Slide Projector Plastic Mounts

[alan_james1]

<p>This may be a stretch, but I assumed someone in a photo community forum may have some experience with slides for a slide projector. I have these Pako/Pakon plastic slides and they won't stay closed. They look like they would snap together but they don't stay shut. Does anyone know the trick to this? I was thinking maybe the knobs need to be crushed once closed so it doesn't open up. If that's the case, what is the best way to do this? Many thanks. </p>

<p>The ones that I have still laying around are a little different. They only separate far enough to accept the film frame, using the supplied jig. They are heat sealed together and once pulled open as in your example, cannot be kept closed anymore.</p>

<p>I don't remember ever having had that problem with plastic slide mounts unless I mounted a slide incorrectly, removed it, and then tried to use the same mount again. There's something wrong with the mounts you purchased, I think.</p>

<p>These can be heat staked on the little pins, I've used a million of them. Use a flat iron or a soldering iron with a flat tip on low-medium heat, works fine.</p>

<p>I've used mounts like that. The first requirement is that the film chip fit inside the shallow recess in the right half of the mount as shows in the picture. If the film chip is too large and doesn't fit entirely within that recess, then the faces of the mount won't close completely.</p>

<p>Second, when you close the mount, the plastic posts on the right half of the must go onto the matching holes on the left half of the mount, and snap in place to hold the mount closed. </p>

<p>I recall that when this kind of mount was used by commercial processors, the mount was heat-welded closed as Adrian described. Frankly, my experience was that this particular design wasn't extremely secure when they were just pressed closed. </p>

<p>You might try applying the tiniest drop of CA glue to weld a couple of the posts into their matching holes. Just be careful that you don't use too much and have it seep onto the film chip.</p>

<p>I never had [problems with them </p>

<p>I had a similar problem with some similar mounts, which I managed to solve by gently bending each half of the mount inwards (i.e. towards where the film will lie). The actual problem was caused by the mounts being slightly bowed 'outwards', so they tended to pull apart. HTH</p>

<p>I have the exact same mounts, and initially the exact same problem.<br>

I found that the small pins crush very nicely with use of a pair of pliers or a small (ball-peen) hammer.<br>

Pliers work especially well if they are the type that have a very narrow gap between the jaws when closed (due to an elevated ridge between the gripping and cutting sections of the jaws). In this case you can crush the pin without simultaneously crushing the body of the slide.<br>

Using this method very securely fastened the mounts for me.<br>

heat from a soldering iron also works but unless you're very careful, leaves an unsightly mess</p>
