Thank you to all who have taken the time to answer my pneumatic questions.
Lugnet is a great place to find answers!
The pneumatics for this road grader are not hooked up yet since there are 2
major questions left unanswered. The first one is regarding the location of the
pump. Where is the best place to put it so it looks good? I left a verticle
"hole" behind the engine for it but don't know whether it would look silly or
not. The other question is how to route the hoses for the front tires so they
don't scrape the tires. This means that scraping must be avoided at every
possible combination of steering and tilting. The small pistons fit nicely
there but I still need a design to allow the hoses to tilt out of the way when
the tires move closer. The ports themselves are close to the side of the tires.

There was a problem with the blade assembly swinging from side to side, but I
decided mount a dowel behind it that is braced on either side. This allows for
up/down movement as well as turning. Both pistons move indepenedntly to tilt
the blade but can work together to lift it up and down.
BTW- Happy Thanksgiving to anyone who is celebrating it. It is a cold one here
in Ohio!

Otherwise I'd try to pull the hoses back towards the center between the two ports of the piston, (...) (19 years ago, 24-Nov-05, to lugnet.technic)

| (...) My personal preference is horizontal mounting like the 8436. That might look good mounted above the blade running front to back? (...) It appears that the two front cylinders work as an opposed pair ? if this is correct, you may only need to (...) (19 years ago, 24-Nov-05, to lugnet.technic)
