>Or, you can simply use Dyna 2 paint stripper and skip the whole procedure.
 One application, wait overnight, scrape it off, done.  It's biodegradeable
and doesn't have any of the nasty solvents.

>>     As you all know, stripping old finishes is one of
>> the most disgusting aspects of restoration and, after
>> 30 years, I stumbled across a procedure that is ALMOST
>> non-totally-disgusting, and didn't even rot my brain
>> or wreck my hands !!!! This may seem dumb and
>> elementary, but I'm gonna describe it, directly. 
>> 
>> Get: Get at least 2 gas masks from auto-paint supply
>> stores. I get 3M ones for about $20 each, here, and
>> they work great! Disposable, and a  lot cheaper than
>> at Home Depot or Lowe's ( And I wonder: If I warm
>> them, can I get the solvents to evaporate back out
>> from the activated charcoal, and extend their life ???
>> ) Get several pairs of stripping gloves, gallons of
>> denatured alcohol, quarts of 
>> "Citra-Strip", stripping pads ( the D-handle with the
>> rough blue pads, and the finer green ones ) and a
>> brass-bristle pot scrubbing brush, like grocery stores
>> sell. Also get a  bunch of large sheets of cardboard,
>> and a  plasic tarp. I get boxes from the local futon
>> shop, which are like 
>> 6' long, 4'wide cardboard trays, with 2 halves. 
>>    Put the plastic down on the ground, outside, put
>> the cardboard down on top of it, put wooden blocks or
>> plastic bottles with flat sides down ( like small
>> isopropyl alcohol bottles ) to keep the piece up off
>> the cardboard a  bit, and put down the piece to be
>> stripped. Blooge some stripper into a  glass or metal
>> bowl, and dunk the handled-pad into it. Wipe it on
>> quickly, without a lot of brushing, and wait a 
>> half-hour. Come back, scrub the piece with the grain,
>> with the pad, creating a  sludge, then scape off the
>> resulting gloop with a plastic putty knife ( round the
>> corners to prevent scratching. )  Then dunk the brass
>> brush into some alcohol in another no-spill container
>> and scrub with the grain. This will get old filler,
>> finish and varnish remover out of the pores of the
>> wood better than anything, yet leave no visible
>> scratches. Wipe up the residue with paper towells, and
>> wipe and scrub some more until it is clrean enough.
>>    Advantages: The Citra-Strip doesn't go through the
>> gas mask and poison you like "regular" strippers do.
>> Neither does it penetrate/eat the gloves, like other
>> strippers do. So, although it's twice as expensive,
>> initially, it will FAR MORE than make up for this,
>> both in savings on gas masks and gloves, AND in saving
>> your brain from destruction, and the destruction of
>> the nerves in your hands !!!!! Similarly, the
>> denatured alcohol does not eat the mask, your brain,
>> the gloves or your hands like "hotter" solvents do,
>> like lacquer thinner, for example, yet cleans away the
>> residue beautifully.  The cardboard soaks up spillage,
>> and the plastic keeps it from going into the ground.
>> And if I DID spill a  little ( though I'm careful not
>> to ) I'd MUCH rather it were alcohol, a wood
>> distillate, that evaporates quickly, than lacquer
>> thinner. And no water is used, so the system is safer
>> for veneer.
>>    Put the soiled cardboard under a roof somewhere,
>> if it is going to rain, until the solvents evaporate
>> away. Then re-use it, or throw it in a  dumpster when
>> it is thoroughlky dry. ( An EPA-acceptable way to get
>> rid of the stuff. )
>>    Thump
