Default RE: Rib stitch help

ORIGINAL: jim52519


Hi All,
I am building a 87" Ziroli Stearman. I covered the airframe with Stits dacron and paints from F&M. I installed the pinking tape and used a T pin to dab on glue blobs for the rib stitching. I used Elmers yellow carpenters glue. The glue blobs became hollow as they dried. When I lightly sanded the wing they turned into volcanoes! Up close they looked bad!
They were unacceptable.
I am in the process of sanding them off. I made some samples using 560 canopy glue . This was better but still had a noticeable depression in the middle. If I did not have the pinking tape on I would use the thread method ,but it is too late for that now.
What glue can I use that will not sink in the middle, or how can I modify the glue I have. How about epoxy?
Any help would be appreciated!

Thanks
Jim
Jim,

The rib stitching goes under the reinforcement and pinking tapes. Another way is to cut short pieces of thread, and adhere them to the covering with dope, and then add the reinforcement tapes, then the pinking tapes. You don't want these to bee all that visible, but just to appear that they are there.
