I recently bought the redline x point setup tool for use in aligning my home
shop machines and wanted to share some observations.
Overall, it sucks. There is very little that is good about the unit except
for the plastic carrying case.
After spending half an evening aligning my table saw with the unit I have
some specific observations. Some notes:
Almost all the machined threads were poorly cut requiring me to chase them
before assembly and useage.
The base extrusion was anything but flat and left marks in my tablesaw
The camming mechanism to remove slop between the bearings and miter slot
loosened every pass up and back down the miter slot requiring me to
retighten it for each measurement run.
The styluses provided for the dial indicator did not seat flush to the end
of the indicator shaft making precision absolute measurement completely
impossible. Which makes any attempt to measure any angle completely
When completely extended, the plunger on the dial indicator read .01" short
of 1". This could be fixed with a shim on the back side screw if I were so
The finish of the extrusions and machined parts is really poor. Lots of
stray tooling marks and edges with burrs.
With lots of patience and the help of a machinists plate I was able to align
my blade to the miter slot to within .002" (the tolerance of my flat plate).
After my miserable experience trying to use the unit I did a google search
and found a review of the unit at:
After reading the review I can assure you that all the defects the review
found were consistant with what I saw on my unit.
In short, the thing is almost completely worthless. I'd have saved myself
lots of time and trouble if I'd just bought a dial indicator and made my own
alignment fixtures. Buyer beware. And for what it's worth, I have no
affiliation to any company selling anything, woodworking or otherwise.
Hope this helps,
