I'd have to guess about the shelving. I think plywood by itself will always sag. You'd need some solid wood to get stability. |

They may sag, and I would provide a strongback along the front
edege......You will be amazed how much this helps with rigidity. Strongback like a 1x2 or 1x3..... I also dado the shelves and glue into the sides and make sure to cleat or nail the back. Glue all members..... jloomis "Jeff D." wrote in message ... I'm building a wall of storage shelving for my 45 record collection (appx. 20,000).

There are many different types of 3/4" ply, so there is no one 'correct' answer to your question. Personally, I'd not expect a 4' span to support that much weight, over a longer term. Eventually it *will* sag. |

![]() "Jeff D." wrote in message ... Not an expert on load tables but from what I can understand 3/4" at 4ft between supports would only be good for about 30lbs ?? Yeah, that "sounds" about right. With a 2' span, it would take 4 times the load to have the same deflection. That's likely the way to go. ** Posted from http://www.teranews.com ** |

Maybe the OP can put support the shelves one foot in from each end, with two feet between supports. Otherwise a little piece of angle iron bolted to the bottom of each shelf will stiffen it. |

They will sag with time. BUT if you finish both sides equally, then you can
turn them over now and then. s "Jeff D." wrote in message ... I'm building a wall of storage shelving for my 45 record collection (appx. 20,000).

![]() "Jeff D." wrote in message ... Not an expert on load tables but from what I can understand 3/4" at 4ft between supports would only be good for about 30lbs ?? I have a work bench made with 3/4" plywood doubled over and supported by metal legs five feet apart. On top of that bench I have two machine presses that weight about 50-60 lbs each and using them creates a hell of a lot of additional downward pressure. It's been going fine for thirty years with zero problems. |

Thanks for the suggestions, the sagulator is a great resource. Looks like
3/4 plywood with 2" edging front and back will work nicely. I checked into steel shelving but the cost (discounting my labor) was higher and couldn't find anything flexible enough to fit the space I'm using. "ransley" wrote in message ...

Consider some of the heavy duty shelving at Costco or Sam;s Club. The product looks good, and will easily hold the weight you anticipate. Other sources for that kind of shelving are salvage from store remodelings, often seen on Craigslist or classifieds. Makes sense if your talking storage and not furniture. Joe |

![]() Same with the Vinyl LPs. I haven't done it yet, but I think I'm going to just toss them now. Toss them??? As in garbage?? Sell em, donate to your church garage sale, Goodwill, anything. |

I doubt they have any value. They've all been played a lot. The 45s lack the original sleeves. Despite the condition, I was able to clean up the recordings I made, sometimes quite well. |
