Thinner plywood for the end frame?

    Hi everyone,

    I am wondering about the acceptable thickness of the plywood of the end frame (Paul recommends 1/2″). My only plough plane is a record 43, which widest blade is 1/4″.
    Is it possible to use 1/4″ plywood for the end frame or it would be too fragile?

    Otherwise:
    – is it possible to make a wider groove with 2 passes of the plough plane?
    – would 1/4″ plywood be enough if I divide the panel in 2 with a vertical rail to increase the rigidity?

    Thanks in advance for any help!

    Rascar,

    I am in a similar situation. My two plow plane blades are too wide and too narrow. I plan to use 1/2 inch plywood and my narrow blade.

    I will make a groove along the center line and then work from the center gradually closer to each edge.

    Good luck.

    you’d have to use a record no44 or similar, you could actually do two grooves with a no43 as long as the end result fits, also you’ll find the ply is 12mm not 1/2″ so there might be a gap anyway if you used an imperial 1/2″ cutter, cutting two grooves instead could make a tighter/better fit. I have not made the project but it’s on the ‘to-do’ list.
