Hi guys whats the technique for using the self tappers? Has anyone got a guide with pictures?

Im getting the wosshing noise on full boost and just after abit of advice really

Cheers guys

Put them together on a workbench.

Drill pilot holes. 3 or 4 are enough. Go through the plastic into the metal collar.

Pull them apart and clean the swarf out

Put back together, put in self tappers.

I put some araldite around them too to stop them ever coming apart, although this was probably a bit unnecessary.
