How to build a Kitchen Island Bench
Two different stock sizes are used in this project, they are 4x4 (100mm x 100mm) for the legs, and 1x4 (25mm x 100mm) for everything except the legs.
Wood type and look
I wanted a rustic look - more or less.
Sawn (rough) pine seemed the affordable option albeit a bit too rough for my liking. Dressed or dimensioned pine would have been a bit too smooth.
I decided to run with sawn pine and give it a slight plane and sand myself, making the finished product somewhere between rough and smooth.
I fixed all the pieces with screws and glue.
I used wood screws 1-3/4" (45mm) long where boards on their flat, were fixed to other boards on their flat, e.g. a tabletop board fixed to an under-rail.
I used 2-1/2" wood screws where boards were fixed to thicker members, e.g. a side-rail to a leg. I pre-drilled all the holes in the face pieces first.
12 ft (3600mm) of 4x4 (100mm x 100mm) stock. Allowing for a little bit of waste. Cut the four legs out of this.
56 ft (17m) of 1x4 (25mm x 100mm) stock. Allowing for a bit of waste. Cut everything except the legs out of this.
When purchasing lumber try to get the longest lengths as possible and when cutting, always cut the longest pieces first to minimize waste.
