I am wanting to make my own tiki torches, by drilling a hole 2 1/2 in wide by 5 inches deep in the end of a small log. I can't seem to find spade bits any bigger then 1 1/2 in, and nothing long enough to drill 5 inches deep. Can any one tell me if this is possible? Surely in this day and age it is!
You want a Forstner bit and an extension shaft.
The tool you need is a 2 1/2" Forstner bit. There's going to be a lot of torque resistance, so you may need to use a drill press instead of just a handheld drill.
- Drill with the spade bit then put the log in a lathe and enlarge the hole out with a boring tool.
- As above but put the boring bit in the lathe and bring the log to the tool. You'd do this if the log is too big for the lathe.
- Drill lots of small holes covering the area of the intended hole, then chisel out the remaining wood.
