A tip for anyone fitting a removable handrail into a slot “telescoping”, with round tube or square tube always tape your ends until they fit snug into the tube, then fit your slots with the handrail still inside the tubes onto the stringer for your stairs and either bolt or weld, take your handrail out of the slots and remove the tape, as long as the hand rail was built square, it will always just drop into the slots and always slide out of the slots with out a hassle. A perfect example is using 1 1/2” ID sch40 pipe for the slots, then making the hand rails with 1 1/4” OD round tube, leaving you around 1/8” or around 3mm tolerance around tube tube when centred, using the tape helps get that perfect fit on all sides of the of the tube and the the pipe. And remember to put a chamfer on the inside of the pipe and remove any burrs on your tube, this will allow the hand rail to “find” the slots and just drop right in.
eksine I do use my head . I do this a lot and the big problem as he talked about is the inside weld seem that had to be ground out to allow for telescoping and to test fit the desired materials to be used. Because what he talked about in ID and OD and wall thickness it’s hard to find materials of a exact fit. All I was doing is conferring what he said. I’ve been working with steels for 50 years so I know the up’s and downs
I was looking for the required difference in the OD of the inner tube, and the ID of the outer tube. In the video, you say that should be .010". but, the graphic you show indicates .010" between the two tubes (which would be a IDouter - ODinner of twice that--.020". Which is approriate?
Yeah, how about as a manufacturer you provide ID (and OD) width and radius dims? And get all your MFG buddies to do the same? Or make some with the inner weld removed? OR best, how about if you PRODUCE specifically engineered, REASONABLY PRICED, purpose built telescoping square tube? There is a HUGE market for it.
Been making portable tower's on many occasions and use several guides, internal and external NEVER had one jam and can be made is 2 to 3 days depending on the Height required. the extruded seam weld is NOT a problem but in some instances can be a weak point. Got me stuffed what toob is It is T U B E . Now as for antennae I have made several HF Antennae that are portable because everything is telescopic , Boom, Elements and Tower.
He REALLY scared me at 2.47, I thought I REALLY had pissed him off or something. So I QUIT talking through the rest of it, and smacked my kids too and told them to shut up this guy wasn't playing around.

Thinking of building either a tilt over or easily extended and retracted telescoping ham radio antenna mast of approximately 20m/60' length (perhaps slightly less). I'll be knocking on the door of the local MS shop and hopefully I find the helpful staff you speak of. Wondering about the weight I'd be pushing up and locking in place at each max extension point with a 20lb antenna system at top or even if that is possible without mechanical assistance. I'll work it out I guess.
Thanks for your video I am planning to build a telescopic hydraulic cylinder lodging 80 tons. With 27SiMn material. What is the best metal treatment and rates suggested of Hardness. Roughness. Yield. Tensile. For my application And Wich method of manufacturing is more common or suggested hot rolled or cold rolled Thanks again
I spraypaint windows and doors and had the idea of 2 vertical lengths on the end of a horizontal length with set screws on all 3 bars and holes i could screw the brickmold to., Then i could paint both sides at once rather then prep again for the opposite side.
I need to make 18M mast , for loading capacity to hold 2 round antennas for accomunication. Would you please suggest the material or alluminium grade I need to use for this. My terrain and area has rough air and salty water in my atmosphere, near to sea
Hmmm can I ask why square tube is better than round tube, I did not find any reason why it is? I am stuck with choosing round or square tube for my design.
I need to build a telescopic pole using a hand crank but don't know what parts and crank to use also how to run the cable to the crank inside the tube. Can someone help? Thanks
I was hoping to be given some standard sizes that would be good for telescoping, But after watching the video I am still in the dark as to standard available sizes showing wall thickness etc ?? :(
Same here. Still completely in the dark. If there were some sizes given, I would jump in my iron horse and go buy them from my local Metal Supermarket. Called my local store and they didn’t have a clue either. How can this be so difficult?
"Diameter" refers to circles and spheres, not to squares and rectangular tubing. Wikipedia: "In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere."
I like how he gets serious and puts the tubes down and pauses after telling something important
I missed it. Timestamp please. Thanks.
Never in my life did I think I would need this but here I am and thanks;)
very rare that a video gives me exactly the info I'm looking for. Thank you!!

Thank you. This is wonderful. You have just changed my life.
Hi Popcorn, if this changed your life, I suggest you buy chips...
You need to get out more. 😉
Spiritual Popcorn - if this changed your life you need to get a life.
I really like metal supermarket. Bought quite a few pieces for projects. You guys are doing somethhing right Jason. Thanks for the vid!
Very helpful! Thank you!
Very helpful, thanks!
Thank you so much for the video.
I buy from you guys all the time in Portland, Oregon. I’ve had to rotary file the inside of the tube a lot to make fit
next time just cut off a new end, they use fast shitty cuts. use your own cut off saw, dont waste time filing, use your head

I'm glad you made this video
Thank you for interesting explanations. I want to make a car bed like Notel and this info very helpful for me!
Could you please include info about compression pictures and other ways to secure the tubing under load
Not even gonna lie using this for making a collapsible bong

Fireball tools has a video on how to make a simple tool to cut the weld seam out, ruclips.net/video/3jr4Capx8XI/видео.html
Alcobra Metals in Spokane is now offering telescoping tubing apparently with the internal weld removed, with a shopping cart.

His previous job was a mob gangsta boss, and that's the look he gave to his subordinates when they fucked up a wack job.
I thought the same thing....I found myself straightening up :)
@@Dan-qp1el Homey not playing around, he will take the tube and telescope it around your head.

Do you carry 7/8 od.aluminum square tubing
Thank you very much

What is a good telescoping tube with the spring button mechanism that can hold a lot of weight? Say under 400 pounds or so?
what did you find out?
Thanks
If cone geometry design for telescoping tube have many use including folding ladder, to adjustable frame to fast deploy tent

does anybody have any idea how telescopic poling mechanism work ?
I want to make an adjustment height weight bench

is it possible to telescope a 2.5” square hollow with 2.25” ?
1.6mm wall thick
Why do you recommend square tubing over round?
Doesn't rotate while extending or retracting
Square doesn't roll off your bench
Hello sir, i want a telescopic boom to move my video camera vertically from ceiling wirelessly.
For porn?
I've seen people put plastic to make the right distance between ID and OD , does anyone know the name of this or method?
shims
To think I can’t find a piece of this telescopic tubing in Australia 🇦🇺 unreal
Locking system for telescopic tube?
Why is square tubing better for telescoping? Could you let everyone know that they won't find DOM square tubing.
Can i get square DOM?
He just said so
And.... vertical antennas
2:47 Poor guy looks like he's trying so hard to keep his mind out of the gutter.
How did this comment make it to THIS video lmao
"Diameter" refers to circles and spheres, not to squares and rectangular tubing. Wikipedia: "In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere."
It's pretty easy if you know how to use a tape measure and do math
Pity you could not have given an example of telescoping tubes.
Very strange fella'
