The trough is constructed out of a 1 gallon thinner can, cut with tin snips and bent (I have four of them). I set the action on end, then rotate a section of hammers into the trough, which I fill with a mix of lacquer thinner and acetone (the acetone makes it evaporate out of the hammers faster). I like to set up a few sections and have them soaking (put something over them to keep the fumes down), swishing a little back and forth. After maybe 15 minutes soaking, I raise a section at a time and blot out as much of the thinner as I can with paper towels or equivalent. Usually I repeat the process (depends how extreme the problem is). I find I get most of the lacquer (or keytop or whatever) out of the felt using this method, though there will always be a little residue. In any case, the hammers become workable again. Since yours are not installed, other setups are obviously possible. I do think that soaking with a little agitation is the most efficient method, as opposed to pouring thinner onto the hammer felt and letting it run out.
