I'm a low-tech guy with very limited space. Funny, because I used to repair power tools and could build myself a power taper tool if I wanted to. But do I want sawdust powder all over the house? No. Having birds is messy enough.
Basically, I live in a very nice townhouse that borders national forest (I pick mushrooms in my "backyard") but we don't have a garage.
I use the Tru Center taper tool. I've had it for years. It was passed on to me by a guy that bought a Woodchuck. It works great for me. I'll admit ash shafts are challenging, LOL!
I use a brush to seal my shafts. I use one of those "sponge" brushes and I cut a groove in it to ride along the shaft and I just paint on the sealer. I lean the shafts up against the firewood pile on the front porch to dry. I've been doing this for years. (Though for a couple years, I was leaning the sealed shafts along the wall of our lanai when we lived in Hawaii.) This has always worked for me and provides activity for snowed in days in winter. I seal the shafts after I do the tapers. This is necessary.
I also crest totally by hand. Paint very simple crests by hand with red ochre and black paint. Primitive crests, but my own mark.
Whatever you do, have fun doing it and make your arrows your own.
