To follow Al's blog entry, here is a quick little preview of a possible way to build a shop-made ceiling cord reel (basic idea)

Edit: I added a forum topic here to discuss the numbers and options for those interested in that potential shop project.

If youtube ever works, that is…

The idea is to have the wire coming from the ceiling into a fixed cylinder (the central brown cylinder) that is connected to the ceiling and suspended by any means, through the center hole of a metal lazy susan. Said ball bearing has its bottom attached to the fixed inner cylinder, and its upper par to beams that hold the outer (hollowed out) cylinder, which has a flat bottom. Not pictured is a crown pulley with a motor to drive it. That was a very quick 3D modelling, I will try to spare some time to make a small working model to validate the concept, expect something next week (on holidays at the parents’, where my shop and tools are).

If the end is plugged in, what keeps it from twisting the cord?

The fact that the cord itself is not rotating. In fact only the outer part rotates around the fixed center, which doesn’t move. As if you had one side of the cord grabbed in your left hand and you rolled the cord around it with your other hand.

In fact it’s exactly the same principle as some fishing reels: you have both those with a rotating barrel:

and those with a fixed one:

ok, got it. The cord could come up through the center, which wouldn’t spin. Good idea.

Exactly. I guess the commercial ones certainly work like that. I’ll have to open one to check it out (namely, my home vacuum’s). Just add a pyramid or a cone at the bottom to center the cord and you’re good to go.
I’ll try to get some plans and a prototype done. Along with Matthias Wandel’s gear generator software and a cheap $5 ebay geared motor and $7 power supply, we can get a shop-made one done. Hmm maybe time for some numbers!

Forum post here those interested in the idea, so we can brainstorm a bit and decide on the needs.

I tried to follow the Forum Post Link above but it gave me a “page can’t be found” message. Your idea will work, but I wonder why bother? I almost never need extension cords except when I do outdoor projects. Different situations and work needs I guess.

Lovely little idea and the beginning of a reasonable option to a $330.00 “Made in Mexico” cadillac ! If enough outlets are built into a normal sized home shop, extension cords are unnecessary unless you have to take your work outside for one reason or another. But for me own self, I would rather invest $330.00 in a couple cases of Reisling Auslese and be done with it. Go sodabowski ! I love shop built alternatives to everything (save…the Reisling Auslese of course !) (:-{0)

.
The hose reel is purchased AFTER the Reisling. I should have made that more clear;)
