Plan enlargement ( Here we go again!)

I have some plans I’d like to enlarge to 1:20 one is 1:87 HO another 1:48 O and the last is 1:160 or N. I tried a search but came up empty.

HELP

Matt,

Ok what I found was current scale divided by the scale you want times 100 gives the percentage to copy the plans at so…

HO 1:87 87 / 20.3 * 100 = 428.6%
O 1:48 48 / 20.3 * 100 = 236.5%
N 1:160 160 / 20.3 * 100 = 788.2%

at least that’s how I read it. Hope that helps you out.

Later,

Jack

The lady at the copy place here in town could only go 50% ata time, which means I had to refgure what their machine could handle.

Matt, the easiest way is to measure the original plan with a (HO, O,N )scale ruler & then build your model using your 1:20.3 ruler. 15ft in HO is 15ft in 1:20.3 if you use the correct scale ruler.

Matt,
Was’nt there a thread earlier regarding this? Thought I recall something on enlarging. Later eh…Brian.

Brian,

That’s where I got the info from it’s “Copy machine enlargments” in the pull out plans forum [html]http://www.trains.com/community/forum/topic.asp?TOPIC_ID=23569[/html]

But I do like Phil’s way you wouldn’t have to have the plans re done unless you really wanted to build on top of them.

Take care,

Jack

The reason i want to enlarge the plans is for several builds. First being a couple of Bobber cabooses based on prototype which are drawn in 1:87 or HO.
The Other is for my coming closer bash of a Bachmann 4-6-0 into a 2-6-0 mogul based on some Cooke mogul drawing and want to be able to copy as close to the proto type as possible and capture the feeling proportionately . I’ve seen sdeveral done on MLS and they are close but I want it to be as on the money as a bash can be. The 1:160 or N is for a building to see how much room would be taken up to see if it’s even feesible for a given space.

I guess when it comes down to it I’m a finer scale minded modeler just doing it with large scale outside.

Matt,

There’s nothing wrong with that! I know personally when I start building things, I’m probably my own worst critic, just because I know where the things that aren’t quite right are. Good luck with your builds hope they come out like you want. [:)]

Take care,

Jack

See if you can find a commercial reprographics company in your area, they should have the equiment to do the larger xeroxing jumps, but you might want to consider a photographic process, xeroxing get fuzzy , stretched, warped and out of square the larger you make it. A photo englargement like a PMT process will keep everything square and hopefully in scale. A commercial reprographic comany is your best bet.

Vic thanks, would I look under printers and such or a blueprint Co.?

Matt,
Sounds interesting. Let us know how you make out. Later eh…Brian.

I would look under a blueprint company, they should be able to handle anything.
