Help on Septimus Build - Minute Arbor
  • Hello,

    Any help would be appreciated.

    I don't see directions on page 17 (minute arbor) telling me to glue parts "Pinion (4B)" or "Spacer (8A)" or "Cog (9A)" together. I see them on the arbor in the pictures with the ring stops holding them together but i'm not sure if any of the above mentioned parts get glued together before i put them on the arbor.

    Thanks in advance!

  • They are all glued together.

  • I had to think about this one for a minute when I built mine. They are all glued together.

    The pinion drives the cog at all times. Independent of this, when you set the time by moving the hands, the arbor slips within the whole assembly.

    The instructions do say that the fit of the spacers on the arbor is tight, but I found it to be too tight. I had to ream out the hold very slightly with a round file. With the fit as tight as it was initially, the set screw on the minute hand would have slipped before pinion/spacer/gear assembly.
  • petec and AdamR, thank you both for your response! I appreciate it as this was holding up my build and can now continue.

    best regards!
