Another addition to the round column mill, which has been coming for some time. Flood coolant would have been too messy (and expensive) so went with a mist cooling system. This just worked with the pieces I had on hand, hopefully it can give someone an idea to run with in adapting a system to his or her machine without spending a ton of money.
As always, thanks for coming by!

Cool thank you for saying so - I've been curious how old they were after picking them up in a box of wrenches from a garage sale. Those garage sale wrenches are usually destined for the "sacrificial wrench" box in the bottom of my "work" tool cabinet - those are the ones that get heated, bent, welded, etc. for special purposes. When something different or cool like those Toyota ones come along they get saved, though. Thanks for the kind words, and thank you for the information!

That system went with the mill to mu buddy who bought it, but I will need to set up another system on the new-to-me mill once my garage is functional so I'll probably order some of this tubing like you used at that point.

Hi Everett - I bought a couple of the import type misting blocks quite some time ago - look much like the one you have. Did set up for function, using a small plastic bottle as a reservoir (smaller than yours!). It works OK, on lathe so far - but while the air flow helps a lot for chip moving the mist can be messy - fine adjustment is the challenge. Thus far have to admit I still rely pretty much still on cutting oil. One or two more tweaks on my mister might help and still get some use yet. You managed a nice adaptation on yours and the set up seems pretty nice - bracket came out well.

@EverettsWorkshop 6 жыл бұрын

Thanks, Chris - figured for the price it was worth a try. I have a second one that might get set up for lathe use with a mag base so it can be removed easily. You're right though, even being mist vs flood there is a bit of spray, but it is manageable (so far) and less messy overall.

The mist coolant system I bought was set up for the 8 mm tubing but the fitting screwed out of the body and I got one for 1/4” tubing. The body thread was a standard 1/8” NPT. Or at least a 1/4”shark bite tube x 1/8” NPT screwed right in and sealed with Teflon tape. I never really measured the thread.

It makes sense, as there is only a few thousandths difference between them, it just seems like the 5/16" or 8mm tubing is less common around here than the 1/4" and 3/8", both of which are very common in air lines on heavy trucks. Truthfully if I were to do the misting system again I wouldn't go so cheap on the components as it worked but the air demand would tax my compressor's ability over time.

Hello Canucks...it's kind of strange to me how many people are stilstruggling with imperial measurements, when so much equipment and material is sourced in metric dimensions? Maybe it's a result of suppliers still being US-based? I've been living and working in European countries for some years, and fear having to find sources 'in town' for metric parts, tools, and material sizes! And, the concept of dealing with '7/64'!! Or, is it easier than I think? Last time I was in Canada it seemed that metric hardware was 'special' in Rona and the like... is it more accessible with other suppliers? I do like the Canadian channels, like yours and Pierre's; and nice that Pierre does take the trouble to use, or show, metric measurements :-)

@EverettsWorkshop 5 жыл бұрын

Hello Lohi, yes, we really do have to have a familiarity with both systems of measurement in Canada. While the U.S. has retained the former English system of feet, inches, pounds, etc., Canada did go Metric in the 1970's. The thing is that a lot of material, both imported and domestically produced, is still in inches and feet. Like a lot of Canadians who work in the trades I am comfortable using both, and the main reason I use inch-based measurements is that the metalworking equipment I have is in such measurements. If I had found a metric mill and lathe, and similar eBay deals on metric measuring equipment, I would be using primarily millimeter-based dimensioning. I know Pierre does mention equivalent measurements in his videos, if that is something that European viewers would appreciate I'll gladly start including them as well. Thanks for bringing up a good point, and thanks for coming by!

@lohikarhu734 5 жыл бұрын

@@EverettsWorkshop thanks for your pleasant reply :-) as a 'former' Canadian, I knew that Canada had adopted metric, but I'm surprised how prevalent imperial ism still... I do get it that most older equipment, or purchased from the USofA, has imperial units built in, so that many of us 'home shop' folks will have that dilemma to deal with. Strangely, my 1930's German lathe has some imperial threads, including the compound feeds :-( , but the dials on the compound are marked in the closest metric markings possible, e.g. .08 mm, actually .079375, but 'close enough for government work' ;-) but, I do love not having to mess with fractions, and the associated strange thousandths, or number size screws and drills! Have a loveky weekend, sir!

@unionse7en 5 жыл бұрын

The air and oil pressure before the needle valves need very little psi needed around 3-15 psi....the needle valves will adjust the pressure drop even further. If one uses high final pressures you will get fogging., because of the resultant high air flow which will atomize the droplets far too much........i.e suspended particles that float in the air....you don't want that you want larger droplets (they will still be very small to the eye), these droplets are than carried by the airstream and land on the target instead of floating all over the place, including your lungs. ALso on the HF regulators you can install much lighter springs for more sensitive adjustment, The needle valves that come with the chinese misters are also quite standard CLippard makes much finer needle valves. Adjustments can take some time , ant it can take some time for the system to purge when initially turned on, so I find the better for automation when things can continue running repeatedly.

Hi Sergio, I wound up getting an 8" (20cm) rotary table because it was a good deal. It was (and still is) missing a few parts I need to make. If you're not doing large objects on your mill then a 6" (15cm) rotary table would be more convenient for a mill our size, as I find mine sometimes a bit big for general work given the table size. For what I do, it is sometimes handy to have the larger diameter but it is often a tad big. The 6" with all accessories also tend to be more affordable than even just the bare 8" table, so that is a consideration as well, I just got mine used for cheap. Merry Christmas and Happy New Year to you as well!

Hey Craig, in retrospect that would have been a better idea than to make it bolted down. In fact at some point it will probably come unbolted and mounted to a magnet as you say.

I would do something with more positive colant flow so you can use a slower air stream if you're designing one for yourself. Definitely get the budget nozzle though, they're a good price but you just have to have some 8mm line to go into it or make a fitting like I did.
