Lanz Bulldog D8500

When I saw Miniart was coming out with this kit a few months ago I just really wanted it. It finally arrived on my doorstep on Friday and I figured why not jump in. There are not that many parts for a Miniart kit but it is still challenging and fun.

Made by Lanz of Mannheim, Baden-Württemberg, Germany it was a 3 speed 10.3L single cylinder powered tracto rated at 34 HPr. The engine could burn almost any fuel even waste oil. From what I can find online and Youtube etc it had 1 instrument which was a rotation gauge so you knew the engine was turning the correct way. When looking through the instructions I was a bit confused that the steering wheel can be mounted in the cab or on the right side of the engine after opening a cover. While watching the following video I found that the wheel was used to start the unit and then reconnected to the steering linkage.

The tractor was portrayed in German comics as being cool as that was the sound it made.

The kit also has an extra side which makes me think you can do a later model more powerful version which was 54HP. Parts are also laid out so that I can see some other versions coming. I found one picture of a military version which would be cool to see.
I found a cool cutaway of it online also and this is for discussion purposes.

Construction is fairly simple and the parts fit is pretty good. Miniart does use a softer plastic so it is both easier and harder to sand.
I drilled out the valves and plumbed them in with wire. The drill was .03mm. The colour scheme at the end shows the plumbing and you can find it online also. When cleaning up one of the linkages I managed to break it off as it was so small and fragile. I glued it back together and then when gluing something else it snapped in a new location. So cleaned it up and used some brass wire. For some strange reason the tow pin was molded as part of the pintle so cleaned it up, drilled it out and used brass rod for it. I didnt like the seat spring so I wrapped some brass rod around a plastic rod of suitable size. Then I removed the rod and cut 2 disks off. These were glued into each end of the spring and then the spring was glued in place. Pe cover plates were folded as per instructions and installed. Now a short break before I get back to it.

Nice, looking forward to seeing how this turns out, always love something a little different :)
 
Nice James, glad you're getting bench time.
Single cylinder? Don't think I've ever heard of such.
 
I was hoping I had the correct paint in my collection but no such luck. I did find one that was close though and added a dark blue to make it closer. I think it looks okay. Wheels were a pain as they are so intricate. Tried an experiment with the exhaust stack. Following a tip from Bob Letterman I painted the exhaust and then immediately added some pigment and then gave a light dusting of paint again. While my wife was looking at makeup I found some jars of brownish powder and bought some to experiment. Sprayed Tamiya hull red on exhaust and then used a q-tip to apply the powder. Then dusted with hull red again. This gave it a nice look and a slightly rough texture. Still lots to do. Also some pics of the Meng Fokker DR Is I'm building for my grand kids.

Is anyone interested in more posts by any chance? If so I'll continue.

Why would you ask if we want more posts? Man, your work is sensational! That technique you did on the exhaust looks perfectly real. Most impressive!

So: YES!!! bring on more posts!
 
lol. Sounds like a plan Bob. Looks like I have the rest of the week off so see what happens next. Have decals to install today and then paint the radiators. Then the hard part, weathering.
 
When i was a kid my sister was building her own house and they had a single cylinder dumper truck. Brilliant thing. I was basically a 700cc single cylinder diesel with a massive heavy flywheel that once spinning made the whole thing almost impossible to stall. Years later i was importing old ex army moto guzzi single cylinder bikes. These were 500cc and again had a heavy flywheel and so would tick over at about 200rpm. You could count the firing strokes at just over 1 a second. :) There is a lot to be said for heavy flywheels and inertia :) unfortunately the flywheel is on the other side ...

Crazy glued the wheels and blocked so they would be straight. After a while picked up and the back wheels fell off. Annoying. So used the revel glue and installed and reblocked and now they are on. The yellow on the plaquard did not work out so repainted last night. Today sanded it and looks good but of course i sanded the nose also so must touch up. Installed the steering wheel and need to finish painting it. Used brown wash and dirtied it up some. Now its just a bit of dust and dirt and it is almost finished.

NEAT! that big funky flywheel on the side makes for a neat startup, LOVE the way some German engineers decided to use the steering wheel as means to start that big ol' husky boy
