Resurfaced my, (new to me) Walker-Ceramax 618 magnetic chuck

[Janderso]

This chuck works the way they are intended.
The B&S chuck that came with the Micromaster was in bad shape.
I practiced on the old worn out chuck.
Fresh dress on the wheel with lots of coolant and got it done.
I let it spark out on the last pass. Smooth as glass!
I’ll try the 5 block test later.

The 5 block method only tells you how good of a surface you have of the mag chuck. Should you have a horizon to the machine ways the the 5 blocks will be arched to the curve. To inspect the ways of the machine you need a neutrally sported beam to be ground on top and bottom faces. This can be done with a 1"x1"x12"-18" bar held in a vise in the middle and two equivalent hight risers on both ends. This is such that the beam is not subjected to the pull of the magnet. after grinding you will get a barrel shape (opposite to an hour glass) double the error of the machine's horizon.

Nice surface grinder.

Hugh,
I thought the 5 block test was the deal.
Makes sense now that I think of it.
I am a novice when it comes to surface grinding, and most other things too

Mighty nice looking mag chuck there, Jeff!

 

[Janderso]

Why, I’m glad you noticed.
Not only does it look nice but it works perfectly.
I purchased this beautiful chuck from Bemnychree

 

[Winegrower]

Man, I wish I wanted a surface grinder!
Nice job, Jeff.

Looks good! How do you guys keep your equipment so clean & good looking? Even when my stuff is cleaned up it looks bad by comparison.

 

[Janderso]

I'm not into pimping out my machines, I am more interested in maintenance.
This surface grinder came to me in very good condition.

So did you ever get the valving figured out on the machine with th e return stroke? Finish looks good what wheel did you use?
