Concrete Coffee Table || DIY Concrete Mold Making

[@BrainSlugs83]

Instead of throwing the silicone mold out, cut it into little cubes. You can reuse them during your next silicone pour (of any size). Just fill up the cavity of your best pour with the cubes, and then pour the silicone over that. You will use much less silicone mixture that way.

[@jameslucas3161]

Instead of throwing the mold out he could've broken the wooden bracing off before releasing the concrete base then made new bracing using fibreglass with a split in the middle so it can be removed and put back together easily.

[@kameljoe21]

@@jameslucas3161 With a bit of though he could have built a frame to hold the mold and then built a custom frame for the inside and pour another silicone mold for the inside. Then a custom X with 4 pins in them for the dowels to hold the top in place. Some wire mesh set in the middle of the form should be more than enough to keep if from breaking. A concrete vibrate tool to get the bubbles out and you have a mold that can be broken down and used again. The time and effort put in to this is enough to build a couple dozen tables of a number of colors and table tops and sell them for around 500 to 1500 dollars depending on the wood type and design top.

[@vectoredwolf]

Came here to say the same thing. tyvm!

[@8BitLife69]

For people looking to do similar, use ALGINATE instead. It's a throw away molding agent. Instead of wasting $1.5k on silicone like this guy did only to throw the mold away, alginate would have cost a quarter of this, and you can throw it away after, it's just a seaweed mix.

[@jamesmosley7794]

Nice project. The best part is being your son helping with the project. You also have a beautiful dog.

I was in the middle of writing an email asking if I could drive myself to Oregon to pick up that mold you were gonna throw out, when I saw you cut it up I sighed and discarded the draft lol. Great work, it looks awesome!

[@ielektra]

That mold would make a great outdoor planter as well. Very cool.

[@HobbyHopperJoanne]

OMG I love that idea.

[@DD47N1]

Loving the look of the table! That's alot of work but totally worth the effort!! Just FYI, you can take that used silicone, cut it up and use it in other projects. You can add it as "filler" when you have another large pour and it will save you a ton on new silicone! Anyway, loving your saltbox table and have a great weekend!

Could you use sand for the mould like you do when making an outdoor pizza oven?

[@DD47N1]

@@barneybarney9124 I've never tried that myself, but seems like it would be almost impossible with the fluting. I don't think the sand would maintain the ridges.

[@davidswanson5669]

Why don’t people use similar “aggregate” in their initial molds? Does it have to be actual cured silicone to work as filler, or could you use something like styrofoam?

[@inspiringbuilds]

It’s awesome that you got your son involved, we have to teach the next gen! Using a reciprocating saw without a blade to remove the air bubbles is my go to as well. Great innovative build! 👍

[@markdouglas9521]

Just wanted to say, I love your videos. You're clearly very knowledgable and always doing something interesting, but the sense of humour and willingness to show your mistakes you bring makes you a favourite. Thanks for doing what you do!

[@danielc6779]

Very interesting project. Not sure if you see these comments or not, but I definitely recommend some kind of sealer on the concrete for when the first spill inevitably happens.

[@loopinnerthe]

I was going to say that...

[@brianreddeman951]

Yes, concrete absorbs everything :) Speaking from experience.

[@loopinnerthe]

@@brianreddeman951 Maybe Jason is planning to invite some less favoured relatives around.....

[@tonysmith8779]

It's not concrete

[@petern1328]

If you do decide to scrap the silicone mold, don’t just throw it away - clean off residual mold release, cut it into small pieces and store it. Next time you make a big silicone pour (preferably same brand and type but mixing can work), you add those pieces as bulk filler, adding uncured silicone in between, thereby making substantial savings on fresh silicone. It does not negatively impact the new pour and the fresh silicone will fill any cavities as usual. You can reuse it the same way several times. is standard practice among many artists (in e.g. ceramic slip casting). Great project, thanks for sharing!

[@BLBlackDragon]

Mike is the expert in concrete furniture, and GFRC is the way to go. Hoo! Talk about "Concrete Christmas." That is gorgeous. Even though it's indoors, you should seal the concrete

[@DIYHGP]

Jason, what a beautiful table. have you considered putting a coat of silicone between the concrete base and your carpet so the lime in the concrete doesn’t leach into your carpet

[@timothyeliason8844]

I saw your IG post on the table saw kickback.... thought that you would cover it in this video. I appreciate that you have talked about shop safety in the past and was a little surprised that you did not cover it in this video. All that aside, great project. I really like how it turned out. Thanks for sharing!

[@lordkandar]

The first time you experience kickback really makes you understand table saw safety due to how scary it is. My first time was about a year after I got my saw and a big chonky piece of wood spun when it mounted the blade because I forgot to reinstall the riving knife after removing a dado stack. You better believe I never forgot to reinstall it ever again.

[@JTWoodworks]

Turned out looking pretty nice. Good choice trimming down the top

[@rossk4864]

A section of sonotube, of the appropriate diameter, might have worked pretty slick for the interior cylinder form (also larger sonotube may have simplified construction of the outer cylinder) although it would have required a different technique to attach the top. I also initially thought you were planning on applying the dowels on the interior of the exterior form and the concrete base would have concave cylindrical flutes, instead of convex flutes, which seemed aesthetically cool to me. However, your final product looks very attractive and the closest thing to perfection that I could imagine! Great job and lots of good information!!

[@GutDing]

Love this table! It really suits the space well and looks amazing. I would consider making the top removeable and reuse the dowels to clad out the inside, then it could be used as a hidden bar

[@paramagic661]

Nice! That mold would make an awesome fire pit also I think

[@Suzieq5446]

Your patience is a virtue and the end product shows your handiwork. Beautiful!!

[@brianakins83]

So cool. Love it. If you haven't thrown the silicon pieces out, perhaps stick a section under the coffee table so you have it if you ever move or if you want/need to replace the rug, so you'd have a way to safely stand it up. Monday morning quarterbacking over here...

[@maryisme247]

That's pretty cool! I was thinking maybe affixing a couple round slick steel furniture glides on the bottom, they are pretty low profile and you could scoot it around easier if you wanted. I love it when the foreman shows up. He's getting so big! Next project, making furniture for the treehouse. It needs something up there for sitting, eating snacks and playing video games.

[@thefirstwhizzkid]

Dude! This is great! Way to think outside the ramekin!

[@cadthunkin]

I love the results. You had the vision and made it 1st try, that is skill. I'd like to see this redone, yes, make another, but really minimize the silicone some how. I'm thinking build up a layer on the mold (center part, not outer), then fill the rest with concrete so you just need a thin layer. Its all you, good luck! lol

[@alexsnave]

Hi mate, ive used lots of silicone in the past. Next time before your concrete pour, take the silicone out the mould and then slice the silicone in a zigzag pattern. Silicone is very forgiving and will go back together very easily. Meaning when the concrete is set you can simply peal the silicone away from the concrete. This also then gives you a mould you can reuse over and over again. You can use ratchet straps or tape around the outside to hold the silicone in place without a wood form! Hope that helps :)

[@justinbudreau3808]

save your scrap silicone and cut it up into chunks, it can act as filler and reduce the amount of silicone you need for later pours.

[@azpilotd4351]

Great outcome, love it. I would love to know how much this actually cost you to make?

[@siem8160]

Beautiful coffee table that I love. A mounting of this superb oak top on the invisible hinge would have been very useful to take advantage of the space inside. When I bang my foot or knee violently into mine, which must weigh around twenty kilos, I complain for two minutes and that's it. With this concrete, I'm in for a fracture, but I'd still love to have a table like this.

[@troyqueen9503]

For doing curved pieces, get some bendy board, it’s plywood with the grain all running in the same orientation and this allows it to bend.You can get it with the grain running the full 8ft or 4ft direction.👍🏝️🇨🇦

[@johnnyb95678]

Always appreciate your no fear approach to trying new things. It turned out great.

[@DankBlueBird]

I wonder if you could cut the rest of the mould a bit to use again but for some matching side tables for your table.

[@rossransom]

I enjoyed watching this video, and thank you for taking the time to make it. Your patient way of explaining how and why adds immensely to the content.

[@FullSailDale1]

A compression bit is designed for cutting through the full thickness at once, giving inward shear to both top and bottom simultaneously. If you don't cut deep enough, you're effectively using it as an "uncut" bit and will experience tear out. For what you're doing, a "downcut" bit will eliminate tear out on the top and give you the "guide" surface for your compression bit in the hand-router... which is much easier than trying to cut the entire circle with the circle jig (sorry, that's a pet peeve of mine). Nice work... I enjoyed it!

[@hagiwoodworks7759]

$2000 mold for the base plus labor “ I’m not made of money “

[@robertshank1131]

That was my first thought. That's a lot of silicone, I bet its expensive... I counted 14 bottles (x2) for the pour, the link says they are $106 each.

[@mus_xr4653]

[@ShadowoftheDude]

To be fair, it is tax deductible.

[@danielanthony1054]

you can also cut up the silicone into small pieces and use it as filler material the next time you build any silicone molds

Check out a concrete supply store next time for form liner. They have a bunch of different designs. Rip it to size, line your ply wood form and pour. Or look at concrete stamps.

[@Hefty54]

The overall cost and time doesn't equate to an unreal looking coffee table. Wow tools most DIY's can't afford to buy. Ok you have it built if and only if I was going to craft this table I would have raised the oak top a bit and install a sub woofer in the round center making it a duo purpose coffee table sound system. That would be a nice touch.

[@rossbower7966]

Absolutely love this, I think is the top was a few millimeters (1/8 inch) above the base it would get a nice shadow line and look even better

[@samandoria]

There is a technique where you paint on the silicone, first liquid silicone then when you get a nice detailed first couple of layers you thicken the silicone so that you can put on thicker layers. Then, to save on silicone and so that the silicon mould can be thin enough to simple peel it off your finished piece you make a rigid outer shell. For this you could use plaster bandages or even better, fiberglass and resin to make rigid panels around the silicone mould. Would probably work for this and be way cheaper. A bit more complex though.

[@fidelcastro5248]

Beautiful job, man! Now you also have 75 oak hammer handles :)

[@imdebmccann]

I love the coffee table! The holes do make it look more like concrete than a painted faux surface. I think you could sell your silicone form locally for the cost of the silicone. There are definitely people who would buy it and make the box for it themselves. Your labor would be lost, but it would still be lost if you tossed the form in the can and at least you would recoup some of your $$.

[@berightbyack89]

I am very grateful that you exist man :) need to read a bit more about the shaper origin as it still looks like dark magic to me

[@mich89626]

I’ve had an idea of using silicone to make a concrete nightstand with a wood top. Thanks for the inspiration and also the info on the concrete company. They might come in handy. Also, if you ever remake this project or if someone else does. You could make the inside a little cleaner and have the top be removable and you have a nice storage space for throw blankets or an extra bottle of bourbon for when you are watching tv.

[@alisonrowlinson4139]

Really nice the project that gets harder the more you look at it

[@BikeJackass]

You could use something mixed in the silicone to reduce the amount needed, what you used depends on thickness of the mold, ping pong balls, packing widgets etc.

[@Papasqanch]

You can cut it into chunks and bag it. If you do another project that needs a lot of silicone you can fill the mold with the chunks from this project. Then you can pour around the filler chunks. It makes it so you don’t need to use as much new silicone.

I had "Fold in the cheese" stuck in my head watching you put the glass fibers in. Also, I think you can save your silicone and chop it into bits to use as filler for other pour projects! I saw someone else do this when their first attempt went south and they were running low on silicone.
