Bending timber

[joeandrews]

I would like to run some pressure treated timber (15mm x 150mm) across my garden to contain gravel. I will need to bend it slightly as the path will be curved.

Can anyone tell me how to bend the timber, It will bend a certain amount but not quite enough.

Any help appreciated.

You would normally steam it, but if just for garden you could pour boiling water along it and pin it tight to the path with timber wedges until it settles to the curves.
If it's a steady curve you can support the timber either end and weight the middle to force the bend.Leave it like this for a few days.

You would kerf (aka notch or groove) the back of the timber, soak it and then it will bend

Use a router or just a saw for the kerf cuts
