Finally Finished one small part

[David NobleParticipant @davidnoble71990]

Thank goodness for that. It’s been a bit of a struggle! Just as well I enjoy it ( I think )

Clarification required. It appears to involve a chain driven cutter which is rather unusual.

[David NobleParticipant @davidnoble71990]

Yes you”re right Bazyl it does look a bit random.

I’m making an epicyclic clock which requires an internal gear wheel. I ‘invented’ the cutter assembly in order to reach inside the wheel. I tried using a round belt but I couldn’t stop it slipping so I changed it to chain drive. It has taken quite a while! Here are a few more photos which might explain it better.

Very impressive David. One of those jobs where patience is at a premium

[VicParticipant @vic]

Very impressive indeed. 😉

[Nigel Graham 2Participant @nigelgraham2]

Excellent!

I take it the cutter holder is reciprocated by an eccentric – the chain drive simply placing the drill well clear of the work-piece?

[David NobleParticipant @davidnoble71990]

Thank you gentlemen 🙂

Nigel, the cutter is  home made but yes, the chain drive is just to clear the work piece. There is a brass eccentric but that is just a tensioner.

[Nigel Graham 2Participant @nigelgraham2]

Thankyou David.

Ah… Ooops! I don’t know how but had managed to mis-read the photos to interpret the tool as some sort of shaper rather than mill!

It’s certainly very impressive work.
