APPLYING A BAKED ON TEFLON/MOLY FINISH
ITEMS NEEDED:
A propane fired campstove
A coat hanger
An electric drill with bits
ITEMS TO BUY:
1 can - Brownells Teflon/Moly Oven Cure Gun Finish, Cost about $20
1 can - Degreaser
2 sections - 6 inch stove pipe
1 - 6 inch stove pipe cap
1 - metal handle for a screen door
2 - small eye hooks with nuts
1 roll - aluminum electric fence wire
1 - candy making thermometer
BUILDING THE VERTICAL OVEN:
Put your two sections of stove pipe together. I believe these are two foot sections, so you should end up with a 6 inch diameter pipe approximately 4 feet long. Measure the diameter of the shaft of the candy thermometer, and drill a slightly undersized hole near the middle of the 4 foot section of pipe. Insert the candy thermometer. The metal handle you bought should have a hole at each end of it for attaching. You will be attaching it to the top of the stove pipe cap. Mark where the two holes line up, and drill these holes using a bit the diameter of the two eye hooks you bought. Take the two eye hooks, and insert them thru the holes in the stove pipe cap and the holes in the handle. Attach the nuts to the threaded shaft of the eye hooks and tighten it down. The eye hook itself is on the inside of the stove pipe cap, and the nuts are on top, holding the handle onto the stove pipe cap. Take a short section of coat hanger and attach it between the two eye hooks on the inside of the stove pipe cap. You have just built your vertical oven!
PREPARING THE BARRELED RECEIVER:
The barreled receiver must be thoroughly degreased. Aerosol cans of degreaser can be bought at any auto parts store. Spray the gun good and wipe it off. There will be some parts of the barreled receiver you will not want to have the Teflon/Moly spray to get into, so tape these areas up now. These areas are: the chamber and bore, the four holes on top of your receiver for attaching a scope mount, the holes for the receiver bolts, and the trigger. Just leave the receiver bolts in, and that takes care of that. I used a section of a wood dowel that I inserted in the bore to protect it, I cut up sections of Q Tips to insert in the receiver holes, and I used masking tape to wrap up the trigger mechanism. Now you have to warm up the barreled receiver. I used my kitchen oven with the door open. Just lay it on the rack with the barrel in the oven and the receiver sticking out, then switch it around with the receiver in and the barrel sticking out. CAUTION: You are only bringing the metal to slightly above room temperature, so don't leave it in there long. The metal should only be slightly warm. If it feels too warm, let it cool down a little. Once you have the metal slightly warm, you are ready to apply the finish.
APPLYING THE FINISH AND BAKING:
Shake the aerosol can for a minute or two to completely mix the contents. The instructions are on the can, but I will tell you to spray lightly with the can not too close to the metal. Don't worry about total coverage, as you will be applying two coats. After you have put the first coat on, DON'T FORGET TO TAKE THE TAPE AND OTHER THINGS OFF! Wait 30 minutes before putting it in the vertical oven. This is a good time to fire up the oven. Set the oven on top of the camp stove, directly above the burner. I use the electric fence wire to wrap around the stove pipe and fasten it to something on each end. This prevents the oven from falling over. With the stove pipe cap on and the thermometer inserted, fire up the camp stove. It will take awhile to bring the temperature up to the 300 degrees that you want, and some playing around to maintain that temperature, but it is not really all that difficult. Once you get the oven up to temperature and at least 30 minutes have passed since you applied the finish, you are ready to place the barreled receiver in the oven. I used a short section of coat hanger to hook onto the receiver bolt that goes in the tang. The other end of the coat hanger attaches to the short piece of coat hanger previously installed between the two eye hooks on the inside of the stove pipe cap. Using handle on the stove pipe cap, lift your suspended barreled receiver and insert it slowly down into the stove pipe. You may want to temporarily pull the shaft of the thermometer out some, so that it doesn't interfere, but once the barreled receiver is in, insert it back in to accurately monitor the temperature. The temperature you are trying to maintain is 300 degrees for 30 minutes. Don't worry about a little fluctuation, as there is bound to be some. After 30 minutes, shut the campstove off. It will take a long time for the metal to cool down, maybe an hour or more. When the metal is just warm to the touch, like it was when you applied the first coat, protect the areas that need it and apply the second coat paying attention to areas that need more coverage. Wait another 30 minutes, fire up the camp stove, and follow the previous instructions again.
CONCLUSION:
This is really harder to describe than it is to do. Just use common sense and take your time. I have done three rifles and they all turned out fine. Good luck, and if you have any further questions, please don't hesitate to ask.
