Deckel SO input

[twhite]

I picked ups Deckel SO cutter grinder this past weekend. It was a bit rusty so I took it apart enough to wire brush the rust off. I was also able to clean all moving parts. Anyhow the only issue I have is it is missing the vernier scale.

I made up a brass placard today at work. I failed to take pictures. Anyhow it is the standard .005 graduation.

Now the input I need. I need to know a good method of getting everything aligned at 0 so I can bond the vernier into position.

All I have come up with is to set all angles to 0. No relief angle. Then clamp up a 1/2” tooling ball. Then slowly dial into the wheel and use a shim to make contact. Then rotate 90 degree and dial the ball forward until I make contact on the shim. Then start rotating from parallel to perpendicular and slowly adjust until I have even contact on the ball through the 90 degrees of travel.

Lock everything and re verify. Then bond the vernier to align to 0.

Am I all wet on this thought?

I am sure there might be a better way suggestions!

I’ll have a look at mine and see what I can come up with.

Thanks. I have no idea if those hash marks are anywhere near accurate.

Here is the vernier placard

I was able to affix the vernier with very little trouble. I used a tooling ball. Set all rotation and back angles to 0. Then first thing I did was set the scribed hash mark that was scribed for my approximation for zero on the vernier.
I then rotated as if I was going to grind the diameter. Then I dialed the ball into the wheel using a shim for contact.

I then rotated 90 degrees and fine dialed in until I made contact on the face using the shim.

I then began to swing the ball back to the starting position. Looking to see if I would contact or get farther away from wheel.

I then adjusted the cross slide (vernier) scale to adjust slightly. Then repeated the steps again. It took 4 tries and I am pretty happy. I need to retire a good power cord. Then I will grind a bit and check on a comparator the radius.

Need to mount the correct vernier. I made a new one today that has a longer hash mark on the 5.

Yup, way better
