Default How do I open a can?

I would like to open this OCXO without damaging it. It is a metal can soldered around its edge. The size is about 2" x 2". Any recommendations welcome.

Just a guess... put the whole thing on a hot plate and take a small brazing torch to the business end with a small pry bar lift up on the cover. Careful knowing there's wires attached.

Use a Dremel with an abrasive cutting blade to cut through most of the solder. Pry it open.

+1 for the Dremel.

I have diamond disks which in this case I'd use in preference to the stone disks which cast off a lot of grit.

you forgot to mention it sends off shrapnel everywhere when it gets caught and shatters.

Thanks for the tips. I am afraid the case and the internal part are tight fit, not giving place for the thickness of the Dremel blade. I probably try with a gas torch.

And what about the rounded corners?

Heat... well, this is the problem. The big mass of the enclosure conducts away the heat from the tip of my soldering iron. Perhaps a gas torch would do, but I am afraid that I damage the internals...

What are you trying to save? The guts or the case? Sacrifice the case like we said above - cut it and pry it open.
