Dial making Pt.10 / Jumping hour module 3

Infixing the bushes to the dial plate. I drilled the holes in slightly small sizes. Adjusted with hand reamer.

All bushes were installed. Simple and light work.

Actually, I decided to change the hand winding movement from ETA2801 to Fontainemelon (FHF) 98.

<FHF98 spec>
Frequency : 21,600 A/h

Power reserve : 39h(?)

Jewels : 17
Diameter : 11 1/2 ligne (25.60mm)
Total height : 3.60mm
Mounting hight : 1.30mm
Stem hight : 1.90mm
Hand dimensions : 130/90/21 (hour/minute/seconds)

Comparison~~~

<ETA2801 spec>

Frequency : 28,800 A/h

Power reserve : 42h

Jewels : 17
Diameter : 11 1/2 ligne (25.60mm)
Total height : 3.35mm
Mounting hight : 1.80mm
Stem hight : 1.80mm
Hand dimensions : 150/90/25 (hour/minute/seconds)

ETA movements are too expensive for its appearances and function, I think. I like FHF's old fashioned looking and reasonable price, of course. There is no fear of lift-up of cannon pinion unlike ETA. Additionally it seems to be easy to be decorate. Because both diameter is the same, it is easy to change the plan.

The cannon-pinion was press-fitted with the handmade pushing parts. This parts will push and turn brass-made star wheel once an hour.

Steel-made star wheel and brass one were united by being shifted by 10 degrees.

A gap of 0.15mm are made between them. It is because of avoiding the interference of the brass wheel and spring lever.

Temporary assembled.  I checked that there are no problems with its motion.
