I have laid out transition curves using the stick method several times. Don't use a square stick as it will break. Go to the local lumber yard and get a piece of screen molding about 8 or 10 feet long. It is 1/4x3/4 and if you check the grain when you get it, it won't break. Mark the curve with the offset for the easment at the end. Set three nails on each side of the tangent line slid the stick on edge between the nails and bend it to your radius. Hold it and mark the line. That is your center line for the track. It will automatically set the easement. Easy and cheep.

It's really not all that hard to line them up, and certainly much easier to use if you are trying to locate a curve to join two tangent tracks. Set the template a little inside and then use the bent stick to make a gentle transition at each end.

Hi Charles, Anyone who's worked in construction has no problem with using a tape to swing curves. Just drive a nail at the radius point then hook the tape on it( the common pocket tapes even have a little nailhead notch on them) then hold your pencil against the tape at the desired radius and swing away. For layouts where the radius point falls in an isle I just clamp or screw a temporary board across the isle then drive the radius nail into it. If the center falls inside a wall or other inaccessible place I'll make a template from scrap sheet material or even cardboard by swinging the arc on the template material then sawing it to the curve. If using a template some care must be taken to make sure the centerline falls on the correct alignment and that it is squared up with the tangent tracks coming and going.Templates placed end to end without proper alignment can create unfair curves with unwanted angle points.....Dave Branum [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] ------------------------------------ Yahoo!
