I'm aiming to go through the rail right at the top of where the strip of felt was glued down. The slots in the rail give me a nice little guide for the drill bit. The reason for the pin vise is that the chuck on my drill press can't clamp onto something as small as this drill bit.
Weighing just under 20 lbs., it is the perfect setup for piano mobility. It is equipped with 88 touch sensitive, semi-weighted, full-size keys in a lightweight, space saving design. I then inserted the pin vise into my drill press. The sleek, elegant design of the Artesia Performer is both eye-catching and practical for players in their beginning stages. To make the holes, I clamped a drill bit just slightly thicker than my spring tails into a pin vise. The advantage is that the second hole will allow me to pull the tails really tightly into the wood with a pair of pliers, and eliminates the need for the specialized "parallel indents" machine. Some piano manufacturers make spring rails that already have two holes per spring like this. The modification that I mentioned earlier involves drilling an extra hole for each spring through the spring rail. The measurement you need is from the coil to the end of the curvy part. My piano is a console, so I bought the "spinet" length springs. There are several different lengths of these springs, so make sure you buy the correct length for your piano. This will cause missed strikes during which a key will be pressed, but no sound will be produced. If they are broken or disengaged, the hammers will not consistently return after striking. Their function is to assist the hammer in falling back to its rest position after striking the string. These springs only exist in upright pianos (their role is fulfilled by gravity in grand pianos). It turned out that the only major problem with this piano was that nearly all of the hammer return springs had corroded and broken. This is probably the single most common issue that people come across in their pianos, not only because people lump several different symptoms under the label "sticky key", but also because there are probably over a dozen different issues that can cause a sticky key. This means that a key will produce a sound the first time it is struck, but will not sound with any following strikes. The only information that the former owner was able to give me was that there were some "sticky keys". We picked it up, brought it home, and I proceeded to tinker with it for a little while to find any problems. Overall, it was in really good shape and just too good of a deal to pass up. A neighbor was getting rid of this wonderful little Kohler Campbell console piano a few weeks ago.
