Efferman's Custom Parts

[Zerobricks]

Can you make a 1 stud long U joints with 2L axles? Like the CV you posted but U joint sytle.

[efferman]

It is possible to design, but iam not sure if it is possible to assemble, because the center part will be very short and stable and hard to put on the central cross

[stefan_betula_pendula]

Hi efferman, it is possible to design the part 62531 in blue with a smooth finish?

[efferman]

The blue of shapeways fits unfortunately not to the boss blue and not to the standard technic blue. And for the wrong colour printed parts are very expensive.

[T_Tank]

well if possible the female cv connector with a 1 stud axle connector like this http://www.bricklink.com/catalogItem.asp?P=6538c

[efferman]

here it is, only in unpolished white because the pieces are maybe to small for the polishing machine

and the alternate universal joint

think you can combine this http://www.bricklink...tem.asp?P=92906 with that http://www.bricklink...tem.asp?P=6538c? but only for 1 studs worth of axle inside?

Also... thinking about the rc motor but it needs a REAL rc motor like a 240-380 can sized motor compared to the rather small one inside.. Would need to have internal gears that are a gear pitch common in the rc hobby world..

240motors are 24mm in diameter

380 are 38mm in diameter

bolt patterns if memory serves me right are 12mm and 14mm spacing from hole to hole on the motors

[efferman]

the cv joint part is no problem.

and the other part, you want simply a motormount or a motormount with a gearbox?

[T_Tank]

Was thinking a gearbox of some kind similar to how the buggy motor is but with a larger motor on the end I'd go with the 24mm sized motor to start with http://i00.i.aliimg.com/img/pb/067/527/333/333527067_338.JPG which would use a 48p gear. For meshing I'd go with something that allows one side of the motor to slide further into or off of the spur gear.

At least 3 to 4 gears should be used in the gear box not including the pinion gear so we can have enough clearance to run a axle under the 24mm diameter from the output of the gear box. also might need to throw some metal into the mix in the form of bushings or bearings of some kind in metric

Hope this isn't to much to ask for

[efferman]

i think the gearbox for a motor like this is a bit to much for my abilitys in making gears. Ozshan has me contacted that the helical gears of the torsen diff not work under load

[Bzroom]

Keep up the good work Efferman!

[T_Tank]

I got the front axle in will take some photos when I have a chance its temp mounted into the front of my mini mog the round holes are a bit tight though thats bit due to the unfinished material.

[efferman]

new parts are arrived. the wormgear counterpart is unfortunately not working. after one rotation of the wormgear it will be blocked through the counterpart.

but the helical gears are working smooth

the non steered portal axle part in black

and the rims and wheelcovers for my U 530

[jesse66058]

Outstanding job as usual!

If the helical gears are working, why does the Torsen diff not work? I just love out of the box parts!

I was wondering, could you combine http://www.bricklink.com/catalogItem.asp?P=99009 with http://www.bricklink.com/catalogItem.asp?P=92909 just like Nicjasno's Ultimate Wheelhub? Would the Nylon surface be smooth enough to work?

[efferman]

the torsen dif has different helical gears to make i smaller.

@ nijcasnos ultimate hub

i have no unassembled small turntable and you know how hard it is to disassemble it. and so i think i make a complete new one.

[efferman]

the requested cv joint

and a set of coil springs. uncompressed they have a length of 5 studs. the strength of the wire is 2,5mm. how much load they can take, has to be tested

edit:

and a set of smaller torque balls

[T_Tank]

been working on my mini mog today with that new front axle I had to redo the front suspension but needed to anyways but here some pic links of the axle mounted! https://lh6.googleus...0530_171508.jpg

Those mini cv's look awesome by the way!

[efferman]

thanks for the pictures! how good, or bad, works the steering rack? and hows the stability of the axle?

[T_Tank]

the gear rack works like a charm! as for the stability with how its mounted now I have some nice articulation (if i had softer springs equipped) compared to how the stock one. Now just figuring out how to send power to the gear rack since there is no room to mount the motor directly so using a few 16t gears in the pass through an none pass through! Also there is some flexibility to the axle but nothing bad at all once its all put together.

[efferman]

nice to hear that it works good

[efferman]

a new connector with a 45 dgrees displacement between the cross axles, to align the axles after a 12/20 tooth combination. i see this as a useful piece in steering mechansism which wörks with a servo

[efferman]

a question, does a clip with stud allready exist?

[SNIPE]

Love the helical gears I was just about to ask actually but then I saw this :P

[TheItalianBrick]

Efferman which software do you use for modelling? Is it Catia V5?

[efferman]

no it is autodesk inventor 2011
