Lots of inspiration (aka great modelling) here, time to try my hand at a logging rig. I have an AMT W900 and Peerless logging trailer and this photo from Ron Adam's "Kenworth Trucks 1950 - 1979" is too interesting not to try duplicating: W900 with a l-o-n-g load. Couple questions about it: What rear suspension would the tractor likely be equipped with and could this truck have left side stack only or was right side stack damaged prior to photo being taken? Left side stack tip got "pranged" recently judging from photo.

Robert,
If you look over the right side of the cab on the photo, you can see blue smoke which indicates to me that the Stack on that side was thumped before the photo and my be broke off shorter than the left one. But I have seen west Coast loggers with single stack left and right but mainly the singles were on the right side.
I (when I build Logging Trucks) Floating beam type or sprung suspensions on my rigs as I build the older style. Hendrickson or something on that nature will work, although I have seen some of the newer K-whoops with the airbag suspension like on the old AMT Centennial kit, where you have four bags per axle. It really depends on your preference.
Judging from the left stack on this rig it looks like the shop may have bent the top over as it is flat, to divert heat and smoke to the side of the rig. I could be wrong on that.
A load like that here in the states would be illegal on the hiway but legal for off Hiway the way it is loaded. But then again that's the difference in the areas. Another thing I noticed in the photo is there is no Headache rack on the truck either, that I can see. It is equipped it looks like with a Peerless Road runner trailer and bunks. Another thing is that it has a extendable stinger on the truck where the trailer connects. To get a close up of these there is a posting I made on this forum which shows the basic three types of stingers used on these trailers. Mike (tufftin) has made numerous posting of them also. Look in the lunch room of this forum.
This rig will definatly make a conversation piece and great model. Will definatly want to see it when completed.

Thanks for the info William, Hendrickson suspension will be the choice then as that's what kit (AMT W900 "Watkins") has. 5 hole steel disk wheels, just to be different I think I may put a 318 "De-stroyit" engine under the hood, would be plausible with 2 stacks.

You're right Carl - I may need to give figure painting a try (been many years since I did any) as well!

Many log trucks used the Hendrickson "Biscuit" suspension. The rubber bicuits came in different weight combos. They were mounted between the frame and the walking beam suspension. Worked great for logging but one hard ride when bob tail. I googled Hendrickson and came up with this photo. The rubber biscuits could be ordered for weigh combos from 40,000 to 120,000 pounds.

All of Wayne Bares truck had those Bisquits in them and when not carrying a load they could make a rough ride out of a smooth road. Simpsom and the other units I remember had them also. Thanks Mike for jarring the memory a little.

We have an IH S2600 boom truck at my work, it has Hendrickson (spring) rear suspension, even with empty weight of 32,000 + it rides rough! Can only imagine the rubber biscuit suspension on a bobtail logger....... Is the Canadian supplier Plaskit? If so I have bought a number of items from him (Daniel) in the past, always been excellent to deal with and good quality/service. I may add the biscuit (we often call them rubber block here, used quite a bit on dump/mixer trucks) suspension to an order.

If you don't already have his e-mail address, Daniel can be reached directly at plaskit_resin@yahoo.ca
I'm placing an order shortly, he doesn't cast the Chalmers suspension but has a good variety of Hendrickson in different configurations.
