Shirley, reading through the threads with videos would give you some ideas?
... told you before-don't call me Shirley
Right then, to get started we need a little bit more info from your end MrDish1 to enable more accurate feedback advice
What style, O/S or PF, and size of dish were you thinking of putting a rotating lnb onto.
For which reception band, ie: Ka, Ku, Cband or other.
For home brew polorisers / skew devices etc to perform to acceptable levels require the use of some fabrication skills and a suitable work place and equipment to enable a quality finished home brew product - sometimes it can take many attempts to make something, usually the same object, before you get it right so patience is a virtue.
Source of cogs etc can be a pain to get sometimes, 95% of my stuff i use comes from China.
If you can post decent resolution pictures of your dish or any motorised skew devices you have been looking at and want to replicate will help a great deal.
Good luck with it all - go for it
