Received parts for what Felder calls "Precision Miter Unit with Pin Locating System". Installation was straight forward and can be done in 15 mins, just read the picture captions to get an idea. The Xcut fence now locks at 5 deg increments up to 45 degree with a special stop at 22.5 degrees.

Felder missed an opportunity to make the calibration unnecessary. Any self respecting Felder owner really dials in the 90 deg stop, if Felder increased the length of the indexing bar by couple of inches and added a hole for 0 deg no calibration should be required.

I will place the parts list in the files section in few days and also report on how well it actually works. Since there is no slop to speak of, I know that I can get it to at least give me 45 deg every time. That alone is worth the parts cost, under $300.
