DIY Build Earth Auger - Post Hole Digger / Dig Plant Holes

I didn't want to pay $100 for an earth auger that could easily be made in an hour or two, so I made one from scrap. You can see the process in this video.
If you want to make a post hole digger as well, an angle grinder and a welder are required.
I couldn't get any larger sheet metal, so I welded plates from narrower steel strips. It's easier to machine afterward.
Drilling is easy as long as the ground is moist and free of larger stones.
It takes me 5 to 10 minutes to drill a 40 cm (1.3 ft) deep hole. The diameter is 16 cm (6.2").

At first, I wanted to rent a power auger from a rental shop, but eventually I was tempted to make a manual drill tool. Does anyone have experience with making similar tools? What have you crafted lately?
I also tried attaching a drill to the tool, but 12v wasn't enough. Hand digging is good for the muscles, though! :-)

Always wondered would a mobile home tie down work?

What is the name of that store you went in first ?

<snicker> Don't forget the $150 to $200 (Minimum) welder you'll need.

so many things wrong with this build, pitch to deep, digs to deep will get stuck, clearly u can see its just picking up already loose soil, also used in supper loose soils not for realistic situations.
