Lamp auger?

follow directions until proven wrong.........

How will you secure the metal cord tube?

Well, on the lamp I built I used a hollow threaded rod. It allowed me to attach the lamp assembly firmly to the rod then I screwed the rod into the opening of wood lamp body. If it ever comes loose I can always glue the rod into the lamp. the cord tube doesn't go all the way through the lamp part of it is plain wood. Since I didn't make the lamp hollow like a bowl or narrow necjk vase the entire tube is not needed to guide the cord through the lamp. All I bought for the lamp was the actual lamp ficture, the hollow threaded rod, and a doaner extention cord. I cut off the multi plug end and attached it to the lamp assembly after threading it through my turned body and the section of hollow rod I used. I connected everything up and carefully plugged in the lamp. It worked.

Might want to bore a 3/8 hole and discover that's what the fittings are threaded for. Means if you're going to take a tube threaded both ends as your basic design, you'll want the hole 7/16 or so to allow the threads free passage.

I got my start in woodturning providing lamp bases for a custom lampshade artist. The auger is used to drill the hole from top to bottom for the cord. The hollow threaded tube only has to go a couple inches into the wood and I used a 23/64" drill to widen the auger hole for that. That size allows the threads to get a little bite, use jam nuts so you can grab it with a wrench to thread it into the hole. I usually put a tiny bit of epoxy in the hole before threading in the pipe for extra security. Lamps are fun, every turner should have a few wooden lamps in their home.

What I am hearing is that I don't need to have the whole threaded rod go the legnth of the lamp, just the top. Is there any fire danger if I don't use the metal rod through out? Please excuse my ignorance. I've just been curious. If not, I'll just devise a coupler of some sort and run the wire down the bored-out hole. Thanks for your help. Let me know if there is any danger in doing this.

threaded rod to attach the socket to the lamp. I don't understand this coupler you are planning on using. Is it to join two pieces of electrical wire in the body of the lamp? Probably not a good idea. You should use a solid piece of electrical cord from the light socket to the wall plug.

If you mean a coupler to attach the rod to the socket, the socket should come with a threaded coupler as part of its base.

You should also tie a lampmakers knot(Proper term?) in the cord in the base of the lamp just befor it goes through the wall of the lamp. This prevents the cord from being pulled out of the socket if anybody yanks on the cord for some reason.

Yeah, what he said. No fire danger. Definitely do the Underwriters knot. I always hollowed the base a little bit so I had room to add a second knot inside the horizontal hole where the cord exited through the base.

Thanks Mike for the correct name of the knot.
