(newbie) materials to build a sliding "inverted-L" stand / pole

Hi folks!Just discovered this fantastic website! I have this very cool idea for a 'ible I am working on and cannot wait to put it on the site. For now and as a first step (sorry, I am a newbie!), I am simply trying to build a simple stand with the following "inverted L" shape:- - - - - - - - - - - - - -||||(floor)Think of tje coat hanger in the picture below, only sturdier and with a single vertical pole (and without the wheels/mesh at the bottom). Also, the vertical pole does not need to be telescopic: as long as I can adjust the height of the horizontal pole I am happy. This could be done eg by mounting the horizontal pole on a "tee" fitting; but then how do I make it fix into a given position/height on the vertical pole (and still be adjustable)? (I had a look at this 'ible -- https://www.instructables.com/id/Third%2c-fourth%2c-and-possibly-fifth%2c-hand/ -- , but I don't understand how the tee fitting gets fixed into position: welding?)I am thinking of using pipes or PVC from a hardware store. My big question is: how can I get the vertical adjustment feature using such readymade materials? Thank in advance for any help!James KirinPasadena, CA

Leaking PVC Soil Pipe

The PVC soil pipe under our bathroom has developed a slow leak. This pipe is inaccessible as it runs under a platform that lifts the bathroom above the concrete floor of our enclosed garage. It may be a crack in the pipe (unlikely) or a connection between the tub and the main pipe (more likely). Is there a liquid sealant that I can pour into the tub drain that will seal this obviously small opening?

Can a polypropylene water main be repaired.?

I wanted to tap into a polypropylene water main.  I had some previous experience with this type of pipe in my city.  I tried to used a PVC barb fitting coupling with SS hose clamps.  But these pipes have been in the ground in my city about 30 years.  The pipe seems to be brittle with age.  I had to  use a torch to get the previous 1" pipe to slip onto the barb fitting.  It held for about 2 months, then split and began to leak at the repair.  My plumber friend tells me his company will not touch these pipes.  They just replace the whole water main with copper pipe (for about $2200!).

cleaning peeling black pipe?

Hi everyone, I finally got myself some black pipe for my project at a place where they would cut it for me. (No more EMT.) I have noticed that little bits of the black paint have come off (eg, at the place where I removed the pricing stickers) and that it is greasy all over (most probably from the pipe cutter I used at the store). I don't especially care about the condition of the paint, but want to be able to handle the pipe on a daily basis without getting greasy hands (or accumulating tiny fragments of paint all around my room and then ending up inhaling or eating them over the long term!). I guess that using water and soap on this will make it rust; how would you clean this? Thanks in advance for any advice! James

Why are these brass connectors binding up? Answered

Having trouble with brass pipe connectors. I have a M+F pair of connectors I want to use to make a ~air tight connection through a thick piece of rubber.  Want to screw the parts together far enough that the hex-nut section of each part will act as a flange, and crimp the rubber in between. However, I can not get the parts to thread together far enough.  At about 1/2 the length of either, the connectors start binding up.  I can only get the two about 1/4" away from being fully seated. Why? Are pipe connectors manufactured with a slight taper to create this? Or something else? Any suggestions?

Large plastic tube with spirals round it, like a massive toilet roll?

Hi,I need some very large pipe, between 45 cm and say 90 cm. I just need about 150 cm length- again, fairly flexible here.  either thin metal or even better probably, fairly thin plastic (say 2-4mm walls if in plastic.) NOT CORROGATED. And, ideally (pretty vital really but looking a bit bleak to find this) made in the same way as a loo roll: with one or two pieces of material that twist around each other so that the pipe has curving spiral joint along its length. Any ideas much appreciated, I don't know where to begin really. What industry should I phone up and annoy with enquiries? I 'll try builders surplus yards I guess, and I thought people who dig up roads and replace water pipes might have stuff.. Or direct from manufacturers, although so far everything I look at is just straight tube, not made in the spiralled way I'm after. CLUES PLEASE !!! Thanks, Georgie

Which surface do I measure for pressure? Answered

So this is a fairly simple question, but here it is:  If you have a 5" pipe leading out of a pressurized chamber with a 6" inch disk covering the hole is the amount of pressure pushing the disk down that of 5" or 6".  I am pretty sure it is 5" because it has the equivalent pressure pushing the other way outside of that diameter.  Now if the 5" pipe had a bore of 5" and an outside diameter of 6" would the result be the same?

Cutting PVC Pipe - Lengthwise for guttering

Ok, here's one I thought I'd throw open to the masses.... I'm knocking off the last of a fully automated self-sufficient watering system that runs completely off grey/rainwater. However, the coke can guttering is not working in this position as it has previously :(  I was thinking of using PVC piping, cut lengthwise for guttering. However, I'm working out the logistics of cutting it. It can't be cut directly in half - this would be too shallow to catch the runoff from the chicken shed. and funnel it down to the tanks, so I'm looking at removing a chunk of the top.  And I also have no table saw. Wheee. What I do have Dremel (x2) with associated cutting wheels Jig saw (With associated plastic cutting blades) Circular Saw Mitre saw Hand saws (tenon, crosscut, hack, pruning, etc) So, here's one that I'm throwing open. With the tools I have, how would you do it?  I'm leaning towards the dremel, but there would probably be issues with maintaining a straight line (not that I care about some warp, it's a gutter)   Ideas? *EDIT*  Ended up using a jig saw with an acrylic cutting blade. Worked a treat.

How do i thin out the wall of a PVC pipe?

Hi there everyone I am in a process of building a PVC bike trailer out of 40 mm PN 20 type of pipe. At the neck of the trailer where the cross-shaped yellow piece swivels horizontally - permitting the trailer turn left and right - , and just under it, where the lower red elbows swivel vertically - permitting the trailer to move up and down - are the two white pipes that i want to shave 1 or a bit more mm off of. I bought the materials but in a very interesting way the pipes don't fit inside the fittings. They need to be warmed up and then they fit inside one another getting stuck forever. No glue needed.  If i buy  the next largest fitting size - 50 mm - the gap is just too big. So it's a no go. That's why I ask you people: How do i shave off 1-2 mm of the white pipes in the picture so they slide in easily in the fittings? I want to point out that unfortunately I don't have access  to any heavy-duty machinery. So a manual way of doing this would be much appreciated.  P.S. the red dots on the picture are fixed points or dabs of glue if you like. The green dots mark out the movements of the components. For example the yellow cross is glued to the green pipes witch are glued to the red elbows witch in turn are glued to the other green pipes. Here only the yellow cross swivels on the vertical white pipe. :) I hope you got it :)

Where can i get furniture style pvc fittings in the UK?

I see so many good things about PVC pipe used for building things. In America you seem to be able to get lots of sizes of pipe and specialist fittings. In the UK  in bricks and mortar stores we are limited to just plumbing supplies. ie 21mm 32mm and 40mm pipe - we cant get corner 3 way fittings, 4 or  way, or any of the many pipe termination specials. I have a project in mind for which 25mm pipe would be ideal, but i need 5-way connectors, as well as some simple end teminations that push INTO the pipes not OVER the end. I have googled until my fingertips bleed but can only find this supplier in the UK http://www.ixi-devices.com/index.php/PVC-Structure-Connectors-Fittings-Clamps-and-Kits/View-all-products/Page-7 Frankly the prices are ridiculous - almost 6 times the equivalent US price - what goes for $1 in the states is around £4 in the UK thats just nonsense.

acceptable angle of deflection for temporary support

Hi, I am in no way an engineer.  I'm trying to figure out what is an acceptable angle of deflection for a combination frame and hammock support.  I'm thinking of using the the 80/20 t-slot beams.  I want something that is portable, easily assembled/disassembled for moving, and lightweight.  I'm go to make a box in our garden to protect our plants and when the corn is big enough, move the box around to make a hammock support(chicken wire around the bottom part to keep the critters out).  It's basically a box 6 feet wide, 8 feet long and about 6 1/2 feet high. 4 beams to make a rectangle on the bottom, 4 uprights(1 in each corner), and another 4 beams on the top to make it more rigid.  Chicken wire will keep the pests out but let me in to relax until the corn is too high and I move the frame.  :)  I'll put the hammock diagonally from pole to pole; total weight with me and the hammock is about 250 pounds.  It will be anchored to the 2 uprights with 300lb chain at each end. Using the angle of deflection calculator from 8020.net, I found some beams that had 5mm deflection with 150lbs of dead weight in the center of the 6 foot span.  I thought that even if I anchored the hammock to the center of the 6 foot span, that would be 300 pounds, more than the 250 max the hammock and I will be.  And anchored in the center of the beam is the worst case scenario since I'll be anchored to the corners. But is that an acceptable amount of give in the beam?  It's not meant to be permanent.  I won't be in it more than 2 or 3 hours tops. Thanks!
