Looking great Alwyn. Could you possibly sneak a micro servo under the gun like the 88mm you printed for the Nashorn and make it recoil? Either way it's fantastic

After some brutal work on the sherman chassis to remove the battery box and associated fixtures and fittings I started to look at how the turret would be mounted. I had a goldilocks dilemma, the standard HL turret ring was too small, the large HL turret ring was too large at 140mm diameter, so I had to devise my own which is just right (that's the one on the left, the one on the right is the standard.
Image
Having developed and printed the gear ring, the next move was to modify the turret design and it now looks much better, plus I could make a start on the upper hull. The turret floor opening is almost correct to the blueprint but I can't enlarge it any more due to the constraints of the turret gear ring.
Image
The turret base opening is almost correct to the blueprint and the new design turret ring is still compatible with the HL turret turn motor.
Image
Image
The upper hull is still in skeleton form for prototyping as I don't want to waste time and filament printing something that may not work. Once I've printed and proved it I can then fill it out.

Your new turret ring looks excellent, can I ask what your doing the design in is that Fusion 360?

I have only really tinkered in tinkercad, but as I look making parts for Tank's it seems I have many hours of learning ahead to try and get some basic skills in 360.

Hi, I use OPENSCAD and have used it for about 5 years now, I find a flexible and powerfull CAD tool and is fairly easy to learn, after all I learned it and I never had any previous experience with CAD. The link is here
https://openscad.org/
The software is free, well supported, and there are many teaching videos plus an excellent on-line help manual available. I can thoroughly recommend it. The turret gear was a design done using a gear model available on Thingiverse
https://www.thingiverse.com/thing:4194148

In fact there are a number of scad designs on thingiverse

Thanks for the interest

Thanks for taking time to reply, I am going to investigate openscad then, and the thingiverse model for gears.

I have been watching YouTube tutorials in an attempt to understand rack and pinion for recoil in fusion360 - pretty complicated stuff!

The Achilles is going to look great :thumbup:

The first section of the upperhull is printed

Oh I do love it when a plan comes together :haha: :haha: :D
I'm thinking that rather than filling in the skeleton I will rather skin it, It will make it faster to print and because the skins will be printed flat there will be no desposition lines plus detail can be added without being distorted.

Hi Alwyn!

Fantastic work, I will stay here to see your progress :clap: :clap:

I like the idea to use a skeleton form for prototyping, thanks for share with us :thumbup:

The front part of the upper hull is now printed and I can see some minor tweaks that I need to do, but generally it's looking good and fitting perfectly.

I'm really pleased with the turret open space as the turret gear ring fits perfectly

Looking good so far
