Try dialing til edge finder offsets then back off til edge finder runs true. Zero readout and do the same for the other edge then check reading. Mine came out spot on.
You should check Y axis clamp the 123 block in vise dial in center of that and shift a half inch that will tell you if your finder is off. The finder should be within .001 for sure if not its junk
Thanks. I’m sick of edge finders being off .005 cause someone messed them up. Been wanting one of these for awhile . Needed something that can repeat less than .002 without having to get a probing system
Ya, I was on the line about it until Travers had a big sale and it just fit into that months budget. I had only used regular edge fnders for the last 30 or so years so I was kind of jittery about something new. But at this point I'm finding that it just can't be beat. It really shines when trying to find the center of a raggedy bore hole. Don
Good thought, but one of those things I check off camera just to shorten the vid. You may want to look at the first video I did on the old school Dunlap drill press for a good chuck run out example... Don
That logic doesn't follow. By edge finding at each end of the block against the DRO which wouldn't care about backlash, and always moving into the piece which would eliminate backlash, the reading should always be spot on.
@@makosharkcnc7730 Hay Mako... Yes, you have to think of it like this. The DRO does not float with backlash. Its affixed to the same point in space that the block is. Its like leaving your diner fork on the plate with your meal and then moving the plate across the table. It all stays together. The glass scale is affixed to the x axis and moves with it. Backlash can occur before table (in the screw) but not at the table. That's why the DRO reigns supreme right now. Even if there was backlash as an issue that won't affect the blocks location in relation to the edge finder, and the accuracy of the edge finer is what I'm after here.
@@makosharkcnc7730 You.. I was astonished. Ive trusted my readings for years and had to do a bunch of off camera checks to see if it was for real. I did mention that 1/ 2 inch side was a lot tighter though.. which it is. Still. I guess the speed of light is faster than that of mechanical action.....

I thought this was common knowledge. You retract to true to be actual zero 😵💫
Good test. I like seeing actual data. Thanks for the video.
Always welcome! 🙂

My Brown n Sharpe .2 is within .0005 on a HAAS just like the specs say.
Nice to know. Thank you
It surprised me actually... I always say "there's no school like old school" but i guess the new stuff has to have its day too.
Runout in the drill chuck.

@@donsengine3158 Drill chucks don't run true enough.
backlash in machine

@@donsengine3158 but your moving the other direction to block

@@donsengine3158 Hi Don,
I see your point i wasn't thinking about the DRO, Your right, I'm surprise the edge finder would be that far off!
