Hi John,

I use Gorilla woodworking glue for most planking balsa & hardwoods.

Regards Ray

I use mainly aliphatic too because it is relatively cheap, easy to apply, grabs quickly and sands quite well.

I also use cyano where I need to tack something in place very quickly and there is some strain on the plank. I then run some thinned aliphatic into the joint by capillary action using the sharp point of a wooden or bamboo kebab stick. You can buy this as superphatic by I choose to make my own as I can then vary the consistency.

The problem can arise with water based glues on surfaces that are going to be varnished rather than painted. I have a project coming up that will be planked in Mahogany and then varnished and I will probably use a clear epoxy finishing resin. If this soaks through or into the wood it ends up being the same colour as the varnish whereas other glues can cause light patches. Cyano does not affect the colour either so sometimes used in combination.
If you use water based glues be very careful to lightly sponge away all excess glue but this can be quite difficult.

I have never used Gorilla glue but Ray can tell you his experiences on that. I have never seen it here in Spain and don't know what it would be called. If I do find some I might give it a go and I understand it has some gap-filling properties.

My missus make her toasted sandwiches using Havarti light cheese. This is probably the best glue know to man given the trouble I have getting it off the sandwich maker. I don't know how it sand or varnishes though
