Checking the closing action with the old toolpost. Works great. |

Brave guy! I wouldn't even think of slitting that much steel. Maybe brass but not steel. |
| vtsteam:
Well maybe fools rush in! I haven't done much slitting -- although did my older steel tool holder the same way a few years ago. But, I was pretty cautious, took half a dozen passes at it as slow as I could crank the table, 160 rpm at the cutter on a 3" x .032 blade, used Synkool water soluble coolant sprayed on. Didn't seem to be a problem at all. Just took my time. Pretty quiet, no heat. Was a little worried about the breakthrough at the end in case the kerf closed up, had one hand on the stop switch, but that didn't happen either. It was actually a piece of cake. |

I suppose it depends on how much residual stress is left in the block - if it had been normalised it should be OK, but untreated cold rolled could be quite an issue. |
| vtsteam:
It was hot rolled, faced on all sides. |
