Do you recognize this adhesive used under end pin?

So I was swapping Schaller's for Dunlop Dual Design. The Schallers were coming loose.

Discovered a bit of a mess under the lower strap pin. I don't recognize this adhesive. It's still kind of flexible. I think someone must have patched (temporarily) the end pin with something. I've picked away a bit of the excess, but I don't want to create a problem that leaves the strap button in this bass unusable. (Got a gig tomorrow)

I'm also thinking the only way to properly repair this is to plug with a dowel in matching wood.

So I have these questions:
  • Anyone recognize what adhesive this is?
  • Anyone know where to source a small purpleheart dowel or plug?
I'm going to temporarily reinstall the existing strap pins because I have a gig tomorrow.

For the record, here's the other strap pin. It's actually the looser the two:

Ugh. Yeah, that looks like some kind sealant-type glue. If it's rubbery, get it all out of there.

Yes, the right way to fix that is to drill it out and glue in a nice-fitting hardwood plug. Then re-drill the pilot hole properly and maybe use a longer screw.

I don't know anywhere that sells pre-made purpleheart dowels. I can make you one, if you like. I have a lathe set up specifically to machine custom-size plugs and dowels from wood, and I have plenty of scraps of purpleheart. You can reach me by PM here on TB.

the top one you can fix just fine with a toothpick thickly slathered in wood glue, screwing the pin back in while it's still wet.

that bottom one is a disaster, like bruce says whatever that gummy crap is in there has to come out.

i'd shove the toothpicks in there so that it holds tightly enough to get through your gig, but afterwards yeah, that's gonna need some drilling and cross-grain plugging.

Yup. That's exactly what I just did

I'm baffled why whoever did this didn't just fix it the usual way. Whatever they used was probably more work than standard materials. :banghead:

And I definitely plan to fix it properly when I have some down-time. Bruce, I may well take you up on your kind offer, once I have a chance to take proper measurements.

Woodcraft has purpleheart pen blanks. They should be pretty cheap and one could be made into a dowel or use a plug cutter. There must be one in or near Chicago. Or, have Bruce make you one as long as your temp repair holds long enough to get it shipped to you.
