Fabric riveted?

Have any of you ever seen a sonerai 2 with riveted (or possibly PK screwed) on fabric on the horizontal stabilizer? I’ll be recovering the tail on my new plane anyhow. But I thought it was to be rib stitched. I’m concerned that whoever put the new fabric on the tail must have drilled into the tail for these rivets.

Drilling into the ribs for rivets instead of stitching is fine. As long as they didn't drill into the tubes which they shouldn't have to. Very common.

I riveted the fabric on my 2L’s tail,surfaces and then put 2 inch tape over them,works just fine. There’s a tape that is supposed to be used under the rivets so the rivets don’t directly contact the fabric.

What did the rivets go into? The actual tail tubes? Tabs? My concern would be weakening the tail. That and competing metals. I mean why not just rub stitch? Lighter, cheaper. I mean the fabric is not coming off with modern materials.

The rivets would be used the same as rib stitching in that the fabric would be secured to the ribs only. The fabric is glued to the leading and trailing edges. If you are recovering, and want to rib stitch, go ahead. It makes no difference as far as performance is concerned.
