I couldn`t find any exact dimensions or ready-to-print templates for a standard strat neck pocket. I am a begginer and have a strat neck, and want to make a custom body for it.
Can someone supply me with a ready to print file so I can then glue it onto wood and make a routing template?
I thought about that but I am afraid that it might come out too big, or not precise
Trace your neck on 1/4" mdf, then cut & sand it to a perfect fit to your neck, then make a working template in 3/4" mdf, make sure you make the template long enough so the router doesn't run out of room when you get to the edge of the body.

why not just buy a routing template? all this hunting around for stuff to print to make a template seems unnecessary.
