Thank you for your help Zane
. It sounds that the hack saw may well be safer than trying to work on the glue problem. I had thought of inducing something but had not considered the possible damage you suggest...shudder
. I think I will try and do some fotos with a jury rig to place a camera which at least will tell me if there is any improvement or reveal they have a problem if used for photography.
It really boils down that I cant help myself when it comes to making things
at my age I should move on and just buy one (a Williams) they are only the price of going without a case of beer a week for a year and I dont drink so I can justify it I suppose
.
Thanks again.
