I’m not sure just how much pressure we’ll be using to compress the blocks. So I’m spending extra time reinforcing the far end. I would hate to be wrapped up in making a block and have the end fall off. There’s a formula for figuring out the lineal pressure that is generated by the circular motion of the acme thread. I’ve looked at it and it makes no sense to me. Hopefully an engineer will google the formula and then send me numbers and I can pretend I’m smart. One inch ACME thread 4 threads per inch.
I wanted to attempt a bottle brick/plastic block tonight. I was just too tired. I’m going to try to hit it early in the morning and maybe we can get one just to see if it will work.
I tacked in the brace for the ram rod and it’s a little off. So in the morning I will break the tacks and align it better. I will add bracing and then attach the ram to the rod. I still have to make the handle for the rod. There’s a part of me that likes the idea of a steering wheel. I’ll probably forgo that though and settle for a slip rod handle
The ram will never make contact with the end of the box. But to get the density we think we’re going to need the force against this end will be like the ram hitting it. That’s why I’ve put in all the steel.
Keep in mind that if this thing works this is open source. So if a company wants to send a thousand of these to Haiti for instance then they can get the measurements from mine, have their smart minds modify it for efficiency and manufacturability, then they can have it made anywhere, India, China, Canada, USA. Another thing is anyone can modify it and make it better. I just hope that if they do they share it with the rest of us.
