Jim B Posted August 10, 2022 Share Posted August 10, 2022 I am finishing up the AMT 1972(ish) Autocar A64B. The kit comes with some black vinyl tubing for the tractor-trailer air lines. I want it to look moderately correct, so about how long were these hoses generally? Or were they vehicle specific? Thanks. Quote Link to comment Share on other sites More sharing options...

Jim B Posted August 10, 2022 Author Share Posted August 10, 2022 That long? Wow, didn't think they were that long, but I guess longer is better. Quote Link to comment Share on other sites More sharing options...

W Humble Posted August 13, 2022 Share Posted August 13, 2022 Minimum length of the 'glad-hand' airlines was enough not to pull-up tight on a maximum angle turn -- or when backing 'jack-knife' style. Too short and they broke. Thus, they always drooped down in the old days, then when the 'coily' style evolved just dangled and bounced. Lots of trucks, especially conventionals with long wheel-bases (twin screws) had jack-staffs to support them and provide a mounting place when not pulling a trailer. I used to see small memo-type pads with coily-type retaining cords for the ball-point pens they carried; seemed like a good simulation of the latter day type. We always spat on the seals of the air-line glad-hands and rubbed them on our palm to make sure (?) of air-tighness. Well, you had to depend on those trailer brakes on long grades, man! I remember the time in '73 when I was comin down Stirling City grade with a load of stumps, there by Magalia road... Wick 1 Quote Link to comment Share on other sites More sharing options...

Always carried spares. Quote Link to comment Share on other sites More sharing options...
W Humble Posted August 13, 2022 Share Posted August 13, 2022 Right! I always try to look where I'm spitting! I just wish my boss would have sprung for some spares! Then, there was the time... Wick Quote Link to comment Share on other sites More sharing options...
Dpate Posted August 14, 2022 Share Posted August 14, 2022 These are nice too for air lines for the back. Quote Link to comment Share on other sites More sharing options...
