Advice Needed Channel Master 1.8m On Jaeger 1224 ?

[moonbase]

Hi,

Does anyone know if there was an "off the shelf" adapter plate to mount a channel master 1.8m dish onto a Jaeger 1224 motor? The adapter plate provided with the Jaeger 1224 was for a channel master 1.2m dish and is not capable of accepting a 1.8m channel master dish.

Moving on to a related point, is a Jaeger 1224 able to cope with a channel master 1.8m dish, it is quite a heavy dish?

Last point, if there is no readily available adapter plate and a Jaeger 1224 can cope with a channel master dish, would anyone please be able to provide details of how to get the dish onto the motor? I am guessing at a 4mm steel plate cut to size to accept the 4 bolt threads from the dish, followed by two vertical strips of angle iron to get the plate onto the upper and lower plates on the Jaeger 1224?

I doubt that is a good idea. The CM180 dish face is about 45 kg, the CM120 is only about 10 with arms and all.
The windloading will be substantial, and the operational wear will be excessive.
I would not recommend doing it, although I am sure it can be done using an adapter. If you want to try without too much metal work, you can use 65 x 65 cm plywood sheet as a temporary adapter for experimentation.

Plywood needs to be about 20-25 mm I would guess.

Hi moonbase, I would get the correct item for the job a 1.8 mount, any bit of wind it will be moving all over the place, get a strong wind and it could leave the mount and do some damage/kill someone.

They do sell an adaptor for 1.2 cm to 1.8cm but I would not trust it, there is a thread on here somewhere.

I wouldn't do it... I would consider putting a Laminas 1.8m on the 1224 because it's much lighter than the Channel Master and even then I would do work to reenforce it beforehand.

Satellite Superstore do pukka polar mounts for the Channel master now, but not cheap.

 

[samoloko]

there Is laminas polar mount for 1.8 laminas which Is suitable to use with Channel Master 1.8 but you got to do a plate

 

[samoloko]

I doubt that is a good idea. The CM180 dish face is about 45 kg, the CM120 is only about 10 with arms and all.

are you sure

The dish will weigh approximately 33.8Kg

Without checking st1 would be about right, 33.8Kg was only a rough guess of the top of my head samoloko.

are you sure

hi samoloko. please refer to this old CM 1.2M datasheet page 2 which lists weights/dimensions. For reference the 1.2M reflector only for RX-only model (the tx/rx versions are heavier) is 15.2kg (33lb).

Hi,

Thank you for all your replies, it looks like the Jaeger 1224 in not an option.

I have a heavy duty Precision polar mount that is OK for at least a 1.8m dish. It has the three bolt points that are used by the Precision ring on the back of the Precision dish. However, I can use an adapter plate to get the 1.8 channel master onto this then use a 24 inch QARL SuperJack that I got with the Precision polar mount.

I think Crossbones did a mod with this a few years ago on a 1.8 CM, it looked the business .

Would be interesting to see results of your idea. But, before you make adapter plate and erect CM1,8 on Jaeger 1224, just conciser picture attached.

I have abandoned the idea of mounting the 1.8m channel master onto the Jaeger 1224. I have a heavy duty Precision polar mount that I am going to use with an adapter plate to interface the 4 bolts from the channel master dish with the three bolt holes on the Precision polar mount.

You abandonet, but I still have similar idea floating somewhere around Of course, before putting such a weight on Jaeger 1224, the last one should be properly reinforced.

thanks for sharing that rima. i hope nobody was hurt by the flying debris.
do you know what size the dish was that caused such catastrophic failure?

 

[RimaNTSS]

That was CM1.8
