I wouldn’t mount it up there over the spindle and over the spoilboard. If it leaks, that could be a big problem. I mounted mine off to the side, right where my water lines go through my table down to the reservoir bucket. I can still see it, but it’s not over the MDF spoilboard or anything electrical that could be damaged if it leaks. People like to mount it up there simply for the “looks cool” factor, just hope that it never leaks.
I honestly don't have a clue what to say, these devices are meant for visual coolness inside of fancy colored illuminated computers and protect nothing. Computer thermal protection is built-in to the CPU. Spindle manufacturers note that the max temp of the spindle before damage is 104 deg F (40C). Since many in their garage could be at 80-90 to start with there is not a lot of room for error. 10-20 degrees only takes a minute of 2. For a visual protection to work someone would have to look at the spinner every 30 seconds the entire time a job is running. Not likely possible. What is more likely to happen is you will hear a tone change when the bearings start to cook and then notice the spinner isn't spinning. I don't know many CNC operators that can or want to keep looking at a spinner, you can watch the job and the spinner at the same time. Or for that matter do any cleanup. A real flow switch is $20 on Amazon (Canada)! Used by many CO2 laser folks. Its a very common part. It does need a bit of wiring. If your pause shuts down the spindle simple parallel it to the pause button. Then manually run the pump so that there is flow when the controller starts the program. For any one of 100 reasons the flow stops the program will pause and stop the spindle and indicate its paused. If your doing something else in the shop you will hear it shut down and know your protection worked! The only place the spinner is good is when you fix the problem and re-start the pump you can see there is flow so you can re-start the job.
Great job. My career was as. An Analytical Chemist, so I can tell you that “Barb” is. Indeed the highly technical name for them. One suggestion… I would suggest that one should spend an extra dollar on a couple of small hose Clamps to put over the hoses. Tyson tubing is notorious for working its way loose over time. Can’t count the number of times I’ve seen the mess. when that happens in a lab.
Before cutting your fluid line like I did, check the diameter of the hoses. This unit won't fit on an Axiom router the lines are too small. Now I need to find a fix.
garciarosa100, I appreciate you sharing that tip! It's always important to double-check compatibility before making any adjustments. Good luck finding a solution for your setup!
Great video. I have been looking for one of these. Amazon Canada want $58 CDN for this. If I add $10 US for shipping and convert to CDN dollars Amazon US would cost me $45 CDN. There is got to be a better way.

TerrapinCreations666, very good point my friend. I couldn't agree more.
Does it matter what side you put it on??
That's a great question! No it does not matter which side the flow indicator is on.

Thanks for the input. This is a visual tool as I said I'm the video to ensure the coolant is running.

ctenos45069, thanks for that additional suggestion brother! I will try it out and see how it goes.

Good tip, question, Do you run your spindles through a chiller such as the ones used with a Laser Engraver?
cliffgeter1105, you definitely can brother! But it all depends on your spindle manufacturer recommendations and how you plan on using it.
You read my mind............. Stop that !!! LoL
danneil7806, glad you liked this one my friend.
Amazing I did the same thing.
JimPitts, glad you liked this one brother!
id clamp the hose with zip ties
hx4791, that is a good idea brother! I like that.

marklasby4613, im sorry to hear that brother. It can be tricky getting things to CNCers up in your neck of the woods.
Well done 👍👌
IceCreams62, thanks brother. Glad you liked this one.
