Hi Mickky Wood is easily glued with a white aliphatic wood glue, epoxy resin or even superglue. Assuming your model is intended to be sailed then the glue needs to be waterproof. That said many modellers cover the outside (and sometimes the inside) of their hulls with glass cloth or fibre mat impregnated with resin. The end result is a very strong and waterproof hull. The glue used will be covered by the cloth/resin so need not be waterproof. Wood glues tend to be slower setting so you have more time to position the pieces, but then have to arrange a method to hold the pieces together until dry. All three glues will give a strong joint and the resin will also fill any small gaps. If this is your first foray into working with wood I suggest you visit your local pound shop and purchase a sample of each type of glue and practice with some scrap wood to see which you prefer. With any glue the surfaces need to be dry, close fitting and free of any contaminants. The oil off your fingers and hands can cause problems so avoid touching the joint surfaces after you have prepared them for glueing. Good luck wth the build dave
I used to use £1 shop twin epoxy until I installed a prop shaft with it in a fibre glass hull. I didn't paint it or anything. Found it softened and peeled off. So now avoid as not sure which £1 shop it came from. On this subject I'm struggling to find anything but Gorilla glue in the shops. Seems it's pushed Araldite, Evosick and even Wilko's own brand exopy off the shelves.
Just to add my pennyworth, I am building a similar model (sea rover) at the moment and am using aliphatic glue, it grabs after about 10 minutes, strong after 8 hrs, waterproof when dry and will take a stain if needed. Brilliant
