Efferman's Custom Parts

[Hrafn]

here is an other point of view

Very nice! I think the axle might need to be a bit longer, though. If the hub connection is 1 stud thick where this axle goes through it, there might not be enough of the axle protruding on the other side for a wheel to stay on securely.

[efferman]

the crossaxle section is exactly one stud long. when two are placed together the center of the two balls are 5 studs away from its opponent. i have choosed this to make later a high torque diff.

dhc6, something like this?

[dhc6twinotter]

Yes, something like that would be perfect. I'm not sure how the steering would be done though. Perhaps the pin holes could be placed vertically instead? I think the ball should also be pointing either up or down to increase turning radius.

These are some really nice drawings you are creating.

thanks daniel

this position is for unsteered axles. rotoate it 90° and it is in position for steering

That is pretty damn brilliant actually!

That's clever

I've just gotten into Inventor myself (got a license for educational use), so I've gotten into my own parts modeling. I love the work you're doing, keep it up!

[efferman]

thanks, but putting the parts together is very hard

for example this

yes some parts dont sit on the right place

I see, that's really neat!

[Boxerlego]

Wow! You have a good collection of custom parts growing. Keep up the great work!

[weavil]

I will take a dozen of each!!! When can I send my first payment? LOL!!

[Zerobricks]

Here's an idea... A 15L beam with holes that go from all 4 sides...You can use half pins and pins to make cross section attachments.

[efferman]

something like this, only 15 studs long? i have made it that a beam can slide inside

If one fits inside, then that would change MOC's forever! Already got 12 uses for it right now!

[efferman]

wich uses are these?

btw, the turntable has arrived. very solid and uneven, so i hav to grind and polish a bit. the tooths of the gear hast to be grinded too, because the 8 tooth fits not perfect on it

[Alasdair Ryan]

That turntable looks quite rough.

Can you make a video when you get it sanded up to a better standard?

[efferman]

indeed, maybe the reason is that i have choosed the cheapest quality. A higher surface quality would cost roundabut 30 percent more. and yes i will make a video

edit:

now the frame is the limit and not the turntable

[timslegos]

I am glad you made it in real life! If you were to get the cost down, I would love to buy one. Also, would you be able to a turntable with a locking feature like that on the same scale as the current turntable? That way there would be a strong turntable for smaller creations too.

[efferman]

i think many afols would buy one if it would be cheaper. With 61 euro including tax and shipping it is pretty expensive. but i think without mass production in a mold it will stay expensive.

a smaller turntable with this stability should be possible, but i have to think how.

the files in .stp and .stl will come tomorow

here are the files if you want your own

to the smaller heavy duty turntable, can i make the gear only outside or inside too?

[timslegos]

I think it would be better on the outside. If you could only power it through the center and you could not also run cables and hoses through the center.

tim

[efferman]

ok, then i have one. the gap is neccessary for assembling. if a standard part prevents moving inwards this solution should be stable. opinions?

[Alasdair Ryan]

How about a slew spool valve for pneumatic fans?

(I bet Efferman does not know what one is...)

That is a reel not a valve...
