Credit goes to Ana for her excellent table plan. Most of my timbers were I found free at the hardware store (Bunnings Warehouse in Melbourne, Australia). Tabletop I made from construction grade hardwood, jointed, glued and biscuit joined, planned, and sanded (40 to 600 grit).
Bunnings has a free timber section where they store all offcuts that are expensive to get rid off than given away for free. I had some 50 odds 70mm by 70mm rough timber pieces that they used for packaging pallets. I then run them through the jointer, thicknesser to bring them down to 65mm by 65mm.
Bunnings dropped the price of construction hardwood nearly half as much as due to defects they have. They were 90mm by 35mm, and 3.6meter long and they cut it half for free.
Tabletop is 1200mm by 900mm. The total height of the table is 750mm including castor wheels. I think I spend more bucks in electricity bills than materials mainly due to running all types of machines forever :) The Shellac is expensive in Australia as much as the hardware was when compared against USA price tag.
