Setting up support for backdrop

Okay, I'll admit : you'd think that it would be very obvious how to set up a backdrop support but no, not for me

Any way there were no instructions, I've never seen one up close or assembled for that matter.

It's made by Interfit and can't figure what snaps and screws into what!
So any way be gentle and guide me please.

I have the two support stands, 3 piece cross bar and two brass pegs and other pegs already in the stand.

thanks!

That sort of sounds like mine. The brass pegs go in the top of the leg stands. There should be two of the three crossbars that will have slots that fit over the brass pins.

With mine I use the third crossbar if I use the wide background paper. I have set screws in my crossbars that can be used to make sure that the bars don't come apart. The fit on mine is so snug that I've never used that feature.

For narrower background papers the stand is designed to leave the middle cross bar out. I think that it's obvious that you place the no-seam paper roll on the crossbar before you put the crossbar on the leg stands. Although none of this is very heavy it's a lot easier to do all of this with two people, especially raising an lowering the height of the stand.

The rest should be obvious I should think.

I have the same system. The Interfit website has a basic diagram that will at least show you how the brass pins are supposed to look:

There should be a tool in your kit that you can use to adjust the set screws on the crossbars, if necessary. My crossbars were pretty loose, so I did adjust mine.

Thanks Dave.
The thing is that when I finally did get the cross bar to sit, it just seemed to me that the bar should sit on the pins in a snug manner too, yet they seem not to.
Any way I finally have it set up, thanks for the response.

Awesome thanks. Well that's how I ended up doing it so the diagram confirms it's right. I suppose it was obvious yet as i mentioned above when you slot the cross bar on the brass pins it just seems an odd seating.

Thanks for the link

You mean the loose fit of the crossbar on those brass studs?

It is a loose fit so you can inch up the height of the backdrop crossbar. You can alternately increase the height on the support stands (one side then the other) until you get it to the height you want. You can do this in 18 inch or so increments.

If the crossbar fit onto those brass studs in a perfect fit, you would not be able to do this unless you had two human beings doing it at the same time (with a tight fit if you tried to raise only one support, the other support would tip).

So in this case the mechanical slop is engineered in.

When you try to turn a rectangle into a trapezoid, you must allow the corner angles to change (the slop accommodates this need).

But, with gravity so predictable and consistent, where is the crossbar going, even with a loose fit?

How do you guys stop seamless paper unwinding from the roll? I use sticky tape, but do not prefer this method. I was thinking of making rubber stops which I'd push in to the tube and stop rolling...

Big alligator clips can hold the roll from unrolling when rolled up for storage or unrolled

Are you talking about plastic clips or the ones with metal teeth? Wouldn't that damage the paper?

Use hand spring clamps, often called "Pony" clamps, due to a popular brand of that name.

The "Pony" brand is made of metal but they do not have teeth, but smooth flat jaws that are covered with a vinyl. But even when the vinyl wears off the smooth flash jaws will not damage paper or cloth.

There are also plastic versions of these hand spring clamps that work fine also.

These will not damage your paper.

"Alligator" clamps do have "teeth" and should be avoided.

Enjoy! Lon

Thanks Lon,
that's what I've founded too, alligator with mean teeth Otherwise I have plastic clamps that I use for glueing, I shall try them with seamless too.

these clamps.
