Tie tack vs. bar pin backing

[sydnie7]

The two types of clutches can often be mixed/matched with different pins. That is, you may have a nice clutch on hand that will mate to a new pin that comes with backing plate for glueing.

But the pin length is critical, and some pins/clutches just don't interchange.

I suppose you could snip off the pin from unused tie tack and, as you say, glob in on with substantive epoxy. Working around old sports cars as I do, I've seen stranger things done with JB Weld!

The "pinch" type pins don't work well when put through several layers of fabric. I've had a few tie pins fall off with that type of back.
