Philtech V12 Engine Test Run
Просмотров 4,5 тыс.2 года назад
This video demonstrates starting and running of the Philtech V12 engine. It is a 108cc 2 stroke 12 cylinder model engine. It is suitable for 1/5 scale model aircraft like the P51 mustang. It runs on Methanol/Nitro methane model engine fuel. This is the pre production prototype. Available early 2023. Contact info@philtech.com.au
Claming around an object it would be weak because it relies on the springy contraction of the 4 jaws. That is a big drawback. The other big drawback is lack of rotational adjustment. When you screw on the jaws part to the chuck you are limited by where it rotationally stops, and that is also lacking precision because the angle will be affected by how tight you screw it on.
Regarding the comment about relying on the springy contraction, it has the advantage of having contact with most of the diamater of the part it is holding. The main reason for using this product for when you have a difficult item to hold ie. a thin walled tubular part or a non round item that requires a custom machined cavity. You may need to adjust your depth of cut to allow for the gripping pressure.
Nice product Phil, I like the selection of adaptors, I’d be able to adapt this to my little hobby lathe very easily.
For holding on the outside of parts does it rely entirely on the natural flex of the arbor and can't be tightened any further by the key.
Yeah I saw that problem too. I suppose if it was critical, you could make an outer clamping ring similar to the base clamp ring.
@@wizrom3046 I suppose so, but the clamping ring datum will be referenced on the 4 Aluminum moving " jaws" that do not open or close parallel to the centre axis. They individually swing hinged on their bases at the bottom of the slits. I would expect the questions in the comments to have been addressed by now.
Yes you are correct that when holding on the outside of the parts the flexi chuck relies entirely on the flex of the arbour. It is worth noting that unlike a 3 jaw chuck the flexi chuck has contact with most of the diameter of the part. Also we produce the adaptor in machining grade aluminium (2011) and also high tensile grade (7075) for when more grabing pressure is required.
Do the quadrants flare out at the ends as it is tightened?
While it is correct that they adaptor pivots from its rear, if the flexi chuck adaptor is machined as close as possible to the diameter of the bore of the item it is holding ,then the ends should stay parallel and not flare out.
@@PhiltechEnterprises Thanks for the reply. To hold on the range of different bore sizes produced during a production run the adaptor will have to be machined to just under the bottom limit. Therefore all but the bottom limit parts will only be gripped at the end of the adaptor and theoretically only on the middle point of each segment end. This feature is overcome on 5C and R8 type collets by making them with much longer more flexible leaves that allow the location area to flex into the parts bore.
In Australia, we call them dye craft chucks. They were popular back in the 60's - 90's. Sadly, they are no longer manufactured here, but I still have some blanks for mine.
We are based in Australia and decided to build the flexi-chuck because the Dyecraft chucks were no longer available. But we decided to make some arbours to allow it to be more easliy fitted to machines.
Well done Phil, a very useful addition to the machine shop - regards markc
Being a machinist, HOLLY COW. People don't realize this is a better part of a 1000 hours of work. Much respect!
Can't wait to get 1 of them engines in 1/4th scale
I didn't realise it was a 2 stroke, and water cooled. There must be a few design challenges right there. I have a Flexi Chuck. Saw the brochure in the background. Cheers, Preso
I checked your website. Didn't realise that it's running glow fuel not petrol. This gives us two problems. Fuel load and availability of nitro fuels. Any thoughts on this?
Mix your own fuel. You can run less oil in the fuel than regular glow fuel because it only revs to 6000rpm and is water cooled. Maybe 10% oil max and no need for nitro. Methanol is freely available so is synthetic oil. A petrol version of this engine would be double the price to buy
@@weofnjieofing The sales spec says 10 - 20% nitro. A petrol version doesnt have to be twice the price. It's fourstroke technology that would increase the price. Electronic ignition isn't a big deal. There is an engineering reason. Most likely space is to tight for a spark plug.
What is the expected price of one of these?
It says on his website
$20,000 aud

Looking 👍🏻
I've only just found your channel. Thank you for your hard work and quality content.
Stunning stuff!
Is that a real super charger on the front of that?
That is OUTSTANDING a real v12 that’s friggin bad ass as it gets
Please supercharge it
Absolutely amazing! How can I get that engine for my 1/5th scale Mustang Sally?
Stunning achievement to get this far! Beautiful!
Very informative Phil- regards markc
Your voice is very calming :D
good stuff!
wtf ghahah way too cool
Magnifique , comment as tu conçu l'ensemble distribution , elle n'est pas côté hélice apparemment ? Encore bravo V12...si petit , en l'air il va avoir le timbre de Voix du Merlin ...En moins grave !
Im looking forward to your process. I started building a v8 about 20 years ago and after some problems with my cam designs it hit the back burner and i never went back to it.
Wow! A truly remarkable piece! Thank you for allowing us to watch and congratulations!
this is incredible craftsmanship, well done.
Too much Yap yap yappin' and not enough motor!
Screaming it’s head off, sounds awful so gotta wonder why bother?
That sounds crap
Awesome work! But the sound of that V12 is disappointing. I guess the displacement is too small. A Moki 5 cylinder radial sounds much better.
Maybe try designing a gas powered 4 stroke V12 in the future. I know the logistics in that endeavor are immense but it would be amazing. Beautiful engineering on your V12!
That is very nice and smooth. Thanks for sharing. Many happy flights😅
Nice bird. I like the sound of that engine and looks awesome
It's a fantastic plane, has potential to be great.
Wing loading looks too high....Should work with more wing area and more pitch....😳🤔🇬🇧
E-Gad 😳! This is unbelievable! 👍👍
Spectacular! A 1/5 scale V12... liquid cooled 😳 👍👍
Beautiful sounds.
Wow!! Very nice 👍
I know the feeling having just done the first test flight of a 1/4 scale FW190 ,,well done to your team
Use a higher pitch prop and a wider blade. Or, use a gear ratio of 1: 1.2 since you are using a v12 engine.😄
That is cooler than cool.
Да, английские инженеры, уделывают до сих пор всех остальных.
Looks and sounds awesome.
Absolutely beautiful machine!👌
Wow! 👌 After nitriding inner surface pass honing process also ? If to make liner from high quality cast iron is it very big difference from steel liner ?
Very interesting 👍
