Likewise to far for me, (sorry just notice the date of the posting ) attended a Roly M. demo a few years ago Very entertaining and informative, shame I had just bought Hamlets hollowing tools- think Roly's hollower would have been a better buy albeit more expensive.
New workshop on its way going to be erected around my Lathe so no excuses going forward, also need to make the effort to rejoin the Norwich woodturners club and rekindle my interest.
