Just follow Leica's very basic, very simple instructions. As MadnBad says.
Winding it on with the base plate off - "to make sure it loads correctly" - is a big mistake as it needs the tulip on the bottom of the base plate to correctly position AND tension the film.
Why is it that people just don't follow Leica's instructions?
I loaded the film as post 2 suggested. I always snug up the film, backwinding to check if the leader is pulled forward when winding. I think it worked. I did see the film advance. When I shoot tomorrow I can confirm if there is slippage.
Most people new to the tulip spool over-think the loading process. With the exception of needing a third hand to hold the baseplate when loading, it is deceivingly simple.
I hope it works, simply doing what it says under the baseplate should work flawlessly each time. But irrespective of 'read the instructions' there is in the film advance mechanism a clutch and this may be faulty. If it slips again try loading the film and advancing it without the baseplate on so you can see what is happening, ok, you waste a few frames or even a roll.
That is what he was doing which was causing the slippage.
It's because it needs the baseplate attached as the tulip provides correct film tension and placement. "Testing" it without the baseplate on proves nothing as that is not how it is designed to work.
The only time I have EVER had film slippage was when I loaded my M4-2 (the first M I had with the quickload) the incorrect way by winding it on with the baseplate off. Because online 'experts' said that was how to load the film.
I have had zero film load failures since, running hundreds of rolls through my M4-2, M5, MP, M-A, M7, MdA by following Leica's extremely simple and clear instructions. Plus you get to shoot 38 exposures on a 36 exp roll of film, as nothing is wasted!
I think you should have thought that through first.
The tulip provides the correct film placement by aligning the films sprocket holes with the cogs on the sprocket wheel (shaft), by pushing the film down and against the light spring inside the film take-up spool. That is all the tulip does, the only tension it applies is passive. If you engage the sprocket holes onto the cogs yourself that does the same thing. It is entirely possible to wind a whole roll of thirty six through the camera and not have the baseplate on, and the film will be tensioned correctly unless there are any other problems with the camera. The point about telling the OP to try without the baseplate on is so he can see if all aspects of the film advance are working together as the film advance lever is wound. So is the take-up spool turning and can it be seen to slip, are the sprocket wheels turning and not slipping. The sprocket shaft is disengaged when the film is rewound, so If for example the sprocket shaft isn't turning it won't be dragging the film through the camera, which in turn would mean the take-up spool won't be taking any film up and give the appearance of it 'slipping'. It wouldn't be out of this world to then suspect the film rewind mechanism which disengages the sprockets isn't reengaging the sprockets when a new film is loaded.
Edit - I assume the OP has made sure the rewind lever is in the 'Up' position when trying to load the film. It should of course snap upright on it's own the first time the advance lever is wound, but if not the film transport sprocket will be disengaged.
Without the baseplate/tulip attached, the film's position and tension is not consistent. It can move laterally.
Either way 'we' are jumping ahead. The OP first needs to see if he has issues now that he is loading the camera correctly.
I think perhaps you 'jumped ahead' wanting to score a point but omitted to check you knew what you were talking about.
The film cannot move laterally once you have the sprockets engaged with the sprocket holes in the film. That is the point of the quick load system, it automatically engages the sprocket holes with the sprockets using the spring inside the take-up spool and the tulip. But it doesn't stop you engaging the sprocket holes yourself before replacing the baseplate, or to leave the baseplate off while investigating possible faults. I think perhaps you 'jumped ahead' wanting to score a point but omitted to check you knew what you were talking about.
Then please explain why doing that can cause slippage even after you replace the baseplate.
Also, kinda rude post, no? Things rough for you today?
I don't disagree the first time you have the camera. You look and doublecheck until you're sure.
But I've shot precisely 3 rolls through an M5 and the last roll I just shoved it in the takeup spool and closed it up. Once it's on the sprocket, it's on the sprocket. There's nothing more to do. It does NOT take many repetitions to have that muscle memory down, and you can tell when the film is aligned. It is as low a fuss as most any manual winding camera I've used.
.. When I shoot tomorrow I can confirm if there is slippage.
Inspired by this thread, I grabbed my M5 and a roll of Tri-X, and loaded the camera per Leica instructions, following the picture of how the film should be threaded into the take-up spool. Put on the bottom with tulip, advance film, and once again the film had slipped out fo the spool. So I looked at how the film seemed to be able to move about in the spool because the factory load has a tongue — the full width of the film is cut down. I simply trimmed off the tongue, pulled out a bit more film from the cassette, loaded the film into the take-up spool per instructions, put the baseplate with tulip back on, and voila — loaded in a snap, no problems. The fact that the film is full width when placed in the take-up spool make all the difference. For me, problem solved.
