How to bolt on a spoil board onto 3XL? HELP ME PLEASE

There was a thread recently about this.

Milling through frame base for spoilboard

You don’t need or want very many holes to hold down a spoilboard. Just mill holes where you know you’re clear. No, just make sure to set them below the surface. Not necessarily. The MDF will bulge if they’re too tight. I’d recommend using a scrap and test a few sizes (milled by the SO3). That’s how I have mine done.
