Old technology.
« on: Feb 07, 2019, 02:12 PM »
Came across this yesterday. It cuts a core instead of shaving its way thru the ice. Seems it would take a lot less energy than augers. Wonder why nobody refined/updated the concept.

the concept is still used for anchor points, but has open ends.

this auger looks easy to get clogged.

Wonder how you would clear out the ice core
Im sure its not like a hole saw where you use
the drill bit to push out the wood core

Well, apart from being heavy just to lug around, you have the problem of extracting the "core". It either comes up with the auger or it stays in the hole. Either way it's something else to mess with. Frankly, the modern hand augers really don't require a lot of effort to spin. I'm holding out for the Daffy Duck Martian blaster ice auger.

Also what would you do if the ice is thicker than the drum is deep?

How did it work, the hand and gas version?

Basically like a woodworkers hole saw. Cuts a ring and core is captured in the sheet metal.
From my use of hole saws, they developed a lot of friction and get very hot. That would be a non issue or maybe even a plus for ice coring. Now that I think of it thatís how they sample glacial ice. They used fluids like kerosene with core drills to drill into Lake Vostok, over 13,000 ft. of ice. https://en.m.wikipedia.org/wiki/Lake_Vostok. Talk about safe ice!

I assumed you have these core drill units.  I meant how did the core drills, gas and hand work for you on the ice?
