The Bucket Foundry

[WilDun]

Good!
We've now got a couple of commercially experienced people (with different approaches to the challenge of course) to give us amateurs some guidance and ideas on "how to" -

Kawasaki is restored to race winning form. Well it's all back together again and it even started up second kick, imagime that. Is it fuel injected? I don't know, you will have to ask my office as I was on holiday in Hawaii at the time
Should be able to get back to the cylinder pattern next week.

Have you ever posted pics of the lake injector carb you made Neil?

[Flettner]

Um, I'm not sure? Perhaps this picture? Kawasaki used to run a lot of wires in the air intake?



This is by far the better system

[Flettner]

Sorry, as you were, I was just happy to have the Kawasaki going agian, back to foundry stuff, hour meter has just flipped over 60 hours, on EFI.

Far too many wires in there , looks like trickery to me. Saw the inside of a vw TSI motor yesterday, injector straight into the combusstion chamber, looked trick 1400cc turbo and supercharger 8 bent valves @$80 each ouch

Made some resin castings from my mould today, did 3 , first one disaster, 2nd ok but kinda shitty, 3rd was acceptable. these 2 I will cast using investment method, I may try and do some in greensand . Here is a couple of pics from todays efforts

Guess you'll be trying lost wax for your investment trial?

A few days ago, I tried to melt some plastic (milk bottles) to mix with wax but the trial was a little inconclusive - I had to abandon it as I was using my wife's new stove and the house was getting to the stage where I was going to have to go outside in order to breathe!
I had to leave all the doors open for the rest of the afternoon to remove all the evidence! - not a good thing to do in this weather!
Back to the drawing board.

Hi Will, not using wax. I have set the parts made of casting resin into plaster like the Canadian guy did, I will fire that block of plasterto get the resin and the foam risers etc out thenpour into the plaster/sand block. I think I will cook it outside, can't get into so much trouble out there.
Sand will be easier to do than this, but I have to try stuff, there is no way in the world you can get good at this by watching youtubes alone

I don't really know, but I would be inclined to check whether or not the resin would burn out cleanly as opposed to plastic, maybe you should try it and see how it burns (ie how much of an ash residue it leaves behind) before trying it out in a mould, - not that giving it a try is going to do much harm of course.
I certainly wouldn't contemplate operating a furnace inside!! - the amount of heat coming out of those things could cause untold problems and I think the insurance company would not be impressed either!

Better make sure your boundary problems don't become an even bigger issue as well!

I have a couple of hours of unsupervised time this morning so I put my investment mould in the furnace to remove the resin patterns. its a bit smellier and smokier than I thought so I have to hold my breath when I go check it, Im going to cook it for about an hour and see later how it went. If it goes ok Ill cast it on Sunday

Pity you couldn't have cast it while the mould is still hot though.
Anyway, that looks like a good furnace, I'm sure it's the beginning of many happy hours in the foundry! good luck, but just be careful to keep on the right side of the neighbours!

Any joy with your first attempt?

[Flettner]

We have gears, 360 engine, and a crankshaft.

[F5 Dave]

Neil you project finisher. Stunning.

[Yow Ling]

bears engine, will it have rear facing exhaust ?

I better just go to the shed and sweep the floor
