So you forgot to cut sand retention grooves in your flask...

    Here was my quick and dirty solution. I was too lazy to unscrew the boards and run them through the saw or to fire up the router. Seems easy enough and a good way to burn off self-reproach due to forgetting. :) Would have used a framing hammer with its cross-hatched face had it been at hand.

    It’ll hold the sand.

    Possibly more convenient than grooves because the sand will actually fall out when you want it to.

    We call that a “Birmingham Screwdriver”, that’s not to say that Brummies are a load of rough assed delinquents.:D

    a small forstner bit works well to make many circular rings Freemont flasks had a very similiar circle pattern inside (sorry cannot find an in image)

    a small route to cut groves works well ( I had to do that once

    In fiction, the foundry-person's mallet/hammer is called a yarrop. (An intercepted term, It's so old no one currently alive knows where it came from.)

    Hence, that's a full yarrop flask.

    The sound the guy using it made when he smashed his thumb with it....of course it was probably a stone tied to a stick.

    What sort of router bits are usual (for sand-retention grooves)? I got at least one core-box bit for this exact reason, but I'm a Nüb...

    Well...now I have a new shortcut. I bet it will work on aluminum and cast iron.

    Made me look it up.LOL Great story! Tricked his dad into killing Cain and then his dad accidentally killed him. Wonderful ending...blood thirsty killer who is killed by his victim's grief.
