Just rolled my own capacitor

Can you make your own transistor CJ?

So do you measure the tolerance as a percentage of capacitance or in thickness?

I don't think tolerance is something that is measured as a property of the cap. I think what happens is that the manufacturer cranks out 100k caps and shoots for a target of, say, 100n. Then they measure them, and the ones that fall close to the target are labelled 5%, the ones that fall further out are labelled 10%, etc.

I didn't have a target capacitance, so tolerance doesn't really apply.

I don't think it would be all that practical (even less so than these silly things I'm making).

Yep, the time honored practice of "binning."

I was just joking about tolerance.  Obviously it doesn't really apply to homemade caps.

I double dare you!!

You crazy son of a gun!

Do a true DIY Fuzz Face CJ, I dare you...

That is way cool!!

How did you figure it out?

I saw a youtube video where somebody shows how to make one with plastic food wrap and aluminum foil. I figured packing tape would be sturdier and easier to work with.

Missed this because of being on holiday, cool as h#ll! 

That is cool. I made a capacitor out of a plastic bucket, 600mL glass bottles, salt water, and oil, once, but nothing as flash as that!

I dare you to use this in a pedal!
