Dave, in terms of the paper weight I need to convert to grms, so when you mention the weight in lbs are you talking bond or text. I'm guessing the latter?

Not sure I understand what "bond or text" means.

65lb cardstock is 176gsm

110lb cardstock is 199gsm

...or thereabouts, depending on the brand.

I prefer "CARD STOCK".
I don't like cover stock, its coarser/raggier.

Not certain either!

Most of the paper conversion charts quote different types of paper when in lbs, including bond and text.

The problem is this....

Metric paper is constant in terms of thickness. In other words 80grm paper comes in a constant thickness which does not change. The imperial paper however relates to lbs for 500 sheets (I think). This is not constant, and different thickness of paper relates to different lb weights.

Very complicated. So bond paper is heavier and and thicker then text paper, which for less lb for 500 sheets is therefore thinner. I assume the latter is normal typing paper.

Never been able to sort it out properly. Need a micrometer probably to do it properly. Or maybe need to weigh metric reams of paper accurately!

Sigh. ???

OK, bit the bullet and ordered it, plus the accessory, (plus the vehicle accessories while I was about it !!!).

You can retire now in luxury!

I'm just stating my preference for "card" stock, over "cover" stock
which is very similar, but different.
.
And my Wausau and Staples brands 65lb card stock appears to be fairly consistent in thickness (.22mm - .23mm)

In designing, I round up to .25 including glue
...and so I usually allow .3mm tolerance for a single sheet and .5mm for two layers.
This also compensates for the extra thickness of 110lb cardstock, which is around .25/.26mm

I am constantly using my micrometer.

...
thanks for your purchase!

You purchased the Little Willie model and the Steering Carriage add-on?
Good for you.
Even though Wilie is displayed in the Museum without it, adding the Steering carriage makes for a nice display.

What "vehicle accessories"?

Automotive Accessory Kit. 1/18.

It's years since I made a Revell 1/25 model and I quite fancy  one, when I can find or order one, with the garade trimmings.

---------------------------------

Back to Little Willie. Need to do a bit more figgering out re the papers thickness, and will then try  to source it. The next challenge here. May have to resort to laminating. In this place they take 240 grm paper, split the reams and sell it individually as board at about 55 US cents a sheet!

Anyway, the project will give me something to think about for a while before I start!

OK dave - have thought about the paper a bit more.

--------------------------------------

I have found stock of 160grm paper which I guess will be OK for the 65lb card stock. About .17mm thick.

Or again for the above I can laminate 80 to 100 to give 180 grm.  About .19mm thick.

Though I am not keen on the laminating issue at all - had plenty of issues in the past, so would rather prefer the 160gm paper straight. Would this be OK although the card is slightly thinner?

--------------------------------------

The 110lb cardstock I will have to laminate - say 2 X 100grm. About .24mm thick.

Yes? Feasible?

Paper? (169gsm?)...only .17mm thick?

There is no way its the same type of 176gsm "card stock" that I use...its way too thin.
As I mentioned, my cardstock is more like .23mm.
Yours may have a similar weight, but thats unimportant.
Even the cheap cardstock I buy for throwaway jobs, is that thick. (Rougher surface, but still that thick)

I would be concerned about the thickness and strength of the paper for some parts (because of the scale).
If your paper is rigid enough, it might be okay...but thats generally why you want cardstock, and the thicker card.
You need that rigidity.

Little Willie's Hull panels need to be printed on 110lb cardstock (at least .25mm) and then laminated to a second layer.
A minimum .5mm thickness is closer to the proper scale thickness of the real boilerplate.
You also need a white interior...the inner layer gives you that.

There are a few other larger parts that need to be that thick also.
Like the Track side plates.

The Frame (Chassis) rails are double thickness for strength and two-sided colour
...but you can use 65lb (176gsm) card for those.
It will fold a little easier.
But the double layering is necessary for thickness and rigidity for the frame.

Where exactly are you Kevin?

ah...so I have heard of other Africans and their paper/cardstock troubles.
Sometimes we forget what is available in different areas of the globe.
Not everyone can get the same things.

Please, follow my suggestions as far as card thicknesses.

If the card you have is only .17mm thick, then you could try laminating three layers?

But if you can get proper "cardstock" (not coverstock or business card material) at 176gsm and 199gsm
with a thickness of about .23-.25mm...that is what I suggest.
