Preparing the Mighty Boy - Nut insert tool.....
Captive nut inserts have been used throughout this project - here is a sample of my favourite tool in action.....
This is what the tool looks like - 4mm nut inserts are being used here....
You simply drill the correct size hole, put the nut insert on the tool.....
Put it into the hole and squeeze the handle to compress the back of the insert....
(These are great for thin panel work as well)
