I had always wanted to build a grandfather clock case and was given the incentive when a client gave me the a modern clock mechanism and a photocopy of a reproduction of an English Tall Case clock to follow. I had to increase the plan dimensions to fit the mechanism, ash wood was chosen and I ended up with 23 metres of approximately 200 x 25mm rough-sawn at an average length of 2.4 metres costing just under $300.
This is not the ideal style of clock case for anything other than an antique clock mechanism. In modern clock mechanisms, the pendulum swing (which should always be tested) needs a straight-waisted trunk style of clock. However, this project has been done to the requirements.
