What is a mirror lock by the way, and does a carbon fibre tube need it much given its extremely low coefficient of thermal expansion, or is it mirror flop caused by different angles of the tube that needs addressing?

SCT's are focussed by moving the primary mirror, the mirror lock locks the mirror in place so it can't slip or flop as the tube is moved... the carbon fibre tube won't help with this.
