Hurricane Nuts - Use Ply Backer? (1 Viewer)

[Garret_O]

Hey all,

I'm building a set of MTMs and I had a quick question regarding Hurricane Nuts. On my sub project (in finishing phase) I didn't use any backer on my hurricane nuts when installing. Unfortunatly, I pulled out two hurricane nuts during the process (when testing the screws). I was using gorilla glue around the hurricane nuts and then installing them and clamping.

Has anyone else had problems with Hurricane tearout in MDF??

I was wondering if I should glue 1/4" ply to the mdf and set the Hurricanes in that for the MTMs. Another option would be to use standard wood glue and not ploy/Gorilla.

THoughts?

Everything pulls out of MDF. I always use a thickness of ply or OSB when using either "T" or Hurricane nuts.

Also use epoxy not Gorilla glue to hold the nuts in

I used the hurricane nuts on my sub but I mounted them from the back side of the baffle. Never had a problem.

When I've used them, I also have mounted them on the inside of the baffle (used epoxy), and it was 1/2" ply on the inside of the 3/4" MDF. I like threaded inserts better, BTW.
