If you're not 100% sure of how a heavyweight hydraulic crusher goes together, you maybe better starting with something simpler and working up to it. What you're attempting is about as complicated as it gets.
Hello,
I agree it's a pretty ambitious concept
We have the support of our engineering company, and we specialise in machinery, so are confident on the mechanical aspects. As for the electronics and hydraulics we are not so familiar, but are all willing to learn and hope you guys can help us

This is a quick sketch of the 2 stage concept, the red part being the electric motor, and the green square the shot bolt
I am thinking the hydraulics can possibly run a small cylinder for the shot bolt.
We have contacted a few companies regarding specs for the pump and are waiting to hear back
The motors and speed controllers went on order yesterday, so in the month lead time we hope to purchase the batteries and RC unit so we can get a test chassis up and running.
The OptiPower discount looks like an awesome deal, so will probably go through them.
Is there anything we are missing in terms of having a working test chassis?

These are some of the test pieces we have experimented with to get to grips with some of the forces we need to work with.
The claw was a test laser cut piece to fit in the manual press to try a pierce then slice type of approach, but it failed pretty quickly.

We modelled up an arm to FEA and get an idea of weight and managed to get down to 18kg with an 8tonne force at the tip and 40mm alu.
The distance from pivot to tip is 500mm and that is a m20 nut on the top for scale.
