I seem to be making things in fours so I thought it would be good to make four presses. They are from some 'found' wood and a packet of bolts from Wilko's. Worked out at £1 each - can't be bad. About 300mm x 190mm they will take up to A5 so I have enough to keep things pressed.
The other thing I have done today is cut all the boards chamfer them and laminate them with some thin card stock.
