Hi folks,
thanks! Womble, yes, I guess at some stage in their life, there might have been plastics at the end (it's open tubing now). Was sondering if I could just stick some narrower tubes in there without making them too heavy. Would a blacksmith have that kind of thing?
And if weight was an issue, I do like valmet's idea - electric fence posts might indeed do the trick. Maybe with some tape to make it more visual....
Cheers!
