Default I built a tank bridge. (The movie)

I think I went and built a scale bridge too far. It is a scale 100 foot span, over a live stream, with a scale 16 foot wide roadway. It spans a scale “canyon” too steep for scale RC tanks to cross. It is the only stream crossing for over a scale mile in each direction. I think I’ve gone scale crazy.

Really, it just spans an irrigation ditch in a vacant lot full of weeds. It is strong enough for a person to walk across, because it is built of leftover materials from a home remodel. It is weatherproof enough that I will leave it out all winter.

For the techno dudes who want specs… it is made from a laminated wood beam and plastic decking. (An 11 7/8” LVL and TREX decking) Its 16 ˝” outside to outside and 79” long. The sides are held on with lag screws and deck screws. Its load limit is 380 lbs.

See for yourself.

Now I gotta ask after seeing so many of your videos. Do you drive by camera or just normally?


Looks great and real too!

Panther F... I drive normally, the camera just records movies.

edoubleaz... I know, down to 15 deg. F so far and it will get much colder soon. I thought about being there for your battle on Sat. but could not pull it off.

That's a really nice bridge, but it's too modern and well built. Whatcha need is a Bailey Bridge, You could build one this winter when you get snowed in. Or maybe a pontoon bridge for the spring snow melt and pond crossing.

Hi Rex
"That's a really nice bridge, but it's too modern and well built" - he's driving a Leopard 2 - a modern tank - so it's a perfect fit.
Besides a Bailey bridge is super fiddly with that skeletal framework, also not sure if it's capable of handling a 60 tonne Leopard?

Ya got me !!! I was too quick to post the photos of WW II Tanks on a basic Bailey. But I respectfully disagree that the Bailey bridges were flimsy when the skeleton sections were ganged up in multiple widths and heights. The really modern ones are rated at 80 tons, judging by the yellow load limit disk on the triple/triple bridge in one of the photos. I may build a model of one someday when I have a year or two available.



What tank is in the 2nd photo???

Hi Rex
Yes, after posting that, I googled Bailey bridges, found an interesting article which quoted weigth capacity as 10-100 tons - http://www.6thcorpscombatengineers.c...%20thierry.pdf- the Bailey Bridge by John A Thierry.
I didn't say flimsy, just fiddly, yep a spare year or two might suffice? Actually seem to recall Plastruct used to make bailey bridge like sections, but probably to the wrong scale.

A Bailey bridge can hold heavy loads. The State used a Bailey bridge to temporary detour traffic while they replaced the concrete bridge over the river in our town. I could hold two semi trucks at once. That had to be around 100 tons. It was up for over a year while they demo'ed the old bridge and built a new one.


Here is a Google Earth shot showing the Bailey bridge being built.

This bride is a strategic target. It must be protected.

YES! That's why I built it. My son and I have already spent a lot of time together going over strategy. Good father / son time.

When we set it in place I imagined it as a crossing of the Rhine... but now it looks more like Finland.


That's the scale "forest" I made the Leo and Panther tree smashing movies in. It's gone now, buried under snow.

That's funny, I'm a tank guy who is interested in RC airplanes.

The tank in the movie is a Tamiya Leopard 2A6. It is a smooth runner but I also built a custom camera mount with foam rubber and styrene outriggers for stability. It sits in the loaders hatch to give a crew members perspective.

Here are two other movies I did that are FPV. I have posted them here before.

As always, Paco, great stuff. I might have to copy some of your bridge technique, Pardner.

I have to come to Denver either this coming summer or the next and I think I might have to look you up for an afternoon of tank talk, if that's OK with you. I think it would be just great to see in person all these cool places where you make your videos. So if you're game I'll let you know when I'll be out there, and if you ever make it to Detroit and don't make a stop at my place I'll be HUGELY disappointed.

I know it looks close on a state map, but I'm a 5 hour drive from Denver in good weather. The entire Rocky Mountains are between me and Denver. I live much closer to Utah than Denver. Still, let me know and I could make the trip. We could get in touch with panzerpaul and meet at the FRAG battle field in Littleton, just south of Denver.

WOW! That's very cool. Is it a working drawbridge?

I have been looking at Bailey Bridge plans, Rex challenged me to scratch build one. If I do it right I could use it for battles outdoors and also a shelf to display tanks inside.
