i fully understand what to mean, for this reason i was expecting to plow ‘from both side’. it would need to have parralelality between faces to ensure results but i was applying the same concept as planning end grain : come from both side, don’t go over the edge from one side to the other.
I also expect that the end grain face of the wood would not be too visible inside the groove once made. so any discrepencies made visible by the planing direction overlap should be quite negligeable. Paul would most certainly says this is mostly wisfull thinking 😀
Thank you so much for this insigth, i ll have a look at it again, that could be a decent training and a new jewel box for the wifey in the mean time 😀
