Quadrotrac

[Steinbruchsoldat]

Thanks. Sometimes i should just go the easy way...

Noticed that i need to build the front hydraulics first so the winch line does not interfer with it. I reuse some Hägglund parts, but i had to cut some pieces of:

While the saw was cutting i cut the steel for the "legs?":

Then i milled the mounts flat and put some chamfer on:

Finished:

First leg mounted:

Made the second:

Both tacked on:

Measured everything and tacked on the connection between both legs:

Will also be able to mount two of those plates to act as a anchor for the winch:

Here it is all the way up:

I may have asked before. Is this your home workshop?:drool: If so I'm not friend anymore

You never cease to amaze me.

 

[Steinbruchsoldat]

Ok sorry my "not" friend...

It's all mine, payed with my money. And yes it's at home. A little bit (read: ways) to small, but you have to take what you got...

Julian,
Have got a ball park figure on final weight?

 

[Steinbruchsoldat]

Hi Jay,
to be honest, i have no idea. What i`m guessing is something about 2000-3000lbs. But you know, weight means traction, right?

Welded up the rear ram port and drilled a new one:

Tacked the shortened rear mount back on:

Tacked the front eye on:

Started fabricating the ram mounts:

Drilled them:

Bored them out:

Mocked up the lower mount:

Tacked it on:

Upper mount tacked on too, ram all the way down:

And all the way up:

Cut off the winch mount and made some changes:

Tacked back on, way better than before. Don`t know why i didn`t do that the first time:

Started building the "thing that guides the line". Don`t know what to call that in english, it`s called something like "line trumpet" in german. First i bored out a chunk of cast iron:

Roughed out:

Finished turning:

Polished:

Flipped it around, faced it and chamfered it:

Here`s how it`ll be mounted, lines up perfect with the winch:

Also got the heater unit:

Could probably be mounted here:

Any suggestions on where to mount it? Mount it up high so it doesn`t get wet/flooded? Is there a need for it to blow directly on the windshield in order to defog it? Is there a need for a fresh air connection to the fan? Cab won`t be sealed anyway...

Found out that i need a second fairlead in order to keep the line away from my feet.

Drilled a chunk of cast iron:

Bored it out:

Turned the od down, faced it and put a radius on the inside:

Flipped it around and finished the second side:

Also cut a flange to mount it:

This is how it`ll go together:

 

[Steinbruchsoldat]

Started machining the rear fairlead mounting flange:

Here`s a trick to get hole pattern layed out real easy. Just mark the diameter using a sharp hss tool. The find something to stuff between one jaw and a part of the lathe. Scribe it using the cross slide then turn the chuck one jaw further and repeat it:

Drilled it and transfered the holes using center punches:

Finished:

Then i made the front fairlead mount:

Mocked up. Just need to move the pedal assembly a tad left:

Need to weld in the front panel first tomorrow, but i`m not real sure on how to lay out the hole for the line tube...

 

[Steinbruchsoldat]

Started by cutting of the pedals and front sheetmetal:

Layed the new panel out:

Cut it out:

Tacked it in:

Layed out and cu the hole. Cut it bigger on purpose so the line guide won`t take my windshield out when it`s moving a bit under hard pulls:

Tacked it on:

Remounted the pedals:

Tacked on the rear fairlead:

And started gusseting it:

Here`s the line routing:

 

[Wainiha]

This has to be the most amazing fabrication thread. Am I repeating myself?

 

[JKFlyfisher]

Holy crap this is awesome! I wish I had the space and know how for this stuff, I'll just sit here and watch and be jealous!

 

[Steinbruchsoldat]

Thanks guys. I just dry to do my best...

Gusseted the line guide today:

Then i made the first floor panel:

There`s just enough room:

Then i started with the heater:

Made some mounts:

Then i had some help to make sure there`s no contact with the seat when it go`s up and down:

There`s just enough room, so i tacked on:

Then i glued some plastic to it:

Mounted the windshield defogger:

Then i started mounting the seatbelt:

Didn`t have M11 nuts, so i turned the bolt down and cut some M10:

Finished:

The the glue was dried and i could glue on the outlets:

Made a mount for the windshield washer:

Finished:

Then i finished the heater:

Here`s a total shot:

Will start the wipers next, this is going to be complicated...

Julian,
The fab work is amazing. I look forward to every installment. I can hardly wait to see it in action but then I'll miss the build so you'll have to start another project as soon as this one is finished

 

[chilliwak]

I agree Steinez, wipers can be a huge job...:Wow1:

Thanks. Next two projects are already planned, so there should always be a build thread...

Started building the wiper today:

First i cut the base plate:

Made some mounts for the bushings :

Tacked them on. Was pretty hard because they are at odd angles in all planes:

Put the wipers on:

Made those levers the same lenght:

And connected them:

Tacked on the frame:

Mocked it up. Flat bar represents the windshield:

Turned some bushings:

Made the first endplate:

All parts together:

Finished:

Tacked them on:

Milled the connection rod:

Tacked it on:

Turned the wiper mount:

Everything together:

Here you can see that the wiper always stays vertical which results in a much bigger wiped area:

Then i started with the motor. Unfortunately i had to put the whole wiring loom together to find the rest position of the motor:

 

[Steinbruchsoldat]

Started by making a mounting plate for the wiper motor today:

Shortened the lever according to the desired stroke:

Everything together and aligned:

Mocked up:

View from the inside:

Here`s a short clip:

Then i started building the wiper blade iteslf. First i started slotting a stainless tube:
