[QUOTE="Rick, post: 925500, member: 17143"] I had this problem for years when making speaker cabinets. you get it perfect finish only to your dismay to see the next day the joint. The expansion of the one panel against the expansion of say a 16mm thick piece don't match it changes with temperature and humidity. I am referring to butt joints. I solved this with 45 degree cuts and a pneumatic nail gun, but makes things awkward and a lot more complex to cut and assemble. I even tried 1mm thick polyester spray-on filler and the joint still shows with temperature and humidity changes. A neat trick you can use is machine it with a router and inlay solid wood the thickness of the butt joint. Done right it can look good. Last option is veneer it and spray the veneer to a gloss or whatever finish you like. [/QUOTE]
