Quick and dirty taper pin pusher

What John York (benmychree) said. Make damn sure what end is the small end and give it a good whack, supporting the work if necessary to prevent damage to stuff like bearings, and to make it more rigid so the hammer and punch blow does not just flex things. On installation you do not have to (or want to) beat them in hard. The pin will stay put with just enough medium tapping that it is set. A really tight or press fit is not required or desired.

So that's one vote for no tack weld. Duly registered:)
 
Trick is gentle tap with the largest Hammer you can find as it is the energy transfer...thing Newton balls.

But that press is sweet!

There appear to be places on my shaper where the manufacturer went to the trouble of blending pins into the surface such as on the hand wheels.
That was very common back in the day. After the pins were installed they were filed down flush with the surface they were driven into. After painting, they would pretty much disappear. Which is nice until you want to take it apart decades later with no idea how it was put together. Still, I have done that myself with taper pin installations. I think it leaves a nice looking job, and it also makes the pins easier to remove, after you find them!

My real life has left me obnoxiously opinionated on matters relating to design and I'm pretty sure I still would put the SB7 on my list of Ten Worst Designed things I've been around (too bad they're so pretty:). And that surprises me because my Ten Best would all be really *old* things... Since there was some guy back at the SB mothership who had to occasionally take them apart, I'm wondering if there was some convention of which end was which you could tell from looking at the surrounding context. Or, if the guy assembling them had it in for the guy who has to fix them and randomized it:)

If the pin was drilled while the machine was being assembled, than it is quite likely that the fat end of the pin is toward the easier accessed position... But you still need to check it. With work done on the bench, anything is possible. I doubt that much thought was given to the poor guy who had to remove and replace the pin in the field...
