  In the end I think any ratio would probably work. I haven't needed any more solution yet to try other recipe. One person posted previously that if they used 50% propylene glycol (PG) and 50% vegetable Glycerin (VG) that the diamond powder stayed in suspension. This is a common vaping configuration recipe. Propylene glycol(PG) and di-propylene glycol (DPG) are a type of alcohol which are used as a viscosity reducing agent and aids in keeping powders in suspension. DPG is considered safer and used in cosmetics. The other idea is you want to keep a bit of tackiness so it holds the powder onto the strop when it dries. Glycerine or vegetable glycerine would help keep leather soft but you don't want so much that it starts acting like a sticky sugar and holds more dirt and steel on your strop. The glycerine would tend to cause spray bottle nozzles to clog up. Next time I try it I might just use straight humidor solution since it is 50% water and 50% PG. Nothing to mix but it would end up costing a little more to make the solution. Also if you use different diamond grain sizes, add a different food colouring so you know which solution is which grit.

  I use my diamond spray solution on 1x42 leather belt and a flathone scissor honing pad. When using the solution on the flathone for hair shears on a felt pad, the scissors would get hot enough that the propylene glycol would crystalize and form a hard shell on the metal. My last batch I have changed my recipe to the following 2.5 oz distilled water 2.5 oz of Di-Propylene Glycol 3-5 cc of Camellia oil 25 CW = 5 grams monocrystalline diamond powder. I added the oil because I wanted a more softer media that would that tend to move slightly in the direction of some of the diamond pastes. This isn't a paste but it keeps a diamond solution on top of the felt pad stropping media. I use camellia oil because it is what I have on hand for knife coating and scissor lubrication. So far this is working extremely well. I also notice the solution is keeping the diamond powder in suspension much, much better. It spays out on my work surface as almost a sort of light thin foamy appearance. Maybe I should have use 3oz water to 2 part Di-Propylene Glycol. But it is definitely better than using the propylene glycol product.

  why not just add the diamonds to a light leather conditioner like lexol or bicks instead since that is designed to soak into the leather and has leather appropriate oils and waxes and glycerine etc.

• 
  @toddbenko67016 ай бұрын

  Everyone had different ideas of how they want the diamond crystals become cutting agents. We use this approach because the diamonds are sprayed and remain on the surface. We want the solution to be able to evaporate and expose the diamond edges but also to be held sticky enough so they don't bunch up or scraped away by the stopping action. I use mine either on a 1x42, 1x18 leather belt in a belt grinder or on a flat leather strop. The spray on solution is to apply a new top coat of diamond crystals. The diamond paste configuration is similar to your concept. It is used to build a base foundation on a strop. Both are acceptable but basically two different intentions. One is base foundation, the other is surface retreatment.

  I don't know. You would have to open up the housing and validate. It should be a split pole motor with a run capacitor just like a bench grinder. Only little use a magnetic tap in the motor winding in place of a cap to produce the phase shift. I leaf blower requires more torque and hence is why I think it should have a cap.

  Does this produce more heat on the motor at low rpm?

•

  The motor does get warm but how much really depends on how you use it. When I used my grinder @1750, and I really ground things down it would also get warm. I think the motor is still cooler running at 1000 RPM with more torque using the VFD than if I bogged down the 1750 down to 1000RPM because the fixed frequency original configuration only has current to make up for the speed reduction. The benefit of being able to set the speed slower or faster depending on the task is totally worth it for me.

• 
  @prairieedgeservice9 ай бұрын

  In high torque applications like you are using you should use a VFD like the one I showcased but actually use a 3 phase motor. You want and need the three phase windings in the motor to provide the torque needed, especially if you are slowing down the motor. A VFD will give you speed variability but if you exceed the torque of the motor with the electric current you will still end up burning out the windings. 300 RPM is really slow to and high torque at slow speed can cause the windings to burn out. For these type of applications, I would recommend some form geared down drive system. A VFD might help prevent your concrete agitator to prevent burnout but you would have to test to validate. The soft starts with the VFD would help control the high in-rush starting currents when under load. Can't be sure that it would fix your issue though.

• 
  @prairieedgeservice10 ай бұрын

  The capacitor causes a phase shift for the second winding. You didn't identify how you would connect the VFD to the motor in that specific case. If you are connecting the VFD to the two phases then you are causing two outputs to be tied to the same wires as the capacitor. You will likely damage the output transistors of the VFD. But if you are like a college classmate of mine, he would purposefully bought polarized capacitors just because they would blow up when connected to an incorrect power source. Deviations from my proposal are yours to figure out. I only present the findings of my own test.

• 
  @prairieedgeservice Жыл бұрын

  Nothing that I know of. Using a split pole single phase motor under normal configuration will also get warm for that length of run. Because there are additional inefficiencies when using the 3 phase VFD, the motor will get warmer. If you are thinking of using a motor continuously for 5 hours, I would recommend getting a proper 3 phase motor.

• 
  @cdrive57578 ай бұрын

  You can reduce motor heat on any electric motor (regardless of its phasing characteristics) by use of an auxiliary fan. In fact,.. this rule applies to DC motors too! Most shop grade motors utilize Totally Enclosed Fan Cooled (TEFC) motors. These motors are designed to keep shop grit out of the motor. Because of this a small fan is attached to the opposite end of the motor's spindle. When the motor is running this fan moves air across the outside of the motor housing. Unfortunately, when a VFD slows the motor's RPM, that little fan slows down too! So it's now moving much less air. When I converted my Midi lathe to 240VAC 3PH VFD drive I ran into the same issue. As a result, I attached (separately powered) muffin fan to the back end of the motor. Wakodahatchee Chris

  @@mustafadudde Uh, the reason for that seems obvious. Besides, a motor driving a lathe is going to have very low speed demands that an air conditioner's air handler will never experience. PS: After re-reading your original post I now realize that my response was less than ideal in your application. On that note, most modern VFD's can be programmed to increase or decrease torque. This "Torque" setting does increase or decrease power consumption at a given speed. To the best of my knowledge Torque perimeters are adjusted via PWM superimposed on the variable frequency. The Torque settings are very useful for air movement applications, where torque demands are relatively low.

• 
  @prairieedgeservice Жыл бұрын

  First of all validate your type of induction motor. Many induction motors on drill presses have a starting capacitor which is linked to a centrifugal clutch. If you start up the motor and hear a defined click sound, it will have this centrifugal clutch system, in which a VFD probably can not be used. The secondary windings on these motors are not designed for sustained current application. If however you don't hear the click and you open up your induction motor and find only 1 running capacitor then yes you should be able to connect a VFD. If that is the case, I believe you will want to look for a VFD with 210-240V input single phase and 210-240V output in three phase. Now if your motor has the centrifugal clutch, I would look at just changing the whole motor with one one of the Vevor sewing machine motors that already comes with it's own VFD. you can get them in 550W 3/4 HP or 750W or 1000W versions. Because of the motor speed variability (~400-4000RPM), you could probably simplify to just a single belt pulley ratio. You just have to manage the motor mounting configuration. I use these type of Vevor motors for my 1x42 belt grinder and are great! eur.vevor.com/ac-servo-motor-c_11222/sewing-machine-motor-220v-550w-brushless-energy-saving-servo-motor-industrial-p_010409180232
