Topic tags/keywords: c-channel c channel table top breadboard breadboard ends jig question tip

I want to start adding c-channel to my table tops for two main reasons:

Avoid doing breadboard ends (dated look and take a long time)

keep my tops nice and straight without ever being seen

I know i can buy kits online like this:

however, I’d like to make my own by just buying it at Home Depot and cutting the slots myself. My question is how would i go about making the slots? I’m thinking a metal cutting drill bit to make the opening followed by a Dremel with a cutoff Wheel to connect the holes. Would that be the quickest way to do this?

I think you’ve got it. At least that’s how I would do it. Or…just take an angle grinder and cut the slots. They shouldn’t be visible on the finished project and as long as they allow the screws to float they should be good.

if the slost are not going to be visible, an angle grinder is the way to go. start with a cut of wheel, then an 1/8 inch disk, than a 1/4 disk. if you need it bigger than a quarter you will have to come up with another idea. or look online for thicker disks, 1/8 and 1/4 are the only ones ive ever seen, not saying you cant get thicker but you probably cant and ive never seen them.

There are several types of steel channel with slots pre-cut?
Such as:

Common version is called Unistrut by electricians, & sold at BORG.
