Foreman Spoilboard Surfacing with MASSO Wizard

I am completing the assembly of my Foreman and have an issue with surfacing the spoil board. I am using the MASSO Wizard for surfacing my spoilboard. I have made one pass and have small ridges about evey 9/16 of an inch on the front half of the spoilboard. So far the only material removal is the front half of the spoilboard. Nothing removed form the rear half yet. My table is 4x4 and 2x4 frame with two sheets of MDF for the top. I am using a 1" Whiteside surfacing bit, model 6210 with a PWNCNC 2.2kW water cooled spindle… Where as I am using a 1" bit I have programmed the wizard as if it is 3/4". My Wizard settings and a picture of my spoilboard ridges are below. I would appreciate any thoughts on how to get rid of the ridges on my next pass. Is it as simple as stepover?

It looks like you need to tram the spindle in better to me. A line every 9/16 is probably equal to the step over of the tool.

Can you feel them or just see them? I’ve had where you can see them but not feel them. If you can feel them I agree you probably need to tram.

Looks like you need to tram that spindle!

There are several good videos on how to do it on YouTube. It’s not difficult, and worth the time.

I can feel them the ridges…

Hey Mike,

there is a video for tramming the milling motor by observing the visible patterns a surfacing bit leaves behind:

The Mitz Pellicciotta method, which is a method that works the better the larger the bit diameter is, because it looks at the direction of the patterns such a bit makes when it is not perpendicular to wasteboard surface, works only as third step after you ensured your machine is

  1. rectangular (“squared”) (bar gauge) and 2. coplanar (“not twisted”) (fishing line method).

Only then I would proceed with

  1. Tramming the router (Checking for perpendicularity between milling motor axis and (different areas of) worksurface)

IMPORTANT NOTE: Surfacing the wasteboard does help nothing if the machine is not accurately rectangular (“squared”) and coplanar (not twisted)! Not at all! All your workpieces including the wasteboard will remain a parallelogram and be twisted if you don’t ensured steps 1 and 2 accurately.

Finally you can check the tramming of the milling motor. One of its adjustments is made with the forward/back tilt of the two steel hollow shafts by adjusting their adjustment bolts in the black anodized axis ends (see Support: Tramming - Front To Back for details). If the tilt differs on one end of the axis from the other end, the milling motor will tilt from one end to the other and make the line it mills with your v-bit slightly deviating from a right angle.

I will review the input and the various videos and try to get this done in the next few days. Thanks for all the advice…especially the always forthcoming Aiph5u! You are a wealth of knowledge!
