MDF Rings question

I've used self-tapping sheet metal screws with good luck.

What size did you use?

Whatever size I had lying around that wouldn't go through the door panel //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Some people use cutting board instead of MDF because MDF can have water damage.

That is nothing that a little resin won't cure Either that or paint and clear coat it.

I was going to go the HDPE cutting board route to make some 6.5" to 8" adapters for my mustang, but I have way to many scraps of MDF laying around. That reminds me, I need to step away from the computer and get back to wrapping up my GD installs:emb:
