Thanks for the dimensions. My parting blade is 0.089", and the small grooving tool is 0.05". The grooving tool works much better on steel. I have a suspicion that the P-2 Empire T blade will be kind of challenging at 3/32" thickness. I'm almost there. It just looks like an issue of power, although there is some instability with the steel parting. I guess it is going to require a really steady hand for the 1.5" steel. I don't look forward to it.
