The best laid plans…

So as Martin and I were running around town shaking down the eMR2 the transmission went out.

There was a little jumpiness from the drivetrain creeping in earlier in the day but I figured it was due to the worn engine mounts.  Just before drive was lost the jumpiness was particularly bad but sometimes you just have to let something break to figure out what’s wrong.

Drive was lost taking off from a stop with a little pop and a zizzing, as if a spline was stripped, yet the transmission shifted OK.  None of the gears would work, simply producing the zizzing noise.  It’s hard to believe the coupler failed but it’s certainly possible.  The other possibilities include a stripped spline on the shafts or a catastrophic failure of the final drive.

So instead of videos of the car in action, I’ll have to entertain you with pictures of the transmission teardown when it happens in a week or two.

In other news, the bamboo/balsa frames for the velomobile came in and look beautiful but were built with the wrong thickness balsa core.  Recovery options are being conjured up.

The eMR2 runs again!

Though it came in a rather ratty looking box and none of the fasteners for the cover could be found, I scavenged enough screws to fasten the cover on the inverter and put it back into the engine compartment where it belongs.  It ran a bit inconsistently at first, something I racked up to some bubbles in the coolant that triggered amp limiting due to temperature but once that was worked out it ran like I remember it-almost.  I think I have to get a few cycles on the batteries to wake them up again.  They were left inactive for about 6 months fully charged, but nevertheless it’s still a shock to the system that will take a few cycles to absorb.

For some reason, power wasn’t getting to the front of the car so no headlights, wipers or vacuum brake assist.  In the process of disconnecting everything to diagnose the inverter problem there must be something yet to be hooked up.

Once everything’s buttoned up I’ll post some video.

Rally for the River 2008

Last Sunday the Jones Falls Watershed Association held its annual Rally for the River to draw attention to the health of the river that runs right through the middle of Baltimore City.

The Jones Falls powered Baltimore’s early industrial beginnings and as a consequence became a dumping grounds for all kinds of waste, both industrial and human, resulting in Baltimore leading the country in typhoid cases around the turn of the century.

The solution?  Bury the river!  In a prime example of employing the most elaborate and expensive solution to avoid solving a root problem, three tunnels were dug starting at what was then the northern end of town and chanelled the river underground until it empties into the harbor.  They typhoid problem did subside, but then the river remained just as polluted as it emerged into the Chesapeake Bay.

The river is actually hard to spot as it winds its way through the deep valley that’s shadowed by the shuttered mills and factories built more than a century ago, a strange development for a waterway that was so pivotal to the city’s beginnings.  The flip side is that following the river reveals some very quiet and secluded areas that make it hard to believe you’re still in the city.

This year the festivities included the closing of the northbound section of I-83, the freeway built on top of the tunnels that channels the river.  This affords a great opportunity to notice things that usually pass by too quickly when travelling by car.

In addition, that same day cyclocross races were being held in Druid Hill Park.  It was the first time I got to see a cyclocross event in person and it looked a lot more interesting and fun than roadracing.  Now I’m looking at adding yet another bike to the fleet.

Below are pictures from the day in chronological order.  Enjoy!
