I find it funny that you need a drill to make the hole for the pump drill.
-
You can probably get a better result with a pump drill if you sharpen it directionally and just accept that one direction of movement won't drill
-
That’s cool, you could also use that to start fires maybe.
-
I can't wait until people 100 years from now look at the technology we're currently using and question how we ever got anything done with the tools we use today... The same way I look with anxiety and admiration at the tools used 100 years ago. Thanks for the perspective!
-
I feel like you could make a unidirectional pump drill by having the axel broken in 2 parts with unidirectional gears changing the direction the force when it turns the opposite direction.

I say I am a beginner and blacksmith I’ve seen stuff but I am impressed with your work out of a lot of people and experience Smith’s that’s a big compliment by the way keep doing what you do teaching people about history or whatever you do I subscribed a while back
-
Youtuber Clickspring has a beautiful interpretation of the pump drill as well which he made as part of the toolset hes assembled to recreate the antikythera mechanism
-
I always keep a pump drill in my shop there's just something so nice about how quiet they are
-
it's also called an archimedes drill. it's pre-roman
-
Great video, though you could've made ot from stone if you really wanted to start at the beginning. Grind a hole in a stone from both sides until the hole is just big/small enough that it will hold onto the stick you use as your shank and a piece of flint or granite should work for a bit
-
The pump drill is genius
-
YouTube showed me this series in exact opposite order at different times
-
The bow drill and pump drill can also be used to make a fire as well if you take off the drill bit.
-
I think if you made the bit into a sharpened spoon shape, you'll get a better drilling process.
-
The pump drill looks cool and fun tbh.
-
That pump drill is pretty cool, Andy!
-
Do that is actually sick dude
-
“Mom can we watch a johnny harris video?” “No we have johnny harris at home” johnny harris at home
-
For the pump drill I would try to make a thinner tip, possibly with another edge or two. That should help to reduce friction and let it drill straight through
