem is solved also. Thank you.

Begin Greg --
The Tool and Die crew I worked with would use  a Ranque-Hilsch vortex tube, or 
mister on the machines in the die dept because none were rigged for flood.
One of the favorites was to mix up a 40% Isopropal alcohol with distilled or DI 
water and run it in the mister. The Alcohol really boosted the evaporative 
cooling. When the job needed extra chill they would run 95% Isopropal. Only 
time it would ever catch fire was when OD grinding 1mm dia. ejector pins. It 
would light for maybe 2-3 seconds, but could never sustain its self.

I would use an inline pressure regulator and keep the pressure down around 
25psi to help keep your compressor from having a heart attack.
On gummy AL I have made a 1/4" mote around the work area on the panel and used 
a small squeeze bottle to put just enough Kerosene on the part surface to see 
that it is .02" deep and as it leaks away through the cutouts I add more as 
needed, (running 4K-24K RPM) I also highly recommend Kerosene for use with "D"

I think that my little Minor might win on the "disproportionately deep and

Hi Jon,
Wow, who would of thought? I bought the same lathe(15) in an auction

Yes, same for me. I had a toy lathe and really learned that rigid was 
very important. I researched before bidding and word was that this is 
about as good as it gets.

Best, Dan.

Being a good shade tree guy I have rattle cans of it, big ones. I'll give 
that a try on the next one, and see if I can re-enable the pot so I can 
slow it down.

Peter;

I got one of the panels cut, stuck a line cord gland and a line
cord feeding a 5 volt and a 12 volt supply for field power, hooked
it up. But I see no hints of the 7i76 in the dmesg or halmeter
menu's.

So I poked at it with mesaflash, again w/o finding much. Asking
for --serial, I get:
SSLBP VERSION 1.43
SSLBP CHANNELS 4
SSLBP baud rate 250 kilobaud.

I've put the 5i25_7i76_1px2d.bit file in the 5i25 in the G0704's
Dell. And I do see a #1 pwmgen out of p2.

Shouldn't I be seeing more evidence of the 7i76? I've no clue how
to address it in the .hal files.


Yes, but you need field power (say 12 or 24V) on the isolated I/O
section ( orange connector) for the 7I76 I/O pins to show up


It has 12 volts (assuming all such marked pins are paralleled), and
both amber leds are on, and w1 is set for separate supplies.
Available current is only 1.25 amps from that rather teeny supply.
Verified by DVM.


Power TB1 (Orange) from 12v (+12v on TB1.1, 12Vcom on TB1.8)
Move W1 left and it should work


Slight improvement. The rear amber led is not quite as bright as it was.
Did a full powerdown on everything, moved the jumper toward the db25 &
booted it all back up.  Now dmesg says:

I can sure confirm that! Whatever it is, is a show stopper. Quite a few 
holes, first one cold is fairly neat, but it all goes to pot for the 
next hole a bit over an inch away.  Wet or dry.

Slight improvement. The rear amber led is not quite as bright as it was.

Re: [Emc-users] cutting thin alu panels problems, was 6040 problems

[Stuart Stevenson]

I would run at approximately 8000rpm, 20ipm and add lines to the program to
helical through the part without returning to center and the last trip
around would be just circular instead of helical (this last is not
particularly important).
I think you are running the spindle too fast and not enough feed for soft
aluminum. I would do the same for soft brass/copper.
Flood coolant or mist coolant either way would be just fine. WD40 is a
great cutting fluid for aluminum. May fog the shop in a mist sprayer. Get
an aerosol can and try it while cutting.

Oh, that's another issue!  2024 cuts great, 6061 and 5052 
with a heat treat cut pretty well.
Soft stuff like 1000 (or is it 1100?) and 3003 can be a bit 
difficult.  They tend to mash a bit rather than cut.  
Keeping these cold is a huge help, even getting up to body 
temperature starts to interfere with the cutting!

Peter;

I got one of the panels cut, stuck a line cord gland and a line cord
feeding a 5 volt and a 12 volt supply for field power, hooked it up.
But I see no hints of the 7i76 in the dmesg or halmeter menu's.

So I poked at it with mesaflash, again w/o finding much. Asking
for --serial, I get:
SSLBP VERSION 1.43
SSLBP CHANNELS 4
SSLBP baud rate 250 kilobaud.

I've put the 5i25_7i76_1px2d.bit file in the 5i25 in the G0704's
Dell. And I do see a #1 pwmgen out of p2.

Shouldn't I be seeing more evidence of the 7i76? I've no clue how to
address it in the .hal files.


Yes, but you need field power (say 12 or 24V) on the isolated I/O
section ( orange connector) for the 7I76 I/O pins to show up


It has 12 volts (assuming all such marked pins are paralleled), and both
amber leds are on, and w1 is set for separate supplies. Available
current is only 1.25 amps from that rather teeny supply. Verified by
DVM.



Power TB1 (Orange) from 12v (+12v on TB1.1, 12Vcom on TB1.8)
Move W1 left and it should work

Drawing the outside edge of the tool in a circle, dropping the plug in 
the middle most of the time, with z feed rates of about 10 thou per trip 
around the circle.  Panel is soft alu, about 80 thou thick.

The subroutine used:

( arguments passed are #1 tool_rad, #2 holerad #3 xloc, #4 yloc, #5 feed 
rate)
o130 SUB
G40
F#5 (feed rate)
( MAKE SURE IT CLEARS )

G1 F5 x#3 Y#4 ( back to center of hole slow as full depth cut in case

G0 Z#<_ZUP> (back to clear)

ZUP is about 40 thou above work, ZDN is about 30 thou into the spoil 
board. Cherry in this instance, came from the scrap pile behind the chop 
saw.

It has 12 volts (assuming all such marked pins are paralleled), and both 
amber leds are on, and w1 is set for separate supplies. Available 
current is only 1.25 amps from that rather teeny supply. Verified by 
DVM.

Are you cutting holes from solid or cutting the periphery of a shape?

Subject: [Emc-users] For PCW

Peter;

I got one of the panels cut, stuck a line cord gland and a line cord
feeding a 5 volt and a 12 volt supply for field power, hooked it up. But
I see no hints of the 7i76 in the dmesg or halmeter menu's.

So I poked at it with mesaflash, again w/o finding much. Asking
for --serial, I get:
SSLBP VERSION 1.43
SSLBP CHANNELS 4
SSLBP baud rate 250 kilobaud.

I've put the 5i25_7i76_1px2d.bit file in the 5i25 in the G0704's Dell.
And I do see a #1 pwmgen out of p2.

Shouldn't I be seeing more evidence of the 7i76? I've no clue how to
address it in the .hal files.


Yes, but you need field power (say 12 or 24V) on the isolated I/O section
( orange connector) for the 7I76 I/O pins to show up

Google Translate did the best job so far. But it prints a letter sized 
page in landscape format, clipping off the bottom 1.5" of the page, w/o 
carrying it over to the next page. Its better than nothing and did get 
me usable English. Incomplete of course because of the page clipping. 
Changing the portrait to landscape in the printer dialogue has no 
effect. I did 3 copies of that 64 page thing trying to get a portrait 
mode printout. Since that printer can do up to tabloid, 11x17 output, 
that might have worked but I'll be dipped if I'm going to feed 64 
tabloid sheets thru the hand feed slot in the back of the printer. Sheet 
alignment is very critical, and I've made a feed tray but theres nothing 
on the back of the printer to give it a fixed alignment to the feed 
slot. Right Pain In The Ass is what it is. I have used it for rockhopper 
printouts though. They can usually be fitted to about 8 sheets of 
tabloid.

Watch the heat down there Eric, I'm hearing reports of above 40C from 
your neck of the woods. Thats killer heat.  Do what we call swamp 
(evaporative) coolers help?
