    Pretty slick! Great build quality! Going to follow this one, closely. Very cool.

    Sean, really looking good. Your six pot Detroit looks way cool. This project is off to a great start. Looking forward to updates.

    Clayton and KJ hit the nail on the head. Back in the 1960s, a class 8, on highway truck could only be a maximum of 57' and weigh 72,800 lbs. The easiest way to get the most payload within these regulations, was to put the driver over top of the engine, and keep the wheelbases under 190 inches. The cabover ruled the road, especially when you factor in all the restrictive bridge laws that could, and would be enforced. Each state setting something different.
    Look at the AMT truck and trailers were all modeled off equipment of the day, 40 footers, and short wheelbase cabovers.
    l did the math, and it was 33 years ago, I drove my first truck. It was a red and white, white freightliner FLA. Catpowered and 15 speed equipped.  
    One of the best things about cabovers is the visibility. You are not looking around a hood, or exhaust, or sleepers. You are right overtop of the left steer tire, inline with the side of the trailer. Backing up was never easier. Blindsiding was a bit tougher, though.
    Clayton, you tastes and mine run along the same lines. Freightliner FLA, Pete 352, 362, and Kenworth K100 are my favorites. With honorable mentions going to the CL9000, IH9670, Road Commander II, Astro 95, and  IH 4070B.
    There ain't no feelin' like Cabover mobilin'.

    ^^Preach, Brother, Preach.
    If it weren't for the Federal D.O.T., Creeper Cops, Steering Wheel Holders, and ignorant 4 wheelers, it would be the perfect job. 
    I am all teary eyed and nostalgic now, myself. Lol.

    Yes, Michael, very similar effect, only you use the throttle to break the torque lock in the transmission instead of letting gravity do it for you.
    Hey Clayton, you, obviously know what I am talking about. And know it well. It is a great feeling when you row through the gears, hitting each one just right. Did I mention I HATE class 8 trucks with automatics. It is a well practiced, well executed skill set that is dying at an alarming rate. 
    If you notice in the video, the driver's left leg never moves after he gets rolling. Not even when he splits gears, or changes ranges. You can tell, he LIKES driving that truck, and showing off a bit.

    Hey Michael,
    When I first started driving, Over 20 years ago now, it was explained to me in these very words:
    "The clutch is for starting and stopping, ONLY." Spend any amount of time with the same truck, and you learn its peticular traits. You learn how to shift to neutral just by lifting your foot off the throttle. Then, hopefully, you learn how to shift it into the next gear, up or down, just by engine RPM only. Down shift and you raise the engine speed with the throttle, up shift and you wait for the engine speed falls to the normal gear step. The gear step being the difference in engine speed, at the same road speed, (MPH). For example, if at 50 MPH, in 12th gear, and the tach says 1100, drop to 11th gear and the tach would read 1600 RPM. This varies with every different transmission. An 18 speed may only have a 250 step when you split each gear, 1-2, 3-4, etc. While a 9 speed will drop, say 500 RPM, having only half the available forward gears. A car, with a manual transmission does the same thing, just with a bigger swing of the tach needle. 
    Floating the gears, basically, is shifting, up or down using only your right arm and right foot. No clutch. With practice, the shift lever, almost 'floats' into the desired position. No grinding, nashing, or missed gears. It will literally shift with surprising little effort. The alternative, is 'Jamming' it into gear. Yes, the term Gear Jammer, long before my time, was a derogatory term.
    Clear as mud?

    Angel, if you have an air brush, I have the exact colors, mixed by Scale Finishes. A 2 oz bottle of Kenworth Ivy Bronze, metallic, and 1 oz bottles of Kenworth Lime and White. I was going to build a 1/16th VIT, but it is so far down the list of projects, I would let them go, if you what them. All 3 are premixed, brand new, and unopened. P.M. Me if you are interested. Reasonably priced as well.

    Hey Sam,
    They pretty much are. All have the extended hood, and 3408 Cat in them. About the only real difference is the color they are moulded in.

    KJ, beautiful, beautiful work! You can almost see the grain dust flying off the auger now. Truely inspirational.
  10. purepmd added a post in a topic 1st Annual, Big Rig Build Off, 2017 Calender build contest.   

    Really Great to see this up and running! I have to make sure "Plan A" is possible, before my cat and bag part ways. Do have some good "Plan Bs", though.

    First Plan B...Ford CL9000:
    Second Plan B...International 9670:
    Third Plan B...Kenworth W900L with either a 3406E or Signature 600:

    You say 'liberties', I say enhancements! Far outshines the box art while retaining all of the appeal, Outstanding work.
  12. purepmd added a post in a topic Post your "Snap" kits.   

    JT, imagination and execution perfectly paired. Really liking the KW / Ford combination, very original.

    Landon, your all black Pete istantly made me think of that show truck, Project 350, nice work. The black, white and red Pete stopped me in my tracks, great color choice.
  13. purepmd added a post in a topic all White - Autocar here   

    Hey Mark, thanks for the kind words. They are decals, my hands are not that steady anymore, They were the ones that fit the best off of the Can-Do wrecker decal sheet. One of the ones I have yellowed, badly, completely unsuitable for most colors. I figured, some real close trimming, and over black, they might work.
  14. purepmd added a post in a topic Snap Pete redo, Done!   

    Now thats what I call a make over...Well Done!
  15. purepmd added a post in a topic Any thoughts?   

    Richard, I don't think Anthony is nit picking, at least I hope not. I think he was expanding on another aspect of the trucking industry, as awhole. Air ride is, probably, the single, biggest game-changer to come along. So much so, Freightliner had to buy it's way into that game. I did not get into that because I was aware of how long winded I can get when hisory and trivia start rolling, and that is reall long post already.
    You do make a valid point. Let's just enjoy the hobby we have managed to bring with us to this point. I just hope nobody decides not to participate based on their peticular likes and dislikes.
    I may be wrong, and Clayton, please put me in my place if I am, but when I read "show trucks" and "no weathering", I took that to mean, if it is old, make your build look like a restoration, not like it was rode hard and put up wet, or, if you like low pros, full fenders, and wild paint, go to it.
    Personally, the variety would be welcome. Use your skills to build the best representation of what floats your boat, then show it off to the rest of us. Just my perspective.
