Hi all.
I plan to build a shed door from 28mm thick oak timber (varying widths
94mm - 120mm).

Questions :

Should I biscuit and ledger them together?

or

Just ledger?


I figure on fitting a 5 lever mortice with padlock but I would need to
reinforce back and front with steel.
Do you know where I could source 2 pieces of 1/4" plate about 6 - 8" square?

Thanks.

Arthur
