Hi, no need to edit/change/amend any of the chain links. The handles of the ‘hammers’ push through three holes of the chain link: the two holes outside and the one in the centre. You only have to ensure the centre handle remains flush with the underside of the link so that it does not foul on the teeth of the gear wheel. If only Lego made a 25 or 30 tooth wheel. That would allow each four strike of the Westminster Chime to be separated by either a single or double ‘space’. As you are no doubt aware, the full sequence of quarter hour chimes is completed by two revolutions of 5 x four note sequences.
cool mechanism, I was wondering if you needed to edit the chain link pieces in any way for the hammers to fit because i may use a similar mechanism to this for mine. thanks
Hi there, what is the purpose of the fan shaped thing sitting on the free wheel? If the mechanism has to be energy efficient, wouldn't the air resistance take a chunk of energy away? Great work btw I love it a lot
It is a flywheel. It is a way of slowing down the mechanism. I have found there is a trade-off between overcoming inertia (for each quarter hour chime) and the need for the mechanism to run slower when it starts. The flywheel provides the necessary drag. I found using a lighter weight had intermittent results just starting.
Hi, I don’t have any instructions but I will try to post a lot of pictures. The timing mechanism is based upon a Kevronista UA-cam video. The chime belt is actually made of two chain links in parallel. Each chain has 25 links in total. I use an alternative colour link (reddish brown) on each 25 link train to line the two trains up which allows for four (or more) pins to move the striking arms. The chimes themselves are straight from an old clock - mounted vertically so that the striking arms are able to swing freely under the force of gravity. I aim to redesign the whole movement at some point - as a pastime project - to incorporate a quarter hour release mechanism and to integrate the hourly chime. My challenge to myself is to keep the whole movement(s) as small as possible - so a lot of trial and error. Basically, the build is built around a re-purposed Westminster Chime bar.
This is probably the best sounding and most compact Lego Westminster Chime on UA-cam!!!
Hi! I have been trying to build a compact Westminster chime mechanism for some time, and just discovered your beautiful solution! Very impressive!
I take that as a great compliment. Thank you.

Is the hammer part 6246 or 11402?
@@Greg032The hammer used is part number 6246b ‘Cross Pein Hammer’ - which is one piece part of 6246.

Ok I’ll keep looking at it
Can you make a video on how to make it?
