Cutting polistyrene cornecces

[garage nut]

Busy upgrading the outside room to a gym.

Even fitting cornesses and that is where the problems started. Tried cutting them free handed with a knife and that did not work.

Then out came the saw I used initially to fit skiting boards and that did not work.



Then I tried a hacksaw and the miter box, and that did not work either.

Then I simply ground away the hacksaw teeth and sharpened it like a knife.



Using the miter box I now produced repeatedly a clean and accurate cut.
