I'll give the run down of what I did -
Helmet - typical fiberglass Royal guard helmet - shoulders trimmed back for the more tapered
v look is a must
- sand, paint, sand, paint - you get the idea

Chest & back - TK front - custom made back from a tk
Shoulder bells - TK - cut in half raised section removed, re-assembled and made seamless... then trimmed to measure - the template Lucious talks about helped - but again you'll need to scale it to you.
Ab plate - again custom made - sintra - made to my scale - note the hole - that's for the buckle to go into - keeps thing tight.
Gauntlets - custom made from scratch out of sintra, measured my forarms - had a rough idea and went at it - they must have the ...I'll call it sweep at the front and the back - I think you know what I mean

Belt - standard Tandy Blank, so was the buckle itself - Grooved the belt using a jig made for a table saw - worked great - Center piece - simple made to scale out of wood
Shins - ala Jango style - but symentrical - again custom made from sintra and scaled to me.
