Channel drain corners

[mcourtman]

Hi,

I've decided to put a channel drain around my conservatory at home because the water tends to gather. I have dug a trench and have purchased 20m of Clark Polymer Concrete Channel Drain (12cm wide, 9cm deep, 1m length).

I am struggling to work out how to mitre the corners as the conservatory is a 'half-hexagon' shape (Is has two straight sides coming away from the house, then two angled sides and finally a straight front).

Can anyone give me any tips on how to mark the joints at the corners? I've read you have to do a cut on both ends but could do with some advice.

Many thanks,

Matt

its just a straightforward mitre
you measure and cut the inner side to the point of your squint brick (assuming you have squints) and using a bevel come away at 135 degrees
then do the same for the one abutting it
can take a couple of goes to get right
