    this was my first time out for a drive in it in about 6 years. it was good to get out for a 30min cruise with another truck nut.

    Great to see her stretching her legs! Must have felt really good after 6 years. I'm building yet another RS700 model at the moment. Stuck at home in Covid 19 lockdown!

    Many thanks.

    My choice would be the RS if I ever do but the Pete definitely has attractive and not very common appearance.

    Old School Pete. In my humble layman opinion the 359/289 was the last really good looking Pete. It still had plenty of subtle curves. (Had to have round lights, though). The next generation had all the radii sharpened so they got a kind of squared off look to them.

    Kenworth did the same with the W900B. I much prefer the looks of the W900A.

    Not almost what you meant. That collar and pin setup was used on DM's including DM800 you are building. The style with rubber pads I mentioned was what was used on L-models including LT's. I have that setup in my 1945 military Mack. The front axle assembly used there was off a L-model I belive. The picture of the light green frame (not khaky) is a C-model front spring rear bracket. As you can see its body is similar to a R-model part by the shape but accomodates the spring end in rubber pads clamped with a cover. Difficult to see on the below the chassis picture but you can if zoom in.

    I can see what you mean. The spring is clamped between the two ends of the rubber which is different to the collar arrangement which I thought you meant. Maybe this style predates the collar set up. More research needed!

    Of what i also noted a C-model had front spring rear brackets with rubber pads for the leaf ends to attach. This F-model brochure represents something looking similar as much as I can determine from the drawing. My R's have rear ends of springs hanged on shakles and I belive the most R's had them of that style. Not sure of early series trucks though.

    I hadn't noticed the difference before. I had a look through a few pictures and see what you mean.  All the B's I looked at and a G have the ends of the springs trapped in a kind of collar against what looks like a pad or roller. There is also a cross brace spanning across the underside of the hangers closing off the collar. The DM800 model I am making has this arrangement. Some of the early metal dash R's also had the collar arrangement though I'm not sure if the cross brace was used. All the later R's had shackles. All the Western R's I have seen had shackles and the image of the fishbelly frame looks like it has hangars designed to take shackles.  Judging by the age of the trucks I am guessing it was a design change, maybe late 60's or thereabouts because I haven't come across a newer truck with the collar. I suppose it might also have been an option.

    On the topic of B cabs, on pure aesthetics, I like the curvy cab because of the purity of the design: all curves and very 1950's. I can also see that from a practical view the L cab offered a bit more for the driver. I think the L cab looked especially great on the LT but it does look like a design from an earlier era (in my opinion.)

    Wow! That's one almost new fact to me. Have never seen a F-model with that shape of the rails. Any pics?

    Here are a few pics. Sorry about the quality. The one with the cab up is a steel dash F700. It's kind of hard to see but it looks like the skinnier frame. I've included the fish belly for comparison.

    What really surprized me in a C-model it was built on a pair of R-model frame rails. And if we take to account C was introduced earlier it means Mack designed that frame for C and further kept in production up to 2004 year.

     

     

    That frame was first used on the F model which was introduced in 62. At some point the F model got a new frame with a deeper front section but Mack continued using the original frame on the R model. It probably made sense to use it on the C model as well.

  6. I've just managed to answer my own question. I found another picture where I can just make out the bolt patterns on the frame rails and I can see two sets of 6 bolts close together so they must have put the two crossmembers very close together. I think there is a similar thing going on under the back of the cab on some of the Western R's, including the 1st gen Superliner. There's a cab mount crossmember which is a kind of curved bar and immediately behind it there is a standard crossmember with the forward edge of the flange cut away so it butts up directly against the cab mount. I don't know if there was a standard dimension between the rear trunnion and the crossmember to the front of it but that crossmember always seems to be in more or less the same place as far as I can see. There must be some science to it. I'd have thought someone would have calculated where the stresses were going to occur. By the way, The cab looks fantastic, Vlad. I cant't believe how much work has gone into that. It's a work of art!

  7. Building a model of this RS700L. It appears to have an auxilliary transmission visible just back from the diesel tanks and in cab shots clearly show 2 sticks.

    I have an RS700 brochure whith a photo of an aux. case mounted between two standard Mack crossmembers but if I mount the casing in the position in the photo posted it places the rearmost of those crossmembers very close to the next one. I could move the next crossmember further back but it looks to me like the spacing of the camelback trunnion crossmember and the next crossmember forward of it is a standard dimension.

    On a full sized truck, what would be more likely, Keeping the standard dimension between trunnion crossmember and the next one forward and just have two crossmembers very close together or reducing the distance between trunnion crossmember and tne next one forward to create more even spacing?

  8. Finally found this video I had been searching for.

    There was also a thread about the Eddy Liner Mack a few years ago. A cross between a Superliner and a Valueliner with a Cat engine.

    Were factory Australian Super Liners and Value Liners ever offered with non Mack engines like their US counterparts? Back in my travels in Australia in 91/92 I did see a Cat powered Super Liner but not sure if that was original or not.

    electric to chain.  800 looking good.  mid '70's  I had three   DM 800's models  on display at mack dealer in ct.  since being on this site  seeing interest in models  I pulled couple of 800s out of storage. trip from ct to tenn  took it's toll.  DM800 cut/stretched made into wrecker. hopefully will repair and figure how to post pictures.

    I agree with the chain drive for the tarp.  Can't wait to see the finished product!

    Chain drive it will be. Both DM and trailer have progressed quite a bit since I took those pictures. Nearly ready for paint.

    Would like to see pictures of your DM's, mechohaulic.

    Just saw this post. (been busy with kids!!!)  Amazing work once again!  love the detail you put into these trucks. are you still making model parts kits for the RS700. 

     

    I recently knocked the dust off my old RS700L and started to get it ready for the road again. Its been about 6 years the last time I went to a Truck show with it.

    Busy with kids! I know all about that.

    I saw your post about waking up the old dog and have been following your related threads. She's looking really good. I can't tell that the paint needs attention. I'm sure she'll still turn a few heads at shows.

    I haven't run off any model parts for a few years now. ( since my friend with the casting gear moved to Ireland and took it with him!) I've got a few bits and pieces left.

    Working on a DM800 and dump trailer at the moment. Superliner, another RS700 and an F model at various stages of incompletion.

  11. Martin Penwold would have to be in his 80's by now! (At least Kris Kristofferson is 83). Maybe one or both of those kids living up up in Spokane has taken up the mantle!

    It's a great project though and is really looking good. It's still instantly recognisable to us Convoy fans and I don't know that the Duck would have had brand loyalty because when we first met him in song I seem to remember he was driving a Kenworth.

    Personally I'd have imagined him moving on to a first generation Superliner which he'd have driven throughout the 1980's before replacing this with one of the last Superliners which would have seen him through to retirement!

    Looking forward to seeing it all finished and the new website as well. I really miss the old one.

    Link to my 2nd RD model.

  12. Pictures of trailer. The DM started out as an ERTL kit with an AMT R model cab and scratch built long frame.

    Regarding the tarp, it does look like the motor is mounted down on or above then leftside treadplate platform at the front of the trailer and is connected to the tarp roller by either a belt or chain with a guard over it. It would seem more logical to have the motor on the tarp bar but this must be the 1% that didn't so I'll make it this way.

    Still wondering if the drive would have been a chain or belt.
