PART TWO HERE th-cam.com/video/7p8_MKLJ8l8/w-d-xo.html Best wishes for your bloody gorgeous holiday season and a great New Year:) Support me with a "like" on the videos, drop a comment, tell a friend about the channel. Let's grow it through 2025
I love cats...and model engines! Cheers from David in South Carolina, USA!
It's a perfect match. Welcome David!
Great little engines .
Gorgeous stuff mate so thanks for sharing, I'm a first timer so looking forward to seeing your new year's work
Great to hear from you, you're most welcome. Who knows what 2025 will bring?
Things of the past become passions of the future
That's deep and seems to be a tru-ism. But why?
Hi Thomas, lovely recap of your beautiful engines, hope you have another great year with some more fab engines to show us! I have a new M17 but seems like the hall sensor is faulty, and a lovely Musa Hoglet V twin to get up and running soon - Best Regards and Happy New year to you. Ade
Thanks Ade, it's appreciated :) Same to you
I have been curious about the MUSA hoglet as I bet it is MUSA's superb engineering. Do you feel that?
@@ThomasPCGuruENGINES I do indeed, I ran the hoglet last night, started straight out the box and its a ripper! The Retrol engines seem to always need a bit of work to get them to run as you want them to.
@@AdeSwash Thanks Ade. MUSA engines for the win
Hi there you are one sick puppy I thought I was sick but WOW the attention to detail is out the gate not much rips my shorts but the likes of the wood sleepers on the flatbed loader that look exactly like they would on the real deal.. if your a bloke and you watch your videos and don’t get a twitch going on your not a true bloke !! Love your work!!!
Bwaaaahahaha love it. Thanks for the comment! But really, I just play
It was light weight, efficienr, easy to build,and quite able to fly free flight models swing a 12 inh or larger prop. Much easier to build and maintain than those clunky sinker weight motors which you display.. Light weight and efficiency is the byword with free flight.
Yes, the early free flight engines were such a joy! The more modern engines are more for looks than performance. I well remember running across fields in rural Canterbury, New Zealand and launching my Vic Smeed Tomboy into the blue. Sometimes it would catch a thermal and nearly disappear. Happy days...
OKMO / Microcosm news - Jin has a bunch of exciting new model engineered engines including hit and miss, stationary, tractor, and a vintage generator model. Subscribe for updates on these!
bought a retrol hm-01 and it arrived for christmas (i didnt buy the base since it wasnt in my budget, and i could make one myself). Call me an idiot because i spent hours trying to get it to have compression but then i realised the spark plug was still in the box.
Bwaaaaaaaaaa hahahah you made my evening. My dude, we have all been there
....Also, for this quality engine, give credit to the perfectionist, passionate engineer at MUSA. "Retrol" is just a retail brand partnership of convenience :) You have an heirloom model right there
Bonjour Thomas,
As great collector and skill mechanic, how many of your engines start out of the box without any enhancement ?
Which one would be your preference ?
And when comes the vertical Retrol Hit & Miss engine ?
Bonnes fêtes,
Amicalement, Raphaël
Nice to hear from you Raphaël. For me, the pleasure is getting the engine running what I can achieve "perfect" and learn a bit. Early engines like the M90 needed valve lapping, new main bearings, retiming the exhaust valve. Lately, engines like the Microcosm OKMO v twins need nothing done. Having to lap valves seems to be a thing of the past. I still find that a batch of engines built by an engineer's employees rather than the engineer himself will not be assembled so well. OKMO's tiniest Stirling engines are perfect out of the box. But their Rider Ericsson's usually need fiddly pump work and are simply too small. Hit & misses can always use cam and detent latch optimisation. Kontax low temperature engines are perfection, but their high temperature mini engines have machining tolerance issues with the pistons-cylinder fit, which I guess is acceptable. I don't know when the Retrol MUSA vertical will arrive, surely soon???
Hi Thomas, have you any videos on timing a Eachine hit and miss engine, I know about TDC and the spark, no one on youtube explains the position of the cam at TDC though. many thanks for all your excellent videos over the year.
OK let me try to think it through. Not at TDC, but the exhaust cam should open at the beginning of the exhaust stroke and close et the end of it.
Many thanks Thomas, I will try that. wishing you a great new year, keep up the good work.
@@bertyjustice For my hit and miss, ignition just after TDC gives a great single "hit" firing at low speed. The following stroke forward is the power stroke. That stroke ends with the piston as far away from the cylinder as it gets, then as the flywheel carries it around it is the exhaust stroke., The exhaust valve opens at the beginning of this stroke. The flywheel rotating keeps it pushing smoke out the exhaust, until the piston is almost back at TDC and you close the exhaust valve. In a hit and miss, as the flywheel carries it through the next stroke away from the cylinder, the governor either holds the exhaust open (miss) or if it allows the exhaust to close, the suction formed opens the intake valve and petrol-fuel mix is sucked in preparing for the next firing (hit)
Thanks again Thomas, I have printed the information out to study. Have a great new year
Thomas have you used any lube/graphite on your R01 piston? Cheers Jim
I haven't...I have had some good suggestions tho...was it you?
Have you run a "Hoosier Whirlwind" compressed air model aircraft engine? Designed by Bert Pond in 1928 and quite popular.
I will look it up, sounds interesting
that m19 engine looks like it had a lot of mods done on it
Mainly I like to add a switch so that it only fires during the hit part of the hit & miss cycle so it's not wasting battery and it's quiet
@@ThomasPCGuruENGINES ah
that explains it
12:41; Leider ohne Kreutzkopfführung.😏😏😏😏 Viele Grüsse aus Warthausen bei Biberach an der Riss.
Yes a cross head would have been extra nice, at this price range it is as unusual as the condensate drain cocks. Many greeting back to you, danke!
That's not the way to drive a recipricating steam engine. The cut off is not a regulator.
? As there's no other way to do it on this engine, I'm curious to know what you mean
