Where did you find that

Will, 2 to 2.5 % I think works best. You can go to 3% but I think that is just wasting the sodium silicate.

Googled "cover of rocket man"
pretty sure he slaughters a few more songs as well.

Is that by weight?
Does the sand need to be rammed as hard as greensand?

Yes by weight. Rammed but not real hard, about as tight as you can push with your fingers.

Thanks, might try that tomorrow, probably I'll have to adapt my Sodasream equipment to be able to control the gas for this purpose, I'm sure it would be a bit too forceful as it is!

Very nice, are you open to mail order sales ?

Ever read Nevil Shute's "Trustee From the Toolroom" ? The title character makes eggs of different colours for a kid - which as well as different materials are different heat treatments of steel. Nevil Shute Norway was a pretty good engineer too.

Yes you are, you pervert. I didn't even know those 'tools' come with stabilizer fins.

I Suspected as much,(that i was a pervert) Winglets were the in thing for 2016.

I know this rocket project is way off topic but two things. I enjoyed making these for the grand kids, second thing, I was posting the making of this rocket pattern as a 'see how cores and core prints work' and the reason for the beads. I still get asked why the beads and I thought this would be a simple pictorial explanation of the process.
Glen, I don't know what you are talking about
Anyway back to cylinder making. Next cylinder will be an almost normal one.

I may have to rewind, I missed something somewhere! - don't really understand, remember I am a very straight granddad, I grew up on a farm and had a sheltered upbringing! but I do know that all the animals managed fine without all these accessories, like rockets, porting tools, etc.

Oh, and Neil, regarding the rockets - make sure the grandkids don't get to hear all the untruths and insinuations being bandied about!

Seriously though, showing just how those rockets are made is a a good simple learning exercise for those lazy sods who are interested, but can't get themselves to have a go at casting - they could learn a lot from it!

[Flettner]

The cylinder I cast with the rockets.

[WilDun]

The cylinder I cast with the rockets.

Silly question maybe, but did you have to knock the cores out to get them to that stage or did they just crumble and fall out?

[Flettner]

Cores will break down with heat, largely crumble out but water blaster helps.
A gaggle of rockets.

Was going to do some more slider exh welding in the arvo after finishing off another job, but when it got to 42 deg @ 4.30, I decided that some other less heat intensive things would be the go. Must be getting weak with age.

[Flettner]

Ken, much hotter and you almost won't need to turn the welder on to melt metal.
Good things come to those who wait, look what Santa dropped off.
Let the HCCI continue.
