User Stories
Testimonials from Smithy's happiest customers
No Wait Time With My Smithy
"I have a granite 1324. I run a job shop outfit that does machining work for plastics manufacturing companies. My customers sometimes have orders with 2 or 3 day turn-around. I work in aluminum, plastic, and brass. What I enjoy most about Granite is the lathe work. It is really easy."
-Hai David Nguyen, L.K.B TX
More Convenient for Hobbyists
"I use my Smithy to make or modify parts for motorcycles and antique guns. I'm in this as a hobby. The Smithy probably has paid for itself but I haven't kept track. What is more important to me is the convenience of making my own parts, exactly as I need them when I need them."
-Kerry Klein, MI
Support Leads the Way
"I looked at other machining equipment but chose Smithy because of the quality, size, and availability of tech support. It's compact yet it does the work of larger units. It's a lot of machine that takes up a little space and it will pay for itself in the long run."
-Danny A. KY
Better Than a Grizzly
"After technical school, I did an apprenticeship in clock and watch repair and in tool and die making. I'm retired now and run a busy clock repair shop with my Smithy. I make parts for older clocks, cut clock gears, and make the cutters as well overhaul clock repair tools. I purchased a 9" x 19 bench lathe from Grizzly but returned it because of poor quality. I chose Smithy for its Sturdiness, its milling capabilities, and its compact size."
-William V-R., GA
No more down time
"Wendell and his business partner own a small textile factory. Last year, a German sewing machine clutch broke and production stopped. They weren't sure how long it would take to get a replacement part or if they could even find one. Putting their Smithy to work instead, they had the sewing machine back in production the same day."
-Wendell(Owner of Small Textile Company)
