For Machining:

Raw Materials:

1. 1/4" Thick 316 Stainless Steel Plate
   
2. Fin Preform (FC002). For testing fit. 

Tooling and Machines:

1. 1/8" Coated Carbide 3 Flute End Mill for Stainless Steel (McMaster  8883a11)
2. Mill (At least 5000 rpm and set up for mist of flood coolant)

Fabrication

Machining

Machining stainless steel is difficult. Do not expect the process to go as smoothly as machining aluminum. If you have never worked with stainless steel before, ask for help, expect to break an endmill or two, and buy extra stock and tooling because you will probably need it.

I. Making the Blanks

II. Machining the Slot

1. Secure the blank in the vise. 
2. Set the speed to 5000 rpm, the feed to 9 ipm. 
3. Turn on the coolant.
4. Plunging 1/16" at a time, cut the slot. Power feed is your friend.
5. Once you have reached the desired depth, test the slot width with the Fin Preform. Run .005" finishing passes until it fits snugly. 

III. Machining the Taper
