Not being a master of the English language, or any language for that
matter, I do understand spiling. I do it and it's easy.

I'm having trouble using the correct form of the word.

The art of spiling, spiling being a verb.

Is spiled past tense and spile is the noun? To spile?

Are the following sentences correct?

Spile that plank for a good fit.

I spiled all of the planks for a good fit.

Yup, just a dumb ass here.
