Spoil Board Resurface Question

[garymkrieg]

First time resurfacing a spoil board. A new piece of 3/4" MDF, what would be a good starting depth to remove?

[wb9tpg]

I usually draw pencil lines all over mine and then take off 0.01" at a time. I repeat if the pencil lines are not all gone. Hopefully you're talking about a new piece of MDF you added and not the original bed.

[garymkrieg]

Yes, a new piece on top of the aluminum bed.

We remove .01", then flip it, and remove .01" from the other side.

WHY both sides???

He might do it for a couple of reasons. But, since he runs a big honking industrial router my guess is so that they can pull a vacuum through it. Or, some things tend to warp if you only remove material on one side.

Ger21: Need to have a conflab with you so will be sending a PM to get your sage advice and words of wisdom, etc.

Yes, to pull vacuum through it. You need to surface both sides to get better airflow through it.
