[Carpentry] How to fix particleboard?It's a speaker and while it has wood screws over time the holes got a little larger so now it no longer holds at all.. I was wondering what's the best way to fix this? Or at least not have a decent size tweeter falling out each time you move it. |

[Carpentry] Re: How to fix particleboard?Wood Glue & Toothpicks to fill in the stripped out screw holes.
Alternatively, (If it's a Round speaker) Rotate the speaker and drill new pilot holes. |

I prefer wooden matchsticks and glue because they are not as hard as toothpicks. |

Home Depot has a product for fixing stripped screw holes. Basically some perforated shims that grip the hole and the screw. They work really well and hold much, much better than toothpicks + glue (I am using them for a door hinge where everything else failed). |

Inquiring mind here, how did the particleboard deteriorate in the first place? I hope this speaker isn't going above people's heads after you fix it!! |

Often speaker builders/re-builders use T-nuts and bolts, rather than screws, it allows you to tighten the speaker more, and more evenly, than screws. Also, it's easier to service repeatedly, if necessary.
I've got a great old set of Heil AMT3's that I've done that to, along with other cabinet and crossover modifications. |

Lots of ways to fix it. Wood epoxy (Bondo), fender washer, larger screw, threaded wood insert, or even an anchor. You could take some saw dust and mix it with wood glue to make a filler as well. You could drill it to the closest wooden dowel size then glue and insert a small piece of wood dowel into the hole. |

Being particle board and considering the little room to work with, you'll probably have to rotate the speaker and make new holes. Trying to use inserts, washers, glue etc, probably won't leave you with anything you can tighten really well. Usually, once particle board is compromised, it's a waste of time to try and fix it.

If you're worried about the integrity of the area a wood hardener, Strong-tie, or even a coat of wood glue can be applied. There are tons of ways to restore particle board to like new condition if someone wants to do so. |

Being moved 2 days a week on and off speaker stands for almost two years.. and being carted and taken to gigs.. I need to get some new stands because at least two are stripped out now. |

Too many people to reply to here but I can't rotate the speaker because it's a tweeter so it's still going to be the same.. here is the speaker and how it looks.. I was going to take a picture of it but the battery on my phone was too low to take a picture.. not a lot of room to work with and more so at the top inner part of the speaker. » www.musiciansfriend.com/ ··· -cabinet*edit wow did not know a single speaker is 61 lbs feels lighter |

In addition to the glues and potions mentioned above, you might want to invest in one of these speaker driver mounting kits so it doesn't come apart on you again! » www.parts-express.com/ca ··· kits/315You can probably source these parts at a decent local hardware store! |

said by Subaru:First thing I thought about were T-nuts but hopefully they are small enough Home Depot's site shows T-nuts down to a 4MM bolt size, at 0.598" diameter. I think I used 10-32 size in my speakers, which is pretty close to 5MM. I got mine from Parts Express when I was ordering crossover parts, » www.parts-express.com/ca ··· nuts/313 |

I just have to look at the speaker again I assume with T-nuts you can hammer it down or use the screw to compress and bite into the wood?
I don't know if the wood is wide enough for those holes and the T-nuts |

the best way to fix particleboard is to replace it with plywood. particleboard was never meant for rough usage, nor damp environments, if it gets wet, it falls apart!. make a new cabinet out of some nice thick plywood!. |

to Tursiops_G
That won't work well in particle board. The screw hole will be too close to the edge so there won't be enough support for that fix. T nuts might work if it's not too far gone. The best thing is to rotate the speaker. |

Unless it's a cheap ass speaker they also use something better than particle board. |

If you are handy with a router and a flush cut it that's an easy fix. Cut a piece of wood that the outside size of the horn. Install the cutout inside the cabinet, rough cut with a jig saw, and use the flush bit to trim it out. Then use some 1/4 to 1/2 inch longer screws to secure it. I would make the replacement out of MDF. |

If you use a hammer it may do further damage. Use a screw and washer to compress it. Be careful if you use a drill. |

It's an inexpensive PA speaker, eventually it will fall apart when it's moved around alot, especially if it's made of particleboard! What can you expect? Unfortunately the HF horn being rectangular, it cannot be rotated, so you're having to reconstruct the front face of the loudspeaker enclosure for new screw holes. You might want to see if you can drill some new holes in the horn to support it. No harm done if you stay out of the flare of the horn. If you're putting in new t-nuts, better make sure you have the right diameter hole for them, and the teeth on the t-nut have something to bite into (hardened glue doesn't work well). Not sure if replacing the entire front face of the cabinet with plywood is possible, usually these cheap cabinets are held together with a lot of staples and glue, and would be difficult to take apart without destroying it!
Any future upgrades, be sure to buy a speaker that is designed to be moved around a lot and uses plywood construction. The really good stuff will be made with 13 ply Baltic Birch. You get what you pay for. |

Funny most people complain about the weight of it.. I would of never guessed it being 61 lbs but more like 45.
I will most likely be taking the speaker home this weekend so I will grab the pictures. |
