Thanks for the helpful advice on scraping vs. sanding my son's ash bed. I sanded to 220
and the first coat of finish (Tried & True Varnish Oil) is already silky. I don't want to put oil finish on the poplar slats since they contact the mattress. Would it be better to shellac them to reduce movement due to humidity changes or leave them unfinished? Thanks. -- Bob |

Why finish them? Wood movement isn't necessarily a bad thing. You only need
to control it where it wood is joined and movement of the wood can cause problems with some sort of joinery or attachement. Attach the bed slats with a screw through the middle of the slat to your ledger strip and any movement will be an expansion of the wood away from the screw. Another thought - use plywood slats instead of hardwood. No wood movement and much stronger across it's length than hardwood. "Bob N" wrote in message om...

Doug,
Disagree with your comment on plywood over solid wood. In wood of same dimensions, plywood is much stronger than typical wood (especially something like poplar). You don't have the wood defects, splits, checks, etc than can weaken solid wood. Since plywood is laminated veneers of solid wood with the laminations running at 90 degree angles to each others, it's resistance to breakage for something like a bed slat is much greater than a typical piece of poplar.

I gotta just Gotta back Doug on this one,
By the way bed slats should be made out of Maple poplar just wount cut it strength wise It is also a good idea to pick out a board that has a bow to it and use them convex side up also I've never seen a bed slat finished yet Sweet dreams George "Gary" wrote in message . ..

Thanks, guys. I was worried about poplar's strength but the lumber dealer said it would
be fine and it was about half the price of the ash. I agree that it should be fine because 1) there are 14 slats, each 3 1/2" wide and 3/4" thick for a full-size bed; and 2) the construction of the mattress should always spread pressure over several slats and 3) no one in the family is "super-sized" enough to sue a fast-food chain. I'm going to leave them unfinished. I put the first coat of varnish on the bed yesterday, it took on a nice honey color over night. Of course, last night I was reading Krenov (Fine Art of Cabinetmaking) saying that he would never put such an ugly "wet yellow" finish on beautiful ash. Well, too bad. He doesn't use run of the mill slab-cut boards either... |

Doug,
At last a real conversation about wood and woodworking in here! Sorry but the trolls in the newsgroup are really starting to bug me. I'm almost embarassed to open this group up somedays. I bow to most of your arguements on strengths and stabilities. The whole thing is really relative to what you're comparing. Oak versus poplar versus plywoods versus pine? All sorts of differing variables in the equation as to the strengths and weaknesses of each. One of the weaknesses you get in solid woods is the fact you pointed out that all the wood fibers run parallel to each other. This makes it susceptible to shearing forces. Most pieces of hardwood don't break across the fibers, they split at some point along the fibers. All depends on how you use the wood. But as to our poor posters original question (from which I've digressed) - I wouldn't waste time finishing or worrying about wood movement. Just make sure you have enough strength in whatever you use to withstand whatever weight you'll have bouncing on your bed. For what it's worth, I've just used old A/C plywood scrap for bed slats on my own bed frame. And Doug, appreciate the intelligent wood discourse. And you're right - I do need a new lumber supplier - mine just burned down last week! Gary "Doug Miller" wrote in message .com...

Bob: Select your slats for as near to quartersawn as you can get. Depending on the width of the bed, you may want to use 5/4 in preference to 3/4 stock. If you have ash left from the bed project, I'd use that in preference to the poplar. If the piece has a natural bow in it, turn it up. When I make beds I seal the slats with shellac. Shellac will not interact with the dyes in the bed fittings, unlike inadequately cured lacquer, varnishes, etc. By sanding and sealing the slats you will be able to adjust them with the box spring in place without abrading the covering and when you take the bed apart for a good cleaning, you will be able to wipe down the slats more easily. Do not use ply for slats. Those who would argue that it is stronger because it is laminated are ignoring the fact that the laminations will be at ninety degrees to the proper orientation with regards to strength. The phenolic resins used in ply lamination are not as shock resistant as the natural lignin in solid stock. Some beds need more shock resistance than others. Regards, Tom Thomas J.

Ah, for the good old days when we used to be horny and awake at the same time. And FWIW I agree completely with the solid wood camp on this one. No question about it. Plywood would make a crappy bed slat. I expect it would delaminate and break in very short order. We (the furniture distributor I work for) actually sell plywood slats for some of our beds, come to think of it, but they have a support running up the middle with feet in strategic places to cut the span of the plywood in half. -- Michael McIntyre ---- Silvan Linux fanatic, and certified Geek; registered Linux user #243621 http://www.geocities.com/Paris/Rue/5407/ |

I've never seen a bed with as few as 4 slats. Six, minimum, and that's with a foundation. For a mattress directly on the slats, Bob's number and spacing sound just about right. Some people (and much furniture) dictate that a foundation be used in order to bring the mattress to the proper height. I consider a foundation to be a complete waste; it takes up perfectly good storage space. Kevin |

Silvan, great story. I don't anticipate such problems with this bed. I will use screws
to fasten three of the slats into the ledger boards on the rails to prevent rail-spread. The rails themselves are 5 1/2" wide by 1 1/4" thick, fastened with that hook-type hardware which is mortised into the ends and attached with three screws per plate (bought from local Woodcraft store). I have a little concern that the top of the mortise is only 1/4" below the top of the rail - if that should ever rip out, I'll substitute wider boards for the rails to allow more wood above the hardware. -- Bob |

pixelated: When building the bed rail piece to hold the slats, notch it 1/4" deep or so to hold the slats. Wouldn't tacking on small stop pieces be safer than notching structural members, Charlie?

There are 14 slats because I didn't buy a boxspring, thereby saving nearly $200 and
freeing up space under the bed for rolling drawer units that I'll make later. All the slats are clear wood. I think it will be strong enough. As to weight, I decided a couple of years ago that I don't want to watch what I eat, so I run 20-30 miles per week all year and paddle my sea kayak (hard, long and fast) every day in the warm weather. Dropped 25 lbs. in 6 months and am also nearly at college weight. |
