BUCKRIDGE FLINTLOCKS

This lock is over 2 centuries old. Originally hand cut, each part is designed to fit ONLY with the pieces in this lock. Each feature of each part, was created relative to the mating parts. In other words, if something wears out, breaks or is lost, there are no replacement parts.
My job is to parametrically duplicate this priceless assembly so it can be reproduced by the family owned Buck Ridge Flintlock Company.

Please check them out at ​https://www.buckridgeflintlocks.com/ and tell them I sent you.

Individual Parts​

Hammer

It may look easy, but don't let the finished product fool you, the hammer was by far the most difficult part to reproduce. It is not symmetric and each organic feature changes relative to it's rotation on the Lock Plate.

Frizzen

This part actually looks harder than it is. Most of it is symmetric. The most difficult feature was the small, turned up feature in the lower right.

Plate
The plate holds it all together and everything aligns to this one part. It looks simple enough but hides many secretes.

Sear
The sear is a critical part that teeters on the edge of dainty but this coupled with the tumbler are perhaps the most critical for safety and consistency to the whole system.

Frizzen Spring
The frizzen spring is a fairly simple part to model. We kept the sculpting detail because it's beautiful.

Main Spring
The main spring is also fairly simple. The detail on the top is also beautiful and it was a pleasure to duplicate organic detail carved into metal 200 years ago.

Tumbler
This is perhaps my favorite part of them all. The tumbler is the heart of the system and truly a thing of wonder. Clearance and high resolution features along with tempering always amaze.

Top Jaw
The top jaw holds the flint in place. It seems quite simple but it shares some special secretes with the hammer and I'm not telling.

Bridle
The bridle holds the tumbler and sear to the plate. This cute little plate takes many forms. While it's not very intricate in this assembly, they are often ornate and decoratively beautiful in many locks.

Current Project Status:
Picture
The 3D printed parts were used to generate tooling for casting. One of the parts (not telling) must be machined for specific material properties relative to function. 
The stocks are new and custom to the new product launch. These will be made in house at BuckRidge Flintlock. 
I'm genuinely excited to the launch of this new product and I'll be one of the first in line to purchase one.
