Should I tilt my DIY self-standing bookshelf backwards to prevent it falling down?

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" ...

A pair of screen door turnbuckles would work well. Mount them from below with stout screws piloted into the wooden rails, one from the headboard and one from the footboard at 45° angles. Start with ...

Ikea bookshelf is wobbly after assembly. How can I stabilize it?

That back panel is not decorative, it is a vital part of the structural integrity of the whole cabinet. Have you actually nailed it in? It is fiddly to do so, but it is what is supposed to stop the ...

Should I tilt my DIY self-standing bookshelf backwards to prevent it falling down?

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), ...

For a slight bend (warp) like that you can try setting the board on blocks at its ends and weighting the middle. Overcompensate somewhat (weight to the point that it bends slightly the other way. Heat ...

Should I tilt my DIY self-standing bookshelf backwards to prevent it falling down?

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 ...

Ikea bookshelf is wobbly after assembly. How can I stabilize it?

It looks like you may have damaged the side panel here: That may make it difficult to tighten the side panel to the bottom shelf and leave the whole thing a little wobbly. If you're very careful, you ...

How to put 5/8" oak dowels into holes which are just barely the right size?

Some 1/2" drills will allow the chuck to open to 5/8". If you can fit a dowel in the chuck, clamp it in the chuck, touch it to a file while the drill is running. Use the drill as a low tech lathe. ...

You need to add diagonal bracing or struts as shown in the pic. Without a dissertation about the laws of physics that apply, you simply need to use the strength of the triangle. Even 1 inch square ...

Changing loft bed's beam to diagonal braces?

I'm really concerned about the stability/safety of what you're proposing. The diagonals seem under-sized to me but even with heavier diagonals I don't think the bed verticals would hold up. A 12 year ...

Structurally dubious on the whole, but the back sheet of plywood is probably doing a large part of holding it together, evidently adequately. I do see top brackets to keep it from tipping over. I ...

The lateral support on your bed mostly comes from the two connections at the top creating what is called a moment connection (think of lifting a long stick with both hands). The middle members do ...

How to fix this cupboard knob back?

I would use a dowel or 4 maybe 5 matchsticks glued into that hole. Once dry, drill a pilot hole and then refit using the existing screw.

How to put 5/8" oak dowels into holes which are just barely the right size?

Your best bet is to sand the ends of the dowels. A belt sander or disk sander however would not be the way to sand them. There would be way too big of chance of taking off too much or creating flat ...

Should I tilt my DIY self-standing bookshelf backwards to prevent it falling down?

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, ...

Nontrivial gaps are probably opening between the steel and the tabletop when you push horizontally. Insufficient stiffness of the steel ear plates is probably the root cause. The torsional stiffness ...
