Newbie- Easiest tool path for this?

[Hoverflyer.mk2]

Hey all,

I'm making a jig to mount a metal plate inside a lift fan for a hovercraft. The plate has to be perfectly cocentric inside the fan to eliminate wobbles and inbalance. I'm cutting it using an SCM Record 2 router, using MasterCAM X too by the way.

Here's the jig. Pretty simple looking part:


I've already cut up some layers of wood for it, about the same shape as the model, just a few cm bigger in diameter. The top piece doesn't have the recess in it yet. That's part of the cut.

So, first question. Is there a way I can set the stock to have the same sort of shape around the 3D model, instead of a solid cylinder?

Second question, what would be the best tool path to use to create the recess on the top layer? I have to face the top down a bit aswell, but it decides it wants to face the entire stock...

The best strategy is to turn it

So, first question. Is there a way I can set the stock to have the same sort of shape around the 3D model, instead of a solid cylinder?

If milling
Yes , draw the actual stock model on another level, and save as STL
this then can be used in your stock set-up and also be selected for verify

Second question, what would be the best tool path to use to create the recess on the top layer?

2D_Contour using a woodruff or Tee-slot cutter

I have to face the top down a bit aswell, but it decides it wants to face the entire stock...

Select a boundary for facing instead of leaving the geometry as stock defined ( blank ), use a circle that would cover the stock diameter not part diameter, if that doesn't work for you try a rectangle
