Tips on measuring a radius
I am looking for a way to measure a radius on a fender Iam making a pattern off of I has a gradual radius and my radius gauge doesn't have the exact match Iam looking for a quicker/easy way to find the start the middle and the end of the radius so I can map it out on my pattern and duplicate it on the new panel. These are some of the things I struggle with when making patterns

I use radius gauges like those pictured. If the curve is to long or too severe I make it in several pieces and then fit them to the panel and clamp/staple them together.

I make paper patterns both whole and in segments, like Norson recommended. The handy shortcut for me to copy a profile is to use a gauge like these: http://www.tinmantech.com/html/profile_gauge.php

Thank you for the feed back, I usally do use a straight edge. I have a profile gauge that I got from the home improvement store, it's not as nice as the tinman ones. I'll try to snap a picture of the radius Iam having a hard time with its a very gradual radius

Another option between the cheap home improvement store version (I've got a couple of them..) and Kent's nice one (don't have one of those yet)-
Years ago I ended up with a small contour-radius gauge made from a stack of index card weight cardstock. There are heavier top and bottom exterior covers. The cards are slotted, with two? long thin bolts & nuts passing through it all. Loosen the bolts, fit to the contour and tighten the nuts. Because the cardstock leaves are so thin in comparison to other contour gauges I've seen and used, it registers really well and won't scratch a surface. Measured length is around 3" iirc. Always thought I would make a larger version, ideally from comparable gage sheet plastic instead of actual cardstock, when I felt like punching lots of holes and trimming slots. but I haven't yet. I also use multiple patterns (trimmed paper, cardstock/chipboard and numerous existing patterns) in unison to record & duplicate a profile.

this is the contour gauge I use for the curve I think you're describing.
