Issue with dovetail bit on Morgan Hop’s Wasteboard File

Hey Jason,

I don’t know to which “V-bit test” you refer to, but usually, surfacing is done as soon as the machine is ready for use. But it is not ready for use before it is checked and adjusted for rectangularity and coplanarity. Before surfacing, have you ensured your machine is

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

Surfacing the wasteboard does help nothing if the machine is not accurately rectangular (“squared”) and coplanar (not twisted). All your workpieces including the wasteboard will remain a parallelogram and have a twisted surface if you didn’t ensure that steps 1 and 2 are done accurately.

Furthermore, if rectangularity and coplanarity are not perfect, the Y movement can block or have “hiccups”.
