TIP ... at time 8:39 if you screw the insert into the wood without glue first then remove it and use thin CA glue to coat the threads , let dry . The threads into the wood will be very strong . I found this out building RC airplanes. I also found that while applying CA glue the way you did , the glue will dry very fast and it will sometimes be hard to get the insert completely into the wood before the glue set up. But beautiful job on the top

[@jimmyz1686]

why is the glue even needed?

[@goodboyringo9716]

@@jimmyz1686 ... Thin CA glue is used to strengthen the threads. Screw the bolt into the wood making the treads then remove it Now, use thin CA glue in the hole , let dry ! Then screw in the bolt for very strong fit.

I installed my first pair of C-Channels today from bidwellwood. I was pretty impressed with the quality! I was honestly a bit nervous about the operation (not a lot of router experience), but I took my time setting up, made several passes. and it worked out really well. Thanks for this tutorial! It really made the whole thing way easier.

[@Brandon-cs8gw]

The c channel also protects your joints. Just because you glued them together doesn't mean the bond was 100%, even if you got good coverage. When me & my dad were making my custom desktop from solid alder, we lopped off one end, & actually removed some of the joint in order to get the length I wanted. It was no big deal, as it barely showed after some decent sanding, so for a little fun we set them on the ground & beat the shit out of them with a hammer to see what failed first. The joint or the glue. Obviously, the joint busted open until we got to the last one, & no matter how hard we hit that wood, it wouldn't give. Installing c channels is an excellent way to insure your joints never fail, if something ever happens, like you accidentally drop the desktop on the ground, then you won't have to worry about a joint failing. The c channel holds them together~

[@NorthwestCraftsman]

Phenomenal video as always. Thank you!

[@Cor97]

But how about the question in the title of this video: do you NEED them. Do they actually prevent warping of the wood? And if so, what is the contribution of the C-channel and what of the cut you made for the C-channel?

[@SirCanuckelhead]

The top is what needs them, and yes some tables really do. Also it is one of those things, do you want to wait and see that you did need them, or install them and never be an issue. The c channel is metal and does not warp and bend like wood does. So that is the point of it, to be rigid and not let the boards do what they want, aka ruin your top/table. A big top made of wood can not be thin, so the cut out is fine. If you try for a real thin top, then you are asking for failures down the road, warping/splitting. Have to be real careful with moisture, etc. Do you NEED it, no totally. Will it make your tables better and last longer? Almost 100% on that. There are a few times where you get the perfect wood that has no moisture and barely move, but those are rare and not the norm.

[@Cor97]

@@SirCanuckelhead Thanks

[@SirCanuckelhead]

@@Cor97 no problem, there are exceptions to every rule and each wood has it's own needs. So diff methods can be used, like doing a wood trim. Just the bigger the slab the higher chance for warping so bigger need for support/c-chan.

Do you think yous guys at Bidwell could make a C channel that attaches to the top horizontal of a leg assembly (for a table or desk top), on center, and also has offset holes to attach to the desk/table top to keep it flat? that would be kind of cool

[@WalkersWoodworks]

Ya probably so.

[@pnwoutdoors8873]

Hmmm… why not set the depth for the channel AND the flathead screw we’re using to to attach to the slab, to avoid spacing issues with flat surface mount or to prevent mounting issues with legs should they overlap.

[@thebackyardgriller9076]

[@liammcleman8450]

Hey Brandon, thanks for the great video. I’m new in my woodworking journey and was just curious if I routed the tops of my legs which have a 80mm x 4mm thick steel flat bar connecting them would it have the same effect?

[@pilgrimhillreformedfellows2076]

Thanks for this video! Question, why are the threaded inserts necessary? Could you use a screw/washer and distribute the pressure similarly? Thanks!

[@adamsodowy2793]

Does the fixing in the middle weaken the worktop? at this point the tabletop is cut across almost half the thickness, won't it start to sag in the middle over time?

[@swolleneyes]

same question. i would imagine this makes that section very weak as you pretty much scored through a large portion of the wood.

[@seanjoshua7972]

Great video. You might wanna use a drill guide, next time, so you make the holes for the threaded inserts straight. It looked like you were going on at an angle there bud.

[@JordanPLorenzen]

Great video Brandon, I'm currently working on my first kitchen table and I'm in the process of putting in these C-channels, but I'm concerned about how they may reduce the strength of the overall table. I understand that these help control warping and twisting, but should I be concerned about how these channels may weaken the table? Specifically on the ends of the table, where the legs are on the inside of the channels. Any advice would be greatly appreciated, thanks!

[@illegitimate0]

They would increase the strength of the table. They're steel structural members. They'd only be weak in a twisting direction, which a table top would only experience with greatly imbalanced loads across the different legs, and even then, it's so unlikely you'll have a moment that would twist two opposite edges in different directions without super uneven floors or some weird loading condition.

Hi, great video and explanations. I have a bamboo slab (69x39 and 1,5" thick) installed 8 years ago on a kitchen island. It started to warp in the last 2-3 years. I tryied a few tricks, like a wet towel to return it flat. It works but it warps again and even worst then before. We do oil it but we forgot to oil the underside. Can I install the C channels and bring it back flat using the water towel and tighten everything up? Also, on a 1,5" thick, how deep should I go to or what size of a C channel should I use? Thanks a million

[@tomfairbanks5567]

Have you ever put them on the top side of a table? I am in the process of designing and building a metal strap table. But I kind of like the looks of the c-channel and not going around the table top.

[@WalkersWoodworks]

I haven't. But I like where this is headed!

[@Donswoodshop]

Brandon - I'm working on a 14'x 4'6" black walnut boardroom table and have ordered 4 channels. Do you think it is enough? Is there a rule of thumb for the number of channels?

[@MrAmbe1234]

Do we use glue to fix the C-Channels to the table top? will the glue or epoxy add extra strength to the C-Channels in preventing cupping of the wood?

[@WalkersWoodworks]

Definitely don't do that. It needs to be able to move as the wood expands and contracts.

[@marcbrown6777]

Great video. What is the purpose of the inserts for the screws? Wouldn't the screws into the wood itself allow for the movement of wood over the seasons?

[@WalkersWoodworks]

The inserts allow you to use the flathead screws and are much stronger.

[@arthurised]

I also use inserts to fit table legs. They also provide the perfect solution allowing you to unscrew to move the table where the space to move (say thorough a doorway) to another location. Additionally, there is less chance of the wood splitting, thereby providing a more secure binding.

[@BooyaJoe]

Love the craftsmanship and thanks for the explanation. I don't quite understand the reason you do this. I've made a lot of tables over 6ft jointed maple, walnut, etc and glue and dowels do a fine job of keeping the boards level. Is this to just provide more structural integrity for cupping? If so, how do you manage this for smaller width boards in relation to your c-channel, or do you just make sure your board widths ensure each board will be screwed into the c-channel?

[@WalkersWoodworks]

Yep just a little extra insurance. Especially on tables that dont hve a full apron to anchor to. But even when they do I still do channel. 👍

[@R3dL1ght5]

would you recommend a piece length wise as well as the pieces you laid? In my instance at ~7' apart legs with a 2" slab desk. Thinking about making a grid arrangement of channel to inlay but maybe over engineering? thanks for any feedback!

[@WalkersWoodworks]

I'd use stretchers on the base for that.

[@sandru121]

Hello, I would like to know what dimensions it is recommended to have the part that goes into the wood depending on the thickness of the table top? For example, with a 4 cm table top, which model of C Channels should I use? I also attached a photo in which I specified the part inserted into the wood. Thank you and I await your answer!

[@kurtisallen741]

Super helpful video, so THANK YOU! How do you determine which size of channel you need for the table?

[@donuteater58]

How thick does your top need to be for c channels? Would you install it in a 1.25" thick top or do you it to be thicker?

[@WalkersWoodworks]

I’ve done it on 3/4” tops. Just have to get the right size channel.

[@joshevenson7604]

Do you purchase the C Channel with the wide holes already cut, or do you cut the holes yourself?

[@WalkersWoodworks]

He punches them before he breaks the channel.

[@yzebrov]

Is there any purpose to the inserts? Is there any benefit as opposed to using regular wood screws?

[@WalkersWoodworks]

They are much stronger

[@jonathansorof7763]

Great video, very clear and helpful. I am thinking about making a 7' x 4' walnut table (6" wide boards) that allows for the insertion of two 20" extensions, which means that the table would be cut in in half across the grain and have a sliding mechanism bolted underneath along the long dimensions with the grain. So each half of the table would be about 42" long by 48" wide. Do you think a C Channel on each side would be needed in this setup?

[@WalkersWoodworks]

That's what I would do. Check the description for a link to some good channel and hardware. 👍

[@joshuablanchard749]

I am building a table and plan on using c channels. My table will be 5 1/2 ft long and 39 inches wide and 1.25 inches thick. How deep should the c channels go? how much wood should there be from the bottom of the c channel to the table top so it does not loose strength

[@atommachine]

This is interesting , i have 25.. ply with a bonded 14 manmade floor on top total 40 mm when bonded , what size channel would make a difference do you think? i was looking for a 15 x 40 mm channel . It is to cover a 830 mm span hatch will be walked on so i don't want flex.

I’m building a white oak table 46” w x 9’ long (total length will include breadboard ends). Thickness will be 1” but I’ll be adding some 1”x2” edges to give it a thicker appearance. Do you think it’s necessary to have c channels if I have breadboard ends?

[@WalkersWoodworks]

No they should take care of it.

[@loganpickett1671]

This is probably a stupid question but I thought I would ask just to make sure. I am going to be making a 36" long murphy desk that comes down from the wall. I think it is going to be a bit long to hold its rigidity. So I was thinking that this idea might work. Will C Channel being laid perpendicular to the length of the boards keep the desk from bending the farther it extends? I was thinking that laying the C channel parallel with the boards would give me a better result.

[@WalkersWoodworks]

That definitely would help strengthen it. 👍

[@rhyswilliams346]

Could you use use 3/16, or 1/4" flat bar, instead of c channel? Thanks

@@WalkersWoodworks So if you had coffee tables that were under 5' you think it would be safe not to use them, I only ask because I haven't usually done smaller tables I'm wondering if I could go without using them

[@hullion]

Hi. I dont get something. You crosscut with the router two rather deep channels in parallel, at a mere 2-3”from each other. Then you mount an insert into the top 1” or less. Once tension rises in the wood, doesnt it just rip a chunk out between the two channels considering wood splits in that dimension pretty easy? I mean its just a two inch long piece if wood where the screw and insert applies all the pulling force, and the steel of course cant buckle. And if it doesnt split: doesnt that mean that the channel is not needed, as cupping force is insignificant/it doesnt cup anyway?? Thanx

[@user-lb7fm8fr8x]

If the table top is quite thin (20mm) can the C channel NOT be recessed, and be installed up the other way? Is the recessing for aesthetic reasons only? Or a structural reason?

It doesn't really matter. If you get the channel from Bidwell (in the description) they come with precut slots. 👍

The seller showed the top at 45 x 24 with metal plates (or battens, about 1/2 width and 22 inches long on the short edge of the table top) about 5 inches in underneath on both ends and one metal batten in the center. Similar to your c-channels but they seem flat and the screws leave no wiggle room for movement. My top arrived with only 2 "metal battens" instead of 3, with each on the ends, not center. The underside of the table top has a rough area that's uneven, I don't know the proper term and there are some cracks coming from it but only on the underside. On the top side it looks like a beginning of a large knot. I'm wondering if I should be concerned and return it? It won't be easy for me to do that, but I don't want to see anything happen to this tabletop after I go through the effort of attaching legs.

Is it better if i build the table top so that the end grain looks like a ‘frown’ instead of a ‘smily face’ because I assume that the slab will want to warp/twist in the same direction as the end grain? Therefore, if/when it does warp it will be pushing down on the steel c channels instead of (if the board was built flipped over) pulling on the threaded inserts and bolts. It seems to me the scenario of pushing on the c channel would better take advantage of the steel. Any thoughts? Thanks!!

I'd face the side down that may cup. But as long as the wood is dried properly you shouldn't have much of an issue.

0:38 I can't speak for the time you spend on this in contrast to the entire project time, but to do all three of those, I feel like it must take at least an hour or two, which is no small amount of time. I'm guessing based off the 10 minute video that only showed you doing one. Even condensed into a video tutorial length, that's 30 minutes for all three...so the actual time couldn't possibly be any less than twice that, and much more likely three to four times that, maybe even more. Doesn't seem insignificant to me. But as far as if it's needed or not, I have no idea...I'm speaking strictly about the time it takes to do it. Nothing else nothing more.

Yea probably about a half hour each.

@@WalkersWoodworks spending 1.5 hours while making it to make it stronger and last longer seems like good use of time to me and insignificant in the lifespan of the piece. If you were making something that lasts a short time, then that time because more significant. When I build, I build for life so my customers that buy my products/services, they know they are getting the best and it will last.

hello can you tell me where you purchased your c channel ? thank you

[@nicolemcpeak445]

does this help with bowed table with epoxy in the middle?

[@WalkersWoodworks]

I definitely put them in epoxy tables.

Just ordered the same threaded inserts for this C-Channel. What size Forstner bit did you use?

[@WalkersWoodworks]

I believe it was 3/8"
