(...) I agree, but unfortunately my computer does not! My CAD version of the Sydney Harbour Bridge now exceeds the ability of my somewhat antiquated computer to render it (even in MLCad). So until I upgrade, it remains about 3/4 complete in a bunch (...) (20 years ago, 5-Apr-04, to lugnet.technic, lugnet.trains)

(...) I second that! TJ, CAD'ing your creations is very important. Especially, before you recycle for the parts. If you have not used it or would like to find out more information, let me know. I can also demo a bit for you at the April Dinner. (...) (20 years ago, 5-Apr-04, to lugnet.technic, lugnet.trains)

(...) I agree with Steve. HOG it! Besides, your MOC will have so many mechnical parts, eliminating the A-frame cylinders will make it more simple and your life easier, IMO. -TJ (20 years ago, 5-Apr-04, to lugnet.technic)

(...) Well on my crane I went straight for the HOG approach, I didn't actually find out how the A frame was raised on the prototype until after completion. I did consider retrofitting a solution but the prototype utilised a big fat multi telescopic (...) (20 years ago, 5-Apr-04, to lugnet.technic, FTX)

(...) OK, I wanna ask some advice on this one from the big crane builders (yeah that's you!!) I was aiming to be able to lift the a-frame mechanically, but so far have found no solution. I would have liked to use pneumatics, but with the a-frame (...) (20 years ago, 5-Apr-04, to lugnet.technic, FTX)

(...) You should also try with another cylinder to blow air into the pump while it is fully retracted (or being retracted). Otherwise your testing will not reveal a defective non-return valve. The air inflow in the pump through the nozzle should be (...) (20 years ago, 4-Apr-04, to lugnet.technic)

With the buying frenzy surrounding 8438 subsiding as this second reissue being sold out as well, it is time to ponder: What can you do with a 8460/31/38 set? Anyone who has built something out of the 8460 please reply below. When I first thought of (...) (20 years ago, 4-Apr-04, to lugnet.technic)

(...) Yes, I have, see above. It was not easy to get the black cap off, but it can be done without damage to the parts. Only damage was to one of my fingers, but it fixed itself within a few days ;-) Martin (20 years ago, 4-Apr-04, to lugnet.technic)

(...) Thanks for the info guys. I have had one or two older pump cylinders that have lost pressure. Also, some older yellow cylinders (with square bases) are difficult to retract from the fully extended position, due to leakage in that position. (...) (20 years ago, 4-Apr-04, to lugnet.technic)
