Some years back before I bought the Atlas turntable, I built one from an Erector set that rolled on a circle of 027.

I remember Mike Kollosus (I think that was his name) had a variety of Erector bridges on his AmFlyer layout - quite a few years ago in that other magazine.

Has anyone here ever built any? Just curious.

Erector Sets were so cool.  I don't think I played with anything more when I was a kid.  

 

One thing I noted but never overtly acknowledged was that my parents loved me playing with it.  They thought it was learning, not playing (and they were right, in a way).  I caught on early to the fact that I could easily get a 1/2 hour extension of bed time curfew if I was actively playing with my erector set when the time came. 

 

Also: I don't know about you other folks, but I had a set where the small nuts and bolts just seemed to evaporate slowly, with predictable regularity.  Never could find them until you walked barefoot on the hardware floors!.  My dad picked up an extra  package of them at the hardware store from time to time.  .

You hit a home run when you acknowledged:"One thing I noted but never overtly acknowledgedwas tha my parents loved me playing with it. They thought it was learning.....".

I think a lot of us who frequent this forum are who we are in part because of the encouragement our parents gave by providing us toy trains and other developemental things such as Erector sets. Often this was a financial sacrifice as we all know these were expensive toys back in the day.

 

I worry about the current generation that derive their creative play by swipping a screen or clicking a mouse.

 

Nice post!

You can never have too many Erector sets or parts!

I would like more details about this lift bridge, as it looks a lot like the one I need to design and build for the entrance to my train room.

I agree......I had about every building toy made as a kid....including a plastic Erector like set that would work great in O scale as it was more 3-D look to it.

But all of us that built things constantly got a basic but real world lesson in engineering. I remember a buddy and I built a bridge from Kenner girder and panel set. It was for our HO trains. The bridge would collapse with each train we sent across....until we figured out how to build it and transfer the weight of the train. Basic but real world knowledge! 

I do give my grandkids Lego (and trains) in hopes they will not be 100% ignorant of basic building theories.

You're so right about those nuts and bolts.  Mine were always mysteriously vanishing into the fourth dimension.  Our floors were carpeted at that time, so I couldn't use the bare-foot method to locate them.

 

I don't think Dad ever did catch on that replacements could be found at the local hardware stores.  He probably believed that they had to be special-ordered from Gilbert.

 

By the way, am I the only one who ever foolishly got his finger caught in the gearbox of the electric motor?  It didn't do me any lasting harm, but it taught me a healthy respect for moving gears.

Oh man!  Now that . . . that is just way too cool for words!

You only do it once . . . I know that from experience.

Thank you for your interest Sinclair. If a picture is worth 1000 words, a video is worth 1000 pictures....go to 8:14 on the video linked here to see the bridge in action.
The towers are free standing and not connected in any way other than the moveable span. There are 2 Erector motors, the newer ones that have the gear train built into a transparent case, on the top of each tower.
They are directly connected to each other with a long driven shaft that has 6 Erector pulleys on it. The bridge has 6 "cables" on each end that are strung over the 6 pulleys on each tower. The cables loop over the driven pulleys, as well as 6 idler pulleys to help line things up, and are connected to counter weights within the towers. The weight of the bridge and the counter weights offset each other so the load seen by the motors is small.
I originally struggled with how to install limit switches to stop the bridge at its extremes but this looped cable system is flawless. The cables just slip when the bridge is all the way up or down. I operate the power to all 4 motors manually with one momentary-on DPDT (DC reversing) toggle switch.
Please let me know if you have any further questions and good luck with your project!

Wow!  Tonkanut, that's a great piece of work!

Rick C, Lee Willis & AMC Dave: You're right about the building toys from when we were kids. I was sick one whole summer around 62, and those plus the REMCO science kits kept me from dwelling on it too much.

It's a real loss for kids not to have things like that. Even LEGOs seem designed to build only one thing, instead of multiple structures.

Anybody have more bridges?

It'll probably be a while before I get to it, but thanks for the video link.  It solves another problem I was looking at, how to keep the trains from going off of the edge, the counter weight is in the way, very nice.

Great thread!  I can remember my brother & I with our shared 4 x 8 layout back in the 60's. He had O-27 oval around the sides and I had a O-27 figure 8 inside his track. We didn't have real buildings so we made buildings, tunnels,  & accessories with Erector Sets, Lincoln Logs, Super City, blocks of wood, or even cardboard.  We had to be able to pick up everything, only the track was fastened to the board.  We played with it in the living room but the board was stored on its side in  our bedroom. Thanks for the memories!
