Announcing a new design of spring vise for big locks, and now it functions with medium and small springs! Right hand locks only.

Here is a large lock, with a long mainspring. The elbow of the spring is in the ‘U’ of the vise, and the swivel foot of the screw is centered on the tip of the spring. Tighten the screw until the spring can be lifted out of the lock. So simple.

Large spring

Shown below is the large spring compressed and lifted out. At this point, you can unscrew the vise, and put your spring aside. Easy enough to re-compress and install it.

Spring out

There is a middle screw location for smaller locks, such as the ubiquitous Siler, and others. This idea came from Jim Chambers when we were discussing one of the prototypes. Great idea, this position adds so much versatility.

The innermost location can be use for frizzen springs and cracking pistachios. This location was suggested by Eric vonAschwege on one of my earlier versions. Thank you, Eric.


Years in development, and after many versions, this tool is the latest version of a long-needed vise for removing gunlock springs safely. Safety for the workman and protecting the spring from breakage, were the biggest concerns in the design. A critical design consideration was the broad range of locks and springs that need to be compressed and removed.

This design of this vise grew out of a need to manage the large and powerful gun lock springs that started coming out on the market, notable examples are Chambers’ Round faced English locks and R.E. Davis’ Colonial locks. These are long and mighty mainsprings, that need to be handled with care, and removed with a proper vise.

Thankfully, Jim Chambers was willing to partner with me to produce these units. They will be available from Chambers Flintlocks on line and at shows. We will carry some at the shows we attend, to sell and demonstrate their function. If you want to order them by mail or phone, call Jim or Barbie Chambers.

I attend the 18th Century Artisan’s Show, Dixon’s Gunmaker’s Fair, Contemporary Longrifle Association show (CLA). I try to have vises in stock, and carry them at shows.

Price of unit: $40 each, plus $5 shipping and handling, and any applicable sales tax.
