Lamination clamp?

Anybody know of a clamping mechanism for transformer laminations? Like when making transformer, pressing the lamination into alignment?

Maybe there was a short glimpse of such a thing in a recent manley factory tour video..?

Other than that, I'd just search youtube to see what others do. I'm pretty sure that this is not a off-the-shelf tool :-)

This is a DIY situation for sure. Almost no transformer making tools are in reach of the small guy, other than winders. Most transformer manufacturers make their own tooling for stuff like this.

If it were me, I'd try woodworking corner clamps and a couple of bench clamps to hold them around the lams. Like in this picture, but with the squares cut down to size and turned towards each other, holding the lams in between. Then use the bench clamps to hold the opposite sides of each angle tight enough for the job.

Whether you think you can or you think you can't, you're probably right.
