Once again I am doing old work, this time on a 'plank' house. The exterior walls are made up upright planks, 3" thick , some up to 20" widebark included..
There is simply clapboard on the exterior, plaster/lath on the interior. I could just about sign my name with a sawzall by now,,,
The interior walls are mostly the same plank design, the exception being they are thinner, approx 1-1/2", maybe 2".
This allows for 1-1/2" dp 4 or 4 11/16 sq. with a mud plate. So comes the Q....how to maintain proper burial depth of wires???
Anyone else been there???
