about the wobbly sync-line:
1. your DVD-drum should run smoothly, without radial movements. If you touch the drum gently with your finger while it is running, you should hardly feel it bumping against your finger. So no wobbling of the drum is allowed. Wobbling will introduce wobbly horizontal lines.
2. The distance of the slits on the drum should have equal distances. That is difficult as they should carefully allign a certain number of slits around the drum. Also unequal slit distances around the drum will introduce wobbly horizontal lines as well.
Hi Klaas
Yes lining up the drum 100% in Balance is a problem i suppose is harder than trying on disc ,as well its only held on one side which doesn't help on a plastic or any sort of drum but do the best you can with what you have got ..and live and learn ! I have learned that the base of the drum needs to be pretty strong to stop wobble .
I have not tackled the small drum yet as theres a slight wobble there since it was home made which might be causing wobble to as well.
So i have a few more things i want to try like that and controlling the small drum from the large .
I think i did better on the wobble problem on the last drum direct drive ,but the pulley system did let me show i could run the drum to view 48 and 60 line ....the last poorly but got there .
The advice is noted Klaas if i do a 3rd drum monitor i will be trying with my poor construction skills do better i will get it right in time ... as always you would always do if different if you did it again
