Well it might be, but there are numerous instances where people ask for information when a simple search reveals everything.

Grow a sense of humour Eddy I was clearly having a Bleedin Joke.!! . . . . . . Clue was at the End. .

Well, gavztheouch seems to have left the premises so we will never know if it was bleedin' obvious or whether I should have pointed him at the other one

Cheers Robin, I have seen that site from a previous post you made on another thread. Ebay is also a good place to find parts for molds there are a few chinese sellers selling ejector pins, springs and bushings, I dont have a link but they should be easily viewable.

Thanks for the heads up on purging deisel I was not aware of how toxic some plastics are when burnt or that you should not mix certain plastic together for safety.

The rabit takes molds bases that can be made on the lathe ie. cyclindrical not square, at some point someone has modded the machine to also accept bigger square or rectangle molds. The machine came with a manual with some basic dimensions and mold making tips. I will try and scan some important pages and see if anyone can help me work out how to cut the injector gate on the rear of the mold.

Any ideas on how best to machine this gate entry in the mold, the mold is cylindrical so I can use a lathe.

I can see 4 components to the operation,

1. 1.1mm hole
2. 4mm radius
3. 60 degree bore?
4. 90 degree bore?
