Post Monorail Dolly - Now with footage!
Previous post was lost in the great forum crash of '10.

Here's my dolly that many of you have already seen tidbits of:

Here is the current incarnation using the meade 492 motor kit:

I'm finding that the V-wheel setup just doesn't cut it for stability. I will try tightening up the assembly and see if that helps, but I think I may have to start over, or retrofit it with some wheels that cover a little more surface area. If you look closely in the video below you can see it wobbles all over the place. I also plan on upgrading the motor in the future to some sort of openmoco setup, but I'll wait for that to get fleshed out. Anyway, heres some stuff I shot the other day:

I love the length though! Two thumbs up Andrew. I love the custom connection bars. Beautiful work as usual.

A POX on you and your machining skills!

Yes, I'm just jealous.

That thing looks nice.

really nice work! I like the reduced encumbrance and the easy transportability.
what about the energy? where did you put the battery?

Nice machining? Love the self propelling dolly. This might even be adopted to a curved track given a suitable track platform be found.
How slow can you get the dolly to travel? 1h/1'?

The dolly is currently 9 feet long (3x 3' sections), but I can make more 3' sections if needed. The battery for the meade unit is just a 10-AA holder and sits on top of the box. I definitely have too many wires going on, but it's not too bad. The slowest I've run it is 9 feet in 40 minutes. I'm sure it can go slower, but I haven't tried. The tulip shots were all 9 feet in 20 mins. Everything (minus the camera) fits in a bag from a folding camp chair, and one small camera bag. I'm getting more familiar with it, and can now set it up in about 5-8 minutes. I will probably be another month or two before I can take the box back to work and start tearing into it again to tighten things up, but in the meantime I'll keep using it as it.

Would it be possible for you to take a few more shots of the rail attachment/head that the camera travels on without all of the cable and things? This is something I am currently working on and I would like to try your idea. I already have many of the items in your pics, just need some closer and more varied shots of the actual head.

That is IF you would be willing to share.

Great work!

Hey, this one is really great. Would you build a small range of this monorail?

Greetings André

That´s interesting too: http://www.bahr-modultechnik.de/DE/Prod ... L_ohne.php
