Yes, the ferrite plates are 3.87" x 3.87" x .118". One plate should be sufficient to make one u-core (2 required for the VIC coil). I have not investigated the possibility of cutting with a water jet or laser yet but I don't see any reason why either could not be used to turn the plates into u-cores. The 8-10 week lead time slows the process down. If anyone knows of someone who actually stocks something similar on a shelf ready to sell that would be a plus.
