Hi Callum,

If you bring the drawings you have to a scanning service and get them to scan and print at the scale factor you require. You say you have ''full size drawings'' but obviously these are scaled drawings to fit on a drawing sheet, the scale of the drawing should be indicated in the Title Block of the drawing.

Knowing the drawing scale one can then calculates the scale factor you want them printed at, the printing service will have to print the final drawings over several sheets as 1 to 8 ratio will be a large drawing for a loco that size!

Hacketts may be able to help, give them a call......

Yes, that's them. You may have to shop around as scanning & printing large scale drawings can be expensive!

Hi Callum,

Thats unfortunate there is no scale given. All draftsman should indicate a scale on drawings. Thats a sectional detail drawing you show, sometimes these can be drawn full size, my comments above related to a full loco general arrangement drawings or say a drawing of the chassis only.

But I see figured dimensions on that drawing, so you need to get out your scale and measure the dimensions to see what scale the drawing is. I hope you are familiar with using scales and have a few,  the dimensions are imperial so you need an 'imperial scale'
