I don’t know about good, but at the time I was a mere 14 and living in Italy. Had no knowledge of harmonica players (per se) and did what I thought I could get away with to keep my chromatic running.
For breath savers I would use doubled slivers of recording tape (oxide side down), safety pins for springs, and thick discarded nail polish for glue. I soaked the wood combs in a 50/50 mixture of Noxema
and baby oil..later switched to mineral oil, replaced buttons with real buttons, rounded corners, and Simonized (a car wax) the cover plates and mouthpieces. I don’t claim to be the first, as this sort of thing
is more or less just common sense. But when you don’t have any access to outside influences, you make your own.
> What you are suggesting is that I compress the spring to change the equilibrium position of the spring. In the new equilibrium configuration the displacement from equilibrium will be smaller (because there will be less initial compression) and therefore the force due to the spring will be decreased. Perfect!
Yes, that’s the ticket. A stock spring has to be almost fully depressed when fit into the retaining hole. At least on old 270 Hohner 48s. So, in effect you have already loaded the spring with tension. Then when
you actuate the spring, you are adding tension. The deal is to close the legs of the spring a bit so that the ’starting’ point for the tension is altered and then when you force the spring into the retaining hole, there
is less tension from the start. In this way, when you add tension by actuating the slide, you are already starting with less tension. So, the ultimate result is less tension.
> Hmm ... A small point, but I wonder how much the spring constant will change by changing the equilibrium point. I would think that this probably won't be much of a concern.
No, it won’t be of much concern to most people. Chromatics are designed (as much of the world is) to the 7/8ths ‘rule’? In other words, 7 out of 8 people fall into a group that one could call average. Like for
example, a male is 5’ 10 1/2”, 176.5 lbs on the average. And males on either side of this by an inch or two or 5 or 10 lbs would be considered average. So back to design. Most products are designed for the
average person. People whom are larger, smaller, heavier, lighter might be considered to be the 1 in 8 whom aren’t average. Example: A man (or woman) well over 6 feet tall may have trouble driving around
in a Fiat 500 or small sports car.
Conclusion? A chromatic will fill the bill for almost everyone. But a discerning experienced player may find them lacking in some areas. Therefore we have custom made chromos., premium grade chromos. etc.
I actually like the lighter feel of a safety pin. There is less of a chance to push the button and NOT bottom the slide out and therefore catch a piece of ‘another’ note instead of a clean note. The only dilemma with
a softer slide action is that the slide parts have to be clean and smooth. I carry a small eyedropper sized plastic bottle of water, and one of alcohol. If my slide(s) get sluggish, I simple spritz them a tiny bit.

I’m not familiar with that spring but in the past springs were bare metal. At which time I used cadmium plated safety pins. Then springs went to cadmium or nickel plating (much better), and by that time I was using
chromed safety pins.The old springs would sometimes ‘rip’ at the eye, and that left you with 2 pieces of wire that looked like fish hooks. They always ripped obliquely (on an angle), were very very sharp. Especially
if the wire had been wound against the grain. I have never ever had a safety pin break. I now use the wife’s pins. They are for quilters.
