I don’t think the thickness is a big deal, however if the opening in the black grip is bigger than a 1/2″ it might be a problem. The reason this would be a problem is because a 1/2″ pipe is used to core foam out of a sanding block. I guess one could core with 3/8″ copper pipe if the grip opening is bigger than a 1/2″. Keep in mind that a lot of this DIY stuff is trial and error. If you by the grips and it doesn’t work, you are only out $2.00. One more thing, the yellow foam isn’t really squeezing the inner foam, it is more of a perfect fit and glued in place. Together it makes the foam sensor the same diameter as the piezo element and this is important.

Is the thickness of the yellow foam critical?

Walmart has a pair of handgrips for $2 with black foam grips, but the foam doesn’t look as thick as your yellow foam.

Is it the outer foam squeezing the inner foam for support, what is important? Or is there another factor?

Thank you for your help.

Yes!

You would have no support of the foam coupling if it is just the 1/2″ foam core. Without the outside foam it would look like the Leaning Tower of Pisa.

Is the outer foam necessary?
