I am building up a 95 Schwinn Homegrown as a beater bike for use around town. Is there any reason why I can't install the headset bearing cups by carfully banging them into place with a piece of wood and rubber mallet.
I know that conventional wisdom says use a headset press, but I am not sure why? Thanks.
You don't need a headset press, but you also shouldn't pound on them with a rubber mallet either. The cups need to be pressed in very evenly, which is hard to do without supporting everything. If the headset begins to go in at an angle, you can damage the headtube (by making it oblong).
But there's a simple fix. Use two blocks of wood (maybe 1 by 4s) and either a c-clamp or a vise. Put one block over the bare headtube end, and the other on top of the cup that you're pressing into the frame. Then slowly tighten the c-clamp or vise, watching to make sure that it's going in straight. If it really fights you, use the rubber mallet to tap on the block (the one over the cup being installed).

You can make a homemade press with a bolt that is long enough to pass through two blocks of wood with a few washers to keep them from pulling through. Works great. 🙂

Let me add. Sometimes I have found the fit a tad too tight, so it was necessary to file off some metal beforehand.

Wish I had such a huge vise!, a C-clamp I would say. That's my own way of doing the job, being an amateur cabinet maker it was an easy guess.

Use a threaded rod with hefty washers and nuts at each end. I bought such a device from Nashbar many years ago, and it works fine. You can easily make your own. Make sure the frame is properly prepped.

Friend of mine did that. Says it works great. I prefer the Park press at the LBS. Costs me a 6-pack of beer each time, but it beats buying a $125 tool! That's not quite 21 presses before the tool is saving me money. I've gone through 5-6 so far...

i hear this all the time.. so i made one. when i tried to press my first set of cups with this set up, the first one went in like butter, true and easy, the second one wouldnt go in straight no matter what i did. so i ended up tapping it in with a block of wood and a hammer. it took forever, becuawe i did it in such small increments so as not to risk an oblong set, but it works dandy. the headset bolt-nut-washer press would work perfectly if i had some spacer inside the steering column to hold the bolt centered. everytime the bolt got even the slightets bit off center, it would then press the cup in off center. next time, ill just turn myself a couple spacers on a lathe, five minutes work, but do know- its not infallible with just a fat bolt for a headset press!
(personally, i think the wood block method, if you are careful and judicious and Slooooow will provide results as good and as damage-free as any.)

In such cases I prefer to (judiciously) use a file to improve the fit. It has to be tight, but not so tight.

Yes, that would work, I suppose.
Campagnolo "GO-NOGO" gauges are the right tool, followed up with the appropriate mill if indicated. This is trivially quick at any competent LBS.
I read here frequently about clever and time-consuming work-arounds to shop installation. Personally I view this like home engine assembly. Even the practical man send out the valve grinding and things of that nature. The service charge is small, the tool cost is high and there's no reward for suffering.
OTOH I have corresponded recently with another r.b.t. afficionado whose tales of his LBS's incompetence, rudeness and ignorance would lead one to go to great lengths to avoid them.

I've done this a few times before I got my threaded rod and washer head set press. It works, but you need to be carefull.

It is faster and there is less chance of damaging the headset.
