This chair is more of a concept piece.
There are a two elements I wanted to explore in this design.
Ply’s direction – In all my previous works plies were in same direction through all the piece. In this chair, it was obvious that the leg and bucket must have vertical plies to achieve strength while the base has to be made of horizontal plies.
The challenge was to find a way to make this transition interesting and visually pleasing. The solution tested here is to glue the plywood strips of the leg in a spiral manner so there are 4 “faces” instead of usually 2. (Pic 4)
Springiness – I wanted to incorporate some sort of shock absorption to this chair. The shape designed has a flexibility and start to flex with weight of 40kg. To prevent a break from overweight at 100kg the sit layer will be stopped and supported by the bottom layer.
I’m still considering a trim of the sides (Pic 5)
Any C&C will be appreciated.
Cheers,
Dave

Very nice, Dave. I understand the first one to be the concept! You learn a lot by making at least one. That plywood shapes up quite nicely.
I wonder how the sides of the chair would look if it were not straight. Plywood looks interesting if there is a bit of curve to it . That shows some of the ends of the plys.
What kind of plywood is it? What thickness did you use?
Cheers, Jim

Jim, many thanks for your insights mate.
I usually use recycle plywood from shipping crates so lets say kind in unknown/recycled ;)
For this chair i had 15mm thick pieces.
I totally agree about the sides.
As it is a trial piece I may continue and do as you suggest or cut as per pic 5.
The idea to leave it straight ATM was to create some contrast to the leg which shows lots of plies running everywhere.

Well, this is quite smart concept and I bet it works good. Only, I would rather see some hardwood for leg set – but as you said it’s just a concept -well done!

Nice work Dave !!!
This is a very interesting design and I like your explanation on the reasons of grain direction and flex of the chair under weight .
I would like to see more of the construction process .

How did you attach the legs/bottom portion to the seat/top portion?
Have your say...
