Wood Harpoon Drill
Intro: Wood Harpoon Drill
You want to make a calumet? A flute? A bagpipe? A blowgun? A didgeridoo?
You need to drill a very very long tunnel in a piece of wood?
You'll like this!
All you need:
- a flat wood drill bit
- a tube of aluminium or steel (with an inner diameter slightly bigger than the outer diameter of the extension of the drill bit)
- chemical anchor
- pliers
All you do:
- cut the tube to the size you want (mine's more than two feet!)
- put some chemical anchor in one end and on the bit
- slip the bit into the tube
- pince the end of the tube and push the bit a bit further
- let it solidify a few minutes
Now you've got the longest and cheapest wood drill bit ever!
Use: Make 'pumping' movements while drilling.
This allows you to evacuate the sawdust and avoid being stuck.
Use lots of natural oil to cool the drill bit.
I made a calumet with it and it worked just perfect!
Cheap, yak-proof, powerful, effective!
Enjoy!!!

You might want to check out data on the old wood bed gun drilling machines, too, if you want to make long but really straight bores.

Shrink fits like what balisticsquirel describes are often much more slip-resistant than bonded fits. It you choose your metals correctly, for example, a high coefficient of expansion tube, such as either aluminum or most stainless steel alloys, and have a normal tool steel bit (most tool steels have lower coefficients of expansion), have some linear barbs on the tool shank, then you'd more likely break the tool shaft or tube before causing the fit to slip when you assemble (very quickly) the cold bit into the hot tube. Note that you can ruin some bearings by assembling them into machinery with too much compression by the process described above, so consider the precision of fit that you need and what you have for components before you extend this process to fitting precision bearings.
