As more of an engineer than an "aeronautist" I decided to make a twin cylinder double acting air engine of my earlier single. It makes a very compact layout and would of course be be self starting.


A video showing the internals moving.

It running on a vacuum cleaner.

Interesting more than practical.

It will never fly, but this is what has been keeping my from my spit!

I built a home brew mendelmax alike printer, great fun but I kept looking up at my 3 part built planes hanging above me in the workshop.

my new friend kept me busy, I wanted to up production so designed my own printer that I could print, then printed that, so now have two printers.bf1ce6b2-3719-49e2-b84e-a945a834b3d7.jpeg

whilst looking at servos for my 3D printed robot, I remembered my Spitfire - Now my printers will be printing Spitfire cannons and arials and air scoops - the fun never ends!!

My 1st home brew 3D printer - works a treat !54350081-39f8-40c5-88ca-a6eb5c24cbc7.jpeg

My own designed (inspired by others out there), printable from any 200x200 printer, I bought all of the non printed parts from Amazon! And B&Q 😁

I have tweaked it since this photo to give it a little more rigidity and height so that I could add a wades extruder. This was the 1st prototype.

Infectious pastime is it not! I am curious as to why you used printed A frame components instead of M8 threaded bar that you used for the cross members, I would have thought the bar would be stiffer than the plastic. I know there are designs out there for the plastics of the Mendel printer, because I built one, and if self design was the main motivator then couldn't adaptation of the existing parts, or creation of new designs have satisfied that inventive urge?

Here's mine..used yesterday to make a new lever for my Saitek throttle quadrant that I accidentally snapped off with my chair.....again!

A 3dlabprint Spitire. Flew great until I tried launching it from a dolly rather than chucking it. The result was a lot of broken pieces. Must make another...

To be honest I didn’t start out with printing it in mind, I was going to use 20x20 T slot frame again, but everywhere I looked the frame would have cost a fortune.

it looked like buying a Prusa or some such would be cheaper than building it myself, and that goes against the grain.

As usual I looked around my workshop, I didn’t have enough threaded rod to hand (yes I could have bought some!), but I recently bought some reels of filament..........

there you go, would have been far less bother to use threaded rod, but I had started down the printed frame road🤡

now it’s done and up and running I am quite pleased with it, though I haven’t used it for a few weeks now since I got the RC bug again.

Furlough has had its advantages - all 3 printers here have been flat out for me and customers.

1/4 scale seats and switch panels for a CT-114


Lots of ordnance for my Vietnam veteran :


FRSky rx and aerial mounts :


A whole bunch of 10th scale Spitfire parts - exhaust stubs, control columns, radios, gun sights, throttle quadrants, rear view mirrors.

I needed to test a small (9.5 g) out runner (5x3 prop) and could not find my home made wooden test stand but in any case the motor is so small none of the pre drilled holes would have been usable.

So I designed & printed one. smile o


Basically hollow boxes with 8% infill. The most complex bit was creating the top plate to match the motor mounting holes. It includes 3 small holes that allows the screws to 'self tap' into the plastic.

It used 2.75 m of filament and took 48 minutes to print.

Not very sophisticated but with the current 'lock down' it seemed a reasonable (and cheap) way to pass the time.wink 2

On a 3s it confirmed the motor/prop combination would produce a more than adequate thrust for the intended application.

I am in awe of all that I see here, from use of someone else's plans/files to self generated files and expanded priter capabilites to a complete printer built from bits. Absolutely amazing!

I have designed and printed some servo covers / holders in a couple of sizes. They were designed in TinkerCAD which I find is quite reasonable for designing basic components like these. I did show these on the TN 78" Vulcan build thread, but here they are again for those that have not seen that thread. Rudder and elevon servos.

just an update on my build.. 3 cylinder aero engine for my curtiss CW1 1/6th scale...

engine 012.jpgengine 010.jpgengine 004.jpgstill a bit to do on it but begining to look ok I think..

That looks really good, will make a nice addition to the Curtis model.

My latest 3D print, engine related but very simple in comparison, exhaust support ring and it survives the heat !!

My most complex print so far. A 'spare' ASh-62 and bulkhead mount for my AN 2.Xash-62

It follows my usual 'lots of bits glued together' approach in fact there are 73 individual pieces just to make up the 9 cylinder radial. It is also self coloured, the parts being printed in silver or black filament as appropriate.

Intended to replace the slightly simpler version current installed in the AN 2 if and when it got damaged but so far that hasn't happened.

What filament did you use for the exhaust ring Barrie?
