Problem with mounting driver, need help (1 Viewer)

[Greg P]

I have just finished my sealed 1503 project. I am using t-nuts into the MDF to mount the driver. I have 2in 10-24 size screws. The sub is a small cube, so on 4 of the 8 screw holes the t nuts extend infinitly into each side wall. On the sides that dont I only have an 1.5 in of thickness. On those hole mounts I notice one of the screws swelled up the Mdf and put a small crack in the back layer. I drill as much as I could out with the T-nuts already in. Should I just get shorter screws or is there somthing else I can do.

Thanks

Color me confused. 4 of the 8 holes are in the edge of a side/bottom/top? If so how did you get T-nuts installed?

An MDF edge will always split when put under that type of pressure since it's basically layers of paper made from saw dust

The T-nuts on the far reaching edges of the circle run into the sidewall. The baffle piece covers the whole front and was assemble in a "sandwich configuration"

Am I OK using screws that are only an 1.5 or so?

Sorry, but I think that even with predrilling, any size screw is going to force the MDF apart if it penetrates the edge of the side wall and is torqued down.
