skid plate install

[RX1]

I'm installing a skid plate on my RX1. Seems to me I read last year a warning about how to install the threaded plugs in the belly pan that the plate screws into. Were they being overtightened or stripped? Anyone remember or have any advice?

No, you need to use good machining practices when working with aluminum, and some made the holes too big. I would suggest spotting the holes from the skid plate, prick punch them, drill them smaller, and leave about .015" for the finish size drill...carefully drill this last size..don't wobble and make the hole too big (forgot what size drill I used). You want the hole somewhat tight, so you can just tap the rivnut in. Then carefully use the tool to expand the rivnut, so the rivnut does not turn in the hole..even a little will make it weaker and not let the grooves bite in properly..then just tighten the tool and they are in for the long haul. Now if the plate does not line up perfectly, just open the holes in the plastic until it does. But if you have someone hold the skid plate while you transfer the holes, it should come out well. And make sure you do not drill into anything expensive inside. Mark your drill bit for depth.

Thanks Sumpbuster. I'm off to the races!
