9391 Pneumatic MOD

Last week the new Technic Sets arrived at the market and I was curious about the new turntable on the 9391. After finishing the construction, I immediately  began to mod.

I'm a huge fan of LEGO® pneumatics, so the crane has to be lifted by small Pneumatic Cylinders (x189c01). A Small Pump (x191c01) is used in combination with a Technic Engine Crankshaft (2853) in order to achieve a 1L displacement.

Here is the result:

Small Pump in the middle, two Small Cylinders and the Switch 

A 20T meshes with a 12T, so less turns on the crank are needed

Crankshaft with only 1/2L to use the space efficiently

I also made two videos of the pump turning and lifting the boom.

More detailed pictures to be found on Brickshelf.
You can also download the LDD-File directly.

With best regards,

How things start

Good day everyone,

This blog starts as one of my New Year's resolutions for 2012.

I started building LEGO^® Technic again one year ago and had my difficulties with the techniques in studless building. So, I spent days, weeks and months on websites, blogs and forums. I built a lot of new models and became quite familiar with it. I adopted some special techniques by several great LEGO^® builders such as studless pneumatic constructions.

I would like to motivate myself to finish projects and to share those ideas with you by showing you my work.

Best regards,

Jan
