Action Bedding Step by Step
|Bedding methodsThere are six methods of action and/or barrel bedding in common usetoday.|
1. Full contact bedding of the action with the barrel floated.
2. Full contact bedding of the action and the barrel.
3. Full contact bedding of the action with a pressure-bearing pad forthe barrel.
4. Pillar bedding of the action with the barrel floated.
5. A full length aluminum action bedding block.
6. The action glued to the stock with the barrel floated.
I will deal with the first method listed above - bedding the actionand floating the barrel. This method gives the best results for most precisionhigh power rifles.
For some time now, rifles have been available from the various factorieswith their barrels floated, that is, with no contact between the barreland stock. Production constraints prevent the time required to properlybed the action. While the rifles available from most factories today aremore accurate than their owners, improvements can be made for those shooterscapable of using the increased accuracy.
Materials needed for action bedding:
1. Bedding compound (Marine Tex , Brownells, Acraglas or Steel Bed ,Devcon Plastic Steel, or similar epoxy)
2. Modeling clay
3. Masking tape
4. Three or four 8" elastic bands (for securing receiver while epoxyis curing)
5. Release agent (suitable for type of epoxy used)
6. Epoxy dyes (to color epoxy to match stock if desired)
7. Inletting tools or Dremel Moto-Tool
8. Coarse, medium and fine Sand paper
9. Stock vise or suitable holding fixture
10. Cleaner/degreaser (alcohol , Break Clean , grease-free electricalcontact cleaner or
11. Extra long headless action screws
12. Disposable container for mixing epoxy
13. Plastic zip-lock baggies [ for parts ]
|BEFORE BEGINNING - MAKE SURE RIFLE ISNOT LOADED !!!!Action Bedding - Step-by-Step:|
1. Begin by removing the action from the stock .
2. Remove the bolt, trigger assembly, safety and bolt stop from thereceiver .
3. If the trigger guard was not removed during removal of the actionremove it now .
4. Secure stock in vise or holding device.
5. Install long headless action screws into action.
6. Use Inletting tools to carefully remove material from barrel channeluntil barrel has 1/16Â” to 1/8Â” of clearance along its full length. Checkfit often and remove material slowly and evenly. Use fine sand paper tosmooth this area for latter finishing.
7. Slowly and carefully remove 1/16Â” of stock material from all areasin the stock that the receiver and recoil lug contact. All of the areasfrom which you remove material should remain rough so that the epoxy hasa better surface to adhere to.
8. Degrease receiver and recoil lug, and then do it again.
9. Apply 3 to 4 layers of masking tape to the front, sides and bottomof recoil lug, leaving the back of the lug free of tape.
10. Then apply 3 to 4 layers of tape to the rear surface of the tang.
11. Use masking tape to cover any area on the outside of your stockthat epoxy may get on.
12. Use the molding clay to fill in any screw or pin holes and any otherareas you donÂ’t want epoxy in such as the magazine cut-out in the receiverand the stock and the trigger cut-out in both.
13. Double check that you didnÂ’t miss any place that you need clay -epoxy is vary hard to remove!
14. At the point on the barrel that is even with the end of the stock,wrap masking tape around the barrel till you have about 1/16Â” of tape builtup to center the barrel in the channel while the epoxy dries.
15. Apply release agent to receiver and barrel. Let it set for a fewminutes then do it again. Be sure to cover the whole thing with a goodcoat!
16. Degrease all areas that you want epoxy to bond to. Make sure alldegreaser is dry before proceeding.
17. Read the directions on your epoxy for mixing and mix a generousamount. Mix more than you think you will need!
18. Apply a generous amount of epoxy to all areas of receiver and recoillug contact .
19. Carefully fit receiver into stock .
20. Wrap elastic bands around the receiver and stock and secure snugly.
21. Wait 24 to 48 hours for epoxy to cure!
22. After epoxy has cured remove elastic bands to free stock fromaction.
23. Remove receiver from stock. Sometimes a sharp whack with a rubbermallet is required to free the receiver.
24. Remove all clay and be sure screw and pin holes are clean!
25. Remove tape from receiver.
26. Remove all excess epoxy from stock.
27. Remove clay from stock .
28. Use tape to cover all epoxied areas then paint or seal barrel channel.
29. Remove long action screws.
30. Reinstall trigger, safety and bolt stop.
31. Use degreaser to clean complete action and barrel.
32. After barrel channel sealer or paint is dry you can reassemble rifleand test fire.
