So, I click on the thumbnail because the tool looked intriguing. What could it be?
A winding tool? Some weird new tool for something that I might find useful?
Nah, it's a dull less effective hole saw!
Not to mention that it would take more time and effort to make than going to the store to buy one!
It isn't a "hack" if it is less effective in use and more wasteful to make
Com : Drill machine : Why turn a tube into a drill bit? Why not just get the right sized drill bit?
Why make a hole saw out of three bolts, when you could just use a hole saw?
The only hack I saw of interest was the first one for twisting wire,
but I wouldn't twist it until it broke off, because there aren't enough twists left for it to last long term.
So I'd just twist it down and cut it off with a 1/2" tail.
Also, couldn't I just tighten the wires down into the drill chuck itself?
Com: Home made tool : I feel like these are just wastes of money.
because your just buying more stuff for more money, when all you have to do is buy one thing for less money. also you just copy mr.gear
