OK, SO IT'S NOT A SCIENTIFIC TEST......SUE MEFirst Pic..... A load on top shelf( the point to most likely transfer a LOT of weight to the column).  Second Pic..... THE ALL IMPORTANT OVERLOAD TESTThird Pic....  The deflection of the column at the midpointFourth Pic..... Just bein' artsy fartsy  I still am amazed at structural stuff.  16lbs of iron supporting a good deal of weightI really want to thank William McCormick for my first inkling of the power of the flange.  And I want to thank a bunch of guys, y'all know who you are, for helping me flesh out the concept.  The power of steel under stress is a awesome thing.  I wouldn't have dreamed of building with such small members before.  THANKSAnd just so y'all don't think I'm a total blithering idiot  The service load will be concentrated at the bottom.  It's gonna be interesting to measure the deflection as the load increases.  It's seat of the pants Southern Engineering Attached Images"Any day above ground is a good day"http://www.farmersamm.com/

Reply:Good job, Samm!!!! And yes, it;s amazing what channel can do in bearing a load. I have one I made of 1 1/2"x .060" Square tube and about the same design. Of course I don't load it like you can yours, but it surprises me the amount of weight it will hold.                           MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw

Reply:Samm, in Post #3 isn't that the left kind of forkhoist?Glad to see it holding weight, I was confident it would. If you're worried about it sinking, measure the area of the footprint your tractor wheels sit on and then divide that into the tractor weight to see what the ground loading is and then have your rack supported by a similar load factor. Some trenchers and tracked machines can be around the 3lbs per sq inch and hence leave about the same impression as a person.As a practical example, I'm about 260lbs and I travel on about 60sq ins of sole. So roughly my ground loading is 260/60 = 4-1/3 lbs/sq in. This loading also explains why people wearing stiletto heels ruin vinyl flooring. Consider a 140lb lady on stilettos, steeping forward about half her weight will be transferred to the heel, (if we consider a narrow stiletto at 1/4sq in) then loading will be 70/.25  = 280lbs/sq in.So, sit your rack on tractor tyres, not stilettos!"One of the things we have to be thankful for is that we don't get as much government as we pay for."

Reply:This type of rack if designed correctly will hold a lot of weight. Looks to me like the design and fabrication will both withstand for some time. The differential loaded as it is at the front of the top shelf provves, not only that it is stable, but that a load at the bottom will keep it from falling in your face from the top being overloaded. Yes, I'm long winded, but I'm also jealous. I've been needing just such a contraption for the home front. Good job Farmersamm!!    Now you need to weld a couple of dogs on the back of the feet behind the rack and stand plate up against the uprights. That way your angle, pipe, channel and plate are all in one location.

Reply:I think it will work Samm.  I am a bit surprised that you didn't add the gussets under the horizontal shelves. I'm not saying that I think you need them, just that I figured you would probably do it.

Reply:It always seems to surprise me every time I go to my steel supplier and pick up some steel, just how heavy it is!But of course what I use most is pretty thick stuff like, 3/8" and 1/2"x 2 to 4 1/2" wide and 1/4"x2" square tube and some 1/2" to 1" round bar, so just a little bit of that stuff adds up to quite a bit of weight!I need to make me one of those racks, but I think I will wait until I get moved and settled into that new house with its big 40'x60' shop, then I can build it inside and keep the metal from rusting, cause as of right now, I would have to do as you have and leave it outside to the weather, and I hate working with new but rusty metal!Right now, I have a couple of cement blocks on the floor of the shop, and I have the guy's cut my stock down to 10' length's and store them in there.I usually don't buy much more than what I need "not enough room" and I have to haul it in the back of my short bed Ford, once I get that new shop together and finish my deck over trailer build, I will be able to leave the stock in its 20' sections and not have as many end drops laying around!------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Here's the trailer build, a waiting for me to get started on it again!I still need to put a 4' adjustable dove on its tail, build the upper frame, paint it and lay out the wood deck.Those are 16' 2"x8" treated you see on its top, and of course a bunch of angle, C channel  and box steel laying on top too!

Reply:farmersamm  if you get a (cheap) copy of welded steel structures from the Lincoln Foundation you'll have a better grasp of building welded steel stuff. Plus all other books they have (cheap) that are written by Omar Blodgett. This will save you or anyone else from spending time/money/material/consumables trying to reinventing the wheel. A ton of engineering knowledge based on over a hundred years of practical experience and lab test's is available to anyone who wants it. I'll add thet to get the most bang for your buck, every free standing iron rack I've ever built was able to be loaded from either side, that is a rack that loads only from the front may make use of less space, but makes much less use of the iron on hand. Farmers usually have more space than iron, I know I do. Racks that are inside and placed against a wall usually load from one side only out of neccessity. JTMcC.Just my take, but from looking at the pictures you could of saved considerable time and effort by running the horizontal that's welded between the uprights midway at the very top, one piece instead of two. And one diagonal running the full width instead of two to fit and weld. The diagonal would work just lovely clamped to the back side of the uprights. Plus I'd most definitly add a knee brace to every horizontal material carrying piece, as large as practical to reduce the deflection.Just my take from welding several hundred racks (close to a thousand in my younger days), some from stamped drawings and some from experience.JTMcC.

Reply:Sure, it's your time and money. If you want you can develope a number of home brew experiments (and cronicle them in detail on the net) to devise a handheld telephone device! And maybe do extensive backyard research on a working model of a pickup that has four wheel drive for those muddy conditions! I'm just trying to put the old, well worn tools in front of you that are used in this type of work. Wether you're interested or not is up to you.But keep in mind, there are people who read this stuff on the net and actually believe it. Plus there are people who work in the field that don't.As for "lugweld", if you have a problem with me, address me personaly like a grown man instead of making a bunch of little girl like nit picks towards me.

Reply:JTMcC, go check out some of Sam's other builds.  He's been at this a little while .... Some people just like to experiment, and Sam's one of them.  I haven't been welding too long myself, but I'm still in the "How can i do this?" stage, and I like figuring things out for myself, too.  I definitely see your point about the reading material - sometimes ya just need that little bit of extra help ..... (Thanks for the tip on that book, btw.)
Reply:I've said before that there are at LEAST two different welding universes. The AWS-WPS one and Samm's. I don't have time to learn everything. I live in Samm's universe and I'm glad he takes the time to post his projects, with pics, and how he got there. WithAllDueRespect: JTMcC has his insurance company looking over his shoulder, I don't. I will say; I know my limitations and it's why I'm taking classes. Without Samm's ramblings  and everyone's criticism, I'd know less.9-11-2001......We Will Never ForgetRetired desk jockey.

Reply:In samms way of doing things, isn't much different than the way they built things 100 years ago!Most of the engineering technology that is in books today has come from the more recent past, where everything is built to utilize the least, and that isn't always good!Take for example the school I went to, it was built back in 1891, it was a 4 story brick and stone structure that stood the test of time, it was used up until 1992 when they decided we needed a new school.The new school was built using the latest in materials and design that used the least and cost effective methods and was finished in 1994 and they tore the old one down, here we are 15 years later and they are already talking about how this new school is falling apart, and needs a major overhaul, and is going to cost a small fortune to make it better, if thats how the new methods of construction work, give me the old, seat of the pants, make it strong and use enough good material to make it last, anytime over the new!Here's another good example, an old iron bridge we have here, there where 2 of them here just outside of town, they where both built in between 1905 and 1910, they tore one down and replaced it with a new concrete one, the older of the 2 is still standing and is used every day after 100 years of use, while a couple of other bridges in town that where built in the 1980's, are in need of being replaced, or at least rebuilt already!#1.
