Surfacing Spoiler board

[Christian Knuell]

Hi,

what bit am i best getting here in the uk and how do i create the toolpath for such a cut and given tool , I'm using mdf for a sacrifice board.

for MDF almost any tool will work - it is very easy to machine.
Just try to get a rather large diameter to save time - it also has the benefit (or disadvantage depending on how you see it) that you'll immediately see if your spindle is aligned perfectly perpendicular in relation to the machine bed. If the tool leaves palpable marks the spindle should be aligned until the marks disappear.

Creating the toolpath is simple: just draw a rectangle of the required size and create a pocketing operation. You can e.g. do this with Estlcam:

(Pocketing is explained at 4:52)
