Melamine and dowels

mardi 7 juillet 2015

Hi! My name is Koen, I´m a dutch guy living in Peru.

Some time ago I started building small decorative shelves.
Here is a link to one of them:

I´m using dowels and simple wood glue and the wood I use is melamine. I live in Cusco, a small city near Machu Picchu. There isn´t a lot available here, no Roo glue no Titebond. (there is polyurethane glue, but it can be a bit messy and difficult to clean) People use dowels as wall plugs. There isn´t really anybody here who works with dowels as in joinery.

I wanted to ask for some advice on some problems I´m having:

1. The melamine sometimes expands after the glue on the dowel on the bottom edge dries.(I don´t know if I´m saying this right but it´s not the surface but the side where you can see the woodchips) There are 8mm dowels and 5/16 dowels available, so I already switched to the 5/16 dowels and I´m using a 8mm drillbit. Fits perfectly, takes me a tiny little bit of strengt to push it in. But the melamine still expands, it goes from 18mm to 18.7 mm, leaving me with a ugly joint. The only option I have at the moment is to apply some glue the day before doweling so the wood is stronger. But that takes away strenght from the joint.

2. Glue in general, without Roo glue or Titebond, I don´t really know which glue is the best glue to use. I found a really strong contact adhesive, but it takes a lot of work to apply.

3. I want to start building some bigger things, like this: http://ift.tt/1NQcIZO. Can you do something like this with dowels? Will dowels be strong enough? If not, what other options do I have?

Thanks in advance!! Sorry if some things are not clear.
