Title: B&W Negatives Found in the Attic.
Post by: Ken Hamilton on March 09, 2011, 07:35:38 PM

A major attic cleaning turned up a box of old photos & negatives I forgot I had.
Theses are a few scans of negatives of the On3 Tracklaying Machine under
construction from 1985....

Here's the underside, with working brakes. The turnbuckles are threaded;
the hinged journal box covers haven't been completed yet:

The tower under construction. The NBWs were made in a rubber mold:

This is a close-up of the can motor and gear & drum system that moved the
chain hoist back and forth under the swing arm. The gears also motivated the rods:

To give an idea how it turned out, here's a more recent photo of the finished platform.
The tool box isn't prototypical but I needed it to hide the motor:

Just for the record, here's another more recent photo of the model showing the chain fall
and cables. Basically, it's a continuous loop of thread that wraps around the drum a few
times, travels over the pulleys, then under the boom to the chain hoist trolley, which
runs back & forth along the boom.

If you guys don't mind, I'd like to play with the scanner a little more and post a few
more early negatives of this model. It's still one of my favorite Oldies.
Thanks for indulging my walk down Memory Lane.

Hey Ken,
As far as I'm concerned, you can stroll down memory lane all you want to, because sitting here on the porch and watching as you go by is most enjoyable.

I vote for more scans too. There are tons to learn there, Ken.
And when we're not in a learning mood, tons to enjoy too.

Wow that thing is great in so many ways! The subject to begin with and you cast your own NBW's, a man after my own heart!

More pics would be great!

Thanks....
Here are a couple more scans:
The ladder and the pivot point of the swing boom.......

(https://www.finescalerr.com/smf/proxy.php?request=http%3A%2F%2Fimages57.fotki.com%2Fv496%2Fphotos%2F1%2F15405%2F3206436%2FScan10154-vi.jpg&hash=5fd50062282e8af437b1a0c3900739daecaa9627)

The bumpers and the center-lock for the boom. A close look will reveal that some of
the NBW castings aren't the cleanest, but they weathered-up okay and went a long
way towards "Scratchbuilding" points!

And the working chain fall (watch gears & soldered brass) that travels under the boom....

(https://www.finescalerr.com/smf/proxy.php?request=http%3A%2F%2Fimages18.fotki.com%2Fv673%2Fphotos%2F1%2F15405%2F3206436%2FScan20017-vi.jpg&hash=d54db45f45821403de5c31f73dea1b8549f733d8)

That's all I've found.
Thanks for looking.
