Looking for the damn Roller Frame pdf manual...

Anyway, there is a way to compensate for this with bolt mesh by cranking up a frame to the desired tension, measuring the total deflection (bowing) then when setting up the mesh in the frame before inserting the lock strips, you release a measured amount of mesh from the clips at the center of the frame. (half the deflection amount at each opposing roller).

I've done it for some lower mesh count frames that I cranked up past 45 newtons on 23x31's. It helps.

Don't think it can be done with panel mesh unless this compensation is built in.

Are the new one's from GSG powder coated blue?  I thought that any newman that is blue in color is of the older design without the changes I mentioned earlier.  I'll get back with you on that for clarification to see if perhaps I am wrong and maybe some of the blue frames are of the latest design.  Any newman roller with blue powder coating is a few years old, I think.

I am also looking forward to your thoughts on the newman flash panels.  I've been holding off on buying new mesh because of financial reasons and I just haven't made up my mind as to what mesh I really want to go with.  I'm leaning heavily towards the murakami smartmesh with S threads, but I really want to give the newman flash panels a ride before I invest a $1K in mesh.

Yes, they are blue.  And I ordered them from GSG last week. I think they had been used at a show because there was emulsion and ink on them (another thread/story altogether >:( ).  So they may have been sitting around there awhile.

These are the first flash panels I have purchased, so we will see how it goes.  It may be awhile before I test them, but I can't imagine there being any great advantage if I can't get the Newtons over 30 without the severe bowing.

Alright, I got some clarification on the blue m3 frames.  The m3's are still powder coated blue so I was wrong about that in my previous posts.  They are going to stop powder coating them one of these days, supposedly.
