from what we discussed via email the measurements provided on the rough drawings were all wrong (for a canadian carrier anyway) i produced dxf's but they need corrected with size etc i spent little over a week making them, but without the correct sizes from an unmolested carrier they are a risk of being slightly out. It will be easier to drill the plates on the carrier as per Martyns method, what would be good is the water jet could cut out the center bulkhead easily and all the viewing visors on the front armour. keep me posted Rick but if you have got the outer dimensions of the plate done the rivet holes are easy enough. when i measured the remnants of the side armour (minus the rivet heads) the holes were 10mm and the counter sunk diameter was 10.8mm but i could not measure counter sink depth as my vernier is missing.
send me what you got dxf wise matey but if you have got the outer plate measured right, it will save me a 5 hour drive to Kevins house to measure his canadian armour
i will try and get some ply blanks cut from your current spec's and try them against my carrier.
