Upgrading LR3 to LR4 in Seattle

Diving into the core build momentarily.

A question popped up.

Before I cut my x rail conduit to length, I’m wondering if I go with what the calculator says for a 48" width (54.625"), or if I should measure based on my existing table.

The center of my old rail to the center of the other track is 56.5". This was for the 48" cutting width for the LR3.

Edit: hmm, I see the calculator says 59.375 table width, for the default width rails. Edge to edge, my table is 62" wide. So I’m probably good, just need a little longer rails.

“Given a table x inches wide, my X rails should be X - 4.75 inches” seems right and the calculator agrees. 57.25 it is.
