RegularRhett69 - When I originally bought this Stark M570, I had been on the hunt for a Royal M5000 in good condition for some time... and through my research I already knew that Royal had produced a number of vacuums for Stark, so I knew I absolutely *HAD* to buy that M570 as soon as I laid eyes on it. - Especially because prior to finding my Stark M570, I had only ever seen one other Stark M570 posted online! I absolutely couldn't pass up the opportunity to own part of Hand Vac History!
RegularRhett69 - Also! I plan to get those replacement bag gaskets posted online later today! - I was hoping to have them posted & available to VacuumLand members much sooner, but unfortunately I found myself much busier than anticipated this week - so I apologize to you for the delay in regards to the availability of Bag Gaskets.
CentralVacs1928 - The gray plastic fan that you saw in my video was the fan from a Dirt Devil m103. I was merely using it as a comparison to the black plastic fan out of a Royal M501/M5000, or in this case, a Stark M570. - You are absolutely correct though! The blades on the gray Dirt Devil fan ARE facing the opposite direction of the blades on the black plastic Royal Prince fans!
I never knew this until I actually began tinkering with them, but the motor in Royal Prince hand vacuums rotates in the opposite direction of the motor in Dirt Devil hand vacs... or Vice-Versa, since the Royal Prince technically came before the Dirt Devil. -- Prior to owning my first Royal Prince hand vacuum - which was actually this Stark M570 - all I ever knew was Dirt Devil hand vacs... so the first time I installed the belt in my Stark M570, I installed it like I always did on my Dirt Devil hand vacs, and it popped off as soon as I turned the motor on! After that happened twice, I tried installing the belt the opposite way, and it stayed on. So that was the first time I actually realized the motors in Royal Prince spin in a Clockwise direction & Dirt Devil hand vac motors spin in a Counter-Clockwise direction. -- Which explains why the fan blades are facing the opposite direction on Dirt Devil fans, in comparison to Royal Prince fans.
CentralVacs1928 - I actually do have two of the original Cast Aluminum fans from early Royal Prince models. I honestly don't know how much of an upgrade the O.G. cast aluminum fans really are over the black injection molded plastic fans... as I've read discussions from VacuumLand members talking about how the Plastic Fans on Royals & Kirbys are more resilient than their cast aluminum counterparts. I don't have any scientific data on this, but as far as Royal Prince hand vacuums go, I genuinely feel that the fan is the weakest part in that whole vacuum & is more likely to break than any other mechanical part in the entire Royal Prince vacuum. -- I will admit that I did install one of the O.G. cast aluminum fans in my "Daily Driver" '95 Royal Prince 501 that I use most frequently. I'm not sure if the cast aluminum fans are, in reality, weaker or stronger than the black plastic fans, but I figured I'd give it a try and see how it performs.
That being said, because I love my Royal Prince hand vacuums SO MUCH, I try to be extra careful when I'm vacuuming so I don't suck up anything that could potentially damage the fans in any of my Royal Prince hand vacs... because although I'm fortunate enough to have a couple of replacement fans on-hand, I'll be hard-pressed to ever find another replacement fan, short of buying a whole Royal Prince & tearing it down for parts. -- Needless to say, I *really* don't want to break or damage any of my Royal Prince fans... Which is why I'll often cringe when I hear the metallic "TING!" of something hitting the blades of the cast aluminum fan I installed in my 1.8 amp '95 Royal Prince.
