Cheap balsa wood and PVA do not work well together
Posted: March 10, 2014 Filed under: MIscellaneous musings, Modelling
Today I tried to build another prototype L-shaped built-up area model. As planned I used PVA glue in place of the superglue I had previously used … and found that PVA glue does not work well with the cheap balsa wood that I was trying to use. Almost as soon as the glue came into contact with the thin balsa wood I was using for the ‘skin’ of the model buildings, the wood began to curl and I had to clamp the pieces together with bulldog clips … which then made some unsightly indents into the balsa wood. (Cheap balsa wood tends to be soft and lighter in colour than the better quality stuff.)
I am therefore left with a dilemma; either to continue to use superglue – and have concerns about the strength of the glued joints – or to persevere with the PVA glue … and buy better quality balsa wood or find a suitable replacement such as thin bass wood or plywood.
At the moment I am giving serious thought to pursuing the latter course of action as I think that the resulting models will be of better quality.
