  Neat mods, very well done.  I've had occasion to use cartridge heaters
on two Empires and an Elektro.

  So, how did you do it?  Drill into the boiler and solder the carrier
tube in or mount it on the bottom?  Inquiring minds want to know.

Good Successful work,
Wayne

Hi Wayne,  the video describes it pretty well , use a step drill for better/easier drilling up to the desired size, of course make sure your centered  , I try to leave a minimum of 3/16"-1/4" off of the bottom for Good heat circulation.  I have an Indy X that I would like to make usable again, but the rear of the boiler is exposed,  I'm thinking of some kind of tube underneath to accept 2 cartridge heaters 😏
