a 18$ Huco L-Gearbox
Gearbox: http://www.huco.com/products.asp?cat=162

and 10$ for two BaneBots wheels and hubs
Wheels: http://www.robotshop.com/eu/banebots-04in-05hex-wheels-8.html
Hubs: http://www.robotshop.com/eu/hex-hub-s40-4mm-1wide.html




They seem to be almost exact same parts used by Ikan?!

Did anyone try to build one already?

I'd like to try myself but I can't find similar parts in Europe, anyone has an idea/onlineshop where to get them in EU?


EDIT: I'm not sure but I think it has to be this wheel (one size bigger):

Thats awesome! Thanks man. I'll definitely look into making my own FF with this stuff in a couple months. On a spending fast right now. lol
 
How do you order from Huco directly? i dont see a way to actually buy it.
These pieces are perfect to combine with some other parts for my project but i just cant seem to buy the drive shaft....

Any help would be greatly appreciated
 
This may come accross as a stupid question.. But how exactly were you guys planning on mounting the gearbox? Is that a 1/4 20 screw tap on the bottom of the box or what did you guys have in mind? This has potential to become the next $50 follow focus. :)
 
Ive got two ideas for mounting

Either a power arm like this

(seen here http://cheesycam.com/ikan-friction-follow-focus-the-f3-review/)

or

use a method like this

If you look at the first link to the gear box you can see that it has two threaded holes right next to each drive shaft(M3 x .5 screws) . It may be possible to use these form mounting otherwise there are two more holes on the top of the gear box that may possibly have a thread cut into them to add another mounting screw there

Vitor? :)
The Huco gearbox must be quite good, Redrock seem to be also using it for their follow focus systems.

Yep, that's me.
I think indisystem.com is also using it in their system.
I going way abroad for a few weeks now so this project will have to wait for me... but when i get back I'm right on the job. Maybe we all can produce a good way to combine this pieces and produce a good DIY project.

Thanx all
 
"The Huco gearbox must be quite good,"


Not really, it has 0.2" of backlash. I'm hunting down another option as we speak, however it's looking like I'm making one.
 
Anybody have any luck finding the Huco gearbox anywhere in stock and for a reasonable price? I emailed Allied about it, but it appears that it's a special order and they charge $20 for the part, a $15 handling fee, and then shipping on top of that.

I keep seeing references to a measurement of backlash but i dont understand what that means?

Is it the amount of play in the gear or distance the outside gear must be turned before the inside gear responds?

Thanks for the info
 
I've just ordered the gearbox (In stock from a dutch retailer).... now im just unsure about which wheel,s and in particular which diameters to get?
 
Wild, can you give a link to the shop where you bought the gearbox?
I haven't found a european shop where you can buy those robot wheels, I guess 1.875 Inch / almost 5 cm should be a good size. You should check the gearbox and see what maximum diameter it allows to mount before the wheels touch each other, and then see what size would feel best for your hand to operate as the smaller the diameter, the more you'll have to twist your wrist.
If you find any other kind of wheel that fits to your gearbox they might work as well. Put cheap, wide rubber bands around your lenses for better grip and if the wheels are plain you can attach anti slip tape to them.
something like this:
