The EASIEST way to countersink, NO TOOLS required!

[designfactore]

Hey Guys,

When countersinking the laser etched holes in my Rostock Max kit, I started out using an Exacto blade and peeling up the layer of melamine as suggested, which was a pain, when more than 3/4's of the way through the build I discovered the absolute EASIEST way to do the "countersinking", and you can do it as you go along with the intended screw in hand!

So you have the flathead screw in your hand that you want to install in a laser etched, countersink marked hole:

--Just take that screw, insert just the tip (yes, I just said that!) into the hole just as deep as you want your countersinking to be
--now, maintaining that depth, you simply tilt the screw so that the tip leverages against the side walls of the hole, and A PERFECT ROUND STACK of melamine will pop CLEANLY out!

Why does this work so well? Underneath the top layer, the internal particle board seems to be a densely packed, layered material itself.

When the laser etched hole is created, the laser apparently cuts past not only the outer plastic layer, but also several layers deep into the underlying material. So what is sitting there isn't just one surface ring, but a stack of them. Prying with the screw in the above fashion simply prys out that hidden stack! How much of that stack is up to how deep you put the screw in. Just the tip! LOL

Happy building!
