Since '04-up E150 16" rims are too hard to find at a reasonable price, 16" Dodge rims can be substituted by opening the center hole to 3.45". If a lathe isn't available, the truck can be used as long as the jack stand is solid & the other tires are chocked SUBSTANTIALLY. Dodge rims have ~1.5" more backspacing than Fords, so spacers may be required. I ordered a set of 2" spacers from eBay, and they work well.
I used a 15mm Craftsman open-end wrench to set 5 cheap lug nuts the same distance off the hub face (backward) so the rim would clear the stickout of the axle. There were ~4 threads left for the outer lug nuts to grip, and just enough room for this burr to work. An easier way would be to buy the 2" spacers first, since they have no stickout.
After some practice, I found full-speed & very light pressure on the die grinder worked best. The truck is idling in Reverse (if I had used the L rear location, it would have been 1st gear). It took ~25 minutes per rim, and I was covered in microscopic steel needles. I should have worn gloves, long-sleeves, & pants, but it was too hot. Ear plugs & goggles are mandatory.

But the BACKSPACING on each of those may vary, so spacers might be required.

2 in. spacers were required to push the tires out where they belong on my truck:
