Saeco mold handle alternative?

The $48 price tag on a set of these is a bit steep. I have a 3 cavity mould that I acquired and like to use. Perhaps a Lee handle could be modified?

Yep , I use a chainsaw sharpening file to open up the screw holes a little bit .

I have drilled out the mount holes of a set of Lee handles for use with a 4 cav. Saeco mold, works as well as the Saeco handles I use to have.

I drilled out the holes on Lee handles and they broke.

I have chain saw files. I’ll give that a try. Thanks all!
