Home-brewed Coping Gauge
 

Today, we ran into a screwed up compund angle going into the backside of a bend when piping the wastegate into the downpipe for a srt-4. Didn't have coping tool, so we came up with this. We just used some 1/16 TIG rod, zip ties, and the diameter pipe we needed. Ghetto?..............damn right, but it worked out really well.

Not bad
