Is there a good or best way to bore an approximately 5/8" dia hole about 20" long up a table leg (end grain) for an electrical wire. I am afraid to use a regular auger bit with extensions because of the possibility the hole will wander out the side of the leg. The 37" long leg is cherry, 2 1/2" dia at narrowest and 3" dia at widest near the end of the hole. I could try it on one leg and if hole starts going crooked, then try another leg until I get one straight. I have 6 legs to try but would much rather just have one hole drilled up one leg and have that hole be straight and true.
If there is someone in the Tacoma Seattle area who could do it for me, that would be preferred. My thought was to find someone who makes flutes but from what I have found out, flute tubes are split and then routed before reassembling. I was thinking maybe gunsmith but they use metal cutting blades of smaller diameter. I found a bit on line that looked like it would work but was about $150. It had hollow shaft and solid 3" or so long cutting end same diameter of hole (to keep it aligned) with a V cut into it to allow shavings removal using compressed air that is somehow sent down the bit. I didn't look at it very close due to cost.
I have a bench top drill press I could set on my work bench, turn the drill part so it is over the side of the bench and then set the leg in the bench vice and give it a try with some type of bit. I have brad point bits and augers that might work using extensions. I don't have much luck using forstner bits for deep holes. Drill press is heavy and moving it off the floor (where I use it) is not easy. I would much rather drive 100 miles round trip than move the drill press. My friends are like me, old with bad backs. Matter of fact, the last back surgery I had was due to that drill press when I bought and moved it 3 years ago with someone helping. That person has told me he will not help move it again. Last time I moved it, I hired movers.
Thank you in advance for any leads or suggestions.
