Adam Froehlich Posted June 22, 2020 Share Posted June 22, 2020 There's considerable play in the mounting points for the 15mm rod bracket on my Arri MMB-2 matte box. It seems to be on a part that can't simply be tightened, but is embedded. It's just a tiny variance at the actual rod, but that little bit gets translated into a considerable wobble at the top of the mattebox once it's mounted on rods. Does anyone know how to tighten this up? Are these little mounting points threaded into the mattebox itself, or embedded? The mattebox itself is fairly new, bought new Winter 2018, and has really only seen light work in the studio (only 1 or 2 operators/assistants) Photos attached, Video for reference: In the video, the mounting bracket is rock solid on the mounting points, it's the points themselves that have movement.

Gavin V Murray Posted September 12, 2022 Share Posted September 12, 2022 Have the same issue, I've taken it in to Adorama and they clamped it but it came undone again pretty quick. It's been a thorn in my side for a while now. Link to comment Share on other sites More sharing options...
Premium Member Dom Jaeger Posted September 12, 2022 Premium Member Share Posted September 12, 2022 If mechanical means - clamping or punching to expand the press fit - isn't working, use a gap-filling retaining compound like Loctite 609. Link to comment Share on other sites More sharing options...
