It's a long weekend here, so I spent it getting my new Mamiya M645 up to scratch.
Let's see. In no particular order:
The gear train between the film insert and the frame counter was sticking, so the frame counter didn't reset reliably when I pulled the insert out. I took the gear train apart, cleaned it, greased the pivot points with light lithium grease and reassembled it. Now it works perfectly. While there I took the opportunity to clean and lubricate the rest of the gear train.
The seals around the film door had turned to mush. Cleaned the goo off with lighter fluid and kimwipes, and replaced the seals with foam courtesy of Jon Goodman.
The aperture coupling lever had a little bit of a bend, making it so the lens didn't stop down during an exposure, which was easy to fix.
The baffle under the lens mount was scratched. I stripped off the paint and repainted it with matte black lacquer, oven baked to ensure good durability.
The mirror, focusing screen, and lens above the focusing screen were all dirty (mainly with goo from the deteriorating mirror bump pads and flocking. I washed them in isopropyl and distilled water and refitted them.
The flocking had turned to mush (see my thread about flocking). This was probably the most time-consuming job. I cleaned it out with a bamboo scraper, lighter fluid, kimwipes, and isopropyl. I then painted the exposed surfaces matte black, and finally fabricated new flocking from black card, which was held in place with neat gummy double sided tape (from micro tools - they sell it for fitting leatherette). Getting the pieces just the right shape to clear the pivots etc for the mirror was a challenge. It took (counts) four trial pieces for one of the sides before I was satisfied with the fit.
The mirror bump pads were gone - cleaned the goo out and replaced with foam from my trusty Jon Goodman kit.
The leatherette on the front was scuffed, and didn't survive removal to remove the front cover. I made a new piece with leatherette from Micro tools, which matches the original stuff remarkably well.
So that's about it. It's been a real hoot, and I think it's just as good now as the day it came out of the factory.
