inexpensive steel calipers designed for reloading use. We
have found that they are
not accurate for our use and tend to come apart. We
recommend you purchase
6" Starreft dial caliper approximately $125.00 or
6" Mitutoyo caliper approximately$100.00. If you are
unable to find these let us know and we will purchase them
for you.)
If you take the
barrel fitting school only the cost for parts, tools, and
tuition is $1010.00. If you are taking the barrel
fitting school and the 1911 school together the cost is $560.
The reason for the difference is that you will have purchased
about 1/2 of the tools for the barrel fitting school as part
of the tools for the 1911 school.
