PF-120 / PF-106 foundation
Received my order of PF120's (Mann Lake) today. Having used the Dadant plastic 4.9 in trials and it not working so well, I can see why this design works so well for many. Don't like plastic frames, so I'm cutting off all the frames and putting the foundation into my wooden frames. Works just fine.
Used a piece of 3/4" plywood to set the frame on and run through the table saw leaving the bottom bar attached.
Fits nicely into a wooden frame.
