    hi,

    today, the most difficult part of the cylinders are done. The front seals.

    Turning inside is like blind driving. For me a new experience and very exciting.

    H06078

    Two accurate steps. One for the seal, One for the support ring.

    H06079

    H06084

    The front hole fits the piston.

    H06080

    The actual tableau

    H06083

    Hi,

     

    some steps later I‘m almost ready for a first Testrun.

    All works smooth but just one incontinent cylinder prevents me to drive.

    A little preview from the mounted car with his cylinders and the actual a bit confused tube-setting.

    Looks a bit massive, but I like it.

    Regards

    A short clip from the first little testdrive. The defect cylinder is deactivated. One cylinder is obviously enough but two will be better in heavier situations then my garden 🙂

    Totally bonkers but brilliant. The machining you have done is fantastic.

    Like the first build you showcased on here, I can see a steam punk theme working with this too  🙂

    Thanks guys.

     

    During the testdrive I‘ve seen , that the locked front-axle is not sooo good for a small turning circle.

    Permanently unlock is a possibility, but a trx4-axle can both.

    But this little pieces of plastics are very expensive. So I decide to try my own portalaxles with switchable locks……..

    Look, you’re new here, you want to impress and you have some serious skills in metalwork and turning. Please realise that this is your first build on the forum – you will (hopefully) stick around and give us many years of great builds, but seriously, how are you going to top this one if you now go ahead an make portals with locking diffs from scratch too?!

    You may of heard about the carrot and the stick. This thread is too much carrot 🙂

    In awe.

    Hi,

    thank you for your kind words.

    To top my work is very easy. I have so much to learn about metal and his handling. I don‘t believe that I‘m find an End of Learning in my Life.

    But that‘s the Story of my Life. Learning things outside the job.

    Before I‘ve entered the RC-World, I‘ve been a good amateur Photograph with an own little studio etc.  ( examples: http://www.ralf-broda.de )  but after the 100th nude- session or stills-arrangement I‘m getting bored because I don‘t learn anything more.

    At metalworking I learn new Skills every single Session in the shop.

    And you dont need to be afraid, that I will have sometimes no more Ideas for a new project. For example a short abstract of my looong list of possible Rigs:

    – Real amphibic car with an outboard motor.

    – rebuild my foremost oil field truck in a more scalic way. Kardans instead of moas, hydraulic steering instead of electrical and so on.

    – uniknick. A articulated Mog. same concept like the trialcar but more scale

    ….

    ….

     

    Will this rigs tops the trialcar? I dont know. But it will be the same fun to build them.

     

     

     

    Regards

    Ralf

    Beside the ESC (eifel scale challenge) I took the chance to ride a first trail on more realistic conditions than in my garden. 620EBE75-4EED-4551-9D96-B9EE9E7BB3ABB9636F2B-B80D-47DD-9DD8-24212FA1865651514BC3-2480-4649-93BF-5D4F4007A1B315E2AD06-1E0E-4432-BA44-827E964D639E118CA8CD-3A02-484F-A393-E04DEA7BB109

    The  steering geometry is very unusual and I will need many session to learn to drive foresighted.

    Hi there,

    during a 35 minute session on the open trails of the esc I‘m happy with that rig.

    But the turning circle is realy bad. So I think and plan and discard and think and…..

    But now I have a final? 🙂 Plan for my axles.

    With this unusual design I get the diffs in the same height as the transfer-case. I still need kardans but they can be very short and I can set up the wheelbase in a great scope.

    The lockable diffs needs some crown and bevel gears. This sort of gears I can‘t build by myself. So I‘ve ordered parts for two lockable Diffs from trx4-axles.

    The rest of this double-portals will be handmade.

     

    Stay tuned …..

    Regards

    Ralf

    Ah ok, it’s nice to know you are a mere mortal like the rest of us 😀

    Double portals? Wow, you certainly won’t have any clearance issues between the wheels. Very interested to see the production of this.

    The first diff-shell.

    Some steps including two bearing fits. Diameter is 40mm. A little bit less than the old scx10-diffs.
    H06093

    The hole for the locking-excenter.

    The little hole is for the bevel gear flange.
    H06095

    The great hole for the bevel gear.

    Hi,

    today I‘able to solve a big Problem for my rig and my Brain 🙂

    The question was, how I can build the bevel gear flange with a spigot without cnc?

    Solution: In one piece? No way. But in two pieces. How can I connect the two pieces?

    Just with a thread. In this case a M20x1 thread.

    ….. aaahh, the pics are not on my phone. So:  pictures coming …. 🙂

     

     

    Regards

    Ralf
