Scale conversion help

Hi Nico
I think that I am correct . 1:29th scale is 0.776 times that of 1:22.5
so converting your measurements form 1:22.5 to 1:29 will be
260 (x 0.776) x 400 (x 0.776) x 280 (x 0.776)

To make it easy you could call 0.776 just 0.75 that would be near enough
 
22.5 x (your measurement) / 29 should do it.

ie. the easy way to think of it is to convert the original scaled length up to full size, then back down to the new scale.
[edit] or use 22.5/29 = 0.776 as beavercreak says.[/edit]
 
on another problem that i have are you any good at knowing an angle for a roof from a picture i cant post the picture here as its from a well known maker of buildings its a roof of a white barn:cool:

Are we talkin' 'poko' barn here Nico?
 
Its all to do with sines and cosines - the whole lot I learnt and forgot!. If you know the scale height of the building and width you are part way there, so half the width gives you one side of the triangle, then if you know the height of the roof from the eaves, that gives you the vertical line (and a right angle too).

I'd just draw that on a piece of paper and then draw the other line (hypotenuse) to complete the triangle. Forget calculations - just use a cheap protractor to measure the angle or just scale the vetical and horizontal measurements.

Eason's sell them I think.

its not a straight forward triangle im afraid,:thumbup:

What formula is used to convert from 1.22.5 scale to 1.29 scale
example 260X400X280

Divide each number by 22.5 and then multiply by 29....

... but that would make each measurement larger than it was. 1:29 scale is smaller than 1:22.5 so I think the original solutions by beavercreek and myself are correct.

Sorry about that Nick/Nico?

I was typing that when I was called away and didn't check before posting quickly.

Perils of tryng to multi task....
 
As in my first post, just multiply the 1:22.5 measurements by 0.75 (or use 3/4 of the measurement), that will give you what you need (near enough as damn-it).

As to the roof...I have the barn in question, still as a kit in the box, so will get it out later on and measure the apexes for you.

it is multiply by 22.5 (getting 1:1) then divide by 29.
