<div>CNC machining is widely used for handbell production in the US. See <A href="http://www.youtube.com/watch?v=1lYEpRZjfaI">http://www.youtube.com/watch?v=1lYEpRZjfaI</A></div>
<div> </div>
<div>This has been brought into use for tower bells also (particularly at Eijsbouts). However the final adjustments are always done by hand.</div>
<div> </div>
<div>Computer aided design of bells has been in use for many years now, and can be used to cut (via CNC laser cutting machines) accurate strickles ready of the production of cores and copes.</div>
