Great Work, Jeff!

You are showing a Master Class in scratch building.

Worked on the blade carrier today, luckily found a few photos of these assemblies on the dark web. This plate houses the cylinders that push/ pull the entire packer assembly and also the cylinders that curl / fold the blade to drag the trash into the container box. Heres an image i found for ref.  

Using my blade for size comparison,  I drew a pattern on paper suggested by Mopar-D . After it fit , I transferred to plastic . I used 30 thou for the pan, then 40 for framework. The rest of the bracing was similar sizes judged by the photo. 

Sistered up with the blade 

straight on view showing where the  enormous rams will attach 

I'd really like to make my cylinders functional, only to have movement to display all the components..pretty sure this was posted awhile ago how this is done. 

Thanks for following along

Amazing work going on here! Excellent craftsmanship!

Wrapped up the blade scraper/ carrier assembly. I wanted the cylinders functional,  and after a chat w Tom Decker, came up w a solution. Its basically a set of telescopic tubes, then I added a machine screw to keep tube from sliding out. The end is a tapered cap, hiding the screw  ! 

After building 4 of these,  drilling out the attachment points,  then fitting together I mocked everything up.

I hid a bit of angle underneath keeping the parts from shifting around. 

A view from the hopper

I started the top cover and light bar next. Once the interior is painted this will get permanently attached

This is way cool.  Brings back memories.   I was a trash man many years ago.   Now for some 1/25 scale trash stench?   Looking sharp so far.

[Mopar - D]

Wow Jeff this is very impressive! I’m glad to see that the paper cut outs worked out for you. I know they helped me.

Thanks , and glad it brought back memories! A couple worker was a trash man also, been fun showing the progress photos. He's helped answer several questions along the way.

I plan to add some trash to the hopper w paint wear..dunno about the scale smell though lol.

Great scratchbuilding!

Little wknd sneak peak .. 

Huge mock up after getting the tailgate to function. The tires are just place holders till the real ones arrive from Moluminum. I realized I was missing a bunch of chassis parts from this parts box. A quick search on eBay net me an entire chassis bundle ..yeah more parts lol.

I'm planning to shoot some primer on the packer after I fab the hydro tank

 

[Rockford]

That's just amazing work, really impressive stuff. 

[gotnitro?]

The hydraulic tank and pusher cylinder is wrapped up, as is the front controls to empty the packer. The cylinder is telescopic tube mounted w tabs . I decided to make everything functional to pose the pusher after paint .

The tank is detailed w meng bolts,  and the drain valve is an etch emblem from a 69 Camaro...forgive me its the closest I had. Theres even a site glass to check the oil level lol

The pusher cylinder empties the garbage once full..

Last thing before I could start primer was the front controls. A couple sewing pins mounted to some square tube seemed to look close 

There will be a conduit of pipes running from the tank and controls, so after paint I'll add them. .032 solder wire is tasked w seed beads for hydraulic fittings

 

[Mopar - D]

Awesome progress Jeff! Looking forward to seeing it with primer on it.

Thanks ! It won't be nearly as gorgeous as your Challenger, but a proper work truck.

I just received the delivery tracking for all my inbound parts, so I should have a large amount to paint .

Looks amazing!

I had a little excitement last night when I tried to paint the tins. Seems the rattle can valve was clogged inside the can. I tried cleaning the nozzle but nothing would come out. I decided to decant the can into a jar..now my yard looks like a murder scene PSA only whack a rattle can on cardboard unless ya want your green grass different colors lol

I'll thin the paint and use the Iwata for now

Hydraulic cylinder hints: 1. Use thread inside to stop ram pulling out of tube. Connecting end of ram to top of cylinder. 2 Use 3 different size tubes: larger diameter as outside, inside diameter tube would be shims on ram and cylinder. shim at top of ram and shim at bottom of cylinder prevents ram pulling out. this can be accomplished using mix materials such as styrene, brass or aluminum tubing.

I did a short tutorial on making hydraulic cylinders a while back.  They may be still in the how to's.

[gotnitro?]

Thanks for hydraulic ram ideas..but I've had those done a few weeks now lol

I sprayed the frame tonite w airbrush..man it takes forever but much less mess. Thinned rusto regal red 50/50 w tamiya lacquer. Laid down smooth w great coverage.  Kinda shiny for a garbage truck..but I can address that 

[Mopar - D]

Looking good Jeff. 

[gatorincebu]

 

      Jeff,

             Very nice scratch building and fabrication , I'm impressed.  I like your choice of truck in the Mack .

This rig should look really good .When you finish it .

 

   Be Well

The tins are done , sprayed w rusto jd green.  The parts dried overnight so today I set everything together for a mock up. 

The packer body will be a very light gray, I planned on spraying this wknd,but our daughter came down w a cold after a week in school. Dr said usual ear infection and sore throat going around. 

Thanks for everyone's feedback

[Ace-Garageguy]

Impressive fab work, paint looks great, lots to love on this one.  

[Perspect Scale Modelworks]

Beyond amazing.

[gotnitro?]

Thanks everyone for the feedback it really means alot 

Today I installed the detail master etch grill and lettering. I've gotta say it really makes the hood pop.

While I was puttering,  the packer body was painted krylon glacier gray, a matt light gray. I should've tested this first, those cans really blast paint and it caused a few sags. 

Overall I'm really happy how the colors work together. Now to finish the Maxi-dyne engine, and get the chassis wrapped up

Jeff
