Chair bevel cut.

[Lbob131]

Any tips  on how to bevel  the corners  accurately  and join the back rail  to the side  arm rests on a  chair    similar to this.....

The  chair back  rail  will  have a curve  and be made  from laminates glued up.

I'm thinking  bevel  both  sides  of  the  back piece first as though  it were a straight section.
Then make  the cuts  on the sides.
Can afford to lose a little  material  on the sides if I get  the cut wrong I'm thinking.

Or  make the bevel  cut  on the sides  first?
Slightly concerned  I'm gonna get this wrong.

Maybe I should  just laminate some mdf  up    for the back  and  make the cuts  on that first?

Wow this looks good! I like design. Did you use dominos for the joints?

Yes dominoes.

Too late, sorry, but here's a tip for finessing the bevel:

Cut the piece a hair long.  Snugly, but not tightly, clamp up with a strip of sandpaper on each side between the bevel and the leg, and a little longer than the crest rail is wide.  Holding the rail with one hand, gently pull the sandpaper out.  Repeat if needed.  I've found this to dial in a very nice fit.

Thanks. Thats a good tip.
The back piece  is slightly narrower  than the sides  so I was able  to creep up on the  cuts to make a  good fit.

Yes  that's JB's  visionary work.  Suffice to say  I had to do all  the  design  work  on  my  cad  program.  A number of  basic  chair/stool design  concepts  are incorporated  which I had to study and learn  before I started the project.
And not least the Danish weaving.
Its a gift  for a  couple who are getting married  so I made no  profit  from the  one off piece.
And they are delighted..
Had the time  to do this recently after being laid up  with a broken  leg  after a roof fall  and managed the build whilst partially  immobile on one leg  and crutches.
Was a  great inspiration to get me  up and moving.
The  domino 700  makes  the joinery task  very easy  and efficient.
All credit to JB though. Its a wonderful  design  to take from  an image.  So  simple and elegant  and then  tweak  it on cad  and then  paper  and on  to rough sawn lumber  and finally  the  finished piece. And a few joint testing samples also.
I found joining the curved back  to the sides  the most challenging part of the build. The finish is two coats  of morrels  40% sheen  two pack  catalizying lacquer.
