[benben5555]

Which of these details do you think is best? The labour and material cost is not significantly different so it really comes down to what will work best.

 

1. 215mm blocks in outside leaf, 140mm blocks in inside leaf

 

2. 100mm blocks all round

The 215 x140 would be quicker 

[Canski]

Outer 215 and inner 100 mm would be quickest. Blocks on their belly on the outer and upright on the inner.
