Fibo Gregorian - alternative motor setups

[Snuffer]

I see on the 120 Cm all that jeager stuff on your picture's
I have on my 120Cm the old orginal system can i have problems with that???

My 90 Cm are running o.k. with orginal system so i hope the 120 also.

John, can you take a picture from the front of the Fibo 120, i can see it slightly in the background but it looks damn nice in that color the little i can see....

I have used scotchbrite on the front face to take the shine off, more a matt finish like the bricks. I found the colour matching a bit tricky, as the texture changes the look of it, also the ambient light changes the appearance.
I have just taken this pic. 20:15 approx. and the bricks look much redder than they are. In the middle of the day the match is much better.

I also ran my 120cm with the original mount without any problems, and I quite liked the setup. I only changed because I was offered a faulty 1224 EL motor very cheap, and couldn't resist the opportunity to play.

Johns Fibo reminds me of the large Andrew dishes at the back with large holes around the backside of the rim.

My friend in Austria got a nice Fibo 120 with a Jaeger 1224 and the original backplate, see below.

Original back plate???

Actually the picture is a bit dark to see how the 1224 adapter plate is connected to the FIBO

Anyone know where can I buy the original back plate for the Fibo 120cm which works with the Jaeger 1224??

That will save me the trouble and time getting another mount modified for the same purpose of fitting the 1224 to the Fibo 120cm...

The satellite super store used to make them, but not any more, just as well as you pay through the nose with them

Have a go your self, it looks easy.

Here is another 1.2m Fibo on a Channel master polar mount. I quite like this idea. Cheaper way of motorizing than the 1224. It also has incline orbit tracking

It was a member from satdudez that sent me these pics. Hope he does not mind me showing them here

No problem Crossbones! The dish has now been replaced with a Precision 1.8 with a C/Ku LNB setup

 

[CROSSBONES]

No problem Crossbones!

Ok thanks mate. Hope you did not sell the 1.2m Fibo:-Nooo

No mate..carefully stored in the garage!

 

[CROSSBONES]

Thats the way mate, dont part with it.

I nearly sold mine, but glad ive kept it.

I also have a 90cm, and a 55cm fibo on the way:-worship

Get some pics up of it, would be nice to see it.;)

Here are some pics of my modified Fibo mount

I didn't attach the motor to the dish, only on the center spindle, as I don't think its needed.;)

A big Thank you to johnsattuk:-worship for the help and e-mails, and my good mate in work who did the work;)

Please let me know what you think johnsattuk

Nicely modded

I would be worried about a 90cm dish being restrained only by a 5mm roll pin in a 14mm shaft, I added two 5mm bolts to my 55cm.

But if it works then it's OK. One of my worries would be that if the pin sheared, the dish would fly round and aquire a big dinge when it hits the mount. !

Yes I did think about that, but the shaft is bolted to the motor adapter, in my 1st pic. It shouldn't come free! (I hope) lol

My concern would be the connection of the shaft to the dish plate, 5mm pin in a 14 mm shaft, not the motor to the shaft. I agree that the motor to the shaft joint is quite robust, 8mm bolt through 20mm shaft.

 

[CROSSBONES]

Hmmm......you do have a point there, maybe I will add the extra 5mm bolts before I field test it;)

Thanks for the advise mate;)

Uploaded some of the 1.8 in the 'pictures of members dishes section'...hope you like.

To take away that problem for 5 mm make a hole in the 14 mm shaft at top and bottom make i 8mm wire insite an use 2 - 8x 10 mm with a nyloc ring below insite.
now the shaft can never away from it house.

Good modification and simpel to.

Are suggesting to drill an 8mm cross hole through a 14mm shaft.

Simple - yes, Good - not so sure

I think it would weaken the shaft so much that it would be likely to shear off. It is not a mod. that I would use myself.

 

[Snuffer]

Yes but no more than 10 mm insite only for a screw 8x 10 mm op topand bottom

I have made two brackets out of box section for my Jaeger 1224 H-H motor.

Welded some threaded bar on to attach the C/master adaptor plate.

Here are the pics
