Where jig?

An American Cinematographer Magazine 1932 article mentions that the UFA studios in Germany used DeBrie cameras synchronised with Tobis optical sound recorders. Would have this been a motorised Parvo L? I am aware DeBrie later produced a version (late 1930s ???) that was a little larger and marketed it as a 'Silent' camera when shooting sound films.

this was cool. thx man!

I like how you skipped the part where you actually got the nuts loose. Which direction am I supposed to twist? Why are you using two wrenches? It would have been nice to explain any of that

Hello. Do you sell the 3d part, can i buy one from you pls?

About the tyres: I've discovered that lots of the "third party" manufactured tyres are slightly softer than the original Ninebot tyres and thus have a massively higher rolling resistance. With these my scooter struggles to keep up the speed even downhill. I have found that these "third party" tyre manufacturers varies in softness and thus the rolling resistance. The harder they are, the better they are. Sure I can buy original Ninebot tyres, but... no way in hell I'm paying $160 per tyre. ($320 for a set of two). NO WAY!

Did you make the astrolabe? Was it from a kit? Thanks for the lesson on how to use it!

please file for 3d printing

Where is the file for this?

what a nightmare of a job. Who's got time for this I'd rather buy a new scooter.

Very good explanation, but the whole video is somehow too dark or underexposed, what a pity!

Just going to buy a new scooter, way too much work for me. I’d get impatient, why on earth will ninebot make it this hard?!!

Orientation of tire's threads are matter for water puddles, only.

The covers you took off a wheel fork gotta be marked with right or left on inside of the cover.

Ale partyzantka stare klucze zero pojęcia

Thanks !!

Thanks Nate!

STL for the jig???

Great stuff. Man they sure improved the loading process with later cameras! I'm sure in the 1950's the "old timers" made fun of anyone complaining about loading. :-D

This is very cool. Bravo.

Hola buen video bro .si quisiera yo ponerle llanta de aire .se podría poner

Very nice. Well this work on the E25A models too?

just retread with a hot knife....or vice press.and put the hub into a freezer

Fascinating - so the Wilart actually came after the Bell and Howell 2709? I had a little experience with one of those decades ago and it was pretty quick and simple to load by comparison. The Wilart does look beautifully and robustly made though. Not sure I get the logic of the open/close light traps and split magazines although European cameras like the Debrie Parvo had internal separate magazines. Thanks so much for this!

What was the Torx BO key number you used to remove the motor?

Great video, the pix 240 is commonly used to record playback for the script supervisor even today, at least here in Sweden.

Hi, Thanks for the demo and the jig. I can't find the link to the .stl file though and would like to print one. Could you please provide the link.

Where did you get the tire from. I'm trying to find them online but they all have no reviews or negative reviews. Please help!

Thank you for making this really interesting and informative video about the Parvo, a lovely example. May I ask, in the center of the mechanism there appears to be a row of vertical rods or tubes, is this a remote lubricating system? My earlier example does not have this.

Great video about a classic camera. Nothing emphasizes how original French engineering can be like their movie cameras and their older Citroen cars. I've worked mostly with Arri and Mitchell cameras but I had had a little time with an Eclair Cameflex and more with Eclair ACL cameras and frankly they represent a redefinition from first principles of what a movie camera should be. A guy I knew decades ago in Australia had an Ernemann camera with a wooden case and brass mechanics with which he used to shoot stop-motion. Wonder if it was a Debrie clone, like the Askania appeared to be? Parvo comes from the Latin "small". I never quite understood why smallness was so important. I would not have liked to have been a camera assistant with one of these cameras with the awkward 3 side loading. The Bell and Howell 2709 and Mitchell Standard cameras with the classic "Mickey Mouse" ears magazines were more bulky, but the were so much simpler to load from the operator's side only - less handling, less risk of film damage and much more heavily built magazines. Also having the motor coupling right next to the critical focusing eyepiece looks awkward for the operator - maybe it had to be removed for ground glass viewing? I couldn't quite see how the pilot pins were actuated - the viewing tube appears to be in the way. Some beautiful footage was hot with Debrie cameras and their clones. Thanks for going to the effort of making this.

I liked the constrast between old and new technology. Great short !

Great video, thanks! Is it possible to load a standard 100ft bulk roll of 35mm film?

Need to replace tire

How do u take off wheel want screw driver ?

He could have printed a larger diameter one that will push the tire evenly when using the hammer.

So this must be the same procedure for the es3 as I read on Amazon where I just bought my tire from. And how long do these baby wheels last?

holy shit that's more work than i was expecting... not going to do these rolling burnouts anymore lol

Nice!

The jig is a great idea, but who has access to a 3D printer? If you have a roll of duct tape or two and a couple of hours, a tapered jig can be fashioned. Start out with a diameter of duct tape roll slightly smaller than the inner diameter of the tire. Build up layers of duct tape in ~ 10 - 15 mm strips until a taper is generated that ends up the diameter of the metal rim. Cover at the end with a single piece of tape for smoothness. You'll need to cut out wedges from this piece to make it lie flat. Warm the tire up, then place dish soap on the tire and jig. Push the tire onto the jig, pound with rubber hammer as shown by Nate and the tire will be on. I just now did it for a Ninebot ES4 front tire. It really worked well. ForestDweller

Dalle mie parti questo lo chiamiamo lavoro di bassa macelleria .

Great, but how to change the rear tire?

dit you avec number from front bearing plz ?

Any idea if this will work for the ES3?

Please take note that you need to use security torx for the 5 screws on the rim, super annoying to find out during the repair.. Anyway, thx for the video and the model, looking forward to try out the jig.. Made it with 20% infill and 4 wall lines, hopefully it won't snap :)

Great Idea, Thank you for your sharing video.Where can I buy jig ?

Hey, I'd love to print this out and use this but when I upload the file to Proto Labs for a quote, I have no idea what dimension unit I should use... it offers to print this thing in mm, cm, in, etc, but each selection keeps the default number of "units" (example: X: 50.000 in/mm/cm Y: 149.995 in/cm/mm Z: 149.989 in/cm/mm. I definitely don't want to build this thing to the wrong scale, so I'd like to ask you what units did you design this thing to be printed with? I can't find any specs in the README file or the zip folder. Posted this comment to MakerBot as well. Thanks for sharing.

Great job, thanks for sharing👍🏼👍🏼

Where is the file?

Here is .stl file : www.thingiverse.com/thing:4191167/files
