Before you ask, I did a Google search but didn't find exactly what I was
looking for. I just finished (nearly) a nice Arts & Craft Cherry coffee
table and there are some noticeable blotches on the top. They are not
severe and will probably fade into the background as time goes by but I was
wondering if I should have done something different.
It was finished with several applications of Tried & True Danish oil
followed by a few coats of T&T Varnish Oil. The blotchiness appeared after
the Danish oil was applied. So now my question - Is it acceptable to use a
wash coat of dewaxed Blonde shellac under the Oil or would that detract from
final appearance? I have tried it on a couple of pieces of scrap but
thought I would solicit some opinions from the more experiences finishers.
Since I have three more tables to make for the house, I would like to do a
better job on the rest of them.
Staining is NOT an option but I would appreciate any help this wise group
can supply.

Yes, using a blonde shellac is quite acceptable. I'd use a 1# cut to seal it
first, and that should reduce the blotching without detracting from the
final appearance.

When do you want to use the shellac? Before the Danish or before the
Varnish? I've used the shellac after danish oil, with success. Also used
it after T&T original polymerized linseed oil, with a long curing time.
I haven't tried danish oil over a shellac wash coat. It hadn't occured to
me. I have some cherry in the rack that seems to have a more open grain to
it, where that might work well. It almost seems as though it was steamed
in the drying process...

I have been able to eliminate or at least reduce blotching on cherry
by using 320 grit or finer with a ROS. Then I use a Bahco 6" cabinet
scraper. The surface should look polished with this method when
done. Scrible using a soft pencil on it's side befor scraping to see
what areas have been done if you want. (Try a small area first.) Run
the scraper with the grain and "downhill", similar to how you would
run wood thru a planer.
I also use a scraper on poly between coats but not afer the last coat.
I hold the scraper about 30 degrees from vertical and about 30 to 45
degrees to the grain. I pull the scraper and keep it bent slightly so
the corners don't dig in. Staining also is more even on a scraped
surface.

Blotches in sheen or color?

It sounds as if your blotch is sheen-related. The varnish in the
varnish oil started to give you a build coat when you stopped
applying it. Give it a few more coats and see if it evens out.
As to shellac, I'd have used it after a coat or two of the danish
oil after it had cured for a week (- month) or so if I was going to
use it.
