I have been fighting with (and losing to) a broken spring from a spool. The metal has snapped close to the Plastic spigot thingy (I know it will have a proper name like "plastic nut thing). It seems that all I need to do is drill a hole in the metal spring to reattach, but what on earth do you have to use to get through thiss metal!!!!!!!!!!HELP

If you have a stand mounted drill and a sharp drill bit it shouldn't be too much of a problem.

If you don't have access to a workshop with a turret drill try putting a block of wood close to the width of the spring in the base of a vice then place the spring on this. You will be able to apply much more pressure and it should get through.

Spring steel is highly temper steel and try drilling it will heat it up and cause it to become brittle. You need to take it to a machine shop and have them punch a new hole in it for you. If you try drilling it will just break again.

How big is the hole that you need?

I am not so sure that if you start with a small pilot hole (using a sharp drill and a cutting lubricant) that you will not be OK.

However, I do have to admit that I have never tried it!

UM!!! All seems highly complicated, perhaps I should just get another spring:(

As a armourer of 30 years experience believe me I have done it with pilot holes and lubicate under water to keep the heat down.
Any decent machine shop can punch a new hole in it without a problem.

Use a pillar /engineering drill, with a tungsten tiped drill, with the spring backed up on a piece of hard wood or soft metal, use plenty of lubricating oil and you can drill a new hole in the spring.
