The thread is about bending some 1" stainless tube with a hand bender, for Heavens sake.
The thread is about bending some 1" stainless tube with a hand bender, for Heavens sake.
The thread is about "bending stainless tube. The size is not relevant it about how tube can be bent.
Yes the method does depend on several factors the 2 main ones are the quality of the bend and the tightness of the radius of the bend compared with the diameter of the tube.
Just because you have bent a piece of tube with a hand bender does not give you and in depth knowledge of the subject.
As the saying goes "A little knowledge is a dangerous thing"
Almost as dangerous as a little 1970's knowledge.
The OP asks "Is it possible to bend 1" x 1.5mm walled tube on an ordinary floor standing conduit bender? "
I answered him with the suggestion that an old style Hilmor bender will do the job.
You gave him incorrecct advice because the OP asked "if a floor standing bender will ben 1" stainless steel". floor standing will NOT as you later posted.
The old style Hilmor bender is a floor standing bender and as you said you had to bolt it down to bend the tube so the answer to the OP's question is NO and as the Hilnor bender is a floor standing bender the answer is still NO
Stand alone if you tried to bend and 1 " stainless tube the resistance to the bending load would tip it over. As you found you needed to bolt it down and using the feet the support tubes would tend to bend unless you put extra support. . This is what electricians used to use to bend steel conduit and plumbers would use to bend copper tube. Most conduit is now PVC so ease to bend on a bender like this.
Not stainless steel tube. needing a quality bend.
You don't get a University Degree without being able to read and more importantly comprehend what you are reading.
You don't get nominated for membership of a professional Engineering institution without reading/ comprehending and applying what you have proved you can apply to other existing members of that institution.
So what you are saying is that your little experience in bending a couple of pieces stainless thin wall tube than some one who has getting on for 60 years Engineering design experience with direct experience of designing tube bending equipment for a professional (paid to design equipment by a long standing Engineering company part of a major UK Engineering Groupe of Companies) Engineering Designer.
Its you who keep talking about using a Professional to install equipment so don't you need a Professional to design the equipment of does the design just appear from thin air.
You may be a Profession (paid) installer of electrical equipment do the people who design the equipment you install not have experience like you.
Also if you can bend a small thin tube for a hand rail or hoops for a cockpit cover you consider yourself and expert in Mechanical and Electrical Engineer .
You also consider anyone who has been educated in the theory and practice in a subject at a University to have limited value and th person who installs the equipment are the experts.
Now you don't say this but its what you mean.
You need to stop insulting people when you cannot get your own way.
As you had said to me before stop digging.
That's all just your usual deflection Roger and it's not what i said at all.
I said the Hilmor bender will bend 1" stainless, i know this because i have one and have bent 1" stainless with it. I don't need a degree to know that and i don't need to be an expert in tube bending, which is good, because i'm not and have not claimed to be one.
The Hilmor bends 1" stainless, end of.
I'll leave you to continue on your own, i'm sure you can argue without any help from me.
Why don't you two find a room and chat it over with some beers?
Personally, don't need no pigging bender, just do 1" with me bare hands.
If I can interrupt the arguing for a minute gents and answer DownWest's comment. The tubes not flattened its just the way the lights catching it. The bends are all pretty consistent. This was a "cheater" bend, it's used for calculating the sizes and makes it really easy, I learned this from an excellent you tube video where the guy was making roll cages.Have to say, but the bend in the first photo looks a bit flattened, but can't see it very clearly.

I thought I would follow up my original post. I bought one of the Chinese pipe benders shown, cost about £90. It bent the frames from 25mm x1.5 stainless but required a 2m piece of scaffold tube to get enough purchase. I will post a picture of the finished arch when I get there.

I have one of those, Had it for 40+ years - it has cast iron formers though, not aluminium-.will bend 1 inch stainless tube that the OP started the thread about with ease. No need to bolt anything down, No need for extension handles other than the standard ones supplied, The only problem is if the leg length hits the floor in which case one has to make adjustments.

Smithy,
Sheridan Marine's split jaw canopy bar clamps, clamped round the push pit would be more secure than the tabs. I think you will find the tabs for the aft poles cracking over time, assuming they are welded on.
