I want to make a hanging chandelier with candles. The centerpiece is Technic Knob Cog . My initial thought was to design it just like the Big Ben Church bells (step 278). However, I don't think that technic pin with bar extension will interface correctly with the technic knob cog as I think it needs an axle to hold it right? So I guess I need a way to hang a short vertical axle from a very long horizontal axle (or set of connected horizontal axles).

I'll confess - my inspiration for that element in my answer to your 4 candles question came from set 10273 - Haunted House which uses it for exactly that purpose - instructions are here (180MB), it's on page 119:

Knob Cog and Axle with stop instructions

It uses a Technic, Axle 5 with stop to hold the knob cog up, and it's inserted into a Technic, Axle and Pin Connector Angled #1 that's hanging from a beam made from Axle Connectors 2L (Smooth) and Axle 2 Notched.

  • Good gravy, 180 MB for LEGO instructions? Wow. Thanks for noting that

  • Yeah, it's one big book. I thought I ought to call it out ;) Commented May 21, 2021 at 7:35

I just realized you can put an axle through the 180 degree connectors just like you can a technic pin. Then, you just need a bush or something above the vertical axle to hold it in place.
