    So, What Have You Done Today?

    in General discussions

    Posted

    Clearing the Juggernaut's body from its blue paint using Tamiya paint killer. 

    The inside of the shell only has a light spray of paint and comes off easilly, the outside has a much thicker layer and requires more elbow-grease.
    About half-way done with the cabine after one hour. So plenty to do for the rest and the pickup-bed.

    The big bearings arrived and the normal/small ones I have on stock, so I can always switch to axle-rebuild. ^_^

    Hoping there is some time to visit the LHS this weekend to get some plastic sheet materials.

    Some mock-up on the Juggernaut.

    What I really want is a longer dual-cabine and shorter bed, so 'liberated' some cardboard from my wife's crafts hobby to get a feel for the dimensions. Looks like shifting 1 inch from the bed to the cabin will give the right proportions.

    Also tested the paint killer, to check if the blue can be changed. It comes off very easily.

    Future build thread…?

    Very far future, so many dreams and unfinished cars.... :lol: A teardown thread maybe to see what it is that I have and what it needs.

     

    But I now realised that it's been a while since I did any RC stuff, so I took Bullhead-Clod Big Bear off the shelf to see what body damage needs repair.

    Just needs some glue to the grille, and new body posts, so I have the 3D printer fired up to make those. It also needs rollbar spotlights. Will see if a 3D model exists somewhere.

    This weekend is my first weekend without any 'must do' from my wife. :lol:

    I've been planning to install the reversing camera in my (full-size) car, but I cannot find the camera anywhere as it's a small box between many other stuff in the garage. :wacko:

    But with the colder seasons coming rapidly, insulation DIY is taking priority with today's energy prices.

    Need to measure up some old dual-pane windows in the kitchen, so I can order modern HR++ dual-pane glass to replace the old stuff.

    And check out some areas on the house that need insulation improvement.

    Promised sister in law that I would do some electrical work.....

    There is always something that needs painting....

    When you are a home owner, you are never bored. :lol:

    Had time to work on the tank chassis that I use for robotics.

    1pD4CNn.jpg

    Took out the 80T 540 motors as they had little torque at low voltage and too high speed at max voltage to my taste.

     

    3D printed a drill template to drill new holes for the 800RPM gearbox-motors.

    This allowed me to drill new mounting holes for the motors.

     

    3D printed an adapter ring for the motors to sit nicely in the middle of the original shaft hole.

    And the new motors sit perfectly inside the gearbox. Happy with that.

    Checked the top speed, it is about 0.5km/h. That's perfect for a robotics application. ^_^

    Busy closing a deal on an NOS set of Marui Samurai gears for the rear gearbox.

    Hope this is a better deal compared to yesterday, when I bought a used set of PC speakers that I really needed, and when I returned home I found a set of PC speakers sitting in a closet... :wacko: I've got too much stuff I know...

    Marui cars? which ones? :)

     

    A Big Bear that needs a body, chassis is done.

    Galaxy RS in pieces, needs rebuild but I have everything.

    Ninja, complete.

    Shogun, complete.

    Samurai, in progress.

    Golden eagle, complete but needs a driver.

    Basher-Bear, Bullhead-bear and Frankenstein-Bear need a place too.

     

    Edit: forgot M-05 Bear, enough parts for a 2nd Bear, and plans for a blazing Star based Course Melling Thunderbird.... :lol:

    More Samurai work on the wheels.

    The Hotshot tires fit on the front wheels just fine. As I have a new front wheel set, they only needed to be glued.

    For the rear wheel set, I re-used the wheels that came with the car.

    zVs47Gu.jpg

    The left wheel is as they are after clearing away massive amount of CA glue. It looks half-decent but has a badly damaged front edge.
    The right one is the same, but here I sanded away the lip to get a smooth cilindrical wheel.

    Next: I 3D printed 2 new edges, and inserts to get the rim inner diameter to match the hotshot tires, and glued them to the rim.

    i3P3nLj.jpg

    A dash of silver paint is on the front to get it to look somewhat original with a small silver lip.

    The rear wheels can now accept the hotshot tires, and (from a distance) still look like smaller diameter rear wheel (right) compared to front (left).

    One rear wheel done except for glueing the tire, now some more 3D printing for the 2nd.

    Well the tracking data was off, as the big box did not arrive (didn't expect it too haha).

    But is was 2 bubble envelopes with the Marui Samurai's ESC and 2 pinions that I intend to use for the tank chassis.
    I also already got geared motors, and if my calculations are correct this tank chassis will move at a lightning earth-shattering speed of: 0.13meter/second -> 0.45km/h. :lol:

    I'm not in state right now to mount my Samurai and post pictures of the G55 parts printed and in condition, so It would be great if you post a make in Thingiverse :-D. That's the first time I'm publish something untested as finished on Thingiverse, but it was quite simple, so I did not bother to test it (could not, as i'm still awaiting parts for my Samurais). Great you confirm it works :-D. Thanks :)

    Made a thingiverse account but for some reason sign-in does not work correctly... Will try again another time.

    Currently working on my 'new' 386DX-40Mhz PC, so the samurai is om hold for today, but I have the 3D printer set-up for some more parts tomorrow...

    So, more work done today.

    Printed the G55 model from  @silvertriple . Replaced 2 wrong sized screws for the chain adjusters to the right size.

    Got up to step 18 in the manual, both gearboxes installed. The drive train runs smoothly on a bench power supply so job done so far.

    Crazy part is that I seem to be missing a lot of screws... Not sure where I put those, maybe I lost something in the years it was stored away..
    Luckily the Ninja and Shogun have a lot of left over screws, so I can continue for now.

    I also don't have wheel bearings. I came across an unidentified pack of 11/7mm bearings, so I made a order mistake I guess.

    Ordered bearings 10/6mm, an ESC and some motor wires. To be continued.

    For a while, the 3D printer has not been printing as nicely as it did some years ago.
    The problem is most probably absorbed moisture in the spools of PLA plastic that feed into the printing head. I'm not storing those spools the correct way in an air-tight bag with moisture absorber.

    I had already bought a food dryer, and have now gutted out 2 trays so a spool can fit inside.

    Now leave this spool to dry for 5 hours, and test print again after dinner to see if this has indeed improved quality....
