Starting to cut out timer parts

Before cutting out the timer parts, I drilled whatever holes were needed.  Since I don't have a drill press, having the parts all on one piece made it a bit easier.

Then, I roughly cut apart the pieces.

After about two hours of work, several of the parts are now cut out.

Timer part patterns glued

I printed, cut, and glued the patterns for the 1/2" thick parts for the timer...

Next clock: a minute timer with gravity escapement

After months of equivocating and then bursts of design activity, I have a design for the next clock I'm planning to build.  I often find the need for timing short events, a minute or so, so a timer seems like a practical project.

The design has a double three-legged gravity escapement, mostly because that looks visually appealing.  Not desiring it to take up much wall space -- so this means fewer wheels -- I've decided that this clock will only have a seconds hand.  The clock has a ratchet wheel to handle winding, which will be by a pull chain.  At this point, I think the drive chain should actually be a flat ribbon, but we'll see how that goes.
