As someone just starting out with woodworking as a retirement hobby, my project is a cheap wide clamp to hold long and/or wide boards. The sash clamp goes through the bench’s aprons, which are stabilised with a rail between the aprons and just above the sash.
(I realise of course that this might not be the best idea for promoting the sale of Axminster’s clamps!)o
If the competition is held again next year, I might be able to enter a project really worth showing off.
