Hi Jack and all,
From the photos of the model, it looks like the car cage is carried on 2 fixed cables and drawn across by a third cable. The 2 fixed cables supporting the cage would have been secured to nearby bedrock by large concrete blocks and not to the structure itself. There would have been a vertical component carried by the support towers inside each structure but the horizontal forces would be transferred to the surrounding bedrock by the concrete blocks attached to each end of each of the carrying cables. 

If one station is lower than the other then perhaps the cage could be returned to the lower station by gravity, towing the third haulage cable with it? Or there could be another cable attached to the other end of the cage with the haulage ropes rigged like a Main and Tail type incline as shown below. 
Substitute the coal skips in the diagram for the haulage cage in Bob's model. 

I hope that this explanation makes some sense,

Jack, I watched that model work at an NMRA convention about 30 or so years back. It was jaw-dropping and Bob won top honors for the effort. The towers were displayed on tables about 10 or so feet apart and the little cars went out & back. Maybe Bob can relate how he rigged it.

Woodie

Si,

Thanks so much for reposting the pics. Saw Jack's e-mail yesterday and couldn't find them either.

Jack,

The "cables" the carriage rides on are carpet thread. They pass through small eye hooks in the front of the interior trestle/rails the carriage rests on inside each house. The cables go along the rails before exiting out the building and into the mountain. You can see this in the pics of the birds eye view of the cable houses. On one side the cables tie onto eye hooks inside the mountains. On the other side they loop around a rod and attach to the frame with turnbuckles so I can tighten/loosen them. Bob

If any of you have back issues of the Narrow Gauge and Short Line Gazette, I had written a two part article on the model in the 2005 May/Jun and Jul/Aug issues. Had some history on the cable car crossing and the model.

Wanted to let you know that the model is still in good shape. Every once in a while I run the cable car back and forth just to make sure it still works. Hard to believe the model is almost 45 years old. Yipes !!!!

Bob:

Your modeling back then is outstanding even in today's standards! I was going to build the cable way also and obtained a set of Russ Simpson's plans for the Mich. Calif. cable towers but what stopped me was that I couldn't figure out how I could keep the strain of the cables from pulling the towers apart.
What would be nice if it would be possible to take a movie of the cable way in operation and share it here on Freerails.
I have the DVD movie of the prototype in operation but the black and white film quality isn't that good but it is better than nothing!
Some years ago someone hiked to the area where the cable towers once stood and shared a few shots of what was left which wasn't that much. It is more than likely so grown over now that it would be almost impossible to find today.
Yes, it is hard to find models that still exist after almost a half century. A local modeler, Lyle Spears still has all the logging modules that he wrote about in several issues of Model Railroader back in the 1960's. I have taken several pictures of his modeling efforts over the years and every now and then when he comes over for his monthly visit he will bring a model that he had just recently completed. Awhile back I had obtained two Bachmann O scale skidders(small loading engines)for him and he made large HO scale skidders out of them. He added one feature that I have never seen on a skidder model, reels of cable labeled on the end with the wire manufacture's logo. He gave me a copy of a page out of an early lumbering magazine about cable reels and I scanned the labels, cleaned them up and printed out labels on my Alps printer in HO and O scale, the scale ones for me and the HO for Lyle.
I have always wanted to model Lyle's first logging 18" x 6' diorama and upscale it to On30 scale in an area of 2' x 8'. I have scratch built the low 18" trestle for it and am about to start on the engine house copying the Cowlitz Chehalis & Cascade's engine house that was in Chehalis, WA. Lyle made a set of plans in HO for the engine house and gave me a set. You can see Lyle's first diorama in the December 1963 issue of Model Railroader.

John Garaty's diagram is exactly how the real cable system worked and the model. The south tower side of the car was pulled directly toward the tower. The north tower side was pulled by the "haul back" cable. It went through the north tower and did a 180 via two pulley towers. The cable then draped back across the valley and into the south tower. Not sure if the real cable wound around a drum and was continuous or in two separate pieces. The model uses two cables (black thread). As one reels in, the other reels out. The are oppositely wound on a single drum.

From what I recall reading, there was a 170 foot sag in the cable and the north tower was higher than the south. They used both to send the cars across letting gravity do some of the work. The loaded cars went in the "down" direction and the empty's were hauled up.

In the original 2 cable system with the steam winch, a round trip took about 15 minutes including pulling the loaded car off and putting an empty back on.

In the 4 cable system with the electric motors, a one way trip was said to be 108 seconds with the carriage going 20mph. Must have been a wild ride !!!

Jack,

Thanks for the kind words. Was in my early 20's when I built the diorama models. Could actually see without glasses and magnifiers :)

Took some liberty building the model. Combined the 2 cable system and carriage with the 4 wire towers and track. Its not exact, but gives the feel of the real system.

Funny thing happened at a convention. Had North and South Tower signs in front of each diorama. Each morning when I came into the contest room, the signs were switched. Finally a guy came by and said I had them backwards. Turned out to be Cliff Grandt. Told me he had ridden across on the carriage. Kept the signs that way from then on.

I have a few old photos of the Mich. Calif. cableway plus a short video of riding it. How do I upload all of this?
Thanks.

Hi Jack :wave:


Great to hear you have these photos & video.

The video is something which needs to be uploaded to 'YouTube' perhaps.

I'm not really able to advise you on how to do this.

'YouTube' obviously provide instructions on their Site, as to how to do this.

Once it has been uploaded to 'YouTube', the video can be Linked to here at Freerails.


- - - - - - -


The quickest & easiest way to upload photos to Freerails is by simply using the 'Attachment Button', at the bottom of the main Reply window.

The photos need to be 'resized' on your computer, to be 800-pixels wide, using what ever program you have for this, & must be less than 0.5 MegaBytes, which they will be at 800x--- size.

They can also be uploaded to your Members Gallery.

There are a number of different descriptions of how to do this in the 'Photo Posting' Forum, check 'em out.

If for any reason you have trouble, give us a shout in the 'Photo Posting' Forum, & we will see if we can guide you through it.

Once you know HOW, it is EASY, sometimes it takes a couple of goes to 'get it'.

If the photos don't come out right, we can always delete & re-Post them, so have a go & see.

As a last resort, you could eMail them to me at Freerails, & I could Post them for you.

Give it a go, can't wait to see them.

All the best.

Si.

Si:

I having problems in figuring out how to upload photos and the Mich. Calif. video It is a stand alone video and not a UTube video.
What is your email address and I will send the pictures and video to your directly and let you upload them.
Thanks.
