Just say it's for mental health to promote healing, with any luck by summer I'll have made the rest adapter for it although saying that I've got stuff from last summer I've still not done.
Really what I need to do is create a clamp on arm for the bench which can be easiley folded out the way if I have a bad spasm, probably will add provision for a pellet tin and beverage too.

I really need an actual workshop me thinks instead of an Ironing board and crate in a dining room.
