Project Mini Hägglund

[Steinbruchsoldat]

From the sound of things, I assumed you either put in a larger fuse or a larger breaker without upgrading the rest of the circuit to handle the higher current. However, if your father is an electrician, I'm sure he knows what he is doing and the circuit is designed appropriately.

Carry on!

We put in new breakers that shut off slower. Same amperage but other characteristics. When the motor starts turning it needs a lot more power than to keep it turning and this pike is what kept blowing the breakers. With the slower units it works just fine...

Finished up the motor mount and belt tensioner:





Then the sanding belts arrived:



Looks like i got it right:



Because of this i was able to start the sanding belt tensioner. First mockup:



Making the parts:





Mockup:



Finished:





Wired everything:



On it`s new home:



It ran like a charm on the first try. I`m really happy with it, it has a lot (too much) power and removes stuff quickly. Just what i always wanted...

No it`s time to carry on with the sanding disc...

I've done some fabricating in my shop and worked in machine assembly in college. The time that it takes to build the projects that you have is amazing. Nothing but high quality from what I've seen.

Where do you find the time? I assume that your thread updates are done in relative real-time. When I see your progress from one post to the next I wonder...when does he sleep...eat...socialize?

Are you going to include some sort of spark/dust collector system on your grinder? Besides being messy sparks in the air are dangerous and unhealthy.

Keep up the inspiring work!

^^ What he said! I am amazed as well as I have gotten myself head high in projects. Mostly desert toys. Keep up the great work. I want to be like you "when I grow up!" LOL!

Man, I wish you were my neighbor!

Thanks. The updates are real time. First thing i do when i come out of the shop is to upload the updates. It`s all about priorities, i`m working every free minute on it. It`s like 8h at work and another 4-6h in my shop every day...

While building the beltsander i had some time to rethink the Hägglund. I just didn`t like the chains and decided that i`ll start over and build a transaxle setup. Rotate the engine 90 degrees and put a differential up front and one in the rear car...
Give`s me also a great gear reduction. Top speed is about 20mph in 5th... It also give`s me a vacuum activated pto, ot sure what i`ll use it for. Maybe a hydraulic pump for additional stuff that`s not needed while driving...

Starting over tomorrow...

Sad start today:





But this will just be better:









A few thoughts:
The engine will stick out a bit more on the rear, but this will be covered by a hood. Should look similar to the fuel tanks on the BV206. Because of the driveshaft i can`t use my tank anymore. This is what bothers me most, but maybe i can make it work somehow. I should be able to squeeze the seat a bit more backwards over the transmission. Should give me back a bit of the legroom that the diff takes now.
The shifting linkage will be a lot easier, just unusual because it`s rotated 90°. I can also move the wiring loom to the right so i can get in from the left. Simplifies things a lot...

I also did the math on the final reduction and speeds (km/h):

That is quite the CV angle

And now instead of sitting on a gas bomb, you can keep things interesting by straddling a spinning drive shaft

I'm sure your new design will be better. Shafts are almost always better than chains. Keep up the good work!

They will be almost straight when finished...

And now instead of sitting on a gas bomb, you can keep things interesting by straddling a spinning drive shaft

Will be a lot more interesting: I`ll be sitting on the gas tank, on top of the drive shaft...

Steinez, I need to know why the sudden change over to a driveshaft and axel system. Is there something I dont know? Secret footage of chains coming off at 7000 rpm? Just kidding. Your progress looks excellent with the tools and the Hågglund! But tell me, how are you going to transfer power to the rear Hågglund unit now that you are using the hook up for the forward Hågglund? Ahh you have so many secrets Steinez...
