Hello James .
Would it be possible for you to video a cleft being pressed?
It's a very impressive job you have done.
I recall you saying you had an £800/£900 budget, did you come close to achieving this?.
If the funds were limitless, would you have been able to streamline you're design to enable it to become even more portable?.
Once I get a bit more proficient at it I'd love to video for you.
Budget wise, I'm afraid it was well over as well as time scales. The old adage 'estimate your price and double it' is more than apt here. My advice to anyone wanting a press 'BUY ONE' if you can.
Having said that I do have a press that I know every nut and bolt of which I'm sure will count for something.
I think making a press 'portable' would be possible but would depend on your definition of portable. I have already found that the limiting factor on my press is the motor. It is a 1.5kW 1400rpm single phase motor geared at about 6:1 and will stall if you try to press too hard (far too hard in reality - 5-6mm in one go but this was testing and experimentation) The mechanics of everything else are more than strong enough. However, with each pass of the cleft you need more force for the same amount of depth of compression because you are compacting the cleft each time - if that makes sense. Therefore, you still need to be able to achieve the same power of compression regardless.
