I clamp the barrels. It seems to me the gun should be held in place and this takes more than just clamping the action. With the clamps in two places, it won't move when pressure is put on the butt end of the stock. I've only done around 25 guns, but have never used foil. I remove the trigger guard if there's no through bolt and make sure the screw bolt from the trigger plate to the top tang is TIGHT. Also the bolt going down from the top tang is TIGHT. If there's a through bolt make sure it's TIGHT. These are what keeps the stock tight against the receiver. Then a oily rag is tied tight against the wrist. I don't use foil and have never yet hurt a finish [ knock on wood ]. I let it heat about an hour and start bending. If it doesn't bend easy I give it another half hour. If a 1/2" is wanted, I go 3/4"- it usually springs back half way. All but two or three have sprung back. On a 1894 Remington it would bend but go right back to where it started. Tried it three different times- no luck. Sold that gun. I shoot old SxS's and like 3 1/4" DAH. All 10 guns are bent to the same diamentions. I've bent five or six through bolt modern O/U's for friends - all of them have sprung back about half way. Different woods react differently. Good luck- it's fun to put em where you want. Paul
