Is this cylinder for the DJS15 engine? It looks beautifully machined. Fantastic finish. I have a couple of Rossi Mk2s with steel liners that I'd like to lap and make new pistons for. I'll do it the same way as you have here.

That's a familiar sound! I'm learning F2A too, and my flights so far have been similar. That balance of needle setting and tank position is very challenging. Perhaps a more inboard tank position will give more fuel pressure to work with in flight...

Hi Olli, I'am just wondering if i can get a 3D printing files of this moulds..

Very nice . Congrats

Nice work Olli, but although I like to keep my hands clean I would never under any circumstances wear a glove of any kind to hold a rotating item in a lathe. There have been many cases where the glove has been picked-up by the rotating item and the consequences have been dire, any where from simply skin being ripped of the hand to... well, just think about it. PLEASE DON'T DO IT.

Another excellent job from you Olli...but why don't you posting this to our Emco group...?

never, ever, use diamond paste in your machine shop, because, as they say, a diamond is forever, it will not break down, it will wear down your tools. This produces a mirror finish which isn't necessary for model engines, especially those with rings, it hampers oil retention.

What grade steel ?

How did you check for roundness with a bore comparator? Bores can be bi lobed, tri lobed etc. which bi lobe or tri lobe measuring instruments will not detect if the bore has a constant dia., but is lobed.

Superb Job !

That ran really well. Interesting carb position.

I forgot to like it when it came out, but I made amends now. Such a great project to see, from Viipuri of the "golden age", a decade full of hope and progress in Finnish history (until it soured)

Bro please make vedios of installation i want to make candle base stirling engine fan to big hall color speedity fan please

It can fly?

The prop speeds up hence the mixture leans out, that's why

Madness indeed! Flying over water is just crazy. I wouldn't do that to my models or engines. Just fit a tiny r/c and stay safe.

Perhaps a slightly smaller ventury ?

Made one with a dc bantam !

Hello! When you throw a plane, the fuel rushes back and air gets into the engine. You need to make a good tank with a dividing wall inside. In this case, the fuel will not foam and the engine will not suck in air bubbles.

ACtualy you have made a very good runner! it seems to start very easy ! realy nice model too ! i hope you can sort out your fuel issue and want to see i a good flight soon

No way !!!

Excellent installation very well done.

Подари мне😢

Well done Bljed !

"Know what I like about this engine? It was built solid; And? That is what is needed. No plastic fittings for fluid fuel corrosion due to tolerance of material. However? I would like you to install a spring crank around the shaft area near the spinner for easy start. Overall? The item is good." 👍

Respect.

I've just realised how much I need a miniature ICE bolted to my coffee table,

It's listed as a 4 stroke; does it have an oil system or is oil mixed with the gas for lubrication?

Nicely done, ignore the peanuts!

Wondelfull work!!!

very good work !!!!

Tienes un hilo en el foro

no core insert..?

Bravo ! Formidable ! Excellent travail de Technicien supérieur !

Beautiful old engine design...I can't decide if Im more impressed by the engine or the facility's you used to make it with...🤔😳😏🇬🇧

All this hardwork, and you used brass bushing...well atleast you did'nt use needle bearings.

I think you should use breaker points with a 1988 Ford Thick Film Ignition module of the minivan-remote-from-distributor-on-a-heatsink kind. When used with it's matching coil it can supply a V8 with sparks to 5000rpm. Best of all is somehow it calculates the proper "on" time for it's coil before every spark. It also shuts off after one second of no rotation. Marvelous piece of old tech nearly as hot as GM HEI which everyone know is a PITA but has a strong spark.

Poezja. Cudowny gang.

Unbelievable! Hats off to such masters! Great job! +

Great job !!

Very tidy work! Did you connect the milling head to the same vfd?

Great job. Can you add the used components and wiring diagram? Is this a single- or three phase motor? Is it US? We have 230 Volt SP or 380 TP. Thanks for sharing.

Very nice well done, this is going to be my next project, and thank you for the plan and the video👍👍👍👍👍👍👍👍👍

Nice work.

Beautiful. Thank you for sharing.

Hi what size multifix holder are you using on the Emco 8

How about hearing it sing after broken in? I fly experimentals and sputtering is a nightmare, hahhahah. Thanks, Thailand Paul VW Power.

I wonder how you did the precise matchig layouts for the tool and the holes in the cover for it. I also have never cut thread with a lathe. I guess the feed is automatic. Thanks, Thailand Paul
