Weed Whacker Auger

[G.M.T]

Here we go again. I've been watching all these crazy videos online of people building their own Outboard Motors using a weed whacker, they even build friction guided bikes as well as putting their own chain disk on the motor axle, and this is where my ambitions all started.
Instead of spending the money on an expensive Gas motor. I think I'm going to build my own out of one of my old weed Whackers. But before i waste my time building this. I want to hear other peoples input.

Do you think ill get enough torque to be able to get a clean cut through the ice?

Will this be fast enough or would going by hand be faster?

My main concern would not providing enough torque. I just know from personal experience that they can big down, and some do not like to start in the cold. That being said you have me very interested and if I had and extra one laying around I would def give it a shot. I hope I didn't rain on your idea to much, I actually hope you try it bc Id love to see if itd work.

Yeah I've thought about that, but I was thinking if i just take a little longer and not apply as much pressure I may be fine.

Anything is better than hand drilling thru 20" of ice. I'd love to see the results.

This is gonna take me a little while, I want to machine and weld the adapter to the motor shaft, but ill post my results when I'm done!

you need some type of gear reduction to translate speed to tourque , and enough motor to do the job....I adapted an earth auger to my mora its  a 43 cc 2 stroke and man does it cut,  it will almost jerk you thru the hole ....

I've seen snowcone's auger in action on Nimi and I can testify to the fact that thing rips thru some ice!  It's a brilliant idea and a great auger!

Well guys... I hate to say this but I failed miserably. At first I couldn't get the motor to start, and after a little while of tinkering with the carb and gas tank I got it started. So I thought I would work on the shaft. I found a way to hook up my earth auger to the shaft, and I thought I should test out my speed to torque ratio and give it a test on just plain dirt. It started going down well enough until I got about 2-4 inches or so in, I heard this awful sound. I stopped, and took it back to my work bench to take a look.
I tore the inner workings straight from the motor. Well it was worth a shot. Maybe I'll give Snowcones idea a try, or just give in a buy a new power auger.

earth auger power head rocks....
