(...) Well, having only recently bought & built the truck the pneumatics are quite well designed. The finished model is let down a little by the crane arm which is quite crude compared to other parts of the truck design. Having said that the set (...) (24 years ago, 9-Aug-00, to lugnet.technic)

(...) I've still not built the 8462 I have yet (it is a personal bribe for getting to the halfway point in writing my thesis) but I think it looks pretty good, although perhaps a little on the large side for Technic figures. It cost 50 UKP from Busy (...) (24 years ago, 14-Aug-00, to lugnet.technic)

Jennifer, (...) So many adult Lego fanatics have done, or are doing PhDs! I'm at the same stage as you, writing up :-( Just a shame that I haven't got a Lego bribe to spur me on like you! And what IS the connection between doing a PhD and being (...) (24 years ago, 14-Aug-00, to lugnet.technic)

(...) From my own perspective, it is basically due to having an interest in how things work and/or making things work, a geek philosophy if you like. From this, making lego models and doing a PhD in a technical subject seem pretty consistent with (...) (24 years ago, 14-Aug-00, to lugnet.technic)

(...) Guess it was my tirade against the tanks you spotted:) I would absolutely love an airtank with reduction valves, btu as they are now, the tanks are little more than wide pieces of tubing, there will be no proper tank capacity without a (...) (24 years ago, 15-Aug-00, to lugnet.technic)

(...) Gotta learn to handle this tool one day:) Just had to add this: Using airtanks is not always a bad idea with compressors, when you only need a single or few pneumatics actions once in a while, the air tanks can be nice to have (ofcourse with (...) (24 years ago, 15-Aug-00, to lugnet.technic)

(...) I believe Linc Smith posted a long article about using some elements from disposable syringes to make an "air flow limiter". It is probably a very early post on LUGNET. He basically converted one of the T-connectors (which many people have a (...) (24 years ago, 15-Aug-00, to lugnet.technic)

The biggest problem I could see, especially while I had my JCB Backhoe set, was that with the handpump, directional motion in one direction was dependent on the load being levered up - the directional motion on the other direction depended on how (...) (24 years ago, 15-Aug-00, to lugnet.technic)

(...) I see your point, although I have to plead ignorance as to what a reduction valve is. I assume it has something to do with pressure regulation... Would it be helpful if the tank had a plunger of some type in it, which can change the volume of (...) (24 years ago, 15-Aug-00, to lugnet.technic)

(...) That would definately be an improvement, that way you could at least keep pressure all the way, and btw, it is quite easy to control the valves with a axlejoine and say a 4L axle, but sometimes it really looks stupid:). The idea about using (...) (24 years ago, 16-Aug-00, to lugnet.technic)
