"What a mould looks like" Topic

Just in case any one was interested.

Or half of one at any rate!

Wow I don't think I have ever seen so many location studs in one mould!

I love moulds like this – they're almost works of art. Remind me a bit of the crop-circles that we get so many of in these parts. Mine, on the other hand, look like they've been cut in with a knife and fork – aesthetically disastrous although usually functional.

Did you make this one yourself, Michael? Kudos if you did.

Give over Doug!
Very kind of you to say so though.

It does have a certain appeal does it not.
Hypnotic almost…

Must be said it doesn't slip much!

This is a Griffin Moulds one.

That's no mold, its a dimensional shift anti-wobbler, I saw one once in the Tardis, kid you not. ;-) I've a few molds myself (9 inch round, and its a dogs breakfast compared to this one) Cheers

i must admit i use lots of locating studs, it does make the mould stay in the right place and not have too many slipages!
nice to see i am not the only one who crams as much into a mould, no gaps.

Having loads of old moulds I keep thinking whether it's worth framing and selling them.

Blimey that's the weirdest mould seen for a long time ( well apart from one or two of my own of course lol). Why?
I'd have thought that many studs would cause more of a problem than solve any, those are wee bits so not a lot of slippage gonna happen with those. Use 12 or so myself.
Is it not a mould at all but really some sort of Martian time portal? :o)

Could be a hub cap?

lol@Angel

I'd agree with all that Leon said. I only use 8 studs myself and don't get slippage issues.

I have never seen a mold like that in my life !!!

We can use that as a wargamer's mandala.

The basin, runners and gates look very professionally cut but there are very few vents. I assume it casts OK?

Casts very neat indeed.

as well as about 8/10 studs I pre-cut wedges out of one side every6 cm or so this creates matching all rubber locators & I get zero movement even at high speed & low pressure.

I can't fault Griffin's moulding or casting. They've done stuff for us that I thought can't be done in one piece.

Same here Simon.
In fact one regular 'wargames company' said one of my models can't be done, another tried, messed it up and destroyed my master in the process.

Griffin did it fine.

How much did that run you?

The mould was £60.00 GBP from Griffin.

That is also what my other moulds from other companies cost, seems to be the standard over here.

I recall a 'conversation' of some years ago with one of the posters on this thread who insisted that there was no such thing as 'slippage', but judging from this exchange it would seem the word is common parlance among manufacturers, and that the phenomenon it describes is much as I'd assumed.

That's no mould…. that's a space station!

There is slippage in hydraulically clamped spincasters. The ram pushes up the motor/drive shaft from uderneath, clamping the mold by pressing the bottom plate against the rubber, which then presses against the top plate. When spun up, ALL torque goes from the shaft, through the rubber, up to the top plate. The top plate is forced to catch up, and the inertial lag can cause slippage. So its a combo of clamping pressure, and having enough locks in the mold to prevent slippage.

The only way to avoid this, would be a way to ensure both the top and bottom plate spun up at the same time, but it would much more mechanically complicated.
