Good evening all,
I was installing some “dado trunking” in an office recently and came across the dreaded ” not a 90 degree bend” scenario. You know how it works, they pre make 90 degree internal, external and flat bends but alas not say 135 degree ones! After I fitted the trunking, I set about trying to piece up the lid and that was when the fun started! Basically, it looked appalling!
So, it was time to think about it and then I had that eureka moment…..Here is how I did it.

I used a bit of geometry and eventually ended up here
At the end, the marking up ended up like this.

The next thing was to set up the lazer on steps and line it up with the centre line of the angle made by the walls.

Here, you can see it on the task in hand! Next job is to go to the trunking and fit the lid on one side overhanging the proposed join.

All I have to do now is get a pencil and mark the lid to do the cut spot on.
Lastly, I fit the top lid on the other side and repeat.
Finally, I need to deal with the centre lid by cutting out the ribs, so it folds.

Finally, finally, I simply fitted all the lids and ended up with this…..

And so, there it is.It just goes to show what you can do with a lazer, hacksaw, steps and a pencil!
Bye for now…..
