Indeed! If you continue on with it and aren't comfortable discharging it yourself, you can take it to a TV repair shop (if they still have them anymore?) and have them discharge it for you.I don't have any tips for the actual construction other than BE CAREFUL!!!
CRT monitors (especially large old ones) have capacitors in them that can stay charged for a LONG time after its been unplugged. Just like TV sets.
It seems like a fun idea, but if you have any doubts about your electrical knowledge or the workings of a CRT monitor don't mess around! Totally not worth it.
