I've made my own Chipping Hammer out of a jackhammer bit and would like to temper it.

yup yup. just put your hand blocking the bolt from fully recocking but let it recock close to full. this will stop the sear from catching the bolt assembly and it will go full auto or just jam the sear down

Try going to a local Tool and die shop and have a few made.\nI am sure they can help you for a  reasanoble cost, \nIts very basic Machining.\n\npeace

Try posting a picture of the tool you've got so we can see what it is.

a hammer and some nails:)\nI would have to see the problem for myself, then would proceed to fixing the problem in a correct way.

No offense, but take it to a Professional. You will be better off. If you've got it "in your hands" there's a good possibility your frying it as I type this message.

go to a outdoor/sporting goods store and buy a sharping stone then just glide the blade along the stone but be careful not to cut your self!

A lathe, a drill press, and a milling machine would be a good start, although how you plan to use them when you don't even know the names for them is a bit of a mystery to me.  Try Harbor Freight or Northern Tools.\n\nhttp://www.harborfreight.com/\nhttp://www.northerntool.com/

I would agree with the provious answers, low wattage soldering pencil, rosin core solder, and practice first on a throwaway piece of some electronic circuit board.  If you overheat the board it can be damaged beyond repair.  To remove the solder use solder wick, a kind of copper braid made for this purpose.  This job is probably for more experienced hands than yours.

I dont think that you would be able to make spring steel at  home spring steel is made by heating steel to very high temp (1800 degrees?) and then cooling it very quickly usualy in oil

If you are handy with a hammer and you can buy it dirt cheap, why not? You will have to replace a lot of stuff like sheetrock but you can come out pretty good if the price is right and you have the time.\n\nIf it has already been done, then I would really scrutinize the repairs. And still want it cheap-----just in case!

There are ways to make wooden boards easier to break that are used to ensure that all get broken.  Putting them in the oven with a low temp to dry them out will make it easier but there is not much that can be done with concrete except using low quality concrete.  I have broken concrete with my hands twice and it is easy with confidence but it does hurt, you feel it when you are done.  Wood boards hurt too if you do it wrong and it is simply to check that you are using proper technique when striking.\n\nWhen striking many at a time, when you break the first and use your weight to keep the momentum of the strike going, the blocks help to break each other by their placement and by the technique which you are striking with.
