My set for dimensioning at the moment includes Veritas Custom #7, #5-1/2, #4-1/2, Veritas scrub plane and Veritas shooting plane. I start with scrub plane then go to #5-1/2 that has blade with big camber. And finish dimensioning with #7. Once joinery is done I go to #4-1/2 to smooth showing surfaces and prepare for finish. And a saw followed by shooting plane replaced me miter saw, that is to make ends square.
Not being critical here, but that would be a punishing regimen. I tried out one of the very early custom planes - LV sent it to me for feedback, and I later sold it. It was a well made plane ,but with a V11 iron, I could not do the same volume of work that I could do with a wooden try plane before resharpening.
the plane design itself ( that was a 5 1/2, cap iron and all, same effort of cut with each sizing beech planes from rough to make planes) created a lot of friction. this is somewhat shocking (less work removed between sharpenings) because V11 abrades less than half as fast as the iron that was in my try plane, and still is (w. butcher, which are sometimes soft, but this one isn't so much), and in a contest of taking thin smoother shavings, I'm sure the V11 would last more than twice as long.
I spotted brian holcombe early on using metal planes. Lie Nielsen for a jointer, and I don't remember what for the jack. I told him I'd make him a pair of planes at the cost of material and it would lighten the load a whole bunch, and I'm guessing that he's still using them from time to time, though his business volume increased a lot forced his hand on buying some high quality machinery.
That said, a metal jointer is nice to have along with a wooden try plane of about the same length of a metal jointer both for match planing, and also if you're stuck doing a lot of rough edges where the volume of work isn't really that high, that can wear the center of a try plane and you can spare the sole with a metal jointer. It's also probably true of the volume is really that big, it's easier just to do the work with the wooden plane and correct the sole afterwards.
Cosman and a lot of other gurus try to point people toward an all metal plane regimen for dimensioning wood and I think it's not going to be possible for someone using all metal planes to not tire of it and look for machines quickly. the level of friction for the newer premium planes adds a layer on top of that, both on long grain and end grain.
if we were all in a town somewhere that people could come to my window, I'd refit wooden planes for everyone who had an otherwise solid older plane - I guess it's not always that easy to do if you don't do a bunch of them, but it's usually a 10 minute exercise for me and maybe an hour to make an attractive wedge on the odd circumstance that a wedge is so out of shape that it can't be saved.
If someone *wants* to use machines instead, there's nothing wrong with that, but working from end to end for a while with hand tools will make someone a better woodworker, far better at sawing and planing once they go to machines, and less likely to get stuck altering designs or sticking to plain flattish work just because it's easier to figure out how to get it through machines. As soon as machines became the norm, work got ugly and boring pretty quickly.
