Paul's Technic Tractor Attachment System (PTTAS) - Dozer Blade

This is my latest attachment in the PTTAS series. This is a dozer blade, used for pushing and moving items and clearing land. The knob on the side is used to raise and lower it.

MOC - C Model of 42075 - Claw Loader

I would like to present my latest MOC. This is a claw loader C model of set 42075. This has been built using only the pieces from this set.

It features:
- Hand of God (HOG) steering via the knob on the top of the cabin roof.
- Front arm lifting via the black leaver in front of the cabin. This also has a lock to keep it in place. This is required as due to a lack of LA's and no worm gear included, it would not stay in place as it went up.
- Manual claw opening, this uses the shock absorber to close it.

I had built a winch for the rear but this didn't look "right" so I took it off. You can see in the last photo the parts which were left over after I finished this.

I spent about 7 hours over the past few nights building this.

I had to go back a few times and change parts used as I needed them for another parts of the model. My building process was:
Lifting arm
Body work

Overall I am happy with how it worked out, it ended up better than I was expecting.

Happy Birthday to Me

Birthday present from my wife and children. One will be used to make a C model which I am working on at the moment. The other will either be built as the A model or used as a parts pack for a future MOC.

LEGO Technic 42078 B Model - Mods

Recently I purchased and built LEGO Technic set 42078 B model (Mack LR garbage truck). After finishing the build I had a couple of ideas for mods to improve it.

These are:
- Removing the lever on the front forks. I don't think this is really needed.
- Adding some extra panels to the bin to make it load and unload easier.
- Remove the top LA and other parts used to open and close the rear hatch, this now opens and closes based on the internal compactor.
- Add a rear catch to work with the above.
- Change the gearing to allow the compactor to work easier. This includes a better leaver to turn it.

I also tried making the rear body tip, while I was able to make this work it was not very reliable and would struggle with any load in the rear body so I pulled this up and put it back to standard.

Below are some photos and a video of all of these.

LEGO Technic 42078 B Model - Build Process Review

A quick and dirty review of the build process of LEGO Technic set 42078 B Model (Mack LR Garbage Truck)

Today I purchased this set, with the plan of building the B model (Mack LR Garbage Truck). This is my first LEGO Technic set in almost two years so I was super keen to get hold of it and start the build process.

I spent an hour and a half unpacking and sorting the parts before using the downloaded building instructions to start the build process. I spent two hours building last night and got just under 25% done.

Last night I sat down with the plan of doing a couple more hours of building of this set, if I could get a bit over half the building done I would have been happy. I started at around 7:30pm with a plan to build until around 9:30pm.

As the night went on the build process got easier, less parts to search to find the one I needed and less complex steps. Around 10pm I was still going well so decided to push on, by 11:30pm I was close to the end so kept going. The build process and photos can be seen below. Total build time was 2 hours to sort the parts and just over 6 hours to build. This was working at a decent pace with a few drink breaks and me needing to get up a few times to stretch my legs and back.

The build process goes like this:
Rear Chassis
Front Chassis
Lifting Arms
Rear truck body
Rubbish Bin

The features include:
- HOG (Hand Of God) steering via a knob on the cabin roof, this works well enough.
- Fake inline 6 cylinder engine, this is the first time I have seen a engine built like this, it suits the truck well and fits nicely in the cabin.
- Bin lifting arms, these work well but are something I am planning on making some changes to when I start MODing this set. I think the small lever to flip the bin back in to the rear body is not needed and I can come up with a better way of doing it. This will be important when I look at adding Power Functions to it.
- Rear Opening, this works via a knob on the top of the rear body and uses a small LA to open this. Again this is something I am going to look at changing to be able to add Power Functions.
- Compactor, this is a very cool design and works well to push the rubbish out.

Overall I am very happy with the truck. It looks good, almost to model team level of detail in some parts. The build process was enjoyable, pre sorting the parts helped a lot with this. You end up with a heap of left over parts which I am going to use for some MODS to this set. I have not put on any stickers, not until I have finished MOD'ing it.

42078 Mack Anthem

I have just done a pre-order of this, it should arrive by the end of the week. I look forward to a busy weekend of building the B model.

My plan for MODs to this so far are:
- Changing arms to work in one step.
- Changing the rear to open automatically as the load is pushed out.
- Add Power Functions for the above.
- Build some new / different bins.

Coming Back

After almost two years away from the LEGO Technic hobby, I am getting back in to it.

I hope to be sharing my MODS and MOCS soon.

MTAS Attachment - Cherry Picker

My second attachment for this is a modified Unimog attachment cherry picker. Originally this was built to mount on to the back of LEGO Technic set 8110 - Unimog. I have modified this to mount on to my MTAS truck, this required a redesign of the mount, removal of the turntable control and redesign of this to work on the new mounting standard. The black control on the side raises and lowers the cherry picker, the grey gear on the rear rotates the turntable.
