We are heading home later this year, enough is enough, (but thats another story
)
So aiming for Alford
to be our base for the foreseeable
Once the shipping catches us up i'll have all my gear back with us if you need to borrow things like rod turners etc
As for your question.
I clamp the cork rings onto a threaded bar using a wing nut and washer at either end, the bar is a similar diameter to the original hole in the rings, i can measure it later for you
, then once the glues dries, i turn it with an electric drill to the required shape. once finished i take it off and ream it to the correct size, a bit like making my own preformed handles, but it makes things easier sort if you muck a bit up.
