Don't be so harsh, guys. It's a valid question that does not necessitate condescending responses. I read the forum several times a day and this question is very infrequently asked.
@Spen1818 welcome to the forum. Yes, you can hack up a daisy wheel kettle to add one touch but it's a lot of effort and you will end up with a sub par product to one that was stamped from the factory. The daisy wheel parts will also get in the way. I believe this is why no one has done the "conversion". The quotes are because it would be a mess of holes an cutouts. Alternatively, several members -myself included- have added strategically placed daisy wheels to kettles. That's a little more managable and you have a lot more flexibility of where you can put them.
It sounds like you want to use the kettle but want the modern conveniences of a one touch. My advice would be to procure a Black One touch bowl then use your grandpas lid/grates/legs/wheels/leg rack as a "tribute" or homage kettle. Would be sweet imo.
There's several members in the Minneapolis area- maybe they will even have one they can provide you for cheap. How far is that from you?
