I worked alone yesterday finishing up a brake job on a KW. I needed something to round out the day so I went to repack a grapple swivel. It has a tiny bore, about two inches and it's a pain to get the packing down into the grooves. I asked Dave at MEB one time how he deals with stiff seals and he showed me his "fry daddy"- a deep fat fryer he loads with hydraulic oil, adjusts the temp, and places the packing in there to soften it up.
So I put a few inches of clean hydraulic in a Pyrex measuring cup and put it in the gourmet microwave in the office. The cup got pretty hot but not the oil. It was warm enough to do the trick and the seal went in easier.
Well, there's 3 seals to go so I thought I'd try putting the oil in a Styrofoam cup and see what happens. Nothing.The oil was cold. Then I remembered microwaves work on heating moisture so I added a 1/2 inch of water which settled nicely to the bottom of the cup. "This ought to work" I said to myself proudly and set the microwave to 30 seconds- just to be safe. After 20 seconds it exploded. I open the door to find a hot, steaming, dripping mess.
I laughed.
I told them not to build the office attached to the shop...

Don't try this at home.
