Bending teak decking

[bromleybysea]

I am replacing a couple of short lengths of decking. The planks are about 10mm. thick, 60mm wide and up to 650mm long. They will be bonded down onto the GRP sub-deck. I need to introduce a slight curve to the planks- about 8mm deflection in the middle. I can knock up a steam chamber but before I go out and acquire a bit of plastic down pipe for the purpose, is there an alternative tequnique I could use? Thanks.

cut over wide planks to the req shape is the only way

Teak does not steem well, I've never had any joy trying it.
Bending it cold is the normal way, but getting 8mm deflection in such a short length will be very difficult.
Planing a curve from a 68mm wide stock will be much easier.

He will have a big problem trying to plane the plank accurately in the curved shape. Its much easier to run the teak through a machine in a straight line so that its rabbit and width are precisely calibrated.

8mm over 650 mm is not much deflection. He should be able to manage that cold. Holding it down while the glue dries is the problem. When I've done the job in the past, I've used penny washers under screws in the seams so that the screw holes get sealed over when you pay the seam with caulking compound. Otherwise you need some HEAVY weights.

I have steamed teak curved ( S shaped ) & laminated bulkhd trims
