Mounted the fuel pump and catch tank:

And the filler neck:

Coolant tank:

Next is the articulated joint. Tried to figure out some measurements:

Didn`t work out, so i thought something out:

Made an adjustable test joint:

Finished:

Still have no idea. Looks like the rams only fit in one position, but i don`t have any idea how to figure it out. Would be great if someone could hack it in cad and probably come to a solution.

That mini bender is slick. I'm stealing that idea. Thanks for sharing your skills with us.

Yes, it`s pretty usefull when doing fuel and brake lines...

Started with the articulated joint today. :

Cut the first part:

Turned two bearing seat`s in the outer part:

And started with the inner one:

I really like the way things are coming together Steinez. I honestly did not understand much of what you said in your video but I can get the idea of your work as it progresses. Obviously you have things thought out and you have a clear idea of what you want to do so I am just going to sit back and enjoy the updates and pics you post. So cool to see the Quadratrac come together. Cheers, Chilli...

Thanks, i guess you can see what`s going on without understanding much.

Started fabricating the ring that goes on the inner tube and holds the bearing and seal. First i cut a hole in it:

And welded it on:

Here`s the vid from today:

Thanks for posting that last video Steinez. What a great way to spend an hour saturday morning watching the step by step process of how you build that unit. It really shows how much work that goes into making each piece and also your attention to detail. I thought the best part was when you came with a laugh at the end of the video when everything seemed to work as you planned. Great work. I am looking forward to the next instalment and update from Redneck Engineering....:Wow1:

Thanks Allan, nice to hear that.

That`s a mistake i make everyday i work on it. I always think, oh well just turn that down, cut a thread there and it`s finished. Yeah, not really, it really takes a lot of time to make all those parts...

Found the lost part of that video today:

 

[Steinbruchsoldat]

Bought steel for the rams mounts:

And started with the first locking nut:

 

[Steinbruchsoldat]

Machined the first locking nut:

Turned a groove for the o ring:

Together:

Turned this tube:

And started with a flange for it:

Here`s the vid from yesterday:
