Outstanding episode. You should have thousands of subscribers. I have had a mill, lathe, etc and a foundry for a while. Finally took the plunge and bought a 3d printer and am learning CAD and G-Code. Next step is probably a cnc router to do exactly what you are doing here. Keep up the good work!
Thank you, I will get there eventually if people enjoy the content. i was in the same boat as you about a year ago. I only learnt Very basic G code for this. I rely on the Fusion360 CAM to write it all for me, learning how to do this properly takes a while. Have a look at the NYC CNC vids they helped a ton when I got from the CAD to the CAM stage.
The downside to owning a Milling Machine or Lathe ? Buying, Everything else you Need to actually make it work. It does take time to build up a reasonable amount of gear to do the job right. But that's all part of the fun of machining. Great to see the progress on the engine build. Looking forward to watching the next video. Peter 👍
That is some excelent work rigt there! I also had the same ideat but I dont really have money to buy milling machines. Seeing someone doing this is just amazing. Very nice job and good luck with next projects 👍.
You can use crank and heads from honda astrea grand from 90s to take 200cc easily and primary gears from z50 1971 with 18-67 gears for much higher speed. And maybe 4 speed gearbox from honda c59 glx or lifan
Hey there my Kiwi cuz. We share similar interests. I started doing utube videos over a decade ago, but never really got around to doing any more. My homemade furnace was used 2 days ago to cast a replacement router base for a bosch pof500a.. also love your references to cheap chinese products.. One of my vids is about chinese knockoff Dremels.. I'm subscribed mate. Keep the vids coming and i wish you all the best 👍 Paul, from AU
Beautiful videos and workmanship man! I can't wait to see how this plays out!! Any chance you'd sell an engine case in the future? I'd be really interested in buying my own little v twin out of some parts engines I have and one of these cases
@@OddsandEndsMachining id definitely want them pre machined if the prices isn't too nuts! I'm not at all setup for any kind of milling. I've just got a small lathe.
Thanks, i’m sure the subs will increase, I just need to upload more frequently. The design took far longer than it should have although I was learning how to use fusion 360 as I designed the pattern. Maybe it took about 3 months of occasional modelling on the pc after work. The casting and machining the patterns could have been done over two weekends. Machining the cases doesn’t take that long, maybe a weekend for each half. But being my first time it took a lot longer as I had to fix lots of small design flaws and sort out how to tension the cam chain amongst other small challenges. For reference, I’ve started another engine (not the V4) and the design is close to finished after 3 weeks. I think I’ve developed a bit of a process now.
I’m sure it could be done fairly easily. You’ll just need a bunch of Extruded polystyrene foam and either hand shape it or draft it up in some CAD software. Then get someone with a large router to cut it out.
Thanks, i got the sand and gib 4 plus plaster from bunnings, same with the foam. The aluminium was old Honda engine parts I had kicking around. I’ve never bought any real casting supplies haha.
If you mean to make this motor so far it has cost me around $21 for the sand $22 for the plaster $25 for the foam $0 for the scrap aluminium $270 for a brand new donor motor $150 for another new cylinder, piston and head The are a few other small things I haven’t added up or gotten around to yet.

amazing project !
Coming along very nicely 👍👍😎👍👍

Can I ask you how much was the cnc mill or where did you bought it? Whats the name of it?
Thanks you. It’s an Optimum MH28V, it cost $2,800 nzd. The conversion to CNC was about $1,000 or less.
It is similar to a grizzly G0704

Simply amazing! 👌

Thank you. I could do another set in the future, would you be wanting to machine them yourself of have machined cases?
@@OddsandEndsMachining id definitely want them pre machined if the prices isn't too nuts! I'm not at all setup for any kind of milling. I've just got a small lathe.
@@brianmosleyb9104 that’s what I was thinking. I’m trying to figure out what the price point for something like this would be to make it worthwhile.
Very nice. Any idea how many hours you had in at this point? Surprised you don't have more subs as the content here is great..

can you cast direct shaft 2 stroke engine for ultralight aircraft
it may help us to move by your casting guide

That casting is fucking amazing! I cant even cast a cube without bubbles in the shit. Where do you get your casting supplies in NZ?
Thanks, i got the sand and gib 4 plus plaster from bunnings, same with the foam. The aluminium was old Honda engine parts I had kicking around.
I’ve never bought any real casting supplies haha.
Amazing result with what looks like just bedding sand. Did you video your small CNC mill build?
I’ve only snapped a few photos of the process. I’m pretty bad for filming things I’m doing, it’s a miracle I’ve managed to film this much haha.
How much would it cost to modify this motor?
If you mean to make this motor so far it has cost me around
$21 for the sand
$22 for the plaster
$25 for the foam
$0 for the scrap aluminium
$270 for a brand new donor motor
$150 for another new cylinder, piston and head
The are a few other small things I haven’t added up or gotten around to yet.
