Cutaway Engine

[LeonV]

Cool, sounds like an awesome project! Definitely post some video when you can!

Excellent! That is fast progress. Impressive.

I guess you know an LD28 cranks gets ~$400 on the street here in North America... get a few of those and your project is fully funded if you can freight them across the pacific

looking forward to seeing this Brian

Thanks for your constructive input Blue. She runs quite happily on 1 2 3 as you suggested.

LD 28 cranks are quite sort after down here as well. Some of the race guys are running strokers, and with good success.---$400 US for a crank?--Lordy we are sitting on a goldmine down here. These diesels came in to NZ in the eighties in second hand Japanese imports, so they were fairly common, but getting scarcer.

Hi Tim. Come to the Intermarque Concours at Ellerslie in Feb. and God willing, we and it will be there.

Merry Xmas all.

Dang you must thank yourself... you did the real work and succeeded! Congrats!

Now from your theoretical 3 cyl. mule to an applied 3cyl. mule:

Your next gas-compressor in your garage will be an L28/2.

Just connect the rear 3 spark plug holes and rear three exhaust plenum out to feed a 1-way valve to your tank.

Thinking outside the square. Thats a damn good compressor idea Blue.:bulb: Unfortunately I don't have the space.

"Yet" There is always "down the road":)

Here is a link to the engine running. Due to excessive bearing clearance, it has a bit of a rattle on start up, until a bit of oil pressure builds up. and it is not as loud as it sounds. The camera seems to amplify the noises.

Excellent! So much better than I imagined. Even the cool red paint on the cut-away block detail.

I am very impressed. Big pat on the back.

Man, that is just plain cool. Not being picky or anything, but is that a sink trap you are using as an exhaust pipe? Looks like there may still be a hair clog that needs snaked out.

VERY NICE, Brian! Beautifully executed!

Hey, FAIW, I bet you could run your cutaway engine much slower with a large flywheel, but otherwise as-configured. You could probably run it even slower with the large flywheel by using only a single cylinder. Maybe you could close down the SU butterfly completely, and drill a tiny hole in it to regulate more precisely at an extremely low idle.

That said, yours is one of the few cutaway models I've seen that I can actually see the parts moving in less than a blur.

Yes it is indeed a sink trap 5thhorseman. Dang it, I thought I had got all that hair ball outa there!!

It's actually the muffler( a ball of brass pot scrubber held in with a couple of wires going through the pipe.)

Thanks for the thumbs up folks.

Sarah, your flywheel idea could be good. I don't want to increase the diameter, so would it have the same effect just to add more weight? I could bolt an extra flywheel to the existing one, and that would not effect the starter operation.
