This is my first crack at this so I hope this goes well, apologies if things are otherwise. So here's the deal:

My intro Solidworks class has been tasked with designing siege machines and my group chose to use springs to supply the force. I've managed to come up with a crude design for the frame but don't know how to attach the springs in the assembly.

So the arrows point to where I want to attach the spring. This isn't how they will be attached in the end, but I figure if I can make this happen I'll be well on my way to the final design. Any help would be much appreciated, again apologies for missing information, picture quality, general disorganization etc.
