Another technique is to use a meta chassis l plate under the wooden top, for grounding and shielding, and for mechanical strength.
The combined weight of the transformer and chokes s could be a "challenge" to an un-reinforced wooden top.
Best to lay out and drill / punch the metal chassis plate first, then drill the wooden top to match it.
