Ok guys, for those of you who have primestars on motors what did you use to fill in the gap between the neck of the motor and the neck of the primestar.

I drilled a hole in the side of the primestar neck on both sides to put a screw through the holes that are allready there in the neck of the motor. IT works great to keep it stable but he problem is is the dish moves up and down.
What did you use to stabelize it? Or what did you wrap around the neck of the motor to keep the dish from slipping off? Thx.

I am gonna need some better idea, Bob...I don't know what a Neck is....LOL :D

Lemme dredge up my old thread on how I did mine...

Okay here is one of them on my 1m dish: I now have two set up exactly the same right now.

http://www.satelliteguys.us/872786-post8.html

And here is my failed attempt of an 84e, it was a little too 'springy' and didn't stay aimed well. If it was all I had it would have worked, but I found another 1m dish so I took the 84e down and put up another 1m.

LMK if you need anything else. And also some other fellas will be chiming in here very soon that are a LOT smarter than me with some ideas for you, I am sure. :up

EDIT: I THINK you mean that you are using the stock primestar mount inverted, no? In that case if you don't have a 50mm shaft on your motor you're going to have to get very creative. I used plastic pipe to shim mine up. I split the pipe and slide it over the motor shaft when needed. You can also use radiator hose if you have that. I also do that when I want to put a temporary dish on top of one of my masts...

this is what i did invert the mount and used pvc pipe and cut a small section of it out... i didn't do any extra bolts through the mount & shaft for extra support but most of the time wind isn't a problem here.

What size of PVC pipe did you use.

I used 1.5" PVC.
Cut it to length, then cut in two (lengthwise).
Been using it for a couple years now.

I bought the 50mm (1.97") optional shaft for my motor. Using this table http://www.snapfour.com/pdf/Table_38-39.pdf shows 2" schedule 40 pipe has an internal diameter of 2.067". The Primestar mount I have used 2" pipe (actual dia = 2.375"). I used trinity13's method of splitting a piece of 2" pipe and slipping it over the 50mm motor shaft and then the Primestar mount over it. Further I modified the Primestar mount so it didn't have to be inverted plus I could use it's elevation adjustment.

I bought lightweight angle iron at the local hardware store, the type with the holes in it. I connectect it to the dish where the old mounting was. I used C clamps to go around the shaft and connect to the iron. I never posted pictures on here before so if someone can show me the way I'll post some pics. I think I spent twenty bucks total if that

Recognizing there's more than one way to skin a cat, this is the approach I used to mount a Primestar mount to a SG2100 motor.

I have borrowed Stogies idea. :D Hopefully he wont go after me for patenting violations. :D

What did you use on the bottom of your mount for your elevation adjustment. I went looking for something simular at 3 hardware stores and couldnt find anything that would fit the neck of my motor.

So far the mount is a keeper and alot more sturdy than what I was doing.

Ok, I didn't have the sheet metal that Stugie had But some good olé double thick plywood should do. Heres some pics. Right now I have a bolt just shimmed up there holding it up for elevation. I have to figure out an elevation solution. But I know you all want to see some pics so here you go :)

Bob you are going to have one helluva time dealing with elevation with where your pivot point is on that motor. If you look at mine the pivot point is right below the bend in the motor shaft. You may have to drill another hole higher in the motor shaft to be your pivot point.

What kind of motor is that?

Otherwise great work! I said the next one I do I am going to use 1/2 plywood and paint it up real well and see how it works. I just used the aluminum because I had it. :)

Oner more thing I see that you probably will want to do is put some flat washers behind the dish-to-plywood nuts. Over time the plywood will soften and you don't want it to move, and washers will abate that somewhat.

I ghetto-photoshopped about where I think you need to drill the hole...but then when you do that your plywood isn't gonna be long enough on the bottom to mount your elevation bolt into. Have a look at mine and you'll see what I mean...

Nahh, the pivit point is great. Its on elevation now the way it is in the pictures. Elevation is no more than 40 degrees up here in chicago. :) It can probably go up another twenty degrees or so the way it is now. I have the SM3D22. The pivit point is on the top hole for the motor. As it is now, its at the highest elevation on my arch on my true south bird, with room to spare for motor adjustments, if needed. I just need to secure my elevation and devise a way to adjust if nessasary. Right now with a screw holding it up on its own, the elevation part is not as secure.

I used a foot from the original Fortech star's mount wich was on an extended mast. so there is more room to play with than what the picture shows.

EDIT: This setup is working out great, Im getting over 75 percent quality on PBSHD On Amc3!!!!!!!!!! never seen that before :)

The way that the angle of the photo and the way it was taken it looks like there wont be enough but there is. Just barley though. I have an idea at how im going to attack this. I just have to wait untill next weekend to do so. So far it seems to be on arch, alltough I want to wait untill im fully secured on the elevation to test.

Hey, if it works, why worry? :)

The point I was getting at is if you use my method with the conduit clamp you are going to have a whale of a time getting it in there and adjusted properly, due to limited space between the bottom of the motor mast and your plywood. You need some room to work in there. :)
