..one opportunity at the time..
That’s the way we used to (and still mostly do) design our stuff. If it looks right, it will fly right. Works since the days of the Wright brothers (and all those that went before and came after them.) However, fun has to be had! I need to sort of start thinking about the wings … Read more
Should make a note of where I got stuff, because I keep forgetting 😉 Those nice 2 mm flatheaded bolts: https://www.aliexpress.com/item/4000053423419.html should get you close..
Making the top wing center-section is a bit of a challenge. The drawings are not very clear. I started by making some fake parts, and see what makes sense. There is also no need for the wing-tank, which saves a bit of hardware. Given that the original construction was usually very clever, it pays to … Read more
Had some issues with the 3D-printer. Sometimes it would tell me the bed was not heating at the required rate and shutdown unceremoniously. Not Good. After the usual suspects were proven to be innocent it was the ntc resistor under the bed. Tiny as it is, it is a vital bit. Why oh why it … Read more
I was still not happy with my ABS printing efforts, and determined the only way forward is to chop up the large pieces. Mind you, that 9 cylinder engine is definitely a printer killer. If you can print that, you can print anything! So, chop chop. Yep, there is an app for that. Anyways, results … Read more
Since the winter appear to be absent in my shed, it is not too cold to make some good progress. Progress the last few days has been getting to grips with Shapr3d. I Mentioned before it is one of these bits of software that will change the way casual users are going to be designing … Read more
Daniel (#2 son), is doing some free-lance development work for game-figures. Once you have the design it is a small matter to see if your figure can be printed in Real Life. Since the printer is loaded up with ABS plastic, just press ”go”. I printed this one flat, with 0.2 mm layers, and not … Read more
With the skins ready it is time to do another trial fit. And this is where I discovered a booboo.. The bolt that locks the elevator pushrod in place interferes with the skins. Ok, don’t panic. Think. The 3mm bolt is not really 3 mm, it’s 2.9 mm. That introduces unwanted play, so it is … Read more
With all the good times behind us, it’s time to start work again. Santa was kind enough to bring me a handful of drills in all sizes from 1-2 mm. So it’s time to start drilling and tapping holes again. Officially I should drill a 1.6 mm hole for a 2 mm tap, but I … Read more
This time of year other things need my attention, so I’m a bit slow at the moment. I’m still working on the tail side plating near the stabilizer of the SA750. However, something as mundane as ‘a bit of plain 2mm iron strip’ proves hard to come by at the moment. Everywhere I look I … Read more
