The hammers on this mid 80's Baldwin are full of lacquer. I soaked them in lacquer thinner and have blowed each one of them out with high pressure about 10 times so far. The hammers have puffed up some (which is a good thing IMO) but the lacquer staining is still there. I'm assuming the stain means the lacquer is still in the hammers. Should I be using something else to remove the lacquer?

I typically start with 1 or 2 drops per string impact line. YMMV...experiment with care.

I've been reading about all these ways of changing hardness of hammers for a while.Nobody mentions where you can get this Ballistol, cause I don't recall ever seeing itin any supply place in my area that carries it. Maybe I've led too sheltered a life herein the great white north, of Canada. So , please enlighten me here , and I supposeI'll be surprised that it's likely carried by Home Depot or some such.CT Winnipeg.

The nice thing about voicing with Ballistol spray can is that it is impossible to overdo it. You never lose the forte but gain pianissimo and piano. If you don’t like the smell add a drop of Balsam oil to each hammer and it will smell like a Christmas tree.
I just voiced a Kawai from the 70s that had the hardest hammers ever. It took about 5 oz of Ballistol dosed proportionately for the size of the hammers. The owner could not believe the result and it took about 5 minutes.

Joe,As far as the Baldwin hammers are concerned, they do respond pretty well to Ballistol without lacquer removal.
I really am doubtful in regards to the stuff's ability to negate the problems on overly lacquered hammersEspecially those that have been like that for more than 10 years. I'm one who has to see/hear it to believe it. Perhaps, IF we ever have another convention and you and I can get together on some POS/PSO?I'm thinking the carrier/pressure in the spray can may have some effect along with the magic oil within.
The Kawai, I agree, is just a rock hard hammer but it does respond to Ballistol the same way. It just takes a lot in both cases.
Define "a lot" please.
It saves hours of needling. Steinway hammers require less treatment in most cases.
II am one who uses needles as a last resort in the voicing scheme of things. It destroys fiber continuity imo.Which "Steinway hammers"? Pre 1970's? 1970's to 2000? (totally over lacqered BBs!) Or, current Steinway Hammers ? (after the knowledge shift due to the Hamburg Techs wizing up the N.Y. techs in the factory)??? Each is a different entity with different original scales, sounds and hammers! We need to be definitive here I think.
Ballistol is available from Amazon or on e-bay or gun stores. It goes for between $9-11 per 6 oz spray can. The bulk oil does not work as well as the spray can. That is likely due to the solvents for propellant added to the spray can. At least that is my thought.
I think we need some real data concerning the difference between the stuff in the can and that which is in an aerosol can. Speculation really isn't a good thing imo.
Doug,
Let's compare apples to apples. Kawai hammers do not, normally, have lacqer in them. They're just hydraulically pressed and are high density. Steinway and Baldwin piano hammers, traditionally have lacqer in them. Two different issues with two different remedies imo.
Best,
Joe To view this discussion on the web visit https://groups.google.com/d/msgid/pianotech/CAGXuAraG4BT6nQu7ACa2YKfWYmb5Ht7SNgc770G_ug8dM309tQ%40mail.gmail.com.

I am just about running out of M.E.K. and went to both Lowe's and Home Depot and only found M.E.K. Substitute. When I see something that says "Substitute", it usually means I have to pay more for something that doesn't work nearly as well. I did not buy it!Where do I get the real stuff?Regi

Here is a recording of that Baldwin SD10 after I washed out the lacquer from the hammers. I ended up having to voice it back up a little in the bass and tenor section using B72. Overall, I'm happy with the results and although I would have liked to put a set of Ronsen hammers on this piano, I think the results are very similar.Regi
