Hi all,
I've run out of options for good advise so I am turning to the internet for wisdom here - So I have purchased a rack - a mijnen pieper around front rack - pretty cool rack, I prefer its design to the Wald 137 I've been using the past year and its a bit bigger and better fit for what I need to carry. It came with this aluminum y mount bar, which is where my problems began.

Its great except my canti break cam is rubbing against the Y-bar mount system. Instead of just buying a new cam/ brake cable that would allow me to lower the straddle cable (not sure its actually called that?) I filed down the bolt hole down to give me the additional clearance so it would no longer rub, but i needed 1mm so I tried to bend the mount arm a bit - and because aluminum doesn't bend when cold, I wound up breaking the mount arm . (genius move!)

Any solutions or advice on basically getting a new mounting system to
a.) avoid buying new brake cables and all that,
b). fit this rack to the fork bridge hole (rather than the handlebars like a wald).
c.) not learn how to weld, learn new trades and buy 100s dollars worth of equipment and tools.
Would be highly appreciated.
Let me know your thoughts.
Thanks in advance!
I also would like to know if anyone else loves this bridge type as their favorite, this is my favorite because it just looks so cool. As a New Yorker my favorite is the Queensburo Bridge.
Does this game take into account compression and tension? I need to know as I'm looking to build a cantilever bridge over a moat near my base and the design might not work if this game doesn't use tension and compression in its building system.
Reaching out to the history buffs here. Out of all the styles of bridges available, why was a cantilever bridge design chosen for Story Bridge?
I've tried to research this particular question but I'm yet to find an answer.
It's clear that the final version of the original Bay Bridge (opened 1936) as a whole wasn't intended to carry heavy freight trains, as evidenced by the steep grades (for freight trains) of 3% on the West Span, 2.5% in the Yerba Buena Tunnel, 1.7894% on the deck trusses connecting the tunnel to the cantilever section, and 2.74% on the skyway section of the original East Span (demolished 2014-2017). It is also known that interurban EMUs (which can handle steeper grades) of the Key System, Sacramento Northern, and Southern Pacific Red Cars originally crossed the bridge. Here's the diagrams from Eric Fischer on Flickr showing the inclines: https://www.flickr.com/photos/walkingsf/5449244628/in/album-72157622139053795/ https://www.flickr.com/photos/walkingsf/4235063165/in/album-72157622139053795/
However, the grades on the cantilever arms and the west 2 of the 5 through trusses on the old East Span were only a gentle 1.3%. That is inline with with the gradients of other high-level railroad bridges/tunnels that carry freight, such as the Hell Gate Bridge with 1.218%, Eads Bridge with 1.5%, Huey P. Long Bridge (Jefferson Parish) with 1.25%, Quebec Bridge with 1.23%, and Seikan Tunnel with 1.2%.
Was the design of the original San Francisco-Oakland Bay Bridge changed early on after construction had started? That's especially considering that semi-trailer trucks had started appearing right when the original Bay Bridge started construction in 1933.

Any solutions or advice on basically getting a new mounting system that would support the following criteria:
a.) avoid buying new brake cables and all that or switch to V brakes
b). fit this rack to the fork bridge hole (rather than the handlebars like a wald basket).
c.) not learn how to weld, learn new trades and buy 100s dollars worth of equipment and tools.
d.)
