Due to all the troubles it may be easier to have a Downstairs Bedroom and have an upstairs Lounge !!!
Can't get couch up there.
That looks very straight and neat.
What is that in one side of the headboard - just a strengthening piece?
They tend to wander if they on the pendulum setting, but if you don't mind it being a slow (and ponderous) cut then the non pendulum setting tends to cut straight.
Fashion a block "peg" for the hollow section join, and just screw a sturdy board into the rebate of the L shaped section.
I did not want to take a chance as my blades are old but thanks for the tip.
ok a cut in a different plain to what i thought
and cut looks excellent but will always show unless you can find something to detract the eye or fully cover the join
Thanks for the advice its a good idea but the strengthener is right at the edge of the cut in the other half.
