I love your dry humor 😂 and your channel is awesome you deserve more subs
Beter hey 🅱️eter
Thank you Walter, for all you do for the knife making community!!
I was just adding a homemade one today on my custom home built 2x72 I made as well ;) Thanks for sharing and ThumbZ UP !!!
thank u for this video. I have been on the fence about getting a kool mist. I think I will get me one now. I appreciate all your videos walter they all very helpful.
I've used a flood coolant system for a few years now (with a high-tech reservoir like yours), but this might be on the list of things to switch to in the coming year. It is excellent for micarta!
I do like them for roughing too. not having to take the knife off the belt is just awesome. Don't keep having to interrupt your concentration by cooling. I've got another one on the way for my disc grinder too although that one might be messier
I've used those mist sprayers for decades in the machine shop. They also come in a pumped version as opposed to a venturi. An added benefit is that Kool Mist has rust in inhibitors. I think you'll like it and as you realized, it really "shines" in a production environment. Thanks and Merry Christmas.. :-)
If you use spray mist, does it not damage the belt? Or will it reduce the efficiency of the belt?
I have been using a Koolmist for drilling and milling since 1997....great product and the coolant is very inexpensive...about $.35 for 8 continuous hours... I would not even attempt to sharpen drill bits on my Black Diamond drill bit sharpener with out a Koolmist.... great video Sir!!!
Nice review, thanks Walter
fantastic as usual, looks like a decent peice of kit.
Thanks as always Walter, you 'da man.
Walter,
You make learning bearable.
I enjoy your videos, and am learning so much. Now, when do I get my rear end out of my recliner and out to work? Oh, gotta mow the lawn today.... Never knew what an acre of lawn meant until I moved here to NW Indiana! So much for a retired duffer to be doing that impedes on what I WANTS to do!
Good presentation.
THANKS WALTER
Very helpful. Thanks!
always great stuff
I really like your videos. Keep it up.
Looks like the coolant nozzles used on ophthalmic lens finers/polishers. Also similar to the way we keep handstones cool (and manage lens swarf). Do you keep a chilling ring in the water supply, or is it room temperature?
I've used mist coolant on a couple of mills and lathes at the machine shop and I thought about using it on a belt grinder but was wondering about how some of the belts would hold up over time to getting wet then drying out repeatedly.
how do you catch the used coolant I would imagine a puddle of slick goo on the floor where you working
can the coolant be reused dies it need a filter?
May I ask what air pressure is necessary to run such a mist spray? I am just in the process of choosing a compressor and do not want to overdo it as I do not have any other use for the compressor. Thank you
Just curious if you have noticed much dust mitigation with this system? Does it cut down on the dust factor in any way in your opinion?
Thanks!
What psi do you run your kool mist at? My compressor stays on the entire time I grind with the kool mist running, but it's only a 6 gallon tank.
Thank you Walter for bringing this to my attention. It should work well on my KMG.
Also, I wasn't aware those 3M belts were water resistant. How do Blazes work with wetness? I am always constantly dipping and then wiping off because I was under the impression that the water will loosen the adhesive to the abrasive media. I appear to have been wrong. Thanks again :)
Also, how necessary is the coolant liquid vs. just straight water?
I solved the problem of excessive heat by switching to CBN heels on my bench grinder and use a CBN one card to touch up and maintain the burr on the edg
What belts cannot handle water sir? I use silicone carbide for some fossilized palm wood and malachite and such. I do not use anything else unless it specifically says for wet grinding.
Hey Walter, what type of sanding belt has the checker pattern in this video?
Josh Rider asked what PSI you use on the compressor for the mist, Unfortunately I cannot find your answer anywhere. Can you give us the PSI you use. Thank you
with time and adjustment u can up the air lower water flow and get it less messy smaller tip orifice fam to your side blowing mist away ... i used to use these surface grinding they are cool ...:)
i thought the gator belts are supposed to be run dry?! only reason I ask I am belt converting an old school doall surface grinder and the gator belts are awesome for that application. it would be nice to use my koolmist on the surface grinder with those belts if I can.
I heard that Gator belt shouldn't be used with water. How do you think?
If you use spray mist, does it not damage the belt? Or will it reduce the efficiency of the belt?
Does this help getting more life out of your belts since it seems that the coolant would flush some of the metal from the belt
will this help with dust control?
Does the coolant you mix with water do enough to justify buying it?
What was the speed of the belt with water after heat treat??
Have you ever tried this with ceramic shredder belts?
What kind of belt is that? The blue one with all the pads on it, do they last as long as they look like they might?
+Eddie Bausch It's a 3M Trizac "Gator Grit" belt. They do last a long time but can't be used for heavy roughing. They get ruined very quickly if you really crank into them hard. They're fantastic for finish work, though.
+Walter Sorrells Thanks for the quick reply and info. I have a few Trizac belts but the pads are much smaller. I'll keep an eye out for the Gator Grit belts. I have really enjoyed your videos and they played a big part in getting me started into knife making.
does one need special 'wet' belts for this?
Does the mist coolant hurt the motor?
GREAT IDEA I WAS IN THE BELT BUSINESS FOR YEARS IN THE UK MOST PEOPLES DEFINITION OF WET IS TO HAVE GALLONS OF WATER CASCADING ALL OVER THE WORKSHOP WHEN YOU EXPLAIN YOU ONLY NEED A DRIBBLE OF WATER TO DO THE JOB CORRECTLY YOU GET A LOAD OF BLANK LOOKS LOOKING AT YOUR VIDEO YOU COULD PROBABLY REDUCE THE FLOW EVEN MORE
could I start out using a belt sander
nice i have fitted mine with a aquarium pump since i dont have access to a compressor
Hey Walter,
its been a few years since you made this video. How often, or do you even use the cool mist anymore?
Lol being that you don’t see it in other videos...
Can you use water instead of cooling fluid?
Seems like another benefit of this might be cutting down on the dust produced.
That "buffeting" problem, maybe you could get a spring loaded ball valve and make a peddle to shut the air off for a second?
I approve of this channel.
I set up a water mist straight off the garden hose,i bought the heads at Lowes for under $2 each.They can be found in the garden section.The 1/4" hose can be found in plumbing section.$20project
Good idea, i was wondering about just building one and skipping the compressor
That's like hooking up a misting system up on a patio without a high pressure pump and running it straight off the hose bib. I'll kinda work but it'll do a much better job of making a big mess.
You have to have high pressure to make it run correctly.
This might be key when using a 2x42 grinder. May have to give this s try it
.?!+
I've used industrial saws and mills that used this type of cooling before but never thought of adapting it to my belt grinder. Do you notice an increase in belt life or speed of cut?
+Michael Wheeler Not really. But I'll have to use it for a while longer before I can really tell for sure. My impression so far, though, is that the main benefit is just heat reduction.
Thanks for your time and your great content.
Just a couple of thoughts on the plus side... 1, surely this helps maintaining the grind angle if you don't have to keep dunking? 2, will the mist help as a lubricant and clear the grit on the belt, also adding more life to the belt ( similar to when using wet and dry)?
Thanks for another brilliant video... and Merry Christmas from over the pond.
Wallter, are you still using this thing?
if I stick a magnet to my grinder won't it collect all sorts of iron dust?
Richard Boerman depends on how strong the magnet is, but I'd like to say yes
LittleMachineShop.com has a variety of these systems and the tools mentioned in these videos. Pretty good folks, great help if you have questions.
How long does the coolant reservoir last?
+BlueButtonFly Let's put it this way...I haven't added coolant since I first started using this. Hours and hours and hours.
So, why not put the quench bucket higher up on the right of the grinder? No more bending over!! This is called ergonomics. Cool mist is interesting!!
Regards, Matthew
it also serves as a dust collector so you would have to have 2 buckets standing around
Wait Walter was wearing something other than his typical blue denim shirt, he had on a sweater, so he does have other shirts...
wouldn't the mister make a mess, slick floor, etc. other wise looks like a great setup. thanks
Idk I would like to know that myself... Also does the liquid contain rust inhibitors or something like that?
+ron newton as much as when youre dunking the blade in a bucket anyways.
A livestock mister would work about the same for a fraction of the price. Just mount it and run it off a garden hose.
Platen chiller by Nathan the Machinist on Bladeforums, no mess.
+gimmejr The platen chillers are brilliant, but the blade will still overheat.
The platen chillers are great for belt life. The kool mist will keep the actual blade cool.
You're a funny funny man.
why not just a cheap water pump and 1/4inch tubing?
I'm 13 years old and I want to get into my thinking what do I do and welding
I just saw you on bored paracord. I'm 14 and started making knives the year it's quite fun
How does this help me at all
+Tristan Bowman wow someone does not know manners. Simply acquire an angle grinder and good steel like that from an old saw blade and cut away without over heating. Then using a flap sanding disk out a bevel on it. The continue however you want. Not how I do it but with limited equipment that's what you can do
For welding your on the wrong Channel look for some welding channels on yt
+Josh Cohn a simple 75x533mm sander like the hand belt sander by makita and bosch are good enough, that's how I started, not exactly proficient, but you can get some good results with some 40 grit zirconium and higher grit cheap aluminium oxide belts. but you're srock removal and rough grinding belt you will want to last abit longer and be good quality, like i said zirconia in small belts is you're best choice because as far ad i'm aware, ceramic isn't easy to find and even when you do, it's deffinatly not zirconia priced as their custom. :)
Why is you voice so smooth??!?!
Or just move the dunk bucket 🪣 closer so you don’t have to bend
Do you foresee rust being an issue? That bottle of machinist's coolant will help but I imagine most knife guys will just use water.
This dude has a sexy sounding voice.
You dont even need an expensive compressor, look for an old refrigerator and use the motor that is in it
So...a compressor?
+lazaglider LOL that's funny right there.
+happymark1805 Using a 1 gallon garden sprayer will probably do
+Adamast that meight also be a good idea
+happymark1805 fish tank pump, bucket of water and a nozzle.
That was a 'cool' review
lol burn your finger and curse it why little copper thing need love dont hurt it feeling
Thanks as always Walter, you 'da man.
