Yesterday when printing I noticed that the usual sound of the trip springs on my SP-15 seemed different/quieter. Upon examining, I found that the spring on the operator’s side is no longer fitting snugly under what is referred to as “Dowel B” on sheet #302 “SP Series Replacement Trip Spring” diagram that Paul has posted here previously. There is some play when I gently push down on the end of the spring. The other trip spring is still fitting properly under the dowel. I’m assuming that the loose spring is on its way to breaking and should be replaced.
Since both springs were broken when I first got the press, I know what’s involved with replacing them, but I’m wondering if there’s any underlying issue I should look for that would cause the one spring to be weakening. In the 4 years since the springs were replaced with new ones, I’d say that the press has received light to medium usage. Is it normal for the springs to wear out periodically? Thanks for any insights.
