Lego GBC Model 1 : Marble Pump

[LegoGBC]

Hello!

This is the first GBC model out of 4 (or 5,if ill have enough pieces left for it) that ill pe posting soon.

This is a marble pump,but this one has a different mech than most of the pumps on youtube have.

Its very reliable and can go in very high speeds without jamming. however after some tests I decided that this speed is the best for me.

The mechnaism is deadly simple,its 2 beams (32056) spinning. one is elevating the balls and the other keeps the row from falling when a ball is getting inside (its hard to explain

in words,you should watch the video :) )

The Video:

Inspired by Jackal82JPN's mini pump.

EDIT: im making LDD instructions right now.

Looks great - simple and effective.

It is a very simple (and my experience says that the simpler the better), but I can't from the video see how the pump makes room for new balls to get in. Do you have some good closeups of how a ball gets into the system of this marvelous little machine?

Nice ans simple that, looks good as well with the windows so you can see the ball popping up

Nice contraption!

[LegoGBC]

Thanks everybody.

Lasse D : its very simple. look at the whole video,there are some shots showing it without the ball tower. if you need more footage than that

let me know and ill film some and send you.

So the rotating L-piece pushes the stack up, allowing a new ball to get in and that's it? My attempts at this design never yielded reliability, so you must clearly have found just the right angles, gaps and parts.

Well,first I noticed that the ramp piece (white) cant be 1X3 but only 1X4. ummm I dont know what else I can explain,ill take some pics and edit this post.

EDIT:
