Innovative Vertical-Feed Annealing Machine from Giraud Tool
This report was first published in 2011. Due to numerous requests, we are republishing the story. The time is right because the Giraud Annealer is currently on display on vendors’ row at Camp Perry. Doug Giraud will be at Perry through the morning of August 4th.
Doug Giraud of Giraud Tool Company has created a new bulk Cartridge Annealing Machine that uses an innovative vertical hopper feed. Giraud’s patent-pending design allows the machine to process as many as 700 .223 Rem cases with no hand-feeding required. The new Giraud Cartridge Case Annealer, using a single propane torch, will anneal most cases in 6-8 seconds (that dwell time will melt 750° Tempilaq inside the neck). Annealing dwell times can be adjusted using a simple rotary knob on the right side of the machine. During annealing, each case is rotated in the flame through the motion of a Trolley Plate which moves right to left under the case. At the left-most limit of Trolley Plate movement, each case drops vertically down for air cooling. CLICK HERE for Giraud Annealer Users’ Manual (PDF)
The Giraud annealer uses a large, V-shaped hopper to hold up to 700 .223 Rem cases or 450 .308 Win cases for annealing. You can switch from small cases to larger cases by swapping out the rotary Feeder Wheel below the hopper. Changing Feeder Wheels takes a couple minutes. Five available Feeder Wheels (with different size cartridge slots) let you anneal pretty much any size cartridge — from .17 Remington all the way up to .50 BMG. The common .223 Rem and .308-sized cases used by High Power shooters are served by the Red Feeder Wheel and Blue Feeder Wheel respectively. The Blue Wheel will also work with 6mmBR, .243 Win, and .30-06 cases. The three other Feeder Wheels are: Black (.300 Win Mag); Purple (WSM, RUM, RSAUM, Lapua and Norma Mags); and Green (.50 BMG). For the large mags you also need to switch to a wider Trolley Plate.

Giraud Annealer Can Process Hundreds of Cases in One Session
The biggest advantage of this machine is its ability to run with minimal user “intervention”. Once you’ve determined the right dwell time for your cartridge type, you can stack hundreds of cases in the V-shaped hopper, turn on the torch and let the machine do its thing. With a typical 8-second dwell time, the Giraud annealing will process about 450 cases an hour. While other multi-torch annealing machines may be faster, Giraud prefers the single-torch design: “With a single torch, you can control total heat input over a longer time. You don’t over-cook the case in a half-second — you have a lot more leeway with a 6-9 second dwell time.”
Yes the case spins in the flame — the Trolley Plate running under the case rotates it. The user may wish to experiment with the speed control knob on the right side panel near the power switch. Typical annealing operations will require the cartridge cases to be positioned in the torch flame for between 6 and 9 seconds.
Much smart thinking went into the Giraud Annealer design. Doug Giraud tells us: “We went through a couple different ideas. Our key goal was to vertically stack a large quantity of cases that would self-feed. The automatic feeding capability of the machine means that the operator can perform another task while the machine is running. The user doesn’t have to load cases one by one. I would caution, however, that you don’t want to turn on the annealer and just walk out of the room… but you can be doing some other reloading task while the annealer is running nearby.”
Giraud wanted a machine that could process lots of cases cheaply and efficiently. The machine’s single torch is optimized to run on inexpensive propane gas. Doug says: “You can process 15,000 cases on a single $2.00 disposable propane bottle.” If the user wants faster processing, the torch is rated for MAP gas, but Doug cautions that, “with more heat, you’ll have to adjust the dwell time accordingly.”
Giraud Annealer Impresses High Power Shooters
The new Giraud Cartridge Case Annealer has already attracted considerable interest. Doug took some early production models to Camp Perry in 2011, and he immediately got orders for 50 machines. Doug told us: “The response from the High Power guys was amazing. There was a pent-up demand for a simple, robust annealer that can process hundreds of cases without having to feed them one by one, and that’s what we created. We’re selling these units as fast as we can build them.”
Giraud Annealers Cost $435.00 — Delivery in Six Weeks from Order Date
Doug has components for 100 more machines, and he’s producing them at a rate of 15 units per week. He’s been back-ordered, but if you order soon, Doug believes he can ship the Annealing machines in about six weeks from date of order. The basic price, with one Feeder Wheel and one Trolley Plate, is $435.00. Additional Feeder Wheels cost $20.00 while extra Trolley Plates are $10.00. For more information, visit GiraudTool.com.
