Armor CAD Drawings

[George McKenzie]

I was thinking that would it not be possible to get coppies of the CNC program of the armor for the fellows in Canada and other parts of the world .I hate to think of what the freight would be to ship the armor .I live 3000 miles from some of the fellows in eastern Canada .I have counted over 30 carriers in Alberta alone that don't have armor. Richard, my MK2 has the original front armor and center bulk head .But I wonder how accurate a measurement I can get with it in the carrier .

Shaun i appreciate where you are coming from, i cant recall the exact figure for getting some made by the firm but it was well into four zero's...i cant afford to throw money away like that, especially when i would need the materials freighted up North too.

i have access to all the machines i need to make a set at a cost i can afford i only require acurate dimensions and reference to what size hole, which are counter sunk etc etc etc.

perhaps if the firm were to give a discount on a set at a reasonable cost i would reconsider my options but thousands for mild steel does not compute in my tiny Geordie mind......i am too close to scotland and by reputation they are froogle with their cash hehehehehe

Hi the firm i used to make my armour did quote a four figure sum but that was for the frames and ALL the top armour not just the front when you start to look in to how much work went in to the parts its not as simple as stright cut plates. i wish you all the best in making your armour and trying to put it on CAD but you carnt beat an original patten to work from like we used.
For those of you who have purchased a carrier in the condition shown in the attached photo i would think unless you are a compleete lucky GIT (richard lol ) you would be talking four zeros not including shipping thats only half a carrier the tops what makes it look like a carrier then you have the cost of rivetting, carriers are not a cheep toy like people think oh its only a box on tracks how easy would that be to make? I can tell you all i have spent well over 15k on having all the linkages and bits and armour made and thats not included in the purchase of the vehicle and then i was mad enough to make a new one on top of building this one that alone cost just as much to do. i wish you all the best with your builds just sorry i carnt help with the pattens my fabrication firm works on £30 ph and cost +20% you do the maths and tell me if thats too much to pay for parts when you see the finshed item ?

totally hear where you are coming from Martyn......But......... i now have access to a pucker unmolested Mk1 with complete armour which i will verify the measurements with.

once i had what i felt to be accurate drawings i was going to get my pal to machine patterns out of ply wood (same thickness as the steel would be) from this i was going to retro fit it to the carrier to make sure it fits then from that make any adjustments required on the drawings.

another thing to consider folks is yes in the end i may produce plans for us all .......But....... as Martyn quite rightly pointed out you will need to get it rivetted by skilled people.......and also what needs to be considered is the top armour forms alot of ridgidity (spelling?) for the hull, when this is chopped off it is my understanding that the tub can actually twist which makes fitting new pannels somewhat problematic. problem is you probably wont know until its fitting time.

prices for mild steel (up here north) are very reasonable at present but i have no doubt they will sky rocket back up again (hence why i need to move fast)


as i say if the firm were to arrange a cost for a bulk purchase ie say six sets perhaps a group of us could club together.....but...... as the carrier fraternity consists of isolated clusters around the globe, it would be a pain for the Canadian and Australian clusters to pay and ship.


like anything guys it has pro's and Con's but what i would like to politely suggest is those that need armour should speak up and share their views.....those with armour obviously can give opinion too.

Martyn could you perhaps provide a cast iron (forgive the pun) quote for a set of armour and perhaps center bulkhead (as most who need armour need this too)




then people can weigh up :-
A) how much they can get the raw material for
B) have the ability to take drawings and make something that will be correct and fit their prospective hulls
C) have the time to do it themselves

or

A) get it done through the chap who did yours and

B) ship it home

I am one of those unlucky ones with cut down carriers. I would be interested in good drawings of the armour. If the alberta guys can make it cheap enough I could be into buying some. I get out to Edmonton at least once a year and could pick it up. It would knock years off the restoration to have it already pre made! I'll keep watching this thread.

right unfortunately i have found that the drawings above are not correct to a 1942 Mk1 canadian carrier specification. i am going to have to go on a road trip to see a pucker mk1 methinks !

i measured my armour remnants and came back with the following

so on my 1942 canadian UC Mk1

rear and side armour plate is 8mm

front armour is 10mm

Glacis plate 5mm

center bulkhead 5mm

good news is that i have DXF'd most of the plates so once i change the parameters they should be ok for CNC use
