Armor CAD Drawings

[Rick DeBruyn]

Richard I’ve been fortunate enough to track down 4 Mk1’s. Between the 2 almost complete UC’s I will be able to obtain all “un-molested” measurements needed to produce armor for the cut down units I have.

It would be nice to have a couple users/owners from the forum double check my measurements, what is the forums unit preference; Metric or Imperial? I used Imperial assuming that was the original units used back in the 1940’s.

As I previously posted, I noticed some unexpected slight rivet-hole differences when measuring the side armor. I talked to Rob L. & he thought it was probably due to inconsistent flattening of the rivets during manufacture…what do you think? As suggested in a previous post, the most accurate solution would be to remove the rivets from original plate to get the factory “specs”.

As you can see from the photos the UC’s are rough and in need of a lot of “elbow grease”, also I will need to obtain fair bit of newly manufactured & NOS parts, etc. to finish them up. I plan to have at least one done by next summer for the “Alberta parade tour”.

On the contrary Rick they are four gorgeous vehicles !!! and iam green with envy ! i think your right about the rivet holes, and i can only suggest that the plates are drawn up without them ? that way they can be drilled on the carrier, failing that if you used teh mk1 mortar carrier the frames are all still in situ so should get spot on dimensions for the holes from that i would think. i have the blanks at my place now but my car failed its mot so have had to drown my sorrows with a £400 fix it bill. will have the results for you tommorow as i still have remnants left i should be able to see if the plate fits or not

Ok here we go this is how we did mine, make the plates drill the plates as best you think, offer them to your hull tack weld them in place, then build it up bit by bit after your happy its all going to fit weld the front behind where the frames would be, take it off and then make your frames,then mount the frames and drill through your plates on the vehicle its the best way to make it.

and its always best to go from experience cheers Martyn i suppose from carrier to carrier the holes and rivet types could be different depending on what the carrier would be used for.

Rick:
Your carriers are gorgeous, they are far from rough shape. Most are cut down to next to nothing. You have a very nice collection there. I look forward to seeing your progress on them.

Eric, you being from Thunder Bay do you know Don Barrie ? he is a collector of carriers and a great chap, he was kind enough to sort me out with my carrier (sorry to go off on a tangent guys)

Rick i fitted the templates on the sides and they appear spot on i took some pics however my pc is dead so i have had to resort to using my mobile phone to access the web ! I have a query on the gunners side where the armour drops (where it meets the front cockpit) it lines up spot on with the center bulkhead plate can you check this on your carriers ?

[Rick DeBruyn]

The side armor stops flush with driver side of plate #; CTL 13284 (Plate - division – corner) as you can see in the photos. I’ve included my updated side armor drawings as well. I believe the drawings to be fairly accurate however I leave them open to the forums critique. I’m working on the bulkhead drawings I will provide them when complete.

I’ve been provided with the cost of side armor cutting, the quote is $105.00 CND funds per side. Steel will be an extra cost. Does the amount sound reasonable (this will include rivet holes)? How does this compare with other suppliers?

[Rick DeBruyn]

Finally…we’re starting the laser cutting of a few plates, and covers for the carriers! All the measurements were taken off a Mk 1 carrier…perhaps anyone who might know what parts are interchangeable with a Mk2 could comment.

The laser cutter company is ready to cut both sides (CTL 12774 D Plate - protection - L.H. & CTL 12775 D Plate - protection - R.H.) and is waiting for quantity. The cost per side is 220.00 CND funds for pick up in Edmonton or Three Hills Alberta, Canada. The plates will be cut to dimension and have rivet holes cut out. If you’re interested you can PM me or email to stuff4rick@gmail.com.

I have provided the below original parts to the laser cutting company, they are confirming measurements will then format part drawings and I expect quotes shortly, so assess your needs and I will provide costs as they come in.
