zux Posted January 16, 2015 Posted January 16, 2015 (edited) Plastic in different colors have different specs, that is one could shrink more than another, heat required to melt is different too. This is what I became aware of recently. It just cannot be "one fits all". Edited January 16, 2015 by zux Quote
1974 Posted January 16, 2015 Posted January 16, 2015 They use the same mold for all their colors. Except some of the common pieces they have more than one mold ( i.e. 2x1 brick or 3x5 liftarm) to make two or more colors at once. The machines can feed any color for production. That's right Quote
weavil Posted January 17, 2015 Posted January 17, 2015 Plastic in different colors have different specs, that is one could shrink more than another, heat required to melt is different too. This is what I became aware of recently. It just cannot be "one fits all". That's why manually feed the new color with the mold open, then adjust the melting temp and how long the mold stays closed before releasing the part. Quote
DrJB Posted January 31, 2015 Posted January 31, 2015 (edited) Now that we've all had a 'glimpse' of the pneumatics' future (i.e., new parts in the upcoming Mercedes Truck), have you thought about how to put those to good use? I'm thinking/hoping/wishing for a remake of the 8455, but in a larger version. Of course that means TLG will need to bring in larger tires as well. The other vehicle that now seems more 'feasible' is a moto-grader. Those tend to use different-sized hydraulic cylinders, and of all the constructions machines I've seen (and operated), has one of the most 'complex' hydraulics/pneumatics. So, here's what I'd love to see. 1. Remake of 8455, larger, as a flagship 2. Grader, with as many functions as the real thing Anything else? Edited February 1, 2015 by DrJB Quote
Epic Technic Posted January 31, 2015 Posted January 31, 2015 I will probably make an LPE for a car or truck. Quote
jorgeopesi Posted January 31, 2015 Posted January 31, 2015 Well... mining excavator (komatsu pc5500), mining shovel (komatsu pc8000 or caterpillar 6120), grader (any yellow), mining dumptruck (any yellow) , mining wheel loader (komatsu wa1200, caterpillar 994 or 993), there are so precious machinery and so little time .

davidmull Posted January 31, 2015 Posted January 31, 2015 fully foldable knuckleboom cranes Sounds great :) something like 8258 crane? Quote
davidmull Posted January 31, 2015 Posted January 31, 2015 yes Sir Very nice. Would that work on the Merc? Quote
Richard Dower Posted January 31, 2015 Posted January 31, 2015 Can someone please give us an overview of the new parts?...i dont know anything about pneumatics, which parts are new exactly? Quote
efferman Posted January 31, 2015 Posted January 31, 2015 (edited) no, this crane is for the 25 stud width scale for the arocs something between the crane above and this 15 wide crane Edited January 31, 2015 by efferman Quote
aminnich Posted January 31, 2015 Posted January 31, 2015 Ummm, sorry but I think I am going to sell all the pneumatics....that is once I take the acros apart for the pieces.... haha So I you interested in pneumatics, watch for them in the buy, sell forum Quote

paul_delahaye Posted January 31, 2015 Posted January 31, 2015 (edited) I wonder if LEGO customer services will sell the new pneumatic cylinders, or whether they will claim these are part of a licenced set, and as such are not available , like the old Orange panels of the MB Unimog?

dhc6twinotter Posted January 31, 2015 Posted January 31, 2015 I've been working on a pneumatic road grader, and these new cylinders will come in handy in a few places. My forwarder project that I've put on hold could use the longer cylinders, but I'm leaning more towards just using LAs instead. Quote
Richard Dower Posted January 31, 2015 Posted January 31, 2015 (edited) Spotted a pneumatic part from 2014 in a new colour, the T bar is now in Black: http://www.bricklink...colorID=11&in=A Edited January 31, 2015 by Richard Dower Quote
Milan Posted January 31, 2015 Posted January 31, 2015 1. Convert my TC6 entry to fully rc pneumatic version. 2. Convert (build again-improve) my large scale JCB 3cx backhoe loader. Cant wait! 3. Build large scale, but smaller model of JCB JS Excavator. Quote
Saberwing40k Posted January 31, 2015 Posted January 31, 2015 the new narrow 11 stud cylinder would be great to use with outriggers, and really just about everything. I'd probably modify 42043 actually, make the crane arm a proper Palfinger type, in order to use it as a taxi crane for another one of my projects... Quote
jantjeuh Posted January 31, 2015 Posted January 31, 2015 99021 will soon also be available in black. Quote
Brickthus Posted January 31, 2015 Posted January 31, 2015 I would consider replacing LAs with the new 2/11 cylinders. I could increase the arm extension of my Pick and Place Robot with a 2/11 cylinder. 8421/42009 could do with two 2/11s end to end for jib raising and also several end to end for jib extension. The new 1/11 cylinders are more difficult to place since they might prefer slider applications where the sideways forces are managed separately. Certainly outriggers - 4 on 8421/42009 or mobile crane MKIII in a few years' time. the 1/11 cylinder would be placed easily enough in City buildings; they could make something stick out by a significant amount or retract as required. It would be great to see pneumatics used in ranges beyond Technic. The longer extension of these cylinders might help with train decoupling, though on-train compression and control would be difficult (L-motor for compression + servo motor for valve control = expensive!). Perhaps a scenery-mounted system with the cylinder(s) hidden under the track would work better. Real movements on a railway tamper would be great, and would justify the expense of the motors to control the pneumatics. There are great possibilities for Continuously Variable Pneumatics with the longer travel of both these new cylinders. It will be a challenge to improve accuracy and minimise play in the system, with more gearing down needed between the cylinder movement and the valve movements; for variable control hey operate on the edges of their nozzle opening. Whilst I might wish for an updated multi-pneumatic kit like 8455 Backhoe (of which I bought 10) as a parts pack as well as a great model, I'm not confident enough to get my hopes up. Rest assured TLG, if you do make another kit with many pneumatic parts like 8455 but including the new cylinders then I will be buying quite a few! Mark Quote
PKW Posted January 31, 2015 Posted January 31, 2015 Wow, with two 2/11 pistons finally i Could make a decent pneumatic-flipping arm for a new battlebot!! Quote
Alasdair Ryan Posted January 31, 2015 Posted January 31, 2015 (edited) An excavator would be nice if I can find the time. All we need is a pneumatic version of a spool valve. Edited January 31, 2015 by Alasdair Ryan Quote
arik Posted January 31, 2015 Posted January 31, 2015 I'll make a tail lift :-) (Old 2/7 for lifting, new 2/11 for platform tilt.) Quote
zux Posted January 31, 2015 Posted January 31, 2015 99021 will soon also be available in black. Which set is going to include it? Quote
