Cargo canvas size wanted to know.

Great job there Scott!

Just wondering, what is the hesitation from buying fron New Life Canvas. I don't run a canvas cover on my truck, but may someday.

As a Vietnam motorpool vet, all you guys seem to have done your homework. It's amazing how precise you are. After 6 years in the Army, I couldn't have come up with better numbers. I've got to say, we never worried about size or how it fit. Throw it over the bows and tie it down, and hoped it stayed on. GREAT job, and it looks great!

Here's more (whether we need it or not, just trying to get this accurate):

Numbered duck
If a piece of the cloth 36 inches by 22 inches weighs less than 19 ounces, the cloth is called numbered duck. The grade of numbered duck is calculated by subtracting the weight in ounces of a piece 36 inches by 22 inches from 19. For example, a piece of #5 numbered duck 1 yard by 22 inches would weigh 14 ounces (19 − 14 = 5). The bigger the number, the lighter the cloth.

Numbered duck is nominally made in weights from 1 to 12, but numbers 7, 9, and 11 are no longer used. Some typical uses of various weights are:

#1 hammocks, sand bags
#2 hatch paulins
#4 sea bags
#6 large boat covers
#8 clothes bags
#10 shower curtains
From http://www.sizes.com

Here's a quote direct from a supplier of mil. veh. tops and covers:

We use mil spec #8 duck for all exterior canvas and #10 for interior canvas as per the original specifications. Number Duck is subject to much more stringent weave and strength requirements than ounce duck.

Any website that tries to impress you with weight of canvas is either using inferior ounce duck, or has limited knowledge of the subject matter. Weight has nothing to do with number duck (other than the fact that it can be thrown on a scale and register some unimportant result).

I will double check with my supplier again about that.

I am still confused about the width. I am going to measure the top frame again right now. I got 142 again. Just between the ends of the corners (the exposed 'bent' wood) is 44 inches. From that point down each side to the bottom of the upper side bed lip is 49 inches. 49+49+44=142 inches.

Here's two photos of the bows installed just to look at if I did anything wrong:

Everything looks kosher. The troop seat uprights measure 22 1/8, and the bed lip is 2 1/2 inches. The troop seats sit vertical with the bows installed. The corners and bent wood are NOS, and the staves are exact replicas of NOS one Jon gave me.

Binford: The only thing missing is to actually measure one bow assy. installed on your truck. I've really bugged you enough, but this width one is pretty critical. Is it possible to throw your troop seats on and one bow and measure it? I could bribe you cash and prizes. I know it's a PITA, but somethings not the same between our trucks.

Let me know what you can come up with if its not too much trouble.

BTW, militarypotts: the reason I'm doing this is that I can get this done for at least half of what the dealers want. (I hope....)

Fantastic reference info...great stuff Scott!!

My troop seats are hanging on the "garage wall" (Costco tarp-canopy!), but I need to pull the wood slats off anyway and refinish them as the urethane hasn't held up as well as I anticipated. I should have some time today, or at worst, this weekend, to check that for you.

I put the troop seats on and stuck a top support bow in:

Then I measured it, from the bottom of the bedrail on the outside to the same point on the other side, running the tape continuously (number-side in so it would go around the corners properly) and got 141 inches. Very close to what you and Ken found.

So there ya go....


I also found that I had run over one of my corner pieces. It had rolled out from the side and I must have run over it when I pulled the truck out last time.

:blowup:

Thanks for sending the measurement. I am going to have the cover made at 142 inches and see what that looks like. I'd rather be too long than too short, maybe.

I'll get this info to my supplier and see what I get.

Sorry about your corner, Binford. I hope you can straighten it out without too much trouble.

I see you put your stave stops to the inside of the stave. The 34p manual has them on the outside. I see inside would leave less the cover could rub on. My bow assy's. are bowed out, so the stops hit on the outside of the pockets. Hate to have a point deducted at the next MVPA convention......

I'm anxious to hear how this turns out. I'm interested in getting a cover for mine as well.

Just curious, will this end up cheaper than New Life Canvas?

How's it coming Scott?
