Anyone good at bending a Bolt?

I have a old Mauser rifle with a straight bolt. Didn't pay much for the gun, but I'm thinking about putting a scope on the gun, and it will require the bolt to be bent down.

Anyone know of anyone who does this and does it well? I'm not willing to put a torch to it and locking it in a vice myself and bending it down.

I had a fella bend and polish my Nagant bolt, and it turned out really nice!! He even put a pull ring on it. He had an Ebay ad and his name was Max Shepperd I believe. It only cost around $50.

You're wise for not doing it yourself. The bolt should be annealed and re-tempered so that it won't become brittle, and break. Then a good polishing for esthetic's.

Haven't done anything yet, its still sitting in my gun safe.

I'm really considering just buying a spare bolt, heating it up, bending it, and throwing it in water.

My grandfather was a welder by trade. He told me after they had put heat to tempered steel, they cooled the part down in transmission fluid to help keep its temper.

You can temper metal with water.

Some of the machinist I've talked to/worked with use oil for some metals and water for others. I believe pre-heat treated steel would be fine in water but a standard mild steel would work better in oil to help keep the surface from getting brittle.

If you're serious about annealing and stress relieving it, you can get an old toaster over and heat to maximum heat, add the bolt until it gets to it's hottest temp, then lower the heat by 100 degrees every 45 minutes until it gets down to 200 or so, then take it out to cool down. Of course, this is after you've welded on it.
