The Bucket Foundry

A bit complicated for me

Even has something on casting

Four cylinder heads, one 700 twin crank case lower half (with balance shaft housing). Also cast four drum throttle bodies for Wayne Blackwood but he's taken them home to cut the runners off ready for heat treatment.
Yow Ling, nice ban saw, free? Nothing in life is free.
Ideal'y the tilting plate in front of your disc sander should also rise and fall to expose more disc for the big jobs. Normaly it's on center.

I guess you are right , not totally free , just didnt have to hand over money, I made a chuck backplate for a Hercus lathe, got the saw and a RS125 frame in return, so maybe he is in credit a bit still

Just like that!
I dunno, what some of you guys would do in a couple of weeks, I'd take a couple of years to do! - (but......I'll do it!).

Don't worry Will it's taken years to get to this point.

A sand core cylinder kit set ( minus the boost port core, that was a cock up ), this is for 350cc cylinders ie for the 700 twin.

That's quite a solid looking machine - you got the good end of the deal there!

Outside segments for the cylinder mould.

Neil,
Gotta say once more I'm impressed. Well done.

Question. How long do your CO2 moulds last, ie did they go crumbly in a day or so? Maybe we stuffed up with ours.

Materials. LM13 for your cylinder


.
Have attached some info here. The one called OEC Equivalents is a cross reference between different coding systems of alloys. The others are spec sheets for LM13 and 601. 601 is a very common high grade aluminium used for many auto specs inc blocks, heads and wheels, to T6 specs usually. We used this at Orbital for basically all major engine components.
Other attachments are just some with more basic info. Happy reading Will, but don't let this slow up your progress!!

Alloy wheels can be easily sourced from wreckers or even a clandestine raid.

We used this for our prototype cylinders and all ARC kart engine castings.

Ken, the most part of the 700 twin cases are CC601, but the cylinders will be LM13, all post heat treated.
I was going to take pictures of the cylinder mould being assembled, but forgot untill it was done.
700 twin crankshaft halves being machined out.

Right, here we go from start to finish, putting a cylinder mould together.
Packing the mould box in sections

Pictures say it better than I do

[Flettner]

Ready to pour, just need another fine day for the out doors foundry.

[Flettner]

A nice evening for a cast.Once the flashing is removed and the castings cleaned up a bit they will look proper.
Moulds are sitting on a steel plate with gas burners underneath to drive out any moisture, pre the pour.

[Yow Ling]

Well that was quicker than a cezarian, and twins as well !

[WilDun]

Well, just getting to bed (a late night for me) and I decided to have another look throught the thread - I'm gobsmacked and almost speechless! (unusual for me) - great stuff!

Thanks Ken for the info, learning a lot from you guys.......... and no, I won't be slowed down - would that be possible in my case?
