I have been objective to the standard part colour combinations from TLG for a few years now. This post is not a bashing of new greys or browns. Axles have always been black, so to friction pins. Many parts have always been produced in few colours. (...) (18 years ago, 19-Jul-06, to lugnet.technic, lugnet.color, lugnet.parts, FTX) !!

(...) Thank you very much for the detailed answer. I’m starting with foot pump (5$), and will search for electric compressor later on. Pressure limiter, as I understand, is a must. I also prefer 220V. With those two constraints the offering is very (...) (18 years ago, 18-Jul-06, to lugnet.technic)

Hello, Try splitting the engine and lego compressor into separate circuts. That way you don't use all your pressure on each switch. I split my six pump compressor and scissor lift into 2 circuts one for each switch and it dramatically increased (...) (18 years ago, 16-Jul-06, to lugnet.technic)

The other option is to use an air tank that you fill from the neighbourhood service station compressor, or your own, and regulate the pressure with a pressure regulating valve (PRV). It is also advisable to filter the air to remove any oil or other (...) (18 years ago, 15-Jul-06, to lugnet.technic)

(...) I have a car tyre air compressor with a variable pressure limiter, which is essential for LEGO pneumatics. It will nominally produce 250psi. I set the limiter to 20-25psi normally, perhaps 30psi for short periods. Note that you need a pressure (...) (18 years ago, 14-Jul-06, to lugnet.technic)

I keep it in the west part of Europe ;-) Best regards, Dennis (18 years ago, 10-Jul-06, to lugnet.modelteam, lugnet.technic, FTX)

(...) The first compressor (250-300 psi) is too powerful, unless you can put a regulator or pressure reducing valve on it. 20-30 psi is probably ideal. See this old thread: (URL) (18 years ago, 9-Jul-06, to lugnet.technic)
