Hi Richard. I recently used black tissue paper that you can easily find on Amazon. Here is my methodology: I wiped a thin layer of wood glue on one of the joining surfaces - laid a piece of the tissue paper on that surface and gently smoothed it down with an old credit card with a smoothed off edge - let that dry. Next I wiped a thin layer of wood glue on the other joining surface and firmly clamped the parts together - and allowed that to dry. I found that the tissue paper did weaken the joint but not enough to matter. Do a trial using this approach and see if that would work for you. I’m not the only one to represent tar soaked flannel in this way. The only downside is it surely makes a mess.I have looked everywhere for this
Are you in UK If so can you send me some!
Where did you get it Or what is it actually called
Is it on Amazon where you are
Very frustrated THANKS

Sorry to hijack your excellent build report, Alex.
