I wouldn't guess that Rick's doesn't sell kock-offs. More likely he gets a break on quantity.
The owner of Von Weise in Mexico was very nice to talk to. In my book they make the Cadillac of actuators.
But he does not keep a stock of satellite actuators, rather builds to order. And I was offered a quantity break.
Great idea for a group buy.
There are several factors involved in mechanical things out in the weather. My Superjack has lived its cat lives because I value my hard-earned money. And a bit of a geeky mechanical/electrical/electronics dude.
The accordion boot is a great thing to have. Of all of the Saginaw, Venture, rebadged ones by the name of Houston Tracker. All of the screw tubes are gooked full of rust and caked up grease. Any grease in the geartrains looks like old wax.
I stand by my Zerk screwed in the tube, shallow by a few threads. Extend it fully once a year or so and give it a few pumps of Lucas super low temp grease and I'm good to go. Stick the motor/gearbox on the bench every so often and clean and grease it. New brushes if it needs it. I get mine from Ace. Closest size a bit bigger and sand them to size with a dial caliper to keep track.
Those Venture 18 inchers. I have 2 here. Dispose-a-jack. Seriously.
The dish retracting in the wind. Wow! I've extended the tube mount on my 'glass 12 footer with angle iron and bolts.
I use almost all of it's 36 inches from 127W all the way out to 30W. The dish originally uses a 24 inch tube.
It takes its sweet time traversing the arc. But when it stops. It stops. With a pull-back spring and cable to take care of over the center "flop". Longer fulcrum, less weight for the actuator, gears, and motor. And probably the dish mover current draw.
I know before when it got 0 or below. She would grunt heavy and give motor errors. Now? History.
I have dagger wounds and stone welts from people with disposable income telling me there's no need for grease or periodic PM. I guess our common sense clashes.
Here's my offer to the geeks with boxes of parts. A dynamic brake that will stop that motor cold in its tracks. It may not keep wind from moving it (you need to solve that). But it will Definitely cure a heavy load retraction of the tube when the motor stops. And absolutely help with accumulated mover count errors when you "bump" the dish to locate and store satellite position.
The relay is a DPDT mini relay with 10A contacts and 24 VDC coil. 10A is overkill but what I had in the box.
R1 can be a 1-5 ohm 1/2-1 watt resistor. Or a .33 ohm emitter resistor from an old solid state amp.
Mine is just a short. I don't need no steenkin' reesistor. Seriously. No ill effects from not having R1.
R2 is a current limiting resistor. In case your dish mover delivers considerably more than the 24 VDC coil rating.
My brake has its home inside of the gearbox cover. Fits real nice.
