A good chance that I'm overthinking this, but would like to run it by some folks with way more experience than I. I'm making a cylinder square, that I'd like to grind after the 3"x6" 8620 cylinder gets carburized( Will do a practice grind before heat treat, to get it close ). Planning to use a Harig Lectric-Center on my 612 grinder. My dilemma is, the spindle on a Harig 612 is spring loaded, which pushes the wheel towards the column( away from the operator ). The Lectric-Center is also spring loaded, but in the opposite direction. So, there's no way to do the side wheel grind of the rim on the "good end" of the cylinder square, with both spindles in their most rigid direction. Any opinions on which one should be the rigid one? Obviously very light cuts will need to be taken. I'd imagine it will still need to be fine tuned with lapping, but I would like to grind it as close as possible first. If it's a wash either way, I'd opt for dressing the side of the wheel facing me, as it will be easier to see what's going on for both dressing and grinding. That would put the grinder in its most rigid direction, and just take super light cuts on the end of the work piece.Thanks for any opinions on this.
