Many thanks for the hint - with my standard water based wood glue (Ponal-Express) water is doing the job very well. But I will try your way - steeling, better borrowing my wife´s fluids.....GREAT and BEAUTIFUL work UWE, hate to give advice to such a master builder such as YOU, because i have been a a RE=DO expert in taking things apart my procedure works well on both PVA and CA what i do is using NAIL POLISH REMOVER it has bto be 100% acotone i swab the joints with a cotton swab and then take i9t apart using an exato blade sometimes you have to do it a couple of times can not rush comes apart and with no damage or discoloring. JUST MY WAY Don
