Extended length drill bits

I am needing to drill 30 - 36" into the end of a 1" dowel, with a half inch bit. Built a jug, centering etc not an issue. What I am unfamiliar with is a bit to go that deep. I tried starting with a standard 5" HSS and followed with an electricians boring bit, but that just lost center an blew out the side.A quick search on google showed various places selling long bits, many without the lead screw, which it turns out will cause tremendous damage in end grain . So I can locate a vendor, but wondering if someone might already be buying form somewhere.Does anybody have any experience with something like this? Perhaps someone has a source they feel is reliable for such things?Perhaps I am on my own!?markndawoods

has just what he needs, except in 3/8 and

5/16" bits.

When I used to build lamps, I would split the blank in half, run a dado down the middle for the wire, and just drill the end to the right size for the threaded pipe nipples...
