Hello,
Second hand, these are not costly tools nor hard to find, I got the one I use from that guy not far out of Cambridge, can't remember exactly where, the shop called Old Tools or something. But there is no substitute for a good fro.
I don't lock anything in position Mak it's all just a matter of eyeing. That video, I must admit is a bit painful for me to watch. It was the first time I had used that tool, the first time I'd ever seen one actually. Once I had tracked down some history about it, things went much better. Now I really like it though would even better were it suited to my left hand inclinations.
I'm sorry I had forgotten to answer your question about the cranes Mak, but if you meant storks, we had a good year this year almost 100% nesting pole occupancy in my observations. Other than that, geese have been coming down now out from Lapland in forceful numbers this past week to settle on the pasture lands for winter.
Greetings,
Don Wagstaff
