Any 'smith that lacks common business sense won't be around long, at least above the radar that is. Sure, business equipment, tools and tooling and most other business expenses should be utilized at tax time. But, ya' still gotta' have "cash in hand", to write the check, when that insurance premium is due, you need to replace a tool or buy another to keep your customer happy, and many other unseen required business expenses . I think few who work for a company realize how much they're actually being paid beyond what the pay check says. Companies provide insurance many times and paid vacations. The employer is also responsible for half of the amount paid into S.S. as well as having Workmans Comp insurance and having a safe place to work in. The self employed get to pay the full amount themselves and provide that health insurance for themselves and their family. I would suggest that anyone who thinks that $250-$350 is to much to pay for a custom barrel install start up their own gunsmithing operation or , maybe just find another 'hobby' that is lower in cost. Current shop hourly charges at the local car dealerships is $125/hr. At the 'independents' it 's $85 (I think). The local plumbers and electricians are at $85+ and charge another $45/hr for the 'helper', with itemized charges for everything. The 'hobbyist', that "flys below the radar", can charge less. No FFL, no ITAR Registration fee, no liability insurance, and works for 'cash' only and work for a company that provides "benefits" during the day. Most gunsmiths aren't getting rich, but they shouldn't have to live like a pauper, either. If you doubt it, just start up your own operation, one that's a legit small business.
