Efferman's Custom Parts

[rm8]

pleas look here

the McPherson part. you need the dark grey wheelholder part of 42000 steering hub, the outside and the spring of a big shock absorber to complete it

it should work, but i give no guarantee till i have built the 3 pin part

Dont know the strength of plastic they use, but I thing ball for joint for arm is the weakest point of this cool part. May be is better to make pin hole or axle hole for original LEGO axle/pin ball joint? And axle hole for steering arm should can be placed higher.

This is just my thoughts..

Effe, could you make small racing wheel (43 mm) with "normal" universal car design for sportcars, offroaders and trucks (not for front loader) and "right offset" for 6 pinhole and axle mounting. Thanks.

Guys, did someone received something except wheel covers? I want to know rigidity of material. Shipping to Russia is slow and expensive, so I want to make big order, but dont know how useful this first versions of parts, especilall functionally (not decorative).

racing wheel small replacements will be done

to the mc pherson part, i have tried it with a pinhole, but this would end in a conflict between pin and the dark bluish gray wheelholder. and i think this should be stable enough

the pin arms to the top and bottom balls at this part are longer and they are really strong enough

edit:

egor, the offset of the racing wheel small replacement, can not be much bigger when the 42000 steering hub is used. a half stud more and suspension parts can collide with the rim. i will do the maximum with the new 42021 suspension arms

Thank you. Cant wait to order and make review of "custom parts by Effe"

:)

[efferman]

first a 6 spoke rim with zero offset. this results in attachment points exaktly in center of the rim.

and the truck rim in racing wheel small size. same offset

Should I choose polished plastic for functional parts like cv joints, steering arms, or it does not play role (from the point of friction)? Or grainy is functionally the same?

to narrow so it needs some tweaking

What do you mean narrow? Can I buy it, or it is raw?

Edited April 9, 2014 by rm8

[efferman]

The surface is even with the polished option a little bit grainy. So you can choose the cheaper option. Pin holes have to cleaned with a 4,8mm drill and crossaxle holes are a little bit gambling. Sometimes they fit, sometimes the need some pressure to fit the axle in.

Turntables need some rotations under pressure to spin smooth. And if rims are stable enough i can say in some days. I have ordered two of the unimog rims.

Edit

A newer version of this part is uploaded, but i will again take look that it is solid enough if you want order a bigger amount of it.

Please send me a pm with all the parts you want buy and i will tak a look of all.

not sure if this would work but i have designed a counterpart for the lego wormgear

theoretical with this, a 32m crossaxle and a lot of wormgears a very long actuator should be possible. any ideas to improve it?

[ritztoys]

Looks like a very useful part, what are the dimensions? This might fit inside a 2-stud wide space? Thanks efferman

[efferman]

the dimensions are 2x2x3 studs. the gap between two sides is one stud so a beam fits inside. but this part is really experimental and iam not sure if the wormgear works proper with it.

I'm not sure if it's possible, but a 4 studs long version could work with 2 linked crossaxles (with a 59443 or 6538), so you could have an even longer actuator since it won't be limited by the length of the crossaxle.

[ritztoys]

Please keep us builders updated on this part, would make boom extensions in cranes easier.

[efferman]

when i make a new order it will be part of it. actually i am waiting for two orders in height of 90 euros (including shipping)

bob, 4 studs long to jump over the two studs long gap of a crossaxle connector?

Yes exactly... But I found out that the axle connectors are wider than the thinner part of the worm gear

[efferman]

a beam with a integrated 4L gear rack. fits to 8 and 24 tooth gears

[Boxerlego]

I like the gear rack, maybe the liftarm could also be longer and have the gear rack centered on the liftarm.

[efferman]

Like the 7 and 13L gear rack?

Edited April 11, 2014 by efferman

[Boxerlego]

Yes.

[efferman]

No problem

edit:

done, gearrack 7L for 8 tooth gears

Edited April 11, 2014 by efferman

[Boxerlego]

The gearrack is on the wrong side of the lift arm. It should be on top.

I don't understand. Any side can really be the top.

[dhc6twinotter]

Efferman, you're doing an excellent job designing these. TLG should hire you as a parts designer.

[efferman]

thanks daniel

do you want the pinholes at the end of the rack on the side and not on top?

edit:

is it this what you want?

This looks great, but I'm a little worried that the material is too thin where the trough between two teeth is right above the axle hole.

[efferman]

A good point, i remove the holes.

[Boxerlego]

Nice work! I must say that the gearack is one of those tough parts to make because of the tolerances required on it. There is tons of potential behind a liftarm gearacks. Watch this video on the programmable drummer and think about using liftarm gear racks on it instead of the current studded method as was used.
