The Story Of Coffman Corvette
Continuing with the Corvette convertible top story we come to Coffman Corvette. Honest, this isn't a paid endorsement post. Just an interesting story I learned about a family business involving a father and his son. There are some similarities to Mr Johnson and his sons and Johnson Welding and Repair.
This family business was started decades ago by Ernie Coffman. Ernie, passed away unexpectedly in 2012 at age 62. With his passing Coffman's Corvette is now run by his son Clint. As the business grew it was moved several times over the years to ever larger facilities. Finally the company purchased the turn of the century, North American Watch Company factory that sits on top of a hill in Mansfield, Ohio.
This is the view you see as you approach the front door. Not quite what I expected a Corvette restoration parts manufacturer to look like.
Shown above is part of a large addition to the left of the original stone factory building. This addition was done in the 1960's or 70's. Overall it's a large facility encompassing some 70,000 square feet. They now have room for the necessary equipment to manufacture more Corvette restoration parts.
Closer to the front door and evidence of refurbishing the old building is evident. The windows have been replaced with more energy efficient ones, the foam insulation showing around the window frames. Stepping through that door...
...reveals the original, magnificent, elaborate, wood trimmed staircase. On the other side of the entrance hall...
...can be seen a fireplace and...
...a glass display case that contains, among other Corvette related items...
...a section of wall from their old shop that was cut out and transported to their new shop. That wall section is the place where
Zora Arkus Duntov,

Elfi Duntov, had autographed the shop wall. Zora is widely considered the "father of the Corvette" and greatly revered by the Corvette world.
Walking further into the building you pass by...
...some of the office areas. BTW, that's Clint's mom Pam, facing the camera, still working at the family business. Note the tall ceilings and that huge window!
Clint graciously gave me a tour of the shop. Just some of the equipment...
...we've previously seen this 2 story tall, 50 ton press. Just a sampling of other equipment...
Here a jig is being used to produce...
...these frame assembly body pivots. Next they will bent and machined.
One of the smaller fabrication areas.
Once this frame section is cut out, shaped and bent, it needs holes drilled and counterbored...

Corvette convertible frames are complex mechanisms. These side frames are especially difficult to make. Note they are left and right sections. A complex shape with odd bends and precise hole placement. Clint uses original blue prints where ever possible.
This is just a fraction of the tooling and machines used in Coffman's operation but you get the idea. I hadn't realized everything that was involved in the manufacture of these folding top frames.
Beside constructing new frames they can restore existing frames such as mine.
Here a frame section is being checked on the body jig...
...as it is being restored.
Some of the parts inventory.
Coffmans makes dozens of parts and Clint tells me he uses only USA made steel for all his parts fabrication and is committed to working to the highest standards.
My personal observation is they do just that.
