i dont see how that clamp system stops it from going left or right, its downforce on the clamp, yes, but cant see how it would stop it going left or right gradually with wind force.

it would make more sense to drill through the two motor brackets and pole and putting a threaded rod through with nuts both sides, done up tight.

drilling thru a scaffold pole, might be challenging though :)

Well, when I last used the Gibby a few days ago, it hadn't moved laterally since @Channel Hopper set the dish up in June 2019 - OTOH, I haven't checked again today.

i managed to move dish back into position, i will put a bolt or rod through pole and lower motor mount bracket over the weekend. that will stop it moving. might move the pole though, but doubt it. could do the same with pole and t&k actually

i do wonder at what point should you stop re-enforcing - i.e if i put a bolt through to stop the pole moving, and then i put a bolt through the motor clamp and pole, this means nothing can move, except possibly the dish on the motor mount, but the motor mount metal is soft, and the teeth of dish mount, bite nicely, so what is left, other than dish resistance against the wind - is that where you need to be ultimately, dish v wind ?

A little less analogue, and a lot more crap.

The mast could spin round on the clamp, tripod, or whatever it is locked into within a buried ground system.

Then there is always the chance of breaking the gearbox if it is the weakest piece of the chain.

Sometimes a bit of give is better than having everything locked up solid, and realign when things go out of kilter.

yeah, thats what i was thinking
im in two minds whether to stiffen it up, or to leave it, its only 10 mins for me to go back up ladder and re-align

Well, I have just checked the Gibby on the Dark Motor on the 2" scaffolding pole on one of the weaker channels on Thor - and, if there was any "movement" then it was almost undectable - maybe 0.1 degrees - , but that could simply be a very slight backlash problem. Mind you, that dish is mounted about 3m off the ground in a very sheltered spot, so it's rarely (as yet!) affected by wind issues.

BTW: If anyone has tracked down the thread with those mods to the Dark Motor mounting clamps, then please post a link here as I do still have the pics but not the text which outlined what I bought, how I modded that and how I then installed the modded bits.

Just had the first flurry outside, one might say a sleeting amount.

Much to our surprise, there was a flurry of snow here just after breakfast. All gone now with bright sunshine now ascendant.

Snow at Easter. This reminds me of a time in my teens when I went with a friend and his parents to Lake Bala to go sailing. We stayed in a caravan and then it snowed on Easter Sunday. Delightful!

1.2Mtr Polar MTG yes it has been on the arc for 35 years and is now fixed on 13 East using two pairs of rusty molegrips. Unlike me they never groan but always perform.
