DIY Light Hat #2 – mark up

  1. Measure 160mm or 6.5 inches from the top of the bucket. And mark the measurement all around the bucket. You don’t need to be exact.

  2. Mark places where you will be making holes. The first is at the top, about half way between the attachment of the handles. Only mark the holes circled below. (The other holes you will need for the two wavelength version, but not the one wavelength version.)

3. Now mark holes lower down, on either side of the 160mm or 6.5 inch mark. You need to do these holes in two places, on opposite sides of the bucket. I do them under the handle attachments, as it helps keep me oriented.

  2. Internal diameter at the top around 260mm (~10.5 inches). Definitely no less than 240mm (~9.5 inches) and no more than 300mm (~12inches).
