Don’t try wood screws

It also seems to be more abrasive on tooling than steel, particularly the phenolics that have linen as a substrate. Its a great material with many uses.

Wood screws are cheap low strength designs anyways. If the screws need to be strong, I use screws designed for metal.

I did drill and tap my phenolic workbench to support the excellent Jorgy benchvise I bought from a member here.

For those who haven’t tried it, you’ll be surprised how well wood will hold a machine bolt with a tapped hole.
Lee Valley Tools has (had?) a technical bulletin explaining the use of tapped holes in wood for machine bolts. Includes test data eg threads in oak vs maple.

Unfortunately the bulletin appears to be no longer readily available but maybe someone saved a copy?

Even better, drill and tap the wood, hen a little super glue to firm it up.
I saw some testing that just tapping hardwood worked better than threaded inserts.

I used 1” thick phenolic material between the plywood platforms to maintain the correct tolerances for a snug fit over to rip guide.

I’ll move that bottom screw before I make a cut.

These may be of interest. Very similar (too similar??) content.
