Machinery

Hello, As the New 40k Apocalypse rules are out, I decided to make a huge Kiwi Titan (Titans are ridiculously large mechs). The bcenter of the body is going to be made of MDF, with polyStyrene filling, then plastery stuff, and as that is wet, I am going to stick about 1000 1cm long, 1mm diameter then use spray on glue to secure them. So to go with my Maori Theme, I am going to need a whole lotta machinery parts, preferably plastic. I am mainly looking for large hydraulic looking things, leggy joints or anything that could pass off as a mech leg part. On top of that I need plastic tubing, about 1mm dia., 40k guns from tanks, tank parts, tank tracks, vents etc I have alot of metal 40k Marines I have for trade (About third edition, ranging from apothecaries to standard bearers) and even down to guns and random marine parts. I aslo have the odd terrain supply stuff...But free stuff is good
