Project Mini Hägglund

[Steinbruchsoldat]

Finished parting out the Justy yesterday. Here`s a pic of removing the rear axle:

Made a roller stand (?) for my saw:

Also a jack stand for some welding practice:

Will pick up the steel tomorrow, so i`m going to have the first track assembly ready by Saturday...

What i`m looking for is some information about the controls. Steering is with a steering wheel. Is it possible to lift the rear car? There`s a hydraulic ram that looks like it controls the up and down movement...

The hydraulics only work from side to side. Maybe what you saw was a damper? I was trained on these in the Army in the 90s. From what I remember the controls were steering wheel, throttle, brake, automatic gear box, handbrake and hi/lo range.

Thanks for the info... :ylsmoke:

Couldn`t get the steel today, maybe tomorrow if i`m lucky...

We started making a hole in the wall for ("thing that evacuates welding fumes" how`s this called?):

Also made a stack for shorter pieces of steel:

What i need now is an idea what to use for the turning connection between both cars. There`s the up and down and the left and right movement between both cars. I already designed the joint for that. Now i need a joint that is able to turn around itself and fitting a driveshaft through it. Something like the "thing" that`s between the upper and lower part of an excavator and allows it to turn...

Fume Exhauster. Unless you're just sticking a fan in the wall. Then it's an exhaust fan.

Thanks for keeping us updated on your progress Steinez. The shop is looking great :Wow1:too! I think we need to get the guys from the television show, extreme 4by4 to make a trip to your shop and shoot some footage. That would diffidently make for some worth while viewing!

Thanks for the english lesson. I think it`s a fume exhauster:

Also ran a air hose down in my shop:

I didn`t get the steel today, so i got the axles ready. I`m going to use the rear axle in the front car and the front axle in the rear car. The drive sprocket fit`s perfect:

I`m going to finish the front car first and make a simple skid steer mock up with the parking brake, so i`m able to test drive the front car itself...
I also decided to get a small trailer to transport the front car. The rear car will go in my van...

 

[Steinbruchsoldat]

Came up with a new design for the joint between both cars. It`s based on the real one and should be a lot better than my old design:

Finally got my steel today:

And started over:

Unfortunately it warped while welding, so i have to cut it off and redo it tomorrow...

 

[Steinbruchsoldat]

Redid the part from yesterday:

Then i started with the second one:

Both finished:

 

[Steinbruchsoldat]

Figured out the final dimensions and engine position today. Also shortened the drive shafts:

Then i started with the frame:

And started machining the second drive sprocket:

That looks like it is getting there. I wish I had the time to work up my welding skills.

Subscribed. Keep it up.

Excellent:Wow1: progress Steinez, you certainly have been busy. Is the tire with the disk brake in the photo from your scooter project? Also, if you are welding thick plate steel you might want to use your arc welder instead of the mig welder. It will give deeper penetration and make for a stronger weld. The project looks nice and you can really get an idea of how its going to work now. Good job!

I just took the time to practice welding. That saves me time afterwards when there's no need to clean up the welds...

Thanks. You're right, i borrowed those wheels from my scooter. The right ones should get delivered today or tomorrow...
My MAG welder is more powerful than my ARC welder. It got the right amperage for this thickness of steel. Also I'd choose MAG all the time over ARC. It's just a lot more comfortable to work with...
