thank you for making this longer and explaining more

wow , im always impressed with what Tom does . Ive seen it done other ways but this way was soooo simple awesome job!!!!!!!

Great show, love what all do thank you so much for your time and knowledge

Tommy, you are a genius. It seems like you always have the solution to a problem and you present the solution and make it look easy

Very creative solution. Thanks

Thank you guys so much for this amazing video!! I've been thinking of trying to do this in a hallway much like this one in my basement and thanks to you guys I know exactly how to do it now 😁

That is pretty cool!

Tom Silva is the man.

That was amazing

Nice trick !

That IS A slick trick, Tommy!!

I swear if I knew a quarter of the stuff Tommy knows I'd he happy as hell

Nice work

Very cool Tommy !!!

Excellent effect all round (groan). Interesting method of drawing the ellipse. An alternative method is string and nails and use a pencil to draw an elliptical curve. (And easy as to try it for yourselves, without needing to knock up the timber battens of course.) As for the bending or curving of the drywall material then you need look no further than your own Gypsum Association. They have produced an interesting paper or method statement : GA-226-2019 This Paper illustrates methodology for bending of both concave and convex surfaces (from pov of viewer). Plus a table of radii possible using the various thicknesses. It describes also "wet" bending; by water misting one of the surfaces about 10 to 15 minutes prior to installation. If a very tight concave bend is required then it is possible to score the face in tension (with a Stanley knife, say.) Even more amazing is it is possible to form a cylinder using gypsum board Type of fixings and centers included too. Amazing how simple (relatively) it is to form plasterboard/sheetrock/drywall. Probably goes without saying that you take your time to get the result.

That is pretty cool! 😊

Neat trick

This video is a reminder that Tom is the man.

I just tried this. It works. Have an extra set of hands and make sure your two sticks are tightly secured together.

Nice!!👍👍👍👍

Tommy had me worried when he said "Slowly bend the drywall". Nice job.

Muy bien

Pretty cool invention with that stick.

Nice job when we do it in the UK we spray water on the plasterboard first to manipulate it into shape 👍

Tommy just blew my mind!

Tommy with that awesome trick!

Masterful stick trick.

Tommy you are by far a master builder, are sure you're not a free mason? Because you got a lot of special talents.

It’s not an ellipse. To do that search for the elegant eclipse in This is carpentry. They use a string and the focal points of an ellipse. But yes Tommy is the best. His practical guidance has saved me so many times. And he is just plain fun to watch!

I'm impressed. Didn't know drywall would bend that way.

I've seen the round walls put in.. using spurs on the back side and weting the board to help it bend and take forms.

I've never seen an arc drawn that way before, very interesting! I think the inscribed angle theorem means that the curve is the arc of a circle, and that when one stick is held horizontal, if the other matches the pitch of the rafter, then the circle will be tangent to the rafters. Cool!

But is it a circle or hyperbola? I'm going with the latter but happy to be corrected.

I use bendable plywood and wet Rock ( they have bendable sheetrock too)...The plywood gives you a great screw in surface, If you can layer it/ all the better...

Did Tommy use a standard 1/2” piece of drywall or is there one that is more flexible? I’m surprised the drywall didn’t crack

3/8" for sure. In the old days they would use thicker drywall, but they would score the back to create controlled relief points so it would flex/crack but maintain the paper covering.. I'm not sure which way is better, because even this way, I'd wonder if you'd have screw popping (where the screw pulls through the back of the drywall) eventually. You'll notice they also used fine-threaded drywall screws for more holding power, and I'm not sure if they put in more than a standard panel but I'd probably add more screws and hope for the best. The problem with the thin drywall is over-driving the screws, Gotta say those Festool drivers handle speed variability really well it seems. See how they did it here: kzread.info/dash/bejne/d2yavK6GZbbFlNY.html

Drywall is heavy when your helper is taking forever to find screws

impressive way he made the arch. I think though you would have gotten the same arch with a much simpler way: just take a scrap piece of trim wood that is thin enough to bend like shoe molding. Pressing the trim against each of of the nails and just push forward the middle should also make a natural arch as well.

As I said in another comment, at least in my area a wooden ceiling wouldn't pass the fire codes.

Great solution - however they should have talked about the characteristics of the 'dry wall' material and model their arch on it. I believe that if 'dry wall' is steamed it will be more pliable and retain the shape it is formed in to once it has dried.

Para hacer curbas es el mismo proceso

Is that 3 point arch? Or eleptical arch. Looking great.

Wondering why Tommy decided not to also use a few dabs of stud adhesive between the timber and the back of the drywall sheet to maybe prevent the screws from popping out over time.

@RadDadisRad

The moisture in the air will keep the drywall formed to fit. It helps if you use a wand sprayer and spray the Sheetrock with a little water. It softens the gypsum and it’ll bow easier and not crack as easy also.

@@RadDadisRad I wonder if you sprayed the scored gypsum board with dilute PVA then the PVA would harden in the "set" sheet of plasterboard. I have used dilute (5:1) PVA in powdered plaster mix. It appears to help with the forming of the plaster mix, plus does not dust off when dry.

@DR PHIL I have done this taping of joints ( typically we use a "scrim" tape, which is a manmade fibre mesh with an adhesive backing, about 2" wide or so) and then using multiple layers of a fine powdered filler plaster, sanded smooth between applications until all the depressions filled. Typically the finish side of a sheet of plasterboard is thinner on the edges to allow a skim of plaster to cover the scrim tape. We are very much into wall paper coverings, so then either single cross line the wall with a off-white backing paper, (slightly wider than the finish paper so as to avoid the seams lining up) or if desired double cross line a wall before the final coverings. This means the second layer of backing paper is applied horizontally. (In Victorian or Edwardian terrace houses, not always well built and sometimes just thrown up, we must resort to a single layer of woodchip paper (with "real" wood chips in the fibres) which is so heavy it more or less holds the hundred year old plus horsehair fortified plaster together. Sometimes you find bugs living off the horsehair. Usually the ceilings in these old houses are lathe and plaster and appear to defy gravity for decades. These ceilings sometimes papered as well. Some folks use an anaglypta paper which has an embossed pattern. This too is a very heavy weight paper. Then the paper is painted with emulsion, or sometimes gloss paints.(Each to his own ...) We have a lot of the not particularly desirable Victorian/Edwardian housing stock in inner cities and these are usually all the first time home buyer can afford, hence a rough and ready approach to decorating. People try to move on as fast as possible to the more desirable "leafy suburbs" surrounding our towns and cities. (A typical two up, two down terrace is a bit small for when children arrive.) If a wall is plaster coated, and in good condition, then just an emulsion paint. Newer build house with internal timber framed walls are plasterboarded and skim coated with plaster. Then either emulsioned by the builders when first sold, then perhaps wall papered later by the new owners.

Wet the back of the drywall and let it hang over a sawhorse while you go to lunch. Comes out much better when installed.

So the angle of the trace sticks has to be adjusted to fit an arc inside the rafters?

-Hey Tommy I'd really love to know why you marked both sides of both of the rafters on your template?- Don't worry they answered that question at 3:50.

Take the original template and stand it up on its edge, curved side down. Start at one end of the drywall and roll or rock it along the drywall (like a classic rocking chair). Mark the end and make your cut.

How do you make that stick tool to guide you on making arc do you play with it until it looks good ??? Also would you have to consider the drywalls bend strength? I think you would but also if you could show a video without the drywall amd instead plywood also why not make blue prints to hold stairs without dealing with barrel cieling arcs

Pro tip: you can also dapen the drywall with some water... NOT SOAK, but dampen... It'll bend much easier and less likely to crack. I'd use a sprayer. Let it soak in.

Not to deep and nice and slow she said

Wouldn't 1/4" plywood work better? It won't crack. You could use two layers of it, and you could score the back.

Why not double up brackets and bead board that curve?

Wouldn't it just be easier to use a thin piece of wood as a batten? And it would let you adjust the arch easily.

Suspect it all depends on thickness of the plasterboard and the radius you're hoping to bend around. Scoring the side in tension, on a concave bend, say, is still perfectly. valid.

String not tied up in a loop as only half an ellipse. If you Google up how to draw an ellipse with two nails in the foci and a loop of string no reason why not trying it for yourself. The curve Tommy drew is only a sector of an ellipse. The inside surface of those two rafters is the limiting factor for the curve.
