Lesson learned: Whenever there is wood, there is warp. It was very difficult to build a “perfect” handrail system upon a “very imperfect” deck structure. (The deck was perfect 10yrs ago). Compensation nearly everywhere. Anyway, trying to maintain parallelism, perpendicularity, straightness, and level was a serious pain >>>> One thing affected another, affected another, affected another, affected another,, ect. Not to mention the wind blowing the shielding gas.  Pretty much ruined my summer.
Reply:I can certainly appreciate all those challenges. I really dig the minimalist and unobstructed view design. Great work.
Reply:Looks great.  Good result in the end despite the headaches.Sooo, when are you comin' to my house to give me a hand with mine.  Attached Images
Reply:Geez.. at first glance I thought this was about a cheese slicer!Seriously,  Nice work!  As Jimmy_pop said, minimalist and unobstructed view design looks great!How did you arrange to maintain tension on the wires?  Is this still adjustable after installation?- MondoMember, AWSLincoln ProMIG 140Lincoln AC TombstoneCraftsman Lathe 12 x 24 c1935Atlas MFC Horizontal MillCraftsman Commercial Lathe 12 x 36 c1970- - - I'll just keep on keepin' on.
Reply:I would have built them out of rectangular frame panels with the cables tensioned within the frame.  Next mount the frames to the posts.MillerMatic 252, HTP 221 w/cooler, Hypertherm PM45, Lincoln IdealArc 250 AC/DC"I'd like to believe as many true things and as few false things as possible"
Reply:I did'nt reply at first cause I thought you were complaining it came out crooked, and it looked great to me! LOL, great job! I hate being bi-polar it's awsomeMy Heroes Have Always Been Cowboys
Reply:Question to the rail guys.. Does this meet code? I thought a rail system couldn't be "climbable", and cable systems like this fell under that heading especially since the deck looks to be quite a bit off the ground.Not knocking the railing, I think it looks great. I've always liked the look of these, just thought with the newer codes they were no longer allowed unless the deck was low enough not to need rails..No government ever voluntarily reduces itself in size.

Reply:Hesitated a few times before replying to this thread. Any way here goes as Im seeing more and more crap posted here by  "Professionals" and I tend to ignore it and not comment as Im not here to put people down , fight or look good , rather to learn.As to compliancy I am totally ignorant of US Codes , but its not even close for Australia.The above job is a fair result for a Home Handyman working on his own property . But you mentioned in your earlier thread you had been hired to do this , for a Professional its simply not good enough.Wire balustrading can be trickier than it looks .... if your approach is wrong and your product knowledge incomplete.Look, none of us come out of our Mothers womb gun Tradesmen, i look back on a few jobs I did 20, 30 years ago and cringe in the memory.What is  wrong with the job ?And YES I accept it is only in my opinion .Site Mig welded and cleaned up.Wired before powder Coating , and if your Electrostaticly painting it on site , even worse.Wrong sectional sized postsWrong orientation of posts.Double posted cornersWrong orientation of base platesInnapropriate tensioning method.Seems to be coach bolted downWire centres incorrect (?? US Codes, I could be wrong)Post centres too far apart (?? seems so from photo I could be wrong)Wrong fabrication approach.And all in all not a finish or effect  I would excect from a Pro.There are other things also .I genuinely dont want to come across as a know all and P#ick .But you got my honest opinion.Brett Thompson.A good guess is better than a bad measurement
Reply:I genuinely dont want to come across as a know all and P#ick .But you got my honest opinion.Brett Thompson.[/QUOTE]Brett, thanks for the input. I calculated horizontal tension (with criteria of Alum, 1/8 walls, 1” x 2”) using FEA. The swage terminals are 3/8-24 thread (hand tightened only). Note- it doesn’t take much torque to keep the cables straight. No issues with structural integrity and/or dimensional stability (from cable tension). Regarding mig welding on-site. No choice for mitered corners, absolutely no alternative. See pics. I welded base plates in “the shop” as shown. Sometimes construction arrangements dictate the welding outside on-site. Once corners were welded, the entire system became rigid. Much more to this project, reinforcements hidden inside each aluminum post.... Also – Project direction indicated the following:1). Posts shall have base plates mounted to deck boards (absolutely no posts shall be fastened/mounted to fascia boards, nor shall posts pass through floor. No exceptions.2). Cables shall terminate at each corner, no routing around/through corners.

Reply:I think it looks great as well.  I like the hidden steel supports.  How did you drill the holes on the corner posts and slide the cables through with the steel inside the Aluminum?TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum
Reply:I see so much more now , I assumed a lot .....Whats the old saying about assuming? I agree with your structural approach with those twin rods used. ( being mild steel Im not real comfortable with though) and if you used the mounting detail post that would be strong as.Still 4 points worry me .The finish ? How is that going to be done , surely not a hand painted approach??Double Posting corners? , a single corner post is a far more elegant result especially using Button Terminal Swages. as in http://www.aaametalsuppliers.com/pro...nals_swage.htmThe male Swage Terminals with nuts or Domes on them ? far better to use a Hex Head Tensioner as in http://www.aaametalsuppliers.com/pro...tensioners.htmI have done hundreds of these (well a lot of them maybe in 3 figures  ) and most of them on timber and have never site welded miter or installed them in mill finish . I doubt if I ever will . To be honest with you  I couldnt put my name to it, I just cant see a way of getting a decent finish. Hey maybe Im missing something that could be useful.... live and learn eh??Just a minor point on the second diagram in your post , having the "Springing point" projected past the top post will lead to an inconsistant gap between top rail at upper most wire.I agree that Fascia is an ordinary way of doing a balustrade.I am also glad to see (as so many seem to try to) that you didnt run the wires around a corner. Apart from being out of code over here , you cant tighten them enough.We actually have to tighten our wires quite a lot to get our required tension , ( our wire code is quite specific as to that , surprised yours isnt )We would have to run 3.2mm wire (I think thats what you used?) at 80mm c/c with a max 1500 between posts and still have to get 1330 on a strain indicactor or 5mm deflection with a 2kg weight ... not much... Ive attach part of our code  a smal part LOL Interested in your responses Regards Brett Thompson Attached ImagesLast edited by Brett; 08-23-2012 at 06:36 AM.A good guess is better than a bad measurement

Reply:The cable tension and deflection guidelines are actually a good idea. I've see a few cable jobs where there wasn't nearly enough tension. Mr.Joshua, I disagree about "must be field welded", it's not absolutly necessary, it's just easier. I also disagree about fascia mounting and cables going around corners, there's nothing wrong with either practice. It seems who ever gave you "project directions" doesn't know what he's talking about. I guess it must have been a "look" thing, but, as you found out, putting all those separate sections of cable in tension will warp everything.Ian TannerKawasaki KX450 and many other fine tools

Reply:Looks good!Follow code if you want to be like everyone else. Personally I like to be different, just use common sense and make it safe.And those communities where they tell you what color your house can be, what kind of roof you can use, how long your grass has to be and whatnot, LMAO!Interesting question dsw. For here, rails just need to meet the 4" sphere rule, unless it is a pool enclosure. Then, IIRC, there can be nothing climbable within 54" of the top of the fence, so they don't work for that.

Reply:I was going to put this in a PM to MR_JOSHUA but I'll put it in the public forum of this Board.MR_JOSHUA posted a thread about a job he did and how it wasn’t as easy as first thought .I replied and made some comments referencing that I didn't agree with his approach and methodology.Did he get his frilly knickers all bunched up and come back with a "Internet warrior" tirade?No.He reposted more information showing the reasons and hidden details of why and how.In a calm, professional and ADULT manner.Should be more people on this board like that.I doubt if MR_JOSHUA and I will ever 100% on all details , what two Tradesmen do? But we will be able to discuss our opinions like adults and Men. How some posters here can twist that conversation into the value of a political party or even disparage a whole country 1000's of miles away from the job really does just reflect on their value as men. Its interesting to note the most vitriolic responses have come from those of the least knowledge and experience.I guess that’s just the way it goes with the anonymity of the Internet. The weak of character and the ignorant of the facts can say what they like without consequences, as opposed to saying it face to face in real life.Brett ThompsonLast edited by Brett; 08-23-2012 at 08:18 PM.A good guess is better than a bad measurement

Reply:MR JOSHUA,  I think your hand rail turned out fantastic! But it doesnt matter if I or some guy from Austrailia, or the county building inspector like it.           How does your customer like it? That is the bottom line and in the end, its the only thing that mattersLast edited by Gump; 08-24-2012 at 08:15 AM.Safety 3rdGump
