3 roll seamless background holder

I am setting a up a home / garage studio and was looking at getting one of these. -> http://www.amvona.com …ge&view=1&produ​ct_id=1502

I was told that humidity will cause the 107" seamless paper cardboard tube to warp / bend / sag, making it hard to roll up the paper.

It was also suggested to get a metal insert tube like this ->http://www.dennymfg.co​m …=com_virtuemart​&Itemid=26

I also heard that you can use 2" (?) PVC which will work just as well and cheaper.

Has anyone had any experience with this problem? What model / product would you suggest and would you get the metal or PVC insert?

ofcoarse I am trying to save a dime since I just bought 4 bees with everything that I thought I would need from Mr. Buff. ($2300.00 = ouch)

Yea I know... Now I am trying to be cheap after spending that amount of money.

Thanks

Have a look at this Manfrotto crossbar:

It's what I use with my background system & they work great & are made of 2 sections, quite rigid, & lightweight. I tried using 2in PVC but wasn't happy with the result due to sagging of the tube.


I have an Amvona DSE-8 roller system mounted in my home studio & it works very well. I don't think Amvona puts as much up for open auction on ebay as they used to, which is a shame. I won 2 of the DSE-8 kits on Amovna ebay acutions & won each for less than $60. They may not match the quality of the Manfrotto Expan Drives, but for my purposes they've been more than adequate. Unfotunately Amvona seems to do mostly Buy It Now on ebay, but it's worth checking on ebay before buying from their retail site or doing a BIN purchase on ebay.

I can't imagine that the seamless core tube would warp enough to be a problem at any humidity level that would be tolerable to humans. My system is mounted in my living room studio so I can't say for sure, though.

Good luck!

I have one of those sets and I dont use the cross tube. I have mine set up in my basement and have yet to have any problems with warping of the tube. Since paper is so cheap you might give it a try without the cross tube and see what results you get.

If you want to use the crossbar, just visit your local electric shop and look for a conduit tube and choose the one that you like.

hmmmm, good idea.

I see a couple of advantages to using a crossbar:

1. You can plan your mounting of the brackets & cross bar length for the widest paper you ever plan to use but retain the ability to still use narrower 9 ft rolls if desired or required on occasion. (If you use the AutoPole or similar non-permanent mounting then this isn't relevant, of course.)

2. You can mount non-cored paper, muslins, or canvases by attaching them to a crossbar using tape or clamps. (That said, IMO the best means of handling muslins is a track system.)

As already pointed out, cored paper doesn't require a crossbar so maybe the best solution is to mount your 'normal' seamless w/o using a crossbar but have one crossbar on hand for those occasions when it might come in handy for shorter rolls or a canvas. For a crossbar, I really like the light weight & 2 piece construction of the Manfrottos.
