For small repairs on cameras, I like to work with Sugru, a mouldable adhesive that can be kneaded and shaped. After hardening, it replaces plastic.




Here are two projects where I used Sugru.




Alignment of a battery contact on a Canon Power Winder F

When repairing a Canon Power Winder F, among other things, I had to solder the ground cable to the contact in the battery compartment:

The surrounding plastic melted and the negative contact came into a crooked position:

I return the contact to its original position by heating the contact with the well-tinned, wide soldering tip and then pull it into its old position with the pliers. The surrounding plastic gives way and holds the contact firmly after it cools down:

It worked:

I fill the cavity around the contact created by the manipulations with Sugru:

After the glue has hardened overnight, we continue with the reworking of the cavity at the battery contact that was filled the day before.

Smooth the area with the fine polishing wheel on the Dremel Stylo:

Then adjust the color with black gloss varnish:

The lower battery contact before correction ...

… and then:

The batteries in the retractable holder contact correctly again:

Replacement of the thumb rest on a Minolta X-300

At the front there is an X-300 that still has the black thumb rest. Behind it is the repair candidate:

Since I don't have a replacement, I have to make one.

Sugru is ideal for this.

The thumb rest from the other X-300 serves as a template for me:

I use the template as a stamp, and now you can see the fluting on the replacement:

Thanks for sharing, I've often needed something like that.

Is it flexible when cured? For non-flexible plastic repairs I have used epoxy-stick. I'll have to try the Sugru next time I need something more rubbery.

I use Sugru on several of my cameras to improve the ergonomics:

Quite stiff, I would say.
