You drill out the router mounting holes to fit the eccentric spacers, 7.5 mm?. Place the mounting screws through the holes in the spacer and backplate and secure them with a nylock nut. Should have a mil or so of tram adjustment.
Have not quite worked out if you need 2 or all 4. I am installing my new Z-axis slide router mount Friday and planned to do this mod at that time.
I suppose you could do it to the backplate but that could be expensive if you mess it up. Router mount is way cheaper to replace.
I did the mod yesterday but the snow here is keeping me in the house today. Seems to be good. The thing is I reused the existing holes for the router mount and drilled out one of the ones on the left side. I left the lower left one as a pivot point.
If it ever stops snowing, can’t get to my shop. Should be able to go tomorrow. A foot of snow in an area that gets on average 1-2 in per year. No plows, no road clearing, they only try on main roads so it’s up to you to get to the main road.
The eccentrics are all started in the neutral position and rotated in the same direction. I suppose you could do the same thing with just one and enlarge the holes for the other three but I’m afraid it might slip under load.
I don’t have a way to measure run out but my machinist square says it is at a dead 90 degrees to the waste board.
I had about ±1/2 mm of adjustment.
If anyone has any ideas how to measure this please post.
Haven’t c gotten to nod yet. Something about these sliders is they come with some unused holes that could be tapped for a couple of grub screw that’s can be used to adjust nod.
