dodgem37 Posted December 19, 2020 Share Posted December 19, 2020 I was thinking along the lines of explosive doors, much like armor. Thank you. Sincerely, Mark GMK 1 Link to comment Share on other sites More sharing options...
GMK Posted December 20, 2020 Author Share Posted December 20, 2020 Another lesson for the week was “never trust someone else’s CAD”. Here’s the result of a 1:1 model, inclusive of scale wall thickness (!), printed in 1:16: These are my design & prints: And on the truck: Took the opportunity to mock up the placement of the 84mm ammunition on the side using double-sided tape (Tamiya scale figure for reference). Overall shot: With stowage largely complete and holidays commencing, I can return to components that are more tricky to design. patricksparks, Uncarina, chukw and 5 others 8 Link to comment Share on other sites More sharing options...

GMK Posted December 23, 2020 Author Share Posted December 23, 2020 Well, with the week before Christmas & a mini lockdown in place, there’s finally been time for finishing outstanding designs. One of the biggest chunks of design to complete is the fuel cell & winch. These are located on the left side of the hull. That’ll cap off the most visible elements of the stowage. Finished off the A-frame design. Now on to the suspension! patricksparks, Rockie Yarwood, chukw and 1 other 4 Link to comment Share on other sites More sharing options...
GMK Posted December 24, 2020 Author Share Posted December 24, 2020 (edited) Merry Christmas, all! One positive (?) side effect of the recent lockdown is that my Christmas Day is remarkably unencumbered. Time for some CAD. Here’s the transmission housing. This is common to the front & rear axles, just rotated 180 degrees, horizontally. The two parallel protuberances on the top of the tx housing will interface with matching recesses on the PMV hull. As these will be supporting the majority of the model’s weight, they’re printed with 50% infill, as opposed to the normal 15-25%. The underside of the housing has a recess for a M6 nut. This will be the mechanical interface for a M6 bolt that will be inserted through a yet-to-be designed base to take the weight of the completed model. So, with that sorted out, the complicated bit of the arms, axles, and the like now becomes a priority.

dodgem37 Posted December 25, 2020 Share Posted December 25, 2020 'This will be the mechanical interface for a M6 bolt that will be inserted through a yet-to-be designed base to take the weight of the completed model.' I like that. Good show. Sincerely, Mark Rockie Yarwood and GMK 1 1 Link to comment Share on other sites More sharing options...
GMK Posted December 28, 2020 Author Share Posted December 28, 2020 Printed the two differentials out, adding the M6 nut and some detail stolen from the 1/16 M-ATV. The M6 bolt had been screwed into the nut to keep paint out of the threads. The 1:1 truck has a 400mm ground clearance, equating to 25mm in 1:16. Here’s the first iteration of the lower suspension arms. Once some of the interface areas have been re-finished, I’ll get them printing. Upper arms are next. dodgem37, patricksparks, Anthony in NZ and 3 others 6 Link to comment Share on other sites More sharing options...
dodgem37 Posted December 28, 2020 Share Posted December 28, 2020 Nice work. Are the arms pinned? They appear as if they could be. Pinned arms may present a problem figuring out the shock absorber 'spring', tho, in order to gain a flat sit.

The arms will be pinned...thankfully I’ve sorted the shocks! The length is fixed, but the shock assembly can rotate around the pins. Upper arms being printed inside the next 24 hours. Apart from layout, the suspension arms are “representative only”. They’ll largely be hidden behind the wheels themselves. chukw, dodgem37, Uncarina and 2 others 5 Link to comment Share on other sites More sharing options...
GMK Posted December 30, 2020 Author Share Posted December 30, 2020 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. chukw, Anthony in NZ, panzerrob and 2 others 5 Link to comment Share on other sites More sharing options...
GMK Posted December 30, 2020 Author Share Posted December 30, 2020 (edited) 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.

GMK Posted January 1, 2021 Author Share Posted January 1, 2021 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. patricksparks and dodgem37 2 Link to comment Share on other sites More sharing options...
GMK Posted January 3, 2021 Author Share Posted January 3, 2021 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. patricksparks and dodgem37 2 Link to comment Share on other sites More sharing options...
