How to lift the corner of a heavy stove with a bottle jack
In order of decreasing likelihood of success:

Wrangle a couple of friends, order pizza, have friends help lift the stove, have small child wriggle between the legs and put the floor protector disk in place. Feed everyone some pizza and possibly some adult beverages (if that's your thing) for the adults, and youth beverages for the youth.

Use a long &quot;spud bar&quot; (I have one that's 6' long) or a long pry bar (3' or so). Find something solid under the stove that will take weight (avoid trim, thin vertical side panels, etc). Use a block of wood as a fulcrum to lift the stove corner. Have a helper place the floor protector under the stove. Feed the helper some pizza &amp; a beverage.

Weld together a steel frame to fit inside the oven. Put a steel plate on top of the frame. Weld a vertical framework that the platform will attach to at the door of the oven (with diagonal bracing reaching to the inside back of the oven). Place the bottle jack underneath the steel framework. Lift the stove (the framework will spread the weight across the flat plate against the roof of the oven, minimizing damage, unless there's an electric heating element there - remove if necessary). Insert floor protection disk. Lower the stove. Do something with all that extra steel. No pizza necessary for helpers because no helpers needed (except, perhaps, for moving the lifting framework into place - feed as desired).


Yes, that last one is somewhat facetious. However, I think that's the only reasonable way you'll be able to use the bottle jack to lift the stove without damaging the stove.
