Watching this is very interesting ....

I was a bit worried the plugs wouldnt come out but they did without too much damage.

A wee bit of compressed air down the part line usually helps but I don't want to be telling you how to suck eggs.

I dont mind if you do, there arent many forums sharing what you have learned.

Just finished the top of my copy mould , worked out OK
So far so good, its quite rewarding stuff, not too dificult and easy to get amazing results

[Flettner]

I call it " therapy "

Pour a new mould from the core box .................
The original parts used to build the core boxes are on the shelf never to be used again unless somthing gets very wrong and I need to remake the core boxes.

Looking at the mouldings (which you have just poured), - are they made using casting resin?


Yow Ling,you're coming along well, - have you got your furnace etc. in operation? - mine has been delayed yet again but it's nearly there.

Hi Will, I got the furnace going last christmas, Ineed to make a couple of tools to handle the crucible and get some sand. Ill try and get those things sorted this week

[Flettner]

Yes, mouldings are of casting resin. I'm missing the rear port (I'm onto that tonight) and then the water jacket core. I'm not too sure of that just yet, could be a little tricky as the water inlet to the cylinder (RG500) is from the rear, not under the exhaust as you would expect. But we need good flow around the exhaust port. Might need some guide thingy's in place? And I've just realised this cylinder will need new heads as well, one head per cylinder, not like the originals. This cylinder is designed to have a gate valve in the exhaust (power valve), not the original drum valve to a volume in the head.

I read some where Wob talking about cooling water goes into the head first then down the water jacket and exiting at the exhaust was the way to go. No sense in trying to cool the head with water that was pre heated by the exhaust.

Got all your gloves aprons etc? - I've still got to make tongs etc too, and I hope to really get stuck in and finish the furnace sometime soon, but I'm having to look after the grandkids etc. and the workshop really isn't the place for them!

I was impressed by the videos by Myford Boy etc, he just gets on with it and says basically nothing!- I've got them all downloaded now.
There are a lot of contradictions between the various enthusiasts, one good example is the use of steel crucibles for melting aluminium, I think I'll stick to the ceramic ones and avoid any problems!
I am hoping to start with smaller stuff ( model engines) and maybe work my way up to bike stuff, will see how it goes.

Must say the stuff we are getting from Flettner is top notch and I'm learning a lot here. I think this bike forum is really very good, - I'm not venturing into the wider forum much as yet though! ( mainly because I'm out of my league with bikes these days!).

I have been following Neil but how the heck do you fit in those swooping transfers with the RG500 spacing's. It must be a little tight and challenging is it?

Anyway this is the one piece DEA RG500 heads molds.

Guess the flow of colder water near the transfers before it hits the exhaust isn't such a bad idea!
Never did think the drum valve and the cavity was a very good idea - probably created a lot of extra heat round the front of the cylinder, well that's my take on it anyway!

I think you're probably right, maybe leave the exhaust till last!

Hi Husa, are these your molds?

[husaberg]

Hi Husa, are these your molds?

No they are a mold for a RG500 with individual heads.
On a net troll the other day I seen this.

I are starting now to realise why Neil suggested to do a metal tool though.
Can Neil talk though the process?
