JARAS TOOLS FOR PRECISION CRAFTSMEN
From installing key buttons to regulating grand pianos to hanging vertical piano hammers or leveling both white and black keys -
Tony Jaras has literally revolutionized the technology of the Piano Repair Industry. Over the last 30 years, thirteen inventions have
been developed that will undoubtedly secure a high place in piano repair history for Tony. Schaff is extremely proud to work with
Mr. Jaras and be able to exclusively distribute his exceptional line of tools. By using the best quality materials available, each Jaras
tool is designed to last a lifetime and enable the piano repair craftsman to do a more accurate job, as well as to save on
installation or regulation time. Any serious piano technician must consider owning several Jaras tools.
(A) String Height Gauge Attachment. Insert into either of
the two stands and by placing underneath the string an
accurate reading can be obtained from the ruler gauge.
(B) The let off rod is then replaced into the stand and set
for 1/16” lower than the string height reading. Now you
are ready for let off regulating.
(C) Backcheck Gauge Attachment. Insert into stand like
string height gauge attachment and set at the same reading
(shown in insert). The bottom of the bent rod will be 5/8”
from the strings. When the hammer is the same height as
the bottom of the rod, the backcheck will be properly set.
(D) Damper Lever Height Gauge. Insert into the base of
the stand and set the top of the extended part of the gauge
under the damper lever. This measurement should be
made when the hammers are half-way elevated or keys
half-way depressed.
