Instructions / use
- Mount jig on the Surface Grinder; you typically will have to remove the magnetchuck. You need Spanner #22 for this. Check that the surfaces are clean - so that the jig is mounted parallel to the table. It will be diagonal. This is intentional.
- Ensure the jig is clean (so the knifes will seat well/flush)
- Ensure the knifes are clean (so the knifes will be tightly packet)
- Put the knifes in the jigs; hand tighten and then tighten the bolds gradually; in several stap. To avoid asymmetry/building up needless stress.
- Puth the endstoppers as far left/right as you can; but where they still easily 'lock' in place.
- Lower the wheel over the knifes until you can just about no longer have a piece of (thin) paper in between. Err on the side of 'too high'.
- Gently check that it also does not touch (at all) at the far left/right
- Start the wheel. Move table forward so that the wheel is just 'before' the knifes.
- Start motion & coolant.
- Now gently lower the wheel in small steps until it just touches (usually at the far left or right side; the middle is often a bit lower.
- Make a full pass; then go down in steps of 5 or 10 until all nicks and scratches are gone.
- Best to use fairly small steps in the Y direction; and towards the high end for the X travel. You will see blueing if you dwell too much or try to take too much off.
- Step down (just) 2; and do a 2 final passes (or 3 if it it still touches somewhere) - i.e. letting it spark out. It may take a bit - as something seems quite heat/expansion sensitive.
- Remove knifes & use the wetsteen(speksteen) to remove the burs on the back.
