Making Coil & Flat Springs

Bob Dunlap goes back to the bench to give you hands on instruction on the design and manufacture of coil and flat springs.

Now you can make those springs for the odd jobs that always seem to pop up. Obsolete guns can be saved and used again.

We’ll show you how to figure out the size of the spring you need, how to wind it and how to temper it to get a long lasting professional part.

You never know when you will have to be able to make a spring for that
special project gun you got a deal on or just to keep your guns working
in future.

Learn the secrets and tricks to making flat springs
in this one-hour course instructed by master gunsmith Bob Dunlap. Take
ordinary spring stock and fix those firearms you just can’t get parts
for. This professional course is AGI’s latest offering for the gunsmith
and experienced hobbyist, but belongs in every gun enthusiast’s
collection.

Bob takes you through the process of making a hammer
spring from scratch. Includes metal selection, heat-treating methods,
shaping springs, “color tempering,” and more. This will save you years
of trial and error.
