I have had great success using a 4x8 foot sheet of white foam board. It is extremely light weight. I hung it from ceiling on strings attached to three binder clips or bull dog clips like show below. When not in use find a place you can store it flat. If it gets broken it’s cheap to replace. If it falls on a child no one gets hurt. The white foam is a good ...

Use Screws Anyway If it was me, I would quietly ignore "I am not allowed to secure it using screws in the wall." We are talking about a couple of screws here, which would leave ~ 1/4" holes, not cutting out large sections of the wall. Assuming it is drywall or plaster over studs, as opposed to a brick wall, I would put in two screws (~ 2" ...

Just about any type of plywood can be bent by cutting slots on the hidden side that leave both clearance for the bend and enough uncut wood on the front to support it. I once made some speaker cabinets that had a "horn" output similar to this: Your bend is sharper than the one I did, it looks to be 90 degrees, so you'll need to make more cuts to ...

I haven't built anything into a recess like you describe so this is conjecture. If you're fitting it into a recess and it is encased on all 5 sides (ceiling, floor, left side, right side, back wall), you could get away with not anchoring it. Since when it tips, it would strike against the ceiling. I'd also put wedges on all sides because it's probably not a ...

There are plywood products made for radius situations. Bendy plywood and Wacky Wood are a few names it goes by. Options are available from several manufacturers like Radius-bending Plywood or Flexi Ply. The layers are oriented in one direction making it easy to bend around pretty tight radius like yours.

It is impossible for the bookshelf to rotate forwards and crush anyone, child or not, the way you have drawn it. For it to fall on someone (who pulled on it, or climbed it) it would have to rotate around point A on this diagram: As you can see, before it becomes dangerously tilted the back will hit the enclosure at the top and stop it tilting further. In ...

Anything is possible, but this falls under the Why On Earth Would You category. Removing and reinstalling a toilet is a fairly simple job for even a novice DIYer. Don't let that intimidate you into making your project far more difficult than it needs to be. Without knowing the details, here's a basic outline: Close the water supply valve at the wall. ...

Cut a sheet of wood into the dimensions of your window. Screw in L brackets in the four corners of the wall where you want to put the wood. Then just like a picture frame you install four rotating pegs to hold the board in place while you watch the movie. Depending on your budget, you could also install magnets on the back of your board to hold it in place ...

Take some 1/4 inch plywood, and, with a circular saw, cut vertical slices in the back side ~3/16 inch deep, every half or quarter inch or so in the area where the bend is. This may give you enough flexibility to bend the plywood around the curve. Try it with some scrap wood first, and maybe use a gallon paint can to form the wood.

I would give your business to one of the "is good and stays dry" roofers who are not blatantly trying to fleece you. Now, the other two may be working from the assumption that if you bothered to call a roofer, you have leaks. But they strike me a lying scammers if they are selling you new plywood with no idea if the roof deck is rotten or solid. Plywood ...

Even on a good day, brad nails can curl on you. Through your fingers, if you aren't careful. However, if you look closely at the pointy end of a strip of nails, you'll see that they're cut at an angle on only two sides. (The other two sides are the ones adjacent to their neighbors in the strip.) Anyway, the nail is predisposed to curl in the direction of ...

First off be aware of a couple of important points. In the old days before there ever was electricity and power tools crafts persons could build amazing things out of wood with hand tools alone. Woodworking, similar to any other craft, takes patience and practice. Plywood material such as you are proposing to work with is a modern thing invented in the age ...

If you're not too attached to your current design, consider getting a pull-down projector screen (example). They hide away almost completely when not in use, and you can install it without permanently attaching anything to your window frames. They also have reflective properties that make your pictures look better than a normal painted-white surface would. ...

The plywood goes down so the groove is away from the wall, that way, after the row is finished, or at least when you decide to start the next row, a 2X4 can be placed across the joists at the edge of the next row and drive, with a sledgehammer, the second run into the first. The gap should be 1/8" between ends. The tongue and groove (T&G) of the sheets ...

3/4” OSB board is better than 5/8” gypsum board. Sound control is measured in STC ratings (sound transmission coefficient). Here’s a website that tests various materials: https://www.ecopacificinsulators.com/uploads/4/7/1/6/4716609/sound_transmission_stc_rating.pdf Gypsum board is not as good as OSB board. 1/2” OSB board equals 5/8” gypsum board. As ...

The usual approach is a couple coats of polyurethane varnish. I'd sand it a bit to clean it up and give it a coat on all exposed surfaces. Steel wool between coats. It'll be apparent when you've applied enough coats to seal the edge grain well enough to protect it. Reapply every couple years as needed. If you want the plywood to have a color, simply stain ...

Looking for "sanded" plywood and check the specification for the panel you are looking to purchase. This one is a 4x8x3/4 from Menards. https://www.menards.com/main/building-materials/panel-products/tile-backer-board/4-x-8-acx-sanded-plywood/1251420/p-1444425371729.htm

Cutting shallower (with the handle closer to the work) will encourage the saw to cut a straight line. Cutting steeper (with the handle up high) gives you more maneuverability. Start the cut being careful to keep the blade in line with the cut. As you cut deeper, lower the handle to about 30 degrees. The blade will want to keep cutting in the same straight ...

If you use 3/4" plywood and not a veneered MDF you could drill a small pilot hole for trim head screws. It will leave a hole about 3/16" in diameter that will need to be filled after the panels are stained/sealed. That is the best simple way to do it. Even simpler would be to use finish nails. They would leave a hole to fill of about 1/8". The lengths of ...

In order for a bookshelf to topple forwards, it is necessary to have some force applied to the structure. Typically, that force is gravity. Gravity will not usually push a bookshelf out of plumb, disregarding earthquake activity for the purposes of this discussion. Your floor must be level. If not, adjust the base of the bookshelf to keep the structure ...

Just add (nail, screw, and/or glue) additional framing material to the side face of the joist to provide more bearing area for the subfloor.

The problem you have here is you are trying to solve an aesthetics issue. You could tackle this 10 different ways but what can you make look good? This could be done with just plaster or some lightweight concrete blend (how they do a lot of stairs in europe). But can you make that look good? You can certainly have someone create a piece of wood for you ...

It's a mistake for the roofers to say that the plywood will definitely have to be replaced. However, they may be familiar with homes in your area, that were built around the same time. So they may have experience, that tells them that the decking will likely have to be replaced. Sometimes in situations like this, contractors will pad the estimate with the ...

They're required by 2012 IRC to use a fire retardant treated plywood on the roof within 4' of the UL assembly (the firewall that's between each unit). They can use OSB in the middle as it's much more cost effective than plywood.

You defiantly need to support the subfloor around the perimeter. Let's say this is your floor without plywood. You want to put plywood down, but the edge of the sheet has nothing under it for support. If you don't support the plywood, you'll end up with a "soft" spot around the perimeter. Stepping, or adding weight to this area will cause the ...

Fasten your first layer plywood subfloor as you normally should. The second (top) layer of plywood joints should not coincide with the joists and the second layer should not be fastened to the joists.

1/2" plywood is for temporary applications, exterior sheathing and used as gigantic shims. It does not belong as a floor or a roof; minimum 5/8" exterior grade. HardieBacker: What subfloor should HardieBacker board be installed over? The minimum subfloor specified is 5/8" exterior grade plywood or 23/32'' exterior grade OSB subflooring. HardieBacker ...

I've never used a Japanese-style saw, but have always found it easier to keep a long cut straight with the rigid blade of a tenon saw than with a carpenter's saw. Held at a fairly shallow angle, a tenon saw can make an indefinitely long cut in material up to about 12mm thick. Then finish with a jack plane with a very sharp blade set shallow.

Short answer: No If the tile was originally installed properly it goes under the toilet and the toilet flange sits on top of it. If the bathroom was re-tiled around the toilet in-place it may be possible to tear it out but then it should be re-tiled properly. You should be able to tell by looking at it if the tile goes under the toilet or not. If someone ...

Your current plywood is suitable for hardwood installation. I do not ever like to use 1/4 subfloor as it is brittle and when screwed sometimes doesn't lay flat. If I added to your subfloor I would at least put in 1/2 inch but like I said you don't need it with 16" OC. Note that a thicker sub might have benefits but at the same time you are adding weight ...
