I designed this tool (in fact a bit to mount on a drill or a router) especially for kuksa carving, but I can imagine it can be a great help for anyone who wants to drill big smooth holes in wood.
All you need:
- angle cutter
- heavy duty clock drill
- piton or bolt
- a few screws
- a piece or carbon steel
Step 1: Cut It Out
Never throw anything! Years ago I found on a flee market an old machete, handforged and perfect to 'turn into something else one time': perfect for this project.
Clean it up, and drill a disc out of it with a clock drill. Don't forget to lubrificate while drilling.
Step 2: Pitonize
Cut a groove in the top of a heavy diameter bolt.
Insert the disc, drill two holes in both (side to side) & smash a few autoscrewing screws or pitons in it to uniform the whole.
Dirty but effective!
Step 3: Sharpen & Ready to Go!
Sharpen the edges - on the counterclockwiseside, of course - and mount the device on a router or column drill.
Power ON, highspeed & go!
NO NEED TO TELL THAT THIS DEVICE IS AS DANGEROUS AS HELL.
WEAR GLOVES & HOLD THE PIECE WITH BOTH HANDS, IT DOESN'T MAKE A DIFFERENCE BETWEEN WOOD & MEAT.
Enjoy this tool.
Woodcarving will never be the same...
