Sheet aluminum and pop rivets. Extra points for using old beer cans as the aluminum source, label side out, but flashing is a bit thicker than today's beer cans. Hairy (loaded with fiber reinforcement) Bondo. "Bondo Hair" is the actual label on the can. Some screws or pop-rivets might still be needed to help the bond to the plastic at the edges. Looks awful,...

Tightening the transparent plastic is mainly for cosmetic reasons. As long as the tape stays in place, the plastic will do its job of preventing air flow. If the kit is exposed to buffeting winds strong enough to snap the plastic sheet back and forth, it could tear or pull off the tape. So you want it to be as tight as possible. In general most people find ...

I've cut chair mats by laying them on a flat work surface. Then secure a metal straight edge along the cut line. (In my case I clamped a long piece of aluminum bar stock in place to the work surface with the mat in between). A utility knife with a sharp blade was then used to score a cut line along the straight edge. Chair mats are a relatively soft plastic ...

The hairdryer step is for two reasons: To prevent noise in drafty situations, and to improve visibility and aesthetics. If you can live without either of those, it'll work just fine. One possible solution to your pull-away problem would be to apply the double-stick tape to the outside face of the window trim (perpendicular to the wall surface).

Better plan: cut out the damaged drywall and install a low-voltage bracket and coax barrel wallplate Some cheap-arse folks do what you see here -- simply punch a hole in the drywall to run low-voltage cabling through. While this sort-of-works, it leads to ugly results like the ones you see here. It's much better to do the neat and tidy thing and install a ...

What you want is called a bulkhead fitting. This has a gasket to make a seal against the container, and threads to connect to whatever fittings you need. Some have outside threads on only one side, or you can get them with inside and outside threads on both sides, and they cone in all sorts of different sizes and materials. You can screw in a 6mm push-...

Plexiglas (poly (methyl methacrylate)) is strongly attacked by xylene, one of the solvents in the sealant you selected. I'd expect the sealant to soften the plexiglas and probably also whatever plastic the air conditioner is made of.

To answer your questions: "Why doesn't duct tape work for cables? Is it the fault of plasticizers? " - No -- it is more likely that exposure to air dries the glue, causing it to eventually lose its tack and become unstuck. This is also the reason that you're often left with sticky residue, as air was unable to penetrate to the underside of the glue. "Does ...

Gorilla glue makes a non-toxic PVC cement.

To smooth up the XActo saw cut (a truly excellent tool), you can often flame-polish most thermoplastics, provided you do so carefully. Flame-polished is smoother & shinier than sanded. Here's the general process: First, to determine whether this is a thermoplastic or a thermosetting plastic, expose one waste (past the projected cut) edge to high ...

If the clothes dryer (possibly Kenmore Elite) was included in the sale it may be the shelf unit that allows you to dry sneakers without them banging.

No, it's not safe to drill into something unidentified. White PVC is most commonly used for waste water (and vents, which are connected to the waste water lines but carry sewer gas to a vent the roof) and central vac. Schedule 20 is used for central vac and is much thinner than the Schedule 40 used for plumbing It's also possible it's a conduit run for ...

Most products you purchase will have the information on the label. If no information is provided you can look for a marking similar to the following that will help you identify the type of plastic it was made with. ABS does not have a symbol, but is often marked >ABS<. In your case, I'd look around the base of the hose reel you should be able to find it....

Replacing is probably most practical. But if you really want to fix it, you need something to support the weight. Tape and glue aren't going to do it. I would find a length of strong pipe (check the plumbing section at a home improvement store) that will fit nicely either inside the leg (if it is hollow) or over top of it. Make the pipe fill/cover as much ...

The surprising (to me) answer may be ABS cement. You probably won't find this in the hardware store glue isle, instead head over to plumbing: You'll want the smallest can possible (e.g. 4oz), and after use to seal it in a zipper lock bag and store in a cool dry location. The stuff goes bad in the can pretty fast. The ABS cement worked for me far better ...

Forget trying to glue it, repair it some other way. "McGyver" it. Like maybe buy a lock hasp of appropriate size and use the staple, which is the piece that the lock shackle would go through (see picture). Sorry I could not find a picture of just the staple. Screw the staple to the speaker body and the staple hole would rest in the base, aligned ...

I think if you use a couple coats of good primer and a finish coat of enamel paint, you should be fine. Just be sure to work it into the wood well. Two thin coats are always better than one thick coat. The cat door is gonna protect the cut edges quite a bit as well. Put a small bead of silicone caulk on the inside of the cat door bezel before you install it ...

Sandwich the workpiece between two pieces of wood, clamp it all together, clamp the whole assembly so that it can't go spinning off into oblivion, then drill through the whole thing. You'll also want to use really light pressure when drilling through the plastic, but don't go so slow that you melt the stuff. If you have some, you could use a step drill ...

Why not create a shelf-like support using two or three angle brackets to support the weight of the docking station? The vertical leg of the bracket could be screwed into the side of the desk, and the horizontal leg (in the down position) would carry the bulk of the weight. Then the hook and loop style hangers would only be holding it tight to the desk (...

You've got to pull the band toward you when you're at the edge of the chair and get some slack where the band goes around the frame. Then use a screwdriver to gently pry the band out of the slot on the frame. If it's an old band there's a chance it will break when you try to pry it out. If you're successful then do the other side. Installing them is just the ...

Glass shower enclosures are typically supported by the walls and specifically studs in the walls. Often they will be attached through the shower surface (tile, granite, etc.) if it's structurally sound. Glass is heavy. The biggest issue is typically with the door because it is hinged (suspended) on one side. Some of the weight of the door can be offset with ...

I have gone through many different versions of whiteboards; purchased and DIY. Quickly, they all become terrible and the ink is difficult to erase. I tried car wax to condition the plastic as well with little results. I ended up stumbling upon a fantastic solution: I cam across some pieces of glass with rounded edges that were used for a shelving project. ...

Some sort of 2 part epoxy should hold up pretty well. Araldite is a common brand in the UK. For best results, try to remove the old glue so the bond is to the plastic itself, scuff both surfaces with sandpaper, then clean with something like alcohol to ensure the best bond. Allow to dry before applying epoxy. It's important to use the specified proportions ...

After 30+ years in the plastics industry, my tried and true method is to take a scraping of the plastic piece and burn it, extinguish the flame and smell the smoke. Polyolefins will catch fire, smell like candles (a paraffin based plastic); PVC won't usually ignite, smells like chlorine and will burn your nose - BE CAREFUL; ABS has a sweet smell and burns ...

If the scratches are small, you can use toothpaste, which contains very fine abrasives, to polish them away. I have used this method for example on plastic eyewear (including my own prescription lenses) to good effect. It is cheap, small scale, and requires nothing in the way of special tools.This approach will also polish the edges of deep scratched making ...

I've used a similar process to restore hazed automotive headlights. 3M sells a kit that is used with a power drill and includes all the required materials. I've used this kit and was happy with the results. I'm not affiliated with 3M.

Ok, I'll keep this going and toss in my 2 cents worth. Dig a hole 6 inches deeper than you need. Add 6 inches of gravel. Pound it down with a fence post. Add more to bring you back to 6 inches. Repeat as necessary. Double wrap the bottom of the post with Grace ice and water barrier. This stuff sticks to wood like super glue. Finish the wrap a couple inches ...

I have been a fence contractor for 25 years. It is important to keep the soil away from the base of the post. Wood rot starts there because of moisture, microbes and fungus. Post rot does not start underground because there is no oxygen there or fuel. It is important to crown or slope the concrete above the grade to keep soil away and so water runs off and ...

Plastic models are made out of polystyrene. The cement that is used to glue model parts together melts the parts and forms a weld. It is not an adhesive and actually works much like PVC cement. Applied properly what you wind up with is a solid weld rather than a glued joint. Use sparingly.

the plastic will trap moisture in your sheetrock and can cause black mold some areas require hazmat teams for black mold removal, Ran into this a few years ago and it was quite expensive for the home owner.
