Omikron starts to take shape!

Just finished cutting the main parts of Omikron's chassis. Overall they match the CAD nicely so far, and I am quite happy with how they have turned out - I tried an alternate method of marking out the HDPE this time around.

Eoin's post on the FRA forums suggested printing out 1:1 scale drawings of my parts and then sticking them to HDPE sheets. This provides a guide on which you can easily cut with a jigsaw. Before I would measure everything and manually draw lines with a permanent marker. This was always a bit of a pain as trying to see black marker on black plastic isn't easy. The curved parts on top would have been very difficult to match without the printouts. I also think it will be super useful when it comes to drilling. So overall this method gets a thumbs up from me!

Also got out the angle grinder and began work on making the pins that hold the leg linkages together. I'm using the un-threaded sections of m4 & m5 socket cap bolts, held on with shaft collars. I didn't fancy using regular bolts and nuts as I want a smooth surface for the legs to rotate around. I also want the legs to be easily removable for repair, whilst also unlikely to screw off in a fight.

Now to get these parts on my pillar drill and get drilling!
