Want some tanks or armoured cars - especially unusual types see
http://www.landships.info/landships/models.htmlCan be easilly rescaled for example (from an article by Chris Appoldt), if you want to build a 1/48 scale tank for your aircraft diorama but only have 1/35 scale drawings, simply divide the scale you have by the scale that you want: 35 ÷ 48 = .7291666.
Now round up, leaving you with .73 Adjust the decimal placement to 73 (you’re moving the decimal because on the
photocopier, 1.0 = 100%, 1.5 = 150%, etc.). Now just set the copier to make copies at 73 percent, and you have your plans in 1/48 scale. To do the reverse and enlarge 1/48 to 1/35: 48 ÷ 35 = 1.37 Now round up, giving you 137% to
enlarge the plans by. Two popular armor modeling scales, 1/35 and 1/76, might complicate matters – most copiers will copy no smaller than 50 percent, and you’ll need to reduce further than that. To convert 1/35 scale to 1/76 scale:
35 ÷ 76 = .46 (or 46 percent) Now, since we can’t go lower than 50 percent, determine the square root of .46,
which is .68. Set your copier for 68 percent, copy the 1/35 scale plans, then copy those reduced drawings again at 68 percent. These will give you the 46 percent reduction, and your plans are now in 1/76 scale.
