So today i got on with laminating the cores together. It's a bit messy but feels like the project is moving forward so it's all good.
As I said yesterday, I used PVA glue instead of a more specific wood glue such as 'no more nails'. Although PVA is used as the friendly, child safe primary school glue, it's actually a bloody good wood glue which, when dry, can claim (much like no more nails) to form a bond stronger than the wood itself!
As I've found out, the benefit of no more nails is that it cures very fast. This is great for holding 2 pieces of wood together but for lamination it's not so ideal.
PVA takes about 24 hours to cure so it allows you a fair amount of cock up time.
For this step I used:
5x G-Clamps
5x 20mmx30mm ash (I cut them to the required length earlier)
A healthy amount of PVA glue.
I bought WAY too much glue but I'm sure that will get used in other projects. In reality a small 0.5L bottle will do a pair of skis with plenty left over.
I lined up the planks next to each other with the edges that needed glue facing up. This way I could pour out some glue and spread it over all of them in one go.
Apply more than you think you need.
Just be careful when you clamp them up that they don't slide around too much. A light tap at either end will even them up.
Another problem i encountered was that each plank twisted slightly as they were clamped. This would be solved with a brace running top and bottom which is clamped shut but I didn't have enough clamps for this!
WHen everything is clamped tight, excess glue should ooze out top and bottom. Leave them like this for 24 hours... have a cup of tea, watch The big bang theory and sleep!
