    The window rubbers look good, how did you do that if I may ask?

    Thanks! In my head, the idea looked better but I’m satisfied

     

    The rubber is like the insulation of electric wires. The real use it’s holding small trees and such. It’s sold in 200m rollsIMG_20180812_110951

     

    Basically, dragged a x-acto inside it to split and glued to the “glass” with small drops of cyano glue

    I think it’s possible to do with electric wire. Pulling at one end, splits the insulation easily

    Haha, excellent – I’m using the same idea for my D90 back windows but I glued the rubber around the frame and I’m now wondering how I put the glass in without it being recessed 2mm or so.. I didn’t even think about surrounding the glass rather than the hole.

    I’m guessing it will be tricky with the curved windows but I’ll see what you do with them first!! 🙂

    Many thanks!

    Yes, the curved windows were tricky. Had to use an heat gun to wrap the “glass” around a tube but the radius was not right

    But i didn’t want to repeat the process and went with it

    Because i couldn’t use the same idea for rubber, did a paste with putty and black paint and applied around the window. Don’t look as nice but fill the gaps and it’s better than nothing 🙂

    Not really an update but modded my tension wheels . The problem is that sand and dirt seems to stuck between the tension wheel and tracks and make the tracks slip off the wheel entirely.

    So, a couple holes on future wheels should improve something:

    In the meanwhile, I’m waiting for a break to finish the last 2 windows

    well,too much time without updates. M548 was nearly considered done, only needs the smoke generator fitted and paint the hull but there’s something more important.the henglong gearboxes are not up to the task.I’m already on the second set.

    Working on new system using these gearboxes:

    Ordered a 30:1 to test

    Thought of machine the structure but 3d printing could do the job

    First of all, I’ll not say that this was my original creation

    There’s a german shop( https://www.modellspiegel.com/) who created and sells these gearboxes for 1/16 tanks:

    I had several ideas for the new drivetrain and the chosen was heavily influenced by this layout above

    But I the time, I’m not in condition of forking out all that money and also like to do things myself as much as possible

    To the build,this is where it sits now:

    Tomorrow will do a test trial to see if the ratio it’s good or not, and then order the other gearbox

    First trial of the setup on 3s. It’s so good when things work at first try. Unfortunately, the gearbox it’s too fast(33:1,actually), I’ve already ordered a slower one. The only bad thing was that the bores on the gears are a bit off center, that’s why it sounds that way

    Good news everybody!

     

    Things have been quiet but I’m working on the new transmission as parts arrive.

     

    The test 33:1 gearbox was been replaced by twin 56:1 gearboxes and got the right pinions so was a matter of making the shafts, spacers and assembling everything

     

     

    The transmission structure will be replaced by a V2 version that fits better on the hull, that’s already printed

    I thought the truck would be ready by now but I’ve had a few setbacks. For now, I can show you the drivetrain working outside the m548

    It’s not a feat of engineering but I’m pretty happy with it. The old one was loud

    there it is,assembled and working. Just need a cover to reduce some noise and prevent that some LED wires don’t get caught on the gears. The electronics are not in place because I’m about to take everything out to paint the hull

    There’s some video.Sorry about the background but I can’t go to the woods right now

    Dollhouse stuff:

    Thought that the operator needed some goggles for his helmet. The first idea was to scratchbuild everything but my Dremel broke so I’ve copied the goggles’ frame from the real army model and 3d printed it.The lens are from a bit of clear package plastic and the strap is a strip of bicycle inner tube

    First pic another cheer up moment, fingerbob with goggles, great. Loving this build.

    Thanks. I tried to do the things as real as my skills allow but in the end, we are grown men playing with toy trucks :). Has to be fun

     

    This one has been delayed for a while, more than a year. Have the mounts in place, the tools but didn’t found anything suitable for making the straps to hold everything

     

    When doing the strap for the goggles, remembered to do this and the rubber strips do the job well
