@GameChanger, great video.
Approximately by the end of this week barring any complications like the tornado that hit my property 2 weeks ago.
That isn’t your creation but it looks close and I see he doesn’t have enough liquid to cover the second hole.
So why does our second hole need to be submerged and what happens if it isn’t?
I believe it’s about the PROPER lubrication @Dan_the_Man.
The Teflon bushing is just below the vent hole on all of them regardless of make or model. On mine that is one inch from the bottom of the tube. The liquid will lube it at that level. When running there is a strong suction that will also do this. My advice has been that it is best that the hole be submerged but to never run without a one inch liquid depth and to never run it outside of liquid when dry. PTFE or Teflon (trade name) has the lowest coefficient of friction of any suitable product and will withstand over 400 F. I have ran the bushings dry for test purposes and it took awhile before any damage was noticeable. While it is very slick and chemically resistant it does not have strong mechanical properties like many others. Like many things, there is a trade off. Others are mechanically strong but not suitable because they will not withstand even half the temps as Teflon.
I need to take the time to write a users guide to clarify these things and as yet have not. I apologize for this and will get to it asap. I did lose some time with a family emergency and also from a tornado. I have many people anxiously waiting so have tried to focus on that.
The 6 holes at the bottom of the tube are ports for the liquid to exit and I refer to them as the stator ports. The high speed rotor inside shears the liquids particles while developing high pressure inside the mixing chamber which forces the liquid to exit the stator ports. The Teflon bushing blocks the liquids from being pulled upward though has a very small clearance for lube purposes.
The larger holes are vents. The hole one inch from the bottom is to allow any liquid that finds it way through the Teflon bushing to not be pulled up any further and to also provide drainage . The top vent hole about 4 inches from the bottom performs a similar function but is mainly to counteract any suction that would develop above the Teflon bushing and allow drainage of liquid. The first vent is more often than not submerged.
I will publish a user guide in the vendor section and post notice here.
Thanks for the very detailed post @GameChanger, and I hope everything is OK in regards to the family, as well as the whole “tornado” thing. I can only imagine.
Miraculously there was not much damage to my home and shop building. I had several downed trees and things blown everywhere. It even blew a glass table off my deck and toppled my wrought iron grill. It was a hell of mess but I know I was lucky. A cornfield next to my property was flattened with stalks pointing in every direction and you could see the tornado’s path where it touched down. Apparently it lifted up and went over my home.
It seems someone was looking out for you. Glad you’re OK. I’d bring over some beers if I was local.
As much as I am anxious for one, you take care of whatever you need to attend to. We can wait. I hope you didn’t experience too much property damage and everyone is OK.
Thanks bud, all is well and the lathe is turning
Whew, that’s a relief eh? Tornadoes are like those little rubber balls, they bounce.
Thanks for the info on the strator holes and the vent holes. I understand how it works a little better now. The whole shearing of liquid particles is amazing to me.
Absolutely dying to get my hands on mine. I convinced the fiancee that it was a necessary purchase along with the black n Decker RTX super excited. Glad to hear your house is okay @GameChanger
How far down the wait list am I?
What size cylinder do you use for 10ml SFTs?
I’ll check when I get home tonight and get back to you.
Ok, So the one I have is a 25ml graduated cylinder with an ID of 17mm. Here’s the catch. It won’t work for 10ml batches. I use a longer ProScientific probe for those. The game changer is shorter and you would have to go to 25ml batches to get it deep enough into the liquid to work properly.
Ah… good to know thanks Walt. Had been looking at purchasing a couple of 25ml cylinders. Are you using anything thing else for the 10ml batches?
Might try Polypropylene cylinder and cut down to size
Sounds like a plan. The only thing I use is the 25ml cylinder with the longer probe. It’s handy.
