I have given thought to a new style of jig that is adjustable and uses a copy but .... to busy to develop that atm but time will tell.

I just fitted a mortise lock recently and did not have a trimmer with me. The plate on the edge of the door was mortised by hand. What a pain. The timber on the door had grain going in every direction .... and with a plate about 250mm long I sure with I had a trimmer on site.

Yes the timber used in door edgestrips is often rubbish plus you have the mdf skin to contend with that is not chisel friendly either
Do you use a corner chisel as well?

No I just use a 25mm chisel or wider, drop one edge down in the shoulder and then tap the other edge down into the corner. Do that in each direction and knock the small piece out.
