Ron Gray Posted May 17, 2022 Share Posted May 17, 2022 Having designed and printed the exhaust shrouds and stub stacks It was time to move back on the airframe so next up were the gun ports I'm hoping that the inner ones (the larger opening) will produce the distinctive whistle produced by the full size ones! 3 Quote Link to comment Share on other sites More sharing options...
Jon H Posted May 17, 2022 Share Posted May 17, 2022 I am very jealous of your gun ports. I might need to make a cheeky request for my ugly mustang ? Quote Link to comment Share on other sites More sharing options...

GrumpyGnome Posted May 18, 2022 Share Posted May 18, 2022 Every time I see something useful, I think "must fix my printer". I've had it three years and successfully printed: 2 benchies 2 pilots; A thing to blow air onto the nozzle; A button to help release filament; A filament guide. Also probably used a full roll of filament on failed prints! Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted May 18, 2022 Author Share Posted May 18, 2022 That made me look at my ‘stats’ for my printer which I bought mid 2020 Used circa 2200m of filament Circa 190 days of printer time! Number of objects printed, haven’t a clue Quote Link to comment Share on other sites More sharing options...
GrumpyGnome Posted May 18, 2022 Share Posted May 18, 2022 Wowser! Those are (to me) big numbers! Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted May 18, 2022 Author Share Posted May 18, 2022 I do tend to get a bit carried away with printing things, I like the challenge of designing and printing bits! Quote Link to comment Share on other sites More sharing options...
Jon H Posted May 18, 2022 Share Posted May 18, 2022 Would it be possible to print a spinner? Its so hard to get spinners in the right profile and at a sensible sort of price. Even if the final print needed a layer of glass cloth, or was only useful as a mould to then make a glass/carbon spinner it would still be very valuable i am sure. Clearly, exploding spinners are bad but it must be possible to do something with it. Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted May 18, 2022 Author Share Posted May 18, 2022 (edited) I have designed and used 3D printed spinners but only for smaller models, I wouldn't like to try one greater than 30mm diameter! But one could certainly be used as a mould for a glass / carbon final product. Despite what I said above, I did print one for my Extra Wot powered by a G160 leccy motor. That did not explode but I was always wary of it so swapped it for a plastic one. Edited May 18, 2022 by Ron Gray 1 Quote Link to comment Share on other sites More sharing options...
Ron Gray Posted May 18, 2022 Author Share Posted May 18, 2022 Ports in place and blended in with some Ron's Sauce (as opposed to Freddy's sauce!!). I couldn't resist blowing them in with the air brush just to see what they look like, I will be rubbing them down a bit more before final painting. 1 Quote Link to comment Share on other sites More sharing options...
Jon H Posted May 18, 2022 Share Posted May 18, 2022 Yea i was thinking about the 4-6 inch sort of size spinner for 70-90 inch WWII fighters. I have a carbon spinner on my sea fury and it looked decidedly home made. I also have a spun ali spinner for my Spitfire XIV but as yellow no longer produce them its going to be impossible to get another should it ever be damaged. It seems silly to scrap a whole model because i cant get a spinner so it is something i have been musing over for some time. Quote Link to comment Share on other sites More sharing options...
Graeme White Posted May 18, 2022 Share Posted May 18, 2022 I am sure I have read a thread about a 3d printed prop so surely a spinner would be less stress? Quote Link to comment Share on other sites More sharing options...
