Recently view a you tube video from Trent Manning about measuring from bedbar pivot bolts.
Always wanted to do the same but couldn't figure out an easy way to do it.
This is my version I came up with for my grinder type.
Amazon linear digital gauge.
Not to expensive 50$ Can + -
I'll be using to old mounts for what looks like stone sharpener.
Installed 10 mm bolts.
Drilled out holes in lol near center of bedbar pivot bolts.
Mount to bedbar and then use the holders from grinder.
Gives an accurate area to measure from.
Had a piece of aluminum plate and cut a couple of slices in it to mount gauge.
Test fitting it to a piece of 3/8 rod I had around the shop.
Installed rod then attach plate to it.
It can also adjust in and out If I needed to.
Like this.
Turned out pretty good.
Brand new bedknive I had ground as per grinding instruction to find that this on was of by less than a hair.
Checking to see if by moving it back and forth on rail If the readings stay consistent and they do.
This bracket that came with gauge I just flattened out to attach to the end so I can adjust top or front face by just tipping bracket to the side a bit.
Top face
The add bracket stays on to catch the bedbar pivot bolt in either top or front face grinding
Front ... notice the bracket is tipped to right to catch the pivot bolt.
A couple of videos
So now when my leading edge is worn back on top dress days and touching both ends for set up leaves it a bit off I'll be able to set them all up the same and back to the correct front face.
Should be a game changer in this situation for sure
