Lakefield MarkII, trigger parts???

[fox fire]

  I tried to improve the trigger on a old Lake field MarkII,  it was feelin a lot better BUT,,,I took to much of and now when you close the bolt it dry fires before it's closed.     I've looked at Numricks site and they didnt have any parts for it, to me the gun looks like a older savage so it got me to wunderin if ya'll knew if any parts would trade out. (providing that any parts are available)    If I cant find any parts my friend can probably build it up with a heliarc then I can rework it.   I'm not a trained gun smith but just tryin to learn and make a few improvements to a older gun for fun so any info is greatly appreciated.    THANX YA'LL

Most of these older rifles and some of the currently made guns use case hordened parts. If you cut through that thin layer of hardened steel the sear will fail quickly. Heliarc does a good job of building up parts such as yours assuming the operator is skilled and chromoly wire is used. If built up with mild steel it'l have to be case hardened with a material such as "CaseNit" (sp.) available from Brownells.. I'm not familiar with the model you are talking about so can't speak to whether or not any parts will interchange, but I strongly doubt that such would work.

   Your probably rite about the parts trade'n out,  as far as be'in case hardened I have no idea, I never knew you could "do it yer self case harden."   This is the main reson I bought this gun was to learn to do basic up grades my self, so no matter what happens I gettin benifit from it,rite.    My friend told me today he had a heliarc at home and he's got a lot of talent for this stuff so I sure he can doctor it up, but as far as case harden'n goes,,, any body tell me how technicol it is and whats required to do it rite???   The gun, I can fix even if I have to fab out another piece just to get it in shootin shape, it's a good older rifle but it's also my guinnea pig, at this piont I'm tyin to get the trigger pull down, it breaks good and clean ( or it did anyway ) but it was serious hard to pull to the point of fire'n.

CaseNit is very easy to use. It's a powder and the part to be cased is heated to a bright red color and plunged into the powder. It will fuse to the metal and an even coat is prefered. The process is repeated(I like at least twice) and the part is heated the last time and plunged ionto water. If you had it hot enough the coating of powder will shatter off and the metal's surface will be a dull grayish color. It should also be as hard as woodpecker lips.. On small parts the metal won't want to retain enough heat to fuse the powder and they can be done by submersing the part to be treated in a small pile of powder in a spoon or ladle and fusing the whole mess.. When it glows quite red the water bath will shatter it clean.. Always wear safety gear as hot metal and fused powder can fly about and if the part is small it is possible to get it too hard and make it brittle. Also if the part is carbon steel it may harden without the case powder and the water bath may crack or over harden the part. I would build the part up and grind/file to shape before any hardening. Test the part by heating and quenching to determine the effect of the casenit.. The procedure is shown on the can the casrnit comes in.
