That 8/12 portal axle could be really useful.

How about this part, but with 5, 7, or 9 pinholes instead of one? Longer versions will be very useful for cross-bracing.

I've been following this thread with a lot of interest. Although I don't have much faith in 3d printed parts I would love to see you model these parts as I'm sure you would do a much better job of it than me .

The gears are possible, how much teeth have the clutch gears?

[allanp]

The clutch gears have 16, 18, 20, 22 and 24 teeth. The picture shows 2 gears with 24 teeth as one is for first gear and the other is for reverse. Feel free to alter/improve on these designs, the diff case in particular could look better.

I dont know if it is possible, but I would love a smaller and more compact diff.

As soon as I can I will order that portal hub for 62,4. Might be another month, but it looks perfect!

[efferman]

the 24 tooth clutch gear is done

you have had an idea for an more compact clutch. can you explain how this should work?

[allanp]

Very nice work . Oh I forgot to mention, to use the full set of clutch gears it would be very helpful to have a 10t and 14t standard or double bevel gear.

[efferman]

ok, but first a 20 tooth non bevel clutch gear and the link to the 24 tooth clutch gear

[allanp]

Fantastic. i wonder if shapeways has an option for a slightly flexible plastic for the leaf springs.

[jovel]

Why did you make that 20 tooth clutch gear non bevel?

A bevel version would be far more usable ( at least for me ).

[efferman]

jovel, because bevel gears are extremely complex to replicate and i think there is a use for non bevel gears in a gearbox

edit

i have a concept for a high torque diff with 4 12 tooth bevel gears as planet gears and two 20 tooth bevel gears as sun gears.

the center part holds the gears and one of the outer parts is part of the 36 tooth double bevel gear which drives the diff. the hole diff is 3 studs wide

What is the diameter?

tim

[efferman]

actually 32mm

[timslegos]

What is that in studs?

tim

[efferman]

4 studs, the diff will later fit in the 5x7 frame

[efferman]

the unimog rims are arrived. altough the walls are very thin they are stable enough. and the 8110 tires dont slip on them. pinholes need a 4,8mm drill and the axlehole need some polishing. the standard racing wheel medium looks with the wheel cover like the specialized rim

Hi effe,

those look great!!! How's the surface?

Pat

[efferman]

its like sandpaper and should be the same like your U406 wheelcovers

[Pat-Ard]

thanks, very nice :)

[efferman]

a short side by side with the 42000 steering hub in the unimog rim and racing wheel medium. the unimog rim is to deep for the lego portal hub

Oh man just imagine what would happen if Nicjasno got those rims on his hands

Nice work as always Effe!

[efferman]

i think he want more a sportcar rim with the diameter of the 8448 tires.

I was thinking about that, but couldn't figure out how to do it with existing spider gears.
