It’s usually 6-inches x 8-inches and is 83 percent defect-free on its best side. id say the 2 1x4's will be stronger. If span matters use 14 feet "Simple approximation" calculation is fine. When you rip plywood into strips (say 1*4 for an L-girder) you get a strrip with half the grain running the wrong way. The 1x4 still offers close to the same strength in the 4" dimension. I'm going to need about 17 of them so the price difference is going to be about $9 (not a lot) but the shelf openings will be a smaller as the 2x4 will hang down lower. Now screw in the screws and allow the screw to pull itself into the other wood. The screws represent stress concentrations that initiate failure at those points. respected, when they are defended by an adequate power. Head-bore size refers to the diameter of the screw head. you have to chase the squirrels out of it before you can cut it. A 4X6 in many cases is a large chunk of today's trees. Wood does weird and wonderful (NOT!) The larger 2x boards (2x8, 2x10, etc.) One way to add strength to a framed wall is to make up laminated beams and headers. Stand the 2x4 up, and its cross sectional area is L times the width of the beam. Not Phillips, not flat bladed screws. Wood, as an element is very weak compared to other elements such as steel, zinc, iron (screw materials). That means a 2x10 is actually 1 1/2 inch in … Engineer Jeff NS Nut Visit my layout at: http://www.thebinks.com/trains/. 4 years ago. I'd also consider using a metal bed frame with the legs removed on top, rather than plywood (as long as you're using a box spring). The larger 2x boards (2x8, 2x10, etc.) These depend on various factors like the type of wood used and the number and types of defects, if any. Both were stud grade, but one was Douglas fir, and the other was spruce. If you look at the grain the 2x6's are almost always 1/4 sawed. So, that's (10) screws to secure each corner leg benchwork top, plus; a couple screws to make the L-shaped legs. A strip of plywood has only half the strength of a same sized piece of dimension lumber (plain pine). If you lay a 2x4 down, the cross-sectiontal area is the length of the beam, L, times the thickness of the beam. Hole is finished. The layouts I have built in recent years all had to be movable, light weight constructions were a must. I'd suggest the 1x4s. The grain in each layer of plywood runs at 90 degrees to the grain in the adjacent layers. This is for the material engineers out there... Say we take two 1x4 boards and bond them together with screws every, say, 4 inches on alternating sides. My website : wnbranch.com. All of my layout benchwork (open grid style) is 1"X4" pine, although I did use 2"X4"/2"X6"/2"X8" for the supporting  structure (mysteriously "left-over" after building my house ). A built up section is less prone to this. Of course, if just screwed and used in the wrong place, the screws will corrode. You should carefully check the wood grade before you take one … In my area, for the past 25-years or more, it has been typical to use 2x6 studs for exterior walls because of the All the "lumber" I get at our local home improvement store, cut to size on a CNC diamond saw with less than 1/50 of an inch tolerance. For most model railroads, even 1x4 lumber is overkill. Irving produces Appearance grade 2x3, 2x4, 2x6 and 2x8 in both Stud Grade and Dimensional Random Length (10Ft - 16 FT). A strip of plywood has only half the strength of a same sized piece of dimension lumber (plain pine). I get that it will not have the strength of other larger pieces, and deflection will be unacceptable. Thinking back, I used them because weight was not a problem, they were readily available, and made an extremely solid structure. J.D. Not sure the current stuff is worth doing that. i don't know if they still have the good stuff or if it is available at all locations but if they have a store near you it would be worth checking out. Note the layout is in a spare room on the second floor of my house. 1" x 4" wood has always provided more than adequate strength, and; will the basis for at least the perimeter benchwork and legs for the CR&T, as well as some of the cross-section supports.

"Premium" refers to the clean appearance of the board but doesn't verify the strength or physical quality. If you lay a 2x4 down, the cross-sectiontal area is the length of the beam, L, times the thickness of the beam. I tend to overkill, making certain that my 225 lbs could be supported if/when I crawl over the layout. The truth is, a 2x4 may warp, bow, or even twist as it dries out. Hardwood grades are: FAS (First and Second) is the highest grade of hardwood lumber. Rectangular steel tubing provides great strength-to-weight ratios, which means that less steel by weight is required to accomplish the job. 2 NonDense No. It is much stronger in one direction than in others. Replace the screws with glue that is stronger than the wood, and the difference disappears. Also you do not want to make holes on the long piece of wood. That's just 1.5" for dimensional lumber. This is 9 1/2' x 7'. Hardwood is graded by the National Hardwood Lumber Association. Wood is not a homogeneous material. An idea some years back in MR suggested a compromise,  If one has access to a table saw, get straight 2 X 4s, and with a couple cuts, end up with an 8' L girder and an 8' long 1 X 3 for crossmembers from each length without the work of screwing or nailing two pieces of 1 X  lumber together to make the girders. 1. share. Favorite Answer. I used 1x4 for my brackets and my L girders, but elected for the 1x2 stingers in the yard and 1x3 and 1x4 stringers in the mountain areas. when i was buying 1x4 and 1x3 lumber a few years ago, i found the best quality at lowes. It’s usually 6-inches x 8-inches and is 83 percent defect-free on its best side. I paid extra for select pine for the layout, but you have to be picky. Some folks have ripped 2x4s down to 1x4s because of the cost but you have to have a saw which will support this. When wood is milled from a rough to a smooth surface, it … Still have questions? So, if you bond two 1x4's with stronger elements, the resulting board will be stronger than a single 2x4. Shank-hole size refers to the diameter of the smooth part of the screw above the threads. Would we survive if the temperature became 1000 degrees Fahrenheit for 1 minute? If you're having fun, you're doing it the right way. If you glue and nail them that will be stronger than just nailing them together. Two 1x4s would not likely have defects in the same places where as a 2x4 is likely to be weak through the thickness of the whole board. Thanks!

The shelving beneath much of the layout is covered with 3/8" sheathing plywood, and provides plenty of storage for train "stuff" and all sorts of heavy household items. Living in southeast Texas, formerly modeling the "postwar" Santa Fe and Illinois Central. It seems that 2x4 purlins are better on a small cabin with a 12/12 pitch due to costs, ease of installation, holding power for screws. Saves screws and nails, and the work involved in keeping the edges ligned up while joining the pieces. 2x4 3x4 4x4: Dense Select Structural Select Structural Non Dense Select Struc No. Wood strength, including the relationship between grain direction and strength, specific gravity as an indication of wood strength, and additional ways to measure wood strength. structural capacity of 2x4 vs 2x6 from a structural engineer: The cross sectional area of 2x4 @ 16 and 2x6 @ 24 is almost identical. A nation, Assuming the grain patterns were similar and the outside dimensions are the same, the solid piece would be stronger. With respect to conventional framing (16 inches or 19.2 inches on center joist spacing), I-joists are 50 percent stiffer than solid sawn lumber. Is there any structural difference between a wall framed with 2x4s 16 inches on-center and a wall with 2x6s 24 inches on-center? 1650 Years ago, when  I could get decent pine 2x4 studs I used to rip them into 1x4s. If your benchwork will not be mobile, I would skip the 45 degree leg bracing that's seen on so many layouts and add a shelf about 18 inches off the floor as leg bracing. I used 1x4 for my brackets and my L girders, but elected for the 1x2 stingers in the yard and 1x3 and 1x4 stringers in … I was concerned that the tensile strength of a single 4x4 would not be as strong as 2 2x4's. I work in a small lumber mill and would never use a 4x6 on a long span because the knots are all in the same location so there is less strength there also. Stress will be concentrated at the screws and not evenly distributed. 2 Dense No. Soaks up paint like a sponge. Drill with a twist drill bit the same size as the screw(if not slightly larger) a hole or two -depending on the number of screws you plan to use .

Someone suggested getting a radial arm saw or a table saw to help with bench work. Where the 1x4 is much lighter and easier to work with when it comes to cutting. So, if you bond two 1x4's with stronger elements, the resulting board will be stronger than a single 2x4 on another note, i would avise anyone starting a large sized model railroad to invest in a radial arm or table saw. The difference is that mine are steel studs. That means a 2 x 4 board is actually 1-1/2 inches by 3-1/2 inches. If span matters use 14 feet "Simple approximation" calculation is fine. How far can a 2x4 span? Lumber is graded based on the quality and appearance of the wood. id say the 2 1x4's will be stronger. neutral.
