  1. Need a Gatorade bottle for that in a dynamic environment. Awesome work, Pete. Keep it up!
  2. As always, it’s best to confirm assumptions *before* tweaking a design. The ADF uses the M2 Quick Change Barrel .50 calibre machine gun, not to be confused with the US M2A1 Quick Change Barrel. The former has the barrel alignment keyway recessed on the barrel, the latter with the keyway cut into the perforated barrel support. Initially it was thought that the weight of the 50 cal & associated ammunition would be too heavy for the PMV. Turns out it wasn’t. The 50 cal is fed direct from the open topped ammunition box, with the lid attached to the side of the box
  3. Thank you, gentlemen - I appreciate the feedback. The time spent on drawing up the cradle was worth it - for a MAG58! Unfortunately, there’s no commonality between the the cradle for light/medium machine guns & the 50 calibre. As can be seen above, the cradle for the .50 is pretty beefy! Hopefully I’ll have time to finish it this week.
  4. Luckily printing is set & forget! Here’s the first iteration of the PWS.
  5. A return to work = a decline in model productivity. Most of the designs are largely complete, or at least blocked out, requiring final adjustments & details. The Platt swing mount currently looks like this: The EOS R-400 remote/protected weapon station was next. The PWS will be fitted with a .50 cal M2 with Quick Change Barrel.
  6. You’re right, Mark. It’s one of the most popular 7.62 NATO machine guns. Heavy to carry, very effective when employed correctly. Re. the CTIS, the air hose is a metal segmented hose to resist terrain & vegetation-induced damage, but it is unarmoured, as you say. Maybe it figured that it’s just a small target? Need to adjust the MAG58 I bought from Shapeways & add the trays for the ammunition boxes on the left side of the cradle.
  7. Which didn’t take long. Still need to model the cradles & ammunition holders, the the swing arms themselves are more or less done. These will have MAG58/M240/GPMGs mounted. Mirrored & printed the wire cutter for the RHS.
  8. Mucking about with minor parts today. Firstly, the wire cutters were CAD’d up. These are located in the upper corners of the windscreen. I’ve modelled them in the folded position. Without the ECM antenna. Then it was time for the front (small) & rear (large) crew steps. On to the machine gun Platt swing mounts.
  9. Mocked up the base today, using a 12mm sheet of MDF cut to 500 x 200mm/~20” x 8”. Countersunk holes for the M6 bolts were drilled, then the model test fitted. From the front. When mounting properly, the M6 nut will be run up the bolt and tightened again the M6 nut that’s been epoxied into the differentials themselves, creating a mechanical lock. That way, the weight of the model is borne by a pair of bolts, rather than scale. 3D-printed suspension units. From the rear: Overall. Once fine tuned, the suspen
  10. Thanks Mark, I appreciate your continued support. Apologies for the wall of text, but here’s a bit of background to the wheels. My original plan (2019) for the model was to use the complete suspension from an off-the-shelf M-ATV kit, with the remainder being scratch built. Thanks (?) to lockdowns various, I embarked on the journey to learn CAD in March 2020. As I learned more about how to use CAD, the number of parts intended to be borrowed from the M-ATV kit shrank. The M-ATV tyres are correct for the Bushmaster, so remain part of the build. The hubs, how
  11. Sorted the fit of the transmissions, suspension, & the new build blocks that incorporate M6x40mm bolts as the mechanical interface. Up the right way for some context pics. Only the front & spare wheels are correct for the Bushy. T’other side: Ride height looks good, overall look is what I was hoping for when I started out.
  12. Happy 2021, all! More or less finished the suspension & transmission design & print. These parts have now been assembled, test fit, then glued. Took the opportunity to test fit the fuel tank & winch. Also verified the ride height with the wheel assemblies - all looking solid, so far. Happy that it’s all coming together. Almost paint o’clock.
  13. At the risk of spamming....here’s the differential/suspension design as of now. Not sure I’ll finish the design this year with only 14 hours to go! Dry fit on the dummy hull: On the hull itself.
  14. Upper arms have all been printed, as have the axles. Only four more parts to design, fourteen to print in total. That’ll finish off the suspension. Considering how much will be obscured by the hull & wheels, I’m satisfied with the level of detail. Some more cleanup, then time for the FS30219 tan.
