I'm going to do the same thing. I have first crack at a 1.8M Prodelin that was on a now defunct car dealership...I just have to get it off the roof...
I whish I had a 1.8 or 2-meter when I built my H to H mount for a 1.2 meter, AC you're 1 luckey guy.
Hi Brotherhood, yes it can be done, did 1 here with a 1.2-meter CM dish, an what Turbo told you is right on track to tune the dish for the arc. also a little playing with the offset angle an the elevation of the c-band mount you can get it to track perfect.
Now this is what I did here. had a Horizon to horizon mount from a 12-foot CFI mesh dish, then cut the azmith bar to acept 2-1 1/2" box tube stainless bars, bottom bar for the offset dish will be its pivot point, for it elevation of the offset angle. top bar or you're high side of you're azmith bar, cut both ends on a 45 an drilled a 5/8 hole in them to have 2-5/8" treaded rods going tru them for the adjustment of the offset angle of the dish. now when doing all this remember metal moves with heat an the 2-bars need to be in line with each other an level with the top of the azmith bar, i just tacked welded all to my table, then when all the welding was done cut the tacks louse. now the mount was done, an then built 2 bars to bolt to the dish, I used 1 1/2" stainless angle drilled it to acept the bolt holes of the reflector an welded 4-taps on the other cornersof the 2-angle iron, now the bottom 1 1/2" angle (pivot point) have a 1/2" bolt going tru it, an on the top 1 1/2" angle bar had to make the hole e-long gated, because as you raise the elevation of the dish on the mount it came into a bind with the 5/8 threaded rods. now at the end of the treadeded rods ( 2 of them) I tig welded 1" long 1/2" sec#20 ID tubing on to the ended of the 5/8" treaded rods, so had a 1/2" bolt going tru it that bolted to the top 1 1/2" angle on the dish. an when I 1st put it all together an ran it, an it tracked reall good on the arc, an boy was I surprised, but after playing with both the offset adjustment an the elevation of the H to H mount was able to get it perfect.
I just whish had a digtal camera so can post picture's of the mount would make things alot easyer, but don't even know how to upload a picture, so thats another learning curve.
now I bet I got about 40 hours in cutting, weding an figuring it out, an unless you can weld an work metal, or have a deep pocket to pay a welder to this may not be worth it. an the hole mount that I built was all out of stainless steel. but I am very happy with that set up. the problem that I have now with it is the return count from the read switch, running a magnet wheel from the worm gear (almost like the birdview set up), now working on a small transmission to come off the worm to step up the counts. It orginaly had a 10K pot that was used on that mount so just about all has been hand made.
Now the hole secret to get it to work is making the offset angle of a polar, or H to H mount to have a real fine adjustment that adapts it to the offset reflector, because all those mounts are for a prime focas reflectors with a 2 to 8 degree (that was cut off an dicarded) offset, most of you're offset dishes start at 22 an may go to 27 degrees of offset angle of the lnb. an when you start peakin it in, just treat it like you will set up a c-band nothing different. when I 1st started this thought it was going to hard but all in all was not bad to get it up an running, was a lot easyer in the tracking than i thought.
Good luck on you're project hope it all come out great.
