I immediately understood why this would be such a huge project. Recreating kit parts in a different scale from scratch is no joke. -- Russ

Some more pictures of the build.

The combination transmission/differential that was used on the chain drive Mack's is shown here in the next two views. It was built up from Redwood blocks, Styrene, nails and bolts. I intentionally left the finish a little rough to simulate cast casings.







Here is a couple of shots of the tran/diff sitting on the 1:24 model.

I have found that I have had to partially assemble the kit model in order to get the
right measurements and proportions to build from.

Another progress report.

Here we have the frame partially assembled and the trans/diff mounted in place with the shift linkage installed (the brass rod in the center of the frame). Also some of the brake linkage is installed along the outside of the frame members (brass rods). The spring hanger shackle bolts are HO scale track nails cut to length, seem to work pretty well.



Another view of the same boring thing. I know the shift linkage rod looks like it is on a angle, that's because it is, I don't know why it was done that way.

The wheels are from the 1:24 kit, I found the tires, that look like pneumatic tires in the model airplane section of the LHS . This combination brought them within 1 inch of scale so I thought that was close enough.

Just as an aside the early Mack's came with solid hard rubber tires, but all the pictures and references I could find indicate that these were changed out to air filled pneumatic tires at the earliest possible time. Since my 1926 Mack is being modeled in a 1939 time slot I took the liberty of doing it that way.



Just a little detail shot of the rear end area, believe me it took a while to build those springs.


More later, thanks for taking a look.

Nice job. That frame has a lot of little parts and must have taken some time. -- Russ

Enjoying this and learning some tricks.
Thank you!

Rick, Thanks for posting. It's impressive to look at.

Thanks for the input guys, here is some more progress shots.


The engine and drive line are completed and mounted in the frame and the front frame cross member completed.

Sorry about the poor picture.



The engine was built up from Redwood blocks, Styrene, wire and brass pieces. The engine mounting in these old Mack's is kind of interesting. The engine hangs from large steel pins centered front and back and just kind of swings there, the drive line being the only thing that keeps it kind of centered. You can see the front pin (brass rod just behind the black water hose) and the hanger assembly mounted into the frame. Of course 69 horse power at 1400 rpm probably doesn't produce a lot of movement in an engine of this mass and weight

The water pump/magneto assembly along with the starting crank handle I used from the original kit. Although a scale difference, it is hardly noticeable once installed. The motor and trans/differential have been painted and lightly weathered waiting final assembly for touch up paint and final weathering.



Same stuff, different view although here you can see the steering arm linkage that hooks to the front hub and tie rod assembly.


That's it for now, thanks for taking a look

Time for a few more photos of the progress as it was made.

The running boards and fenders are roughed in and the floor boards built. The seat box is an empty space that will be filled with lead to give the model some "heft" and help counter balance the weight of the boom assembly.




The fenders are done and the seat built and painted. The brass mounting bracket is sandwiched between layers of the running boards to give them strength and is attached to the frame. Screws will go up through it to attach the cab assembly at a later time.



The firewall/radiator assembly is completed and being test fit. The assembly is hollow and is filled with small pieces of lead sheet to help weight the front of the model because of the boom assembly that will be sticking out the rear.
Also I cut the radiator grills off the 1:24 model and mounted them on this model, maybe just a smidgin small but not bad and sure easier than trying to build something.




The dashboard side of the assembly showing the gauge mounting holes, only 2 instruments in the dash. The arched cutout in the bottom center of the dash is to allow the hand brake lever (coming up from the floor boards) to go far enough forward to fully engage. Remember back in the day brakes were all mechanical so you needed a long stick to get the  leverage required to make the system work.



More to come, thanks for taking a look.

The more you build, the more impressive it looks. -- Russ

Nice - I like it

Excellent!
The engine looks real! (Good).
How did you shape the fenders?

Not sure I really remember it was a few years and many builds ago. But I imagine it was with difficulty.

If I may plagerize Russ for a moment, all is looking quite satisfactory!

Stuart, I hope you realize there's a substantial plagiarization fee for using my copyrighted material. An invoice shall be forthcoming. -- ssuR

Time for an update.

Getting a start on the cab assembly, seems lots of these old trucks no matter the name brand used the basic "C" cab design. Must have been the fad of its time like tail fins or suicide doors. Speaking of doors the doors on this cab pull up from the bottom to the height of the firewall. I don't know why they bothered because except for the windshield and rear cab window the whole rest of the cab was open to the weather.



Using the Monogram model as a blueprint suddenly bit me in the butt. I realized that the frame was way too short to mount the loader assembly on. Obvious solution, lengthen the frame.




After many months of working on this project I became pretty lax in documenting the progress so from now to the finish the picture progress gets a little skimpy.

Thanks for following along.
