Benjamin Franklin Clock

thingiverse

<b>About 260 years ago, Benjamin Franklin designed a clock with one hand that told both the hours and minutes. You can read more about it here: https://founders.archives.gov/documents/Franklin/01-08-02-0060</b> Aside from the 3D printed parts you will need (approximate): 1 yard long by 1/4 inch wooden dowel 3mm stainless steel rods (search for 3mm RC rods) $2 in US pennies for the drive weight 1.5 yards of mason line a paperclip or something else for the drive weight hook <b>I was inspired to create the clock after finding that the clock faces had been modeled. Here's the summary from jamcultur from his "Benjamin Franklin clock dial":</b> "Franklin's design never caught on, but clocks based on it have been produced in limited quantities from time to time, for example, an electric version by Paragon in the 1960s, a weight-driven version by Thwaites and Reed in the 1970s, and a wrist watch by Meistersinger in 2015. For more information, see http://www.ablogtowatch.com/meistersinger-benjamin-franklin-watch/ My 3D printed version of the Franklin clock dial is very similar to other versions, except that I replaced the Roman numerals with conventional numerals. I designed it with raised lines and numerals so that I could color them with a sharpie after printing. The small dial is for the seconds hand." <b>In addition to using the clock faces from another project, I also used the escapement and pallet from A26's "Clock"</b>
