How to mill out Depron on F3P models
On light-weight models made of Depron there is a significant weight-saving
potential by milling out the Depron in selected areas. It is a quite easy
process, the steps below explains how I have done it.
 |
First of all you will need a milling machine, I had an old
and battered Dremel laying around and bought a milling unit to fit.
It's quite cheap. |
 |
Then you need a milling tool. I had a Dremel type 196
in my tool-box and have used it, the bigger diameter #115 is probably
better. |
 |
For professional use you will need a set of forms to mill
after. For hobby use it's quite OK to draw directly onto the Depron with a
pen and do the milling free-hand. For best result, start in the middle of
the area to mill and move outwards by moving the mill in clockwise
direction |

The assembled milled test-model, a Morback. All the
Depron before milling weighed 53.3g, after milling it was down to
34.8g. Assembled without any equipment as it is in the picture it
was 47.5g. |
