Don't know if you really have your mind set on making a shovel, unles you just like using one. For many years I have used a scoop to pus snow around, instead of lifting it. A friend tipped me off to th SnoWonder, and it still saves my back, every time I use it. I actually, enjoy using it, and can easily clear my whole drivewa before my neighbor is halfway done with his, using a snow blower.
The only problem with the SnoWonder is that it doesn't have an engine
so doesn't make any noise when you use it.
Suggest you look into getting one. You won't regret it
