5150 Lego Posted March 8, 2006 Posted March 8, 2006 Was wondering if anyone had a tank or 2 they'd like to sell. I'm up for trades as well. Just let me know what you would like in tade, andi'll see what i have. I have alot of techinc parts, as well as regular system. Thanks for looking! Brandon
gylman Posted April 4, 2006 Posted April 4, 2006 A vast number of these have now appearred on bricklink (since they seem to have become so valuable). One person even selling 38 of them@!!!!! Where did all these come from all of a sudden. http://www.bricklink.com/search.asp?q=67c01 Let the feeding frenzy begin!
5150 Lego Posted April 5, 2006 Author Posted April 5, 2006 Yup. 2 days ago i was lucky enough to pick up 2 brand new for $12.50 each. while i was at it purchased the new tellahandler. One question though.... How do so many people aquire so many of these? And in new condition???

I've noticed that, too... Yup. 2 days ago i was lucky enough to pick up 2 brand new for $12.50 each. while i was at it purchased the new tellahandler. I got the telehandler about two weeks ago. Nice set, again I was impressed by how they managed certain functions. Especially the steering was new to me. And it's a set were the alternative model also looks good... IMHO...
Mithrandir Posted April 5, 2006 Posted April 5, 2006 Yup. 2 days ago i was lucky enough to pick up 2 brand new for $12.50 each. while i was at it purchased the new tellahandler. One question though.... How do so many people aquire so many of these? And in new condition??? You used to be able to order them from www.legoeducationstore.com; $10 for 2 airtanks. I'm guessing some smart people ordered a bunch and sat on them until they became valuable. I ordered one pack back at the end of December, and they didn't ship it to me; said it was backordered. I later found out the part was discontinued and gave up all hope of getting them, but just yesterday I got a shipment e-mail, so I guess they finally found some to ship to me. woohoo.

I ordered that yesterday. I finally gave up waiting for TRU to get it in stock; and besides they'd probably charge $35 for it anyways. Looks like a good set, but honestly I'm getting a little frustrated at the abundance of red sets. LEGO: PLEASE MAKE A BIG GREEN TECHNIC SET (the lime-green dune buggy doesn't count, I want real green)
Sir Dillon Posted April 6, 2006 Posted April 6, 2006 I know this may be a dumb question, but why exactly are these pieces so saught after and expensive?
gylman Posted April 6, 2006 Posted April 6, 2006 I know this may be a dumb question, but why exactly are these pieces so saught after and expensive? Using an air tank allows you to "store pressure", allowing you to pump up the device, and then run it for 10-20 seconds without further pumping. They also release their pressure more evenly then if you are directly powering the device with a pump, so movement is smoother, not jerky. The effect is magnified if you chain then in series or parallel (I think parallel works better).

I wish they would have had some good peices like that at my local lego store. They usually only have basic bricks. Once in a blue mood they'll have some technic bricks, but i have more than enough of those now. I guess i can't complain too much though. I was able to complete my trailer project that i made to go with truck 8436 by going through the lego stores pick-a-brick.
Mithrandir Posted April 6, 2006 Posted April 6, 2006 I know this may be a dumb question, but why exactly are these pieces so saught after and expensive? Basically, they're "air batteries"; they're the only things that will store large amounts of air (and therefore energy) so that you can have large-scale pneumatic projects work, without having to re-pump your cylinders after you throw every switch. Personally, I think Lego severely underutilized them in their sets. Most pneumatic sets would be augmented with them, but they don't have them at all!

Personally, I think Lego severely underutilized them in their sets. Most pneumatic sets would be augmented with them, but they don't have them at all! A couple weeks ago, i bought both 8439 techinc front end loader, and 8455 techinc back hoe. The loader came with an air tank, and the back hoe didn't. Let me tell you. Now that i have a set with an air tank, its hard to imagine ANY pneumatic set without one. Espeacially ones with 3 or more cylinders. That is my biggest beef with 8455. With 10 pneumatic cylinders, to takes quite a while to get them moving. Even with 2 pumps. Luckly i was able to grap a couple of tanks for a good price on bricklink and have installed one on 8455. Wow. What a differnce. I'd like to install a second, but i can't find the room for it without drasticly changing the look of the model, or putting it somewhere out of place. Annother set i cam see this being really usefull (and i know glyman will vouch for this ;) )is the airtech claw rig (sorry, can't remeber the set number). With its on board compressor, and an air tank or two, this set woulod deliver endless funtion and play time!

With its on board compressor, and an air tank or two, this set woulod deliver endless funtion and play time! Absolutely!!! I have done this. It didn't look so great, but it worked well. With the Claw Rig (8868 - I have this number tatooed on my chest - the best technic set of all time IMHO) there is no problem with delivery of pressure constantly - the compressor mechanism does that for you. This is only pneumatic set with this mechanism as a designed part of the set. However, the opening/closing, elevation/lowering, and rotation of the "claw" are jerky without the tank, presumably because the air pressure the compressor provides is not even (more pressure on the instroke, less presure on the outstroke). all the movements are FAR smoother with the tank. I have an uncontrollable urge to hoard air tanks. MUST...... CONTROL..... SPENDING.......

I have an uncontrollable urge to hoard air tanks. MUST...... CONTROL..... SPENDING....... You could also solve this by using a 2-or-4 (or even 8 X-D) cylinder pump. For a 2-cylinder pump: Use a 3- or 4-axle (depending on how wide you want your pump mechanism), put two pump tops on the axle, and close it off using either 2 2-stud liftarms (3-wide version) or 4 2-stud liftarms (4-wide version), attach axles to the open holes on the liftarms, and make sure that one pump is facing one way while the other is about 180 degrees away; so that when one is on the upstroke, the other is on the downstroke. Alternatively, you can make it even smoother by using 4: use an axle connector (the three-long one, two axle holes on the ends, one pin hole in the center); put one 4-axle in each axle-hole, put in 4 pumps (2 on each axle), and close it off like the 2-cylinder pump, using 2-stud liftarms (I actually made one using a 36-t gear instead of the liftarms; more compact for what I was doing). So you'll end up with solething that looks like: .............| -------------+--------------- ............++ ....pump1...| ............|.....pump2 ............+-+ ....pump3.....| ..............|...pump4 .............++ -------------+--------------- .............| Using this configuration, you'll end up with a pump where each cylinder is ALMOST 90 degrees in phase with the next one (it's not exact if your pumps are at an angle to the bracing beam, but close enough so that you can't tell when it's running). I have an 8-cylinder version of this, where there's a second row of pumps directly on top of these, 45 degrees out of phase so that none of the cylinders hit each other. It's really cool to see it in action. I have that hooked up to 4 airtanks tanks in parallel. Anyways, there's an additional benefit to using airtanks that almost no one recognizes: Since you're dealing with more air volume, it takes a lot less torque to increase the pressure, meaning that you don't need a super-powerful motor in order to get up to high air pressures. I hooked up my 8-cylinder, 4-tank pump up to the clear "Motor Movers" motor, geared down using a screw gear to get a ton of torque; after a minute it always causes a tube to pop off somewhere in the network, heh.
