A deep dive into the MiNT SLR670 'Type I' battery adapter for SX-70 cameras. Repair & modification

A few videos ago I released a monster hour and a half episode all about Polaroid i-Type adapters:
• The Ultimate Guide to ...
In that video, I briefly mentioned the MiNT SLR670 'Type I' adapter, but I did not go into much detail about it.
Well, I ended up having a few of these cameras end up coming my way, so I figured I'd make a video about it.
This video all started because a client of mine asked if I could convert his MiNTSLR670 Type I into my PolaVolt battery solution instead. Why? Well, this client had already purchased another camera from me that was pre-installed with a PolaVolt, and they liked it so much that they wanted their collection to be consistent.
One of the aspects this video talks about is how (early versions of) the Mint battery adapter panel makes opening and closing the camera difficult. This is due to the plastic side panel being too thick, resulting in the erection arm grinding against the side of the panel. I should note too that this is an issue that sometimes affected the original model cameras due to molding issues and or/warped body panels.
This issue, although annoying - can be fixed, as I will demonstrate in the video.
I reached out to MiNT for comment on this - who informed me that this problem is now fixed on current revisions of the adapter. They also offer services to rectify this issue and I've had a few clients reach out saying that they were able to send their camera back to MiNT and have the opening/closing issue fixed.
I was very happy with how fast MiNT responded to my emails too. Quite possibly the most rapid customer service I've ever experienced!
