Too true Peter.
If it works made from anything and everything don’t fix what isn’t broke.
Made many a jig and sled to help make My boxes Peter, finally set up with a ball bearing slider that I can alter to suit any pen, kit or design.
The pocket ones I make started off on the sled, however I am now trialling a CNC which seems to be doing OK but I need to get things dialled in before I’m confident in selling them made with that.
All good experience tho ,enjoying the ride.
