RM Mack w snowblower....


Recommended Posts

Thanks , the state brought the truck back from summer storage and getting it prepped for duty again . I took a few more detail photos I was lacking for the hitch frame . The shear size of that unit doesn't show in pics,  but the top of the auger box is 5 ft !!!  20201207_153451.thumb.jpg.3fd92a02e08a13f05b0734e73b2ff61b.jpg

Thanks Gator glad to see ya around hope you've been doing well ! 

Decided to start laying out the framework that mounts this to the truck chassis.  Luck was on my side during last photo op, and showed a large spacer pack shifting frame over around impeller drum .20201210_215411.thumb.jpg.a7b18cb2f7d670a351829d783daeafde.jpg

Then it happened...mocking up the tubing that runs under truck showed an issue . The Mack frames bow out in front...where Oshkosh is straight framed . This will cause the frame to be much wider than planned , but only way .

I'll shim the belly frame out so everything lines up properly when attached to blower . Theres a vertical strut mounted to bumper welded to hitch frame rail that'll tie it together..

Glad you were able to catch the frame difference before you were further along. You’re doing some awesome scratch building here. 

Thanks ! I've wanted to build this piece of snow removal equipment for a few yrs . Its challenging but also teaching me valuable skills 

I decided the simplest way to approach the frame was to follow Mack's design  and make mine bow also ! They already engineered it , why not borrow the idea. 

So using solid .100 x .250 rectangular stock, I slowly bent  a bow into it approx behind the bumper. Then bend again to line up w mounts, and repeat!! I'm more than pleased w shape.  One area concerned me where I attached the vertical mount to the horizontal rail. The glue joint was strong but decided to fishplate the joint .

Here's the progress 20201212_162125.thumb.jpg.d9e1baa0dcb45ddd6179283646c3d256.jpg20201212_203253.thumb.jpg.e818d940218271be6d75ea655a2bda4b.jpg

Fishplates 20201212_205944.thumb.jpg.e3ea9df5be9c916572f9f0dc0233ed3f.jpg

The final frame before adding cross braces ..one side is much shorter , they shift the rail over to avoid the impeller drum. 20201212_210804.thumb.jpg.93c1739b1cf23b13f51cfa7f07c5a485.jpg

now for the bracing and hydr cylinder goodies

More work was done on the hitch frame , started the mounts for the hydraulic cylinder, built up a cylinder to lift the snowblower,  and mocked the hitch frame up before installing cross braces 

This little cylinder took 2 hrs of work ...can't believe how many parts it took 20201213_160835.thumb.jpg.abaabe911dce6817c42e340b2fd4b0aa.jpg

And under the truck

Now a spider web of wiz bangs doodle bugs and thing a ma jigs . Ive gotta plan a few steps ahead or get myself painted into corner 

Thanks for following

So far the squirrels have assembled quite a few parts ..but still a ways to finish up. Last night I started the impeller drive motor , after mocking up the mounting plate .

Here's all the parts the furry buggers stashed around the bench..The discharge chutes still need clean up 

20201216_210449.thumb.jpg.4111706fe9191aee7043e500328742c5.jpg

The blower lift assembly parts made from several different bits then sanded into shape

Lastly the motor mounting plate ready to accept the drive motor once its fabricated.

Heres the real one for an idea of whats ahead...

Jeff your doing an awesome job with your scratch building you don’t need any squirrels or Santa Elf’s. 

Lol thanks ! Didn't really want the squirrels help anyway I keep stepping on the shells 

Santa has his hands full w our daughters request anyway..she would like a dinosaur..and not that talking purple one

Better hurry up, looks like that could be put to use TODAY!   Nice scratch building and the details look great.

Haha  ! I'm actually surprised they didn't send it out to help . Road crews south of me were getting their plows buried after snowfall levels topped 40 inches ..unheard of in this area .

Great work, Jeff.  With all those doodads, squirrels and thing-a-ma-jigs going in there are there any widgets???

plenty of widgets..half the fun of building from photos is trying to figure out how parts get fabricated !!  Theres a bunch of fun parts coming soon..just tackling the chutes now.

Outstanding work Jeff. Love the auger....................same exact construction method I used on my paver................shapes and pieces. Absolutely beautiful, and very timely with the snow upon us!

funny how those kept me awake, then it clicked ..I think the major assemblies are close, now to add life t each making a small model from all of them. looking at certain parts now look boringly simplied, but once the bolts, widgets, and thing a ma jigs go on..it should pop

Big mock up day ! Assembled the chute tower mount and had to see how it looked together 20201227_103332.thumb.jpg.ac1e8b10a3c9037df3ef034f026bc4ff.jpg

20201227_103412.thumb.jpg.87222ea793b7ab7f6e0aa5d99fe29aa0.jpg

I almost had a panic attack when it dawned on me the impeller drum wasn't gonna fit..but it dropped right in..whew !!!20201227_104047.thumb.jpg.528d4b9f20527adf455775066db57dbf.jpg

20201227_103530.thumb.jpg.add25a916182827dc1f2a8c6acab7f37.jpg

Tossed a few braces and Meng bolts on for detailing.  After looking at bare plastic for weeks this felt really good! 20201227_172126.thumb.jpg.9937a77118d1a2bd4527086f98d6515e.jpg

20201227_172132.thumb.jpg.7c78aa55315755fb15e849653d7c148f.jpg

One major part i wanted to knock out was the drive motor / cylinder that rotates the drum . A few pieces of rod, and square tube made up the assembly.  The gear was found lurking in a spares bin

Back to work tomo to pay for my snow tires...
