Show and Tell / Re: 3d print T34

Good luck with your project. Yes, I've printed several tanks and they run around 400 hours of print time or more. You'll have plenty of time for research!

Wow, that's a really nice T34!  Would love to see some video in action and to be able to hear the sound programming.
Thanks for posting!

That's a good looking tank!

     My apologies if this was posted elsewhere on this forum but I didn't see any reference to it in my search. 
     Just curious if anyone has printed out/purchased a kit version of Warprints 1/16 Jagdpanzer 38(t) Hetzer?  It looks like the the model creator has done some very nice work on not just the kit itself but also the assembly guide, etc...  It looks like the designer is also in the process of designing a 1/16 scale Cromwell as noted on the Warprints Facebook page.
Wow, that's a nice tank! Can't wait to see the finished product! If I didn't have a ton of 1/10 scale King Tiger parts awaiting assembly, I'd be tempted. Next pandemic, I guess!  ;)

Well, the T35 is now complete.  I am currently printing a 1/10 scale King Tiger tank which I will probably start assembling in the fall, as I've returned to an old love of mine, RC aircraft flying.  After being cooped up in the workshop all winter/spring I'm ready for some fresh air and sunshine!

Anyway, here's the latest on the T35

Sehr cool! Du hast gute Arbeit geleistet.

Show and Tell / T35 Outdoors testing
« on: February 25, 2021, 07:12:01 PM »
The weather has improved here in Erie, PA and the snow has cleared from the driveway and walkways so it is time to do some outside testing on my T35.
It is running pretty well although I did have a track displace on the drive gear on the right side. I think it happened while I was driving over the snow at the start of the video. It appears the T35 is fussy about the road surface... much like the real one!

Anyway, please enjoy the video!

Nice job Joe, thanks for posting.  It's good to see that the work continues on the T35.  It will look amazing on the battlefield.  Nice find on the Maestro controller too.
Thanks, the T35 is pretty much finished except for finalizing the electronics.  I've been slowly working on Kim's HECLO TCB hat, but have found a troublesome adversary in the VHN5050A motor driver chips he uses on the board.  I've managed to ruin a bunch of them so far without success, although I just soldered up two more boards that look promising.... the continuity tests will determine the outcome.   Worse comes to worst I will build the boards without the drivers and use the Quicrun 1060 escs I have installed already for testing and use the board for the other functions it offers.

The weather has been crappy so I haven't had the opportunity to get some video of the T35 running outside all assembled and with the guns travelling thanks to the Maestro board.  It really is a wizard bit of tech and reasonably priced!  Because the tracks are so grippy I don't dare run it on carpet inside as the tracks grab and tear apart if I attempt any kind of a turn. The fine 1mm wires joining the segments snag the carpet with gusto.

The weather is improving, so I'm hoping to add to 'show and tell' soon.


Show and Tell / T35 Secondary and Tertiary Turrets controlled by Maestro!
« on: February 07, 2021, 03:00:17 PM »
Since my 3D printed T35 Russian Heavy tank has 5 turrets I need some way of controlling the two Secondary Cannon turrets and the 2 Machine Gun turrets.  The main cannon and Turret I will control directly from my Taranis QX7 radio, but for the others I will control them using a 6 channel Polulu Maestro controller.
Thanks to Dean Rauch for the awesomely detailed T35 STL files available on Thingiverse!

Check out the Maestro controllers at Pololu

Check out my video of turret control on Youtube

I made a Youtube video showing how I modified my turrets to rotate and elevate the cannon.

Okay, I gave it a good try, but  after 7 or more variants of the print in place track with poor reliability, I'm throwing in the towel on that idea.
On the plus side, I did modify the track segment so it could be printed with the guide pin in place, so that was a win, but  I am now assembling my segments with 19 gauge (1mm) steel wire and the wire pushes in quite nicely.  Since I'm no longer drilling the segments to accommodate the larger size wire I first used (1.5mm) the segment hinges will be stronger and the track should be much stronger. Definitely is more flexible.

Well done, very realistic!

Show and Tell / T35 Tank Progress
« on: January 05, 2021, 02:52:15 PM »
I've had some time to work on the T35.  I got the main turret rotation servo installed and working. It required cutting out some of the deck and hull to fit the servo, but not too difficult.  My servo pinion which engages the turret ring kept getting snapped off. I ended up adding a 2mm section of turret as a spacer to allow more clearance.  It's pretty simple in PrusaSlicer.. i just brought the main turret STL file into the slicer and dropped it until only 2mm was showing above the build plate, then printed it. It fit perfectly.

Here's a link to video of the turret test: 

I've also got the side skirts on and most of the superstructure now together and finalized along with working out mounting points for the superstructure sections. They need to be accessible for access to the battery and other electronics, certainly as long as I'm working out the details.  I plan to use Kim's TCB hat for the final control of the tank, but currently I'm just using an 8 channel receiver and the ESS Sense One sound unit as it requires a lot of volume to overcome the super noisy drive train. I know that Kim's design has a powerful amplifier, so I'm sure it will work out, however there's not much room in the hull for a good speaker, especially the Krasi50 gearbox takes up much more room than a Heng Long gearbox.

I put together a video slideshow of construction photos which may help others who embark on this project.  I'll add more photos and videos as progress wraps up.

Hi Dean, started making your T35 about a month ago and have around 60% done. Trying to work out what gears go where at the moment and if any bearings are used lol
Dean doesn't seem to appear much on this board lately. 

I'm building the T-35 too. If you are using the Krasi50 Gearbox you will need a dozen 10 X 5 X 4 mm bearings for the 5mm shafts the gears ride on.  The output shaft will require  four 12 X 8 X 4 mm bearings.  You'll also need 5mm rod, as stated and 8 mm tubing for the output shaft. Krasi included some printed shafts as guides to what the output shafts should look like as they are flattened to firmly mount the drive gear and the track geared wheels.
I also found that the 8mm bearings were not retained well in the gearbox case so you'll either need to cobble up some retainers or, what I did was to hack the case so that the    middle wall is twice as thick where the double bearings mount back-to-back.

You should also notice that the Krasi50 gearbox has a couple of STL files that appear to make no sense for a gearbox. They are his method of mounting coil springs instead of the leafs that Dean used.  Look for DaempferOben.jpg and DaempferUnten.jpg in the images section.

Good luck,

Show and Tell / My T35 - a few details on 3D printed parts
« on: December 16, 2020, 07:24:07 PM »
Hello, I just finished printing a few small parts and I know how interested some of you are who haven't yet committed to a 3D printer.
I'm attaching a couple of photos I took of a Hatch for the T35 as well as some little hinges for another hatch.  I've photographed them beside a metric ruler so you can get an idea of how small these are.

For a NON-SLA printer I'm pretty pleased with how these turned out on my Creality Ender 5.  I didn't even make special effort to accomplish this. I printed using a 0.20mm layer height ( I could have gone to 0.12, possibly 0.07 if I'd tried) so I'm pretty happy.

You might not be able to tell from these photos, but the hinge pin holes are clear and usable on all of the hinges.
I'll post some more shots of other detailed pieces in the future.
