I'm having problems working out an angle
its a 6 sided box i'm reasonably sure the mitre for the sides needs to be 30deg but for the roof
i get a nice peak on it if i use 50deg for the point on the triangle but i cant for the life of me work out what
mitre i need to make the joins on the roof neat.
can anyone tell me either how to work it out or what the answer is :) please

'GRIPFILL' ;) (google it)
nooo, i need to do it right

is it the angle of the triangular pieces that make up the roof? That wiould depend on the slope of the roof

yeah thats my problem, do you know how i would work it out?
50deg for the 6 pieces gives me a 30 deg gap from the floor
is that any help?

couldn't you built a model out of card and keep cutting the triangles until you get something that looks right? Another time i'd try and work it out, but i'm struggling with an headache. a Netto wine headache ???
ok, i hope your head gets better soon
lbb
getting better.
how's your Trigonometry? :D
trig is that sine cos and tan type stuff?
i have a table for them from school, smp its ancient but i guess they are still the same:)
so if they are the right thing i can do that.

Is it a box or feeder you are making?
I found a picture of 6 sided feeder, is this what you are making?

i can't help with the angles, just being nosey ;D

sorry lbb - i thought you wanted to know the angle of slope of the roof for a given angle of the roof pieces. You want to know what angle to cut the roof pieces so they fit together exactly
I *think* it's the same angle as the slope of the roof, if that makes sense. I'll try and find some triangles and have a play :D
Is this any good?

I have a bird box that a client of mine gave me as a ty present... But I don't have a tree! Swap you for some Dora the really annoying explorer stuff?!?!

awww ollie thats sweet
thank you for the offer,
dora is yours anyway, and your very welcome to her

so, have you solved it yet?
done it, but it's complicated, and it's not the angle of slope, neither. If I were you i'd guess and make up the difference with a filler :D
Have made loads of 'em.
The usual angle joining pieces to create a roof is the same as used to create a corner, that is; 90dg. To get that you need to make the angle 45 on each piece.
If that's too complicated, do a butt joint, one piece butted under the other. Just make sure the top piece is longer by the thickness of the board than the under one.
Clear....... ???
PS: Do a search. I put pic's on here a coulpe of years back.

no, it's an hexagonal roof, meeting at a point.
Can't say what the mitre angle is without knowing the dimensions of the triangular pieces. It changes
