I did not read everyones inputs just now,so I don't know if i maybe missed it,but what kind of wire do you use for making springs......spring wire????
Piano wire.
Is it possible for you to remove the wire from the tin and place it on a shaft and allow it to pay off in a "rolling" fashion?
If anyone knows how I can make this possible, much appreciated! I could imagine creating some kind of larger canister, if that would help. But the thing about the canister is that it stops the wire from expanding outwards, by holding it inwards by the external wall of the canister. If I cut the straps holding the 500g could together when it is not already in the canister, it will I believe explode into a mass of tangled spaghetti-like mess. I have no idea how I could put it on a roll, due to this (its tendency to want to expand to a very large curvature). Any ideas?
feed the wire from the bottom or outside of the roll not the inside.
Have you ever used these 500g coils and canisters? They are designed for the wire to come out of the central hole, I don't think there is any option to change that. The wire can't come out another way it seems.
And feed to the bottom of your mandrel. (It may work from top of roll to top of mandrel but I am not sure)
I would think bottom-bottom and top-top would be the same. But I do get the principle of not reversing the curvature - basically winding large coils onto mandril to make smaller coils, in the same plane, right? I'll try to make that setup really aligned on my next attempt. But I guess I might have to replace the canister with something? Like a bigger canister, maybe three times the diameter or something? Do you think that might help?
I'm going to disagree with Jubil on one point, yes take the spring wire from the outside of a spool, not the inside of that can, but go from bottom of spool to top of mandrel or vice-versa, the reverse of the existing curvature seems to make windings a better fit (or does for me when winding transformer coils etc.)
Oh, ok reverse the curvature? Is this a hot topic, or do people have success with both? Or do each have specific advantages and disadvantages? And, several people have said to take the wire from the outside. But, with a 500g could of wire that has no spool, how to I set up a spool? I can imagine winding it onto a spool somehow but wouldn't it just try its best to unravel? With great force? Or is there some proceedure? If anyone has any vids or pics to show how I can do this, that would be great!
Or, if spools of good wire for this already exist, can anyone give me any link to where to buy? (UK would be best but even if elsewhere at least I can see what you guys mean). Smallest possible that would still work would be good, to save on costs. I don't fancy having to buy like 10kg of wire or something, if that's avoidable!
Many thanks guys
