I have a Chambers Golden Age lock that I installed on my Beck project.I can't seem to make it work like my Large Siler.I have a few problems,the first being the sparking.I have installed the flint bevel up and down.In the bevel down mode,the flint contacts the frizzen extremely high.It cycles through,but very little spark.In bevel up mode,it looks like it should work,but the frizzen tips open slightly,then the whole thing binds up.The jaws are smooth inside,and it will work the flint loose after a few tries.I have tried leather(thick and thin),and also thin lead.Maybe the flints are too short?I thought maybe longer flints in bevel up mode would strike higher?They are 3/4 inch,which is what I have been using forever.I think the frizzen may be too soft also.It scratches easily with a file.Advice/comments?
