Make A Spring Tool Center Punch 

That's a good tip. (Unfortunately I have no tig welding equipment at my disposal) I was thinking to improve my own with part of a small concrete drill bit. (One with a tungsten tip, obviously :)) Since it's meant for punching concrete, I figure it might work well enough (: I have to say, the bicycle axle I used to make my punch - (I just sharpened a tip on one end) - holds up pretty well (even on hardened concrete / hard steel). But I do have to sharpen it every once in awhile. I left the back end blunt / flat. Turns out to be perfect to drive plugs into walls without damaging the paint (like you would risk when using a hammer) Probably gonna try and make one with chisel point one too. And one with a pin driver. For door hinges. (The original spring tools also come in different varieties)

@@iggysixx some hard steel rod is good... You can use also an old drill bit... For example... Or an old philips screwdriver.... Finding an old piece of a tungsten rod is not easy expecially if you don't have a tig welding machine I understand... But maybe you can have a friend have it... Or in any workshop... Ask them.

@@flaviop.3938 Yeah, screwdriver crossed my mind too - chrome-vanadium steel is pretty hard. I also have good experienced with hex keys / allen keys. Made a metal scribe out of one (cut off the short end, sharpened it like a pencil. It just stays razor sharp, even when scratching hardened steel) . The problem with a hex key is the shape. (It's hard to drill a hexagonal hole (: ) Gonna try a small concrete drill bit probably

I made one with jelly rubber, then made one with a spring and rubber over the spring and work's a treat
