I have a beautiful post of reclaimed wood and I'd like to make it into a lamp. Not sure how to do this but I know the first step is to drill a hole all the way through it lengthwise. What is the tool and technique for this job and might I find a woodshop that could help me with it?
Long (18" and longer) drill bits do exist. If the hole is wide enough, bit extensions are also usable.
However, there's also a simple-but-elegant cheat. Cut the piece lengthwise, rout a channel in one or both sides, glue back together. If you make a thin-kerf cut, and are careful during reassembly, the glue line can be nearly invisible -- especially on straight-grained wood with the cut aligned with the grain lines.
Depends on the diameter and length. You may be able to use a conventional type bit and go half way from each end; I have made about 16" hole in 2" diameter that way . An expensive alternative is a gun drill (bit); it does not have spiral flutes and only cuts on one side of the point , and it can drill gun barrels. If the diameter is "large", a auger bit may do it, they make a pretty straight hole , but I never used on for this.
