I then painted this metal part, some sort of crank handle, and inserted it into a cog piece that is glued to the base against the rear middle section. Those who have experience of these cable cars might know what it is... (my guess is some sort of coupling crank?)

Then I reached a point where the build failed me a little. Reading the one other build report/review on the internet for this thing, it seems I was not alone...

At the rear of the Powell Street cable cars is a trellis-style retractable barrier. Seen here indicated by my rather obvious arrow:
San-Francisco-Cable-Car2.jpg

These parts go to making up the trellis barrier. Nice, except those brass rods will need straightening, some brass strips will require shortening. That's pretty straight forward now and 'run of the mill' stuff having got so far into the build.
20200602_210728.jpg

The strips are prepared, some cut to shorter lengths. No problems here, I'm ready to assemble the trellis.
20200529_134152.jpg

For rivets, and to ensure movement of the barrier once assembled, Artesania Latina provide brass 'rivets' The theory is the 'rivet' is passed through the two pieces, as here, and then crimped using pliers to form a rivet. Seems pretty logical.

Nine attempts in, one okay, one that fell out after this photo, and seven complete failures.

Rivets need to be malleable by nature. It's important that the rivet is of a softer material than the substance it is securing. The problem here is that the brass rivets provided by the manufacturer have the appearance of short brass nails. Not only do they snap when compressed, they are stronger than the brass trips, causing bending and damage.

After hours of thinking, exploring and looking at my insufficient supply of brass 'rivets', I put this stage to one side, and continued with other aspects of the build. I have been unable to locate any 1 mm rivets that are suitable, or any jewelers/watchmaker nuts and bolts that may have worked in lieu of the supplied 'rivets'. I have since come up with a solution I think will work, which involve small sewing pins and jewelry making crimps. I will not be defeated by cheap or improper parts. Nothing to lose by trying, I'll revisit the trellis again soon. Stay tuned!

In the meantime, I've prepared the next stages of the build. These are metal decorative corners for the front section, and an arm rest for the shorter length seat:
20200602_210642.jpg

These boards will be attached to the sides of the cable car and painted black:
20200602_210612.jpg

This is construction for the steps at the rear of the cable car:
20200602_210455.jpg
20200602_210514.jpg

All of these parts have been primed and will be painted black soon.

Thanks for checking in again mates, I'm off now for a cuppa and a breather before trying out my trellis-making alternative plan. :relieved: :cool:

Joe, your rivet problem is not uncommon. Amongst us aircraft types rivet swelling softer material is always a consideration. In your case I could recommend making the little b*ggers out of copper wire. Much softer than brass and given just enough length to form a bucktail they should not bend or "toenail" on you, provided the clearance holes are of close tolerance. Hope this helps. Rick H.

Thanks Rick, I'll file that for reference in case my solution doesn't work as expected. I do have some electrical copper wire handy too. Thanks mate.

Some great work Joe, it's really coming together nicely, and looking very good. I hope you can sort the rivet problem out. Looking forward to the next update.

Just had a catch up on this. Great work so far on a really interesting build. Did you find out what the crank was for? I wondered if it was the mechanism used to grip the car on the cable, or the brake for when the cable was released when the car stopped?

Based on the older tramS in Brussels Tram museum, it is probably a brake for the rear wheels for use by the conductors on steep hills.

There is only one crewman aboard these little vehicles and that would be the "gripman" or cable car operator. He uses the grip lever (located between the opposing bench seats up front) to engage the cable (which is moving under ground) to get the car going. I have watched these guys operate these cars but never paid any attention as to how they stopped them, other than releasing the grip lever. As to the crank on the rear of the car platform....never seen it used that I can recall. UPDATE ALERT ! SWMBO (a former Bay Area Native) has just informed me that there were actually 2 crew members and the second one acted as Brakeman/Conductor and he rode on the rear platform. Never saw him as he was blocked by the closed compartment and the crowd of people standing at the rear of the car. Sorry for the confusion. Rick H.

Great, Thanks for the clarification Rick. I knew you might know, or in this case, SWMBO :smiling3:

I cracked on with things, but not as much time lately as I got stuck in Australia which caused more than a few issues on return home. All those things you saw earlier were painted black:
20200608_135528.jpg

I created the arm rest for the front right passenger seat:
20200608_140017.jpg

And glued it to the seat after a varnish job:
20200609_164846.jpg

Next, the painted decorative metal corner parts (unsure what you would call these things, sort of what we here in NZ might describe as a 'Colonial look') were set into place. Some required resizing with a file, others just a light sanding to fit.

Next up was a handle, and latch and bolt for the front door. Very tiny parts as you can see here next to this standard Humbrol 14ml tinlet
20200609_172517.jpg

Handle, latch, and bolt mechanism installed:
20200609_174144.jpg

Frustratingly the U bracket into which the bolt slides was a bit tight and so the mechanism doesn't open freely. That could have been my fault. But the door remains closed and still opens so at least it's functional.

The black step boxes and side bottoms painted earlier were brought together and the rubber mat installed into the steps.

The steps are approaching the mechanical mechanisms for the underside, which I'm looking forward to. In the meantime, the last fiddly bits of the upper car body construction, except the roof, are the side boards for the open section of the cable car. You can see them where the folks are hanging on for dear life here
Strip_photo_1s.jpg

The two lengths for each step are laser cut parts, the smaller vertical pieces are measured and cut to size. The instructions call for them to be painted white with a black strip (presumable a non-slip strip) along the front edge. The photos I have show them all to be what appears to be light grey. Maybe they are just dirty or off-white. I'll go for the white anyway with the vertical pieces painted the same blue shade as the body onto which they connect, as you can see between the peoples legs in the picture above.
20200707_155032.jpg

While the primer is drying on the side boards in preparation for the white, I revisited the trellis barrier. I said I would not be defeated. So I tried the sewing pins and crimps. No success there wither, the crimps wouldn't stay in place. So I went online, and after a bit of thought I altered my search from jewelers or watchmakers nuts and bolts or rivets, to 'glasses repair kit'.

I basically went nuclear. 1,000 pieces, various sized tiny bolts and nuts, washers, screws. A combination of nuts and the bolts worked! A less than NZ$10 fix. And what's even better, is I can now repair my glasses at home :nerd:
20200715_171921.jpg

I did however, have to drill out an extra .5mm for every single hole for the bolts to fit. Laborious, but using an (overkill) electric drill made it easier and faster using a polystyrene box lid as a base. The nut heads are subtle, you'd struggle to notice that they aren't rivet heads unless you went looking. The nuts not so subtle, but they'll be partly hidden.
20200715_172000.jpg
20200715_171932.jpg

I built up the required shape with the lengths I cut to size earlier on. It was useful to size the screen diagram to the same scale as the actual item. I left the only successful rivet in the lower left joint. It would casue more damage then it's worth to take out and replace.
20200715_184101.jpg

Three rings were placed onto the opening/closing side of the trellis barrier, and the other pole was inserted into the 'fixed'side. As you can see, the barrier is functional. Two brackets will secure the fixed pole to the cable car cabin wall, the other will extend to a closed position and sit in two hook latches which will be attached to the white cable car pole at that end.
20200716_131150.jpg
20200716_131137.jpg

There is one negative to using nuts and bolts in this construction. The more you exercise the trellis, the bolts tend to loosen off. A few have even detached over (much) repeated use. But I'll be setting the trellis at a favourite position and securing the bolts in situ. It can still operate, but as it's not a toy I'm not fussed about a permanent solution to the bolt loosening issue. After the fight I've had with it I'm content to continue as is.

Next update will be in a little while again. We'll be attaching the trellis barrier, those side boards, painting and attaching the various control levers, and beginning construction of the lower mechanical bits and bobs (running gear/undercarriage?).

Bye for now, thanks for looking in again. Hoping you are all well and safe.
