Casting and Machining a Retro V-Twin

- In this weeks video we check out my V4 350cc 2 stroke patterns before looking at the progress on the retro V-Twin engine. I cover the lost foam casting and then the machining required to take the castings to an almost finished state.
All of the CNC milling is done on my converted Optimum MH-28V mill running on Mach 3, all the CAD and CAM is done using Fusion 360.
Make sure to like the video and leave a comment.
Thanks for watching.
I learnt something today! I have never seen casting in dry sand like that before.
Some of the coolest milling and casting work on TH-cam. Can't wait to see that engine run.
Thanks. That makes at least two of us.
Take that goofy swivel base off that mill vise & bolt it straight to the mill table- you'll gain height and lose floppyness and have a more rigid setup
Go easy, he is a novice..
Shot bro! Sick video, love seeing how you do things. Keep it up
this is so rad, I'm hooked. Keep em coming
Awesome job! You have some serious skills looking forward to seeing more
Thanks, hopefully the next video won’t be as far away.
Wondered where all the spoons from the smoko room went 😂
Watching from Finland and liking your approach mate
Thank you
Appreciate all the explaining of what's happening. It's looking good, all that experience from the first one seems to be coming into play
Thanks you, it does seem to get easier each time.
entertaining and informative looking forward to the next update
This is such an awesome channel, keep it up!
Excellent work, looking at the finish you got on the mating faces of the case half's i think your heat treating exercise was a success
I think so too, the threads also seem fairly strong in the tapped holes.
I cannot think of a better use of Tesla rims, or any other Tesla aluminium part come to think of it 😀. Nice work Jonny, keep up the greak work.
Haha, thanks.
@@OddsandEndsMachiningNo problem Jonny, I'm surprised Brad has'nt got you to cast up something for the Borg yet 😄
Should have plenty of the Cyber truck rear frames to melt down soon enough. First time anyone uses it as a real truck it's going to break and rip off lol.
Nice castings. I've never tried lost foam castings before. I like that you don't need to worry about draft angles.
Regards, Preso
Thanks, It definitely makes design considerations a bit easier as no cores are required.
Looks like you had nice temp control on your melt, so low porosity? Nice one.
Thanks, I haven’t come across anything major, in terms of porosity. So I think this one is a success.
@@OddsandEndsMachining What was the basis for your geometry? A J.A.P?
Really love this type of builds engine merging isnt a new thing and an easy thing but u make it seem so easy todo! hopefully you decide to make big displacement engines sometime in the future 500cc,600-1000cc
love watching all your videos!
Xr650 heads and barrals to go 1.3L now that would be something
Thanks, there are a 3 engines (including the V4) on my hit list before I make something big, but I do have a project in mind.
Love the progress 🙏🏼
After watching your lost casting and subsequent machining, I had an idea that I was wondering if you’ve tried:
Have you ever considered putting Heli-Coil threads into the foam casting along with white oak wooden dowels spun into their center as plugs but sticking out into the sand by around 4” to help secure their relative location as the supporting foam is lost?
You wouldn’t need to worry about getting it lined up with the top since you’ll just be machining that surface flat anyway and the wood dowels will undergone a quick carburizing with little oxygen so they won’t burn away but their exterior in contact will quickly turn to charcoal making removal and cleanup simple and quick.
I know nothing of lost foam casting and barely anything of traditional sand casting aluminum so I can understand if my thought fails at a fundamental level because of something like the high heat ruining temper of coils OR more technical challenges like the aluminum skin fails to bond with the exterior of the coil or the protruding coil may potentially disrupts the molten metals skin causing it to fold over and create defects which in turn could lead to voids or weakened sections at the location of the folding. Anyway just a passing thought, I enjoyed the video and was able to inference a few things based on how you made your fill channels.
1 of 1 casting or 1 of 2 casting "gonna test my first ever gcode" i was like no no no no no 🤣
My idea of living life on the edge
Very nice work sir
Strong work!!!
I wonder what kinda crazy stuff that you and Alan Millyard could come up with…..
Some of the most impressive non-industrial casting I've seen.
Not here for the nooks and crannies castings.. Well maybe
Here for the fush an chups bro!🇭🇲😂...
Big modified tractor pull at my place. Spring Ridge NSW..
Ohhhh were all pullin 👍
The V engine is bonus batter ..
WOW 😍
This just popped up in recommended, I watch far too many machining video's but making a V-twin- cool stuff
(I was a motorcycle mechanic at various dealers in 1970's~90's then taught at MMI Orlando almost 12 years).
Love the irony of making IC engine from Tesla parts.
What top ends are you going to use?
I see you have slots for cam chain, looks like Honda pattern (XR200's?)
Keeping the Kiwi tradition going, great stuff, I'll subscribe
Thanks. They are Chinese copies of an xr70/crf70 cylinder and head.
@@OddsandEndsMachining That's really cool.
In te 80's I wanted to do similar with XL185 top ends as I had a few.
Never got around to being anything morethan a dream though.
I still haven't done any casting either, always seems to be something more important (usually expensive) to fix instead (particularly since I got married) 🙄
Impressive
Good to hear a kiwi accent. What part of the country are you in?
The one and only Palmerston North
Casting looks good considering the porous looking sand. How did the heat treat work ? T-? . Nice work
Without any legitimate way of verifying the heat treatment I think it went quite well 😂. I went for a T5 heat treatment as it is 80% as good as T6 but a whole lot easier to achieve.
Would a grove cut in the case half-mounting face for O-ring material be an effective oil seal?
Yes, it is done on some high end race motors, it’s good when they come apart fairly often. I won’t be doing it on this motor, my spindle is far too slow for a 2-2.5mm end-mill. It’s also costs in more time and material than cutting out a paper gasket.
@@OddsandEndsMachining If you ever reconsider you might be able to rig up something like a dremmel to get the spindle speed high enough.
@@2000freefuel I’ve thought about using my trim router as an auxiliary spindle, but that’s on the very long to do list.
Get a Datum point...
Leave the Datsun that's on point fo l8r bro
What's the difference between a mill and a mehw? It looks like mill.
At last... someone is doing something useful with a Tesla.
This is cool but you're losing the gearbox and clutch. Board track replicas accept classic preformance to have a classic design. Gonna go with no brakes like they used to? No throttle just cut the ignition to reduce speed like they used to.
Bro shut up you’re being completely pedantic. Go find some other corner of the internet to shout your empty complaints.
I think the final application for this engine is a bit different to what you’re thinking it is.
Just remember to not stop lying!¡!
