#135 ~ Precision Instrument

 Trolley Poles and Hold Down Hooks

Fabricating some trolley pole hold down hooks.

Last time I already installed the trolley pole bushings but then I goofed and installed the weights before installing the trolley pole hold down hooks.  

But looking at the prototype hold down hooks, I may have not goofed at all! I think I can work with this.

For the Trolley Poles I used Miniatures by Eric Traditional Trolley Poles HTP4.

The hold down hooks are fabricated using some .015x.042 Brass Flat Bar from Detail Associates.

The hold down hooks need to be at a height so that the trolley poles are horizontal when in the stowed position.

The .015x.042 brass bars slipped between the roof and running boards nice and snug.  A little epoxy will hold them in place.

I think I got the angle just right!  I painted the hold down hooks black and glued them in.

Ooh! Nice!  #135 is looking like the precision instrument that its meant to be!

Yes sir!
The precision instrument its meant to be!

#135 ~ Weights & Measures

 Heavy Models Make For Good Electrical Contact With The Rails.

Since the Weights are Big- Now is a Good Time to Figure Out Where They Should Go...

...before adding interior lighting and threading the wires everywhere.


The ceiling of the car seems to be the most logical place for the decoder and weights since the floor is full of motor and power trucks and interior details. 

Since the weights have to fit between the car ends and trolley pole bushings- Now is a good time to install the bushings so I can determine just how many weights I can fit there.

The bushings were tinned with solder before adding the weights, being sure to use a heatsink so as not to melt the plastic.

The auto parts store is a great place to get 1/4 oz weights. I was able to fit 4 of these 1/4oz tire weights between the car end, pole bushing and above the windows.  And another 4 on the other end of the car, for a total of 2 ounces. I painted them black to help them not be so conspicuous. Because the roof is arched the weights won't lay flat. So I slathered the edges of the weights with hot glue and squished them into place.

Now you would think that while adding the pole bushing I would have also considered the pole hold-down hooks since they too penetrate the roof.  But no. I forgot. So now I gotta figure out how the add them with those big ol' weights glued in tight right where the hold-down hooks come through. But that will be for next time.

The weights are well hidden up in the tall roof and not so visible trackside.  And now the car has some nice heft to it.

Yes sir! Hefty!
