That's AWESOME! Nicely done!!
Wish my Dad was still around so that we could build something like that. Enjoy your time with him while you can - sounds like you already do.
I'm curious, you said you used an OTG. How is the kettle supported? I figure the opening in the table needs to have room to allow for the kettle to expand as it heats up or there could be too much pressure on either the kettle or the table. Is the kettle sitting on some kind of gasket that allows for this expansion?
What happened to the handles on the base? Are they integrated into the table top? Are they being used to support the base? I thought about doing that with the table I would like to build but am concerned that the handles aren't designed to support the load of a full kettle, especially when in use; but, I'm no engineer so this is purely unfounded conjecture.
Thanks for sharing!
