@@ryanhahn7251 I was telling my gf about your very clever steering system. Mine will be taken to shows as it will have a diesel punk/apocalyptic theme to the exterior.
Ohhh ok, so this is basically using Torque converter's right? I think that's what they are called, They can usually be used in go karts but since there is no wheel steering you need 2, since 2 tracks
Yes, similar to a go kart converter. Except in a go kart, the rpms and load on the engine determine the pulley diameter. On this tank, you control the pulley diameter with the steering tillers.
Yes I considered that and sketched some ideas. It would have been a bit more complicated to fabricate. I made a fairly simple modification of the FNR shift lever from the lawn tractor. There are a lot of less than ideal ergonomics with this tank that I would like to have made better. But this was built not based on what features do I want, instead it is what features I can complete in time for my July 4th deadline!
I welded one of the differential side gears to the main spur gear, effectively locking the two axles together. But this way, I could still replace an axle shaft if it got bent or broken.
@@ryanhahn7251 Thanks for the fast reply. I want to build a scaled tank too, my issue is drivetrain. I want to have a bit more torque and power, Im unsure if belts are strong enough with a ~50hp engine. I gotta do some more research I guess
@@chrissi.enbyYT 50 hp is a lot! In my real vs replica video I pointed out that my replica has a power to weight ratio almost double what the real tank had. My replica was geared a lot lower than it needed to be. With a bigger crank pulley I’m sure it would have done 15 mph on level ground.
@@ryanhahn7251 Im trying to rebuild the German Wiesel 1, funny cute tank. It has originally 80-109hp at around 3 tons or so. With heavy tracks and engine I estimate around a ton, roughly. Easiest would probably be 2x 14hp air cooled engines, one for each track? Idk. Thanks alot brother, so much to consider. You might be right, but the Wiesel rips IRL! Some japanese guy used hydraulics but those systems are unaffordable for me
@@chrissi.enbyYT one 14hp drive train for each track would be the most cost effective way to go and I think would give you plenty of power for a 1 ton tank as long as it’s geared correctly. My solution using one engine and two transaxles worked but took a lot more engineering. TinyTank428 did several hydraulic scaled tanks. Hydraulic drives are reliable but much more expensive and give you a very small range of speeds because they become very inefficient outside a narrow range. Good luck, I hope to see your tank someday!
You did very good can't wait to see it actually run.
Thanks! Me too!
Looking forward to the next steps. At the end you swap the engine to a stronger May be 3 Zylinder 50HP...-;)
Can not wait to see the actual test run. You are doing a brilliant job. Tiger tank next? 😁
Thank you! I’d love to build a Tiger. I just don’t have a place to store another tank 😄
Looking really good.....
This is amazing great work!!
Thank you!
Great job
Thanks! I just viewed your videos, you have a nice tank too! Mine is mostly for show, but yours appears to be really functional.

Have you thought of using some type of foot pedal operation to change F/R so that you don't need to take your hands off the "speed controls"?

What did you do to the inside half of the lawn tractor axles? Did you wells them together?
I welded one of the differential side gears to the main spur gear, effectively locking the two axles together. But this way, I could still replace an axle shaft if it got bent or broken.
The price of plywood now might prevent me from working on mine😥
Did you see my Ha-Go build? Much cheaper way to go!
@@ryanhahn7251 yeah the ha-go looks extremely nice, i want to go a larger route just so i can do more with it
Whats the power of your engine?
12.5 HP
