Veritical Hitches

[David Love]

What about the struts?  Does it add any stress there?  I have an older
Steinway in the shop and the bridge is so darn low (about 23 mm in the
treble) that I'm considering both raising the plate by installing a thicker
pinblock plus I might have to take a bit off the underside of the uppermost
strut where the bridge crosses under (a couple of mm's) to get the bridge
height up and still have clearance.  Is that likely to create a structural
weakness?

On the iron between the pins. That's why I rearrange the 
original in line hitch pattern and stagger them rather than 
leave the "break here" perf. It weakens the plate less.
