Armor CAD Drawings

[Rick DeBruyn]

Hi all,

Thank you for the excellent information & discussion.

Since my original post I have been in discussions with a local fabrication shop, which among other fabrication activities have a steel water cutting machine which they say is accurate to 7/1000 of an inch. I am going to deliver 2 of my (fairly complete) Mk1’s to their shop they will produce cad drawings then water cut the plate.

If any would like to add their name to the list we could collectively lower the production costs. Email me at “rick@aztecinspection.com” . The fabricator is in central Alberta, Canada.

I will keep the thread updated as to how the production proceeds (with costs) as I am advised from the fabricator.

Before I give the go-ahead to the fabricator to cut the plate I would like to provide the CAD drawings for comment from any that are willing to double check the dimension accuracy (please email me if you would check).

I plan to give the attached side armor drawing to the fabricator to assist in their CAD drawings (more to come as I can measure and produce them), can any comment on its accuracy? As I measured the rivets there seemed to be slight differences from carrier side to side and even on the measurements from the same side…perhaps the problem is that in the riveting process they (rivets) don’t flatten completely central to the drilled hole.

Thanks, Rick

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.

right, the college have cut out two blanks for the side armour, so i will collect and try it on the carrier, at least i will be able to accurately plot the bottom holes but cant help with the uprights as they have all been chopped off.

Thanks for posting your pdf. If they are accurate, they will be really helpful.
Cheers.

Rick, are those two carriers yours ?


I have collected the blanks so i can hopefully get them retro fitted tonight and post up the results tomorrow. I am confident we can produce something accurate for the large numbers of people in our predicament


"the system works"

What you need is a propper set of front armour thats not on a carrier?
Good luck with your templates richard hope they fit?

[RichardT10829]

very generous of you to offer these up for measurements Martyn, are you going to post up the measurements or shall I send kevin a crate of booze in payment to pop over and measure them up

secondly is this british armour or canadian as i am told they are quite different ?
