Quadrotrac

[Steinbruchsoldat]

Plunged the second o ring groove:

Chamfered the tube:

And welded it. Also with three beads at the backside:

Turned it down and chamfered it:

Also chamfered the tube:

Some beads later, nine to be exact:

Also reamed my tailstock with a cone reamer to refinish the broken cone:

Wow:Wow1:some really high quality manufacturing you got going there Steinez. We got to get you to Canada soon so we can build some cool rigs...:ylsmoke:

 

[Steinbruchsoldat]

Then you better start building a shop and get some nice metalworking machinery. No, serious, i should have time to go with you next year, if i'm still welcome...

Here's the vid from yesterday:

 

[Steinbruchsoldat]

Mocked up the articulated joint:

Cut the rear part:

Some thoughts:

First front mount:

Welded:

Rear joint mount :

Everything together:

 

[Steinbruchsoldat]

Built the missing mounts:

Then i started fabricating the ram mounts:

Didn`t like how they came out, gonna redo them tomorrow...

 

[Steinbruchsoldat]

 

[Steinbruchsoldat]

Started building the ram mounts today:

Looks good:

First set finished:

Needed to bore those parts out. Couldn`t use my mill with the boring head because it`s to big and wouldn`t fit on the table with the big angle plate. So i had to mount the four jaw chuck on the lathe and bore it out. Unfortunately one of the former owners of my lathe messes up the chuck flange pretty bad so it takes me a long time to change chucks. Because of this i thought out something different:

While this was cooling i turned the bolts for the ram mounts:

Then i put it in the lathe:

Finished:

That`s the whole thing:

The i made the second set of ram mount parts:

Tacked them together to bore them out. Should have tacked together all four:

Was quite a bit interesting to set it up in the four jaw:

Drilled it:

 

[Steinbruchsoldat]

Because of this setup i couldn`t spin it fast. I only have carbide boring bars and they don`t like cutting speeds this low. So i found an old boring bar i braced on a piece of HSS and now i ground it and it worked flawless:

Boring it out:

Finished:

The puzzle`s finished:

Then i put the next piece in the four jaw:

And started drilling it:

After Chilliwak in Canada, then straight to Kauai with Wainiha right?:sombrero: Teach me some skills. You are really good. Not just the mechanical side with tools but creative problem solving.

 

[chilliwak]

Well Steinez I have just found a new name for you, `Double Chuck´ !!! Who would ever thought of mounting 2 chucks in their lathe like you have? When you talk about going to Canada are we talking 2015? I also have a plan about doing some work in Canada if you want to hear about it. I can certainly see that you now meet my expectations for a machinist or fabricator. Cheers, Chilli....

 

[Steinbruchsoldat]

Ok, mister double chuck talks about 2015. He also want`s to hear about your plans. Btw., that`s a cool name, not as good as Chuck Norris, but still good... :ylsmoke:

Bored out all the holes and finished all the part`s for the articulated joint:

Had to turn the second lock nut first, otherwise i would have to lift the whole articulated joint in the lathe to check for thread fitment:

Probably going to press a driveshaft carrier bearing in this part too, but not sure about this. But the thread is finished, can do the other stuff later:

All the parts for the articulated joint:

Mocked up the first parts:

Tacked on:

Tacked on the swivel heads:

Put a new belt on the belt sander. Didn`t notice it was sanding slower, but with the new belt it`s a beast...

Ram mount tacked together:

First one:

With the ram:

Second one:

On the vehicle:

Btw., a buddy of me owns a quarry. Since last year Liebherr is testing their heavy duty dumpers there. It was his birthday today, and i talked to the Liebherr engineer who is the supervisor of this testing. He said he will send me a guy with a trailer to pick me and the Quadrotrac up to test drive it there. Now i just need to finish it...

 

[Steinbruchsoldat]

Cut the threads from the rams:

And tacked on the universal joints:

Turned some bolts:

When i`m cutting with the holesaw i always keep the cut out piece:

Just turn it down:

Make`s a great lock for the bolts:

Mocked uo the articulated joint:

Had a hard time figuring out how to mount the rams:

Now i`m getting about 38° of steering, that`s even 4° more than a Hägglund.

Then i started reinfocing the frame where the articulated joint and the rams attach:

Then i started building the first ram mount

Also got those three hydraulic motors. Anyone has a idea what to use those for?:

 

[Steinbruchsoldat]

Started building the rear part of the driveshaft today, to make sure the pivot is aligned. Cut the flange first:

Then welded it up:

Turned it down:

Drilled it:

Bolted it in and aligned the pivot:

Cut the mounting rails:

Tacked on the first one:

Tacked on the ram mount, to make sure there`s no interference:

Looks good:

There will also be flat stock on the bottom when it`s off the table:

Made the second ram mount:

And finished the other side. Need to buy some more flat stock:

Will be tied into the cage later:

 

[java]

Cant wait to see it done.

 

[Steinbruchsoldat]

Cant wait to get it done... :ylsmoke:

Started to mount the last thing to the pivot:

Made some mounts

Tacked them on:

And set it.

Like this i get about 48° articulation, for comparison, a Hägglund gets about 34°.
