Handrail/Guardrail Project

admin

This is a handrail/guardrail I just completed.  This thing turned out to be almost 1200 linear feet.  The skate boarders could not wait for me to finish. Attached Images
Reply:Sorry I told a fish tale.  It was almost 600 linear feet not 1200.
Reply:Nice work, 600 or 1200 it still looks like a lot of pieces to me.If you don't want to stand behind our Troops, feel free to stand in front of them.
Reply:Wow, that's a lot of guard. Must be a minimum/maximum grade for wheel chairs or something?? Long ramp. Lot of ziggin and zaggin.
Reply:2 questions.... how did you mount those posts?and HOw in the heck do you figure the angle to built the panels at?  I build a lot of fencing and when it comes to a slope I either step it down (ugly) or I build it on site (Pain In The Arse)  I have tried angle finders and what not but when ever I build the panel it seems to be off a little bit when I install it.Looks awesome by the way!

Reply:Nice rail.  I am impressed.  Looks like you did some onsite work.  Is it painted?  What type welding regulations do you deal with in California?Yeah, I would agree with Scott.  Take the math out.  I use a large bevel square.  On steps.  I also use a digital protractor.  I have found the key being, measure across all of the steps in a run.Use a couple of strings the length of the run.  One string would follow the pitch the other would be level.  Get the average rise/run and make a jig, then build away.I guess a transit would work, I have never used one however. With math, You really have to figure how many digits would be significant for a given distance.  Then there become the tanslation from decimal to fractions.  Over a long pitched run errors are magnified.  e.g off 1/8" per foot for 100 feet adds up.Also, with steps Math does not consider imperfections in steps construction.
Reply:I did build the rail on site.  I did not really use math for this one.  It was pretty easy really.  The uprights are cored into the concrete 6" at 6' on center.  From there I just marked each picket at 4" on center. If it were off by a 1/4" it isn't visible on a rail this size and is still within code because I have 1 1/2 to play with.  Here I went by ADA Ubc 1997 addopted by California.  The angle was easy also because I fab on.
Reply:Yes it is painted with red oxide primer and then brown to match the library exterior.
Reply:Looks very good.  Man I hate to core drill even though most of the time people never think far enough ahead so that you can use embed plates.   So much nicer to walk up and weld them down instead of running the drill.Lots of toys.
Reply:Nice work LomitaWelder,Certainly looks strong!A good guess is better than a bad measurement
