One thing I was worried about was drying it... Any tips?

Lots of compressed air.Comment

Sealed the leak. Also discovered that all 3 of my valves had crud in them so had a little clean out and now it's working well. I think that could have been the problem all along...
Had a test with half full buffer tanks and a traffic cone.

Flips well but makes some funny noises- in the video you can hear that after the inlet valves fire something continues to hiss. I wonder if this could be the ram leaking?
As you can also see there is quite a bit of resistance in the "to atmosphere" valve. Is this just because I am not running it al full pressure? Or is something else going on that can be fixed?Comment

Hi everyone,
Life got in the way of this project for a bit. I'm trying to find some more time for it now...
Is there a way to calculate the optimum position of the ram re:leverage? Is 4:1 ALWAYS the optimum?
CheersComment

No, the 4/1 isn't always the optimum. It depends on the ram and the flow.
A long stroke ram will use a lower leverage. A short stroke ram more, if it has the force to do it.
For Gravity3 I went for a 4/1 ratio to keep the force on the tip around 1 ton. Just felt right, and it was then. This means the flipper was powered up to 720mm .
In Bullfrog, I still aim for the 1000kg on the tip, but the ram is so different that the leverage is closer to 7-1, with a powered stroke on the flipper around 400mm.Comment

Hi, sorry for taking so long to reply to this, other things have got in the way of hobbies!
I'm sorry for being thick, but what would the drawback be to having a 1/1 ratio?Comment

Almost finished! Got the drive and flipper going. Still need to fix down things like the buffers and stuff- and then I'll try to get some videos. http://i.imgur.com/ZLVTrjW.jpg
Cheers for everybody (and Mario's) help. I'm sure this wont be the end of my questions
