I don't know if you got my answer or not?

The best place to answer a question on a topic that is in public view like this one is, is to answer the question in the topic.
Sending someone an answer by PM does no one any good.

You didn't say what the trouble is or what needs tuning. Is the lock producing a lot of sparks? If it isn't, chances are the flint is the problem.

I beg to0 differ, I said what the problem is, If I knew what needs to be done to the lock, I wouldn't have asked the question, As far as public view I made no attempt to answer by hiding any answer. If I broke protocol it was not my intention.

Not seeing where you say what the problem is that you are having? Lack spark? Slow firing? Pan primer fall out? Mushy main spring?

Hi Tom,
There is not a lot you can do to tune a Lyman flintlock because of the coil springs. A big part of tuning is balancing the the force of the mainspring and frizzen springs. On Lyman locks you really can only adjust the frizzen spring. Usually a lock works best if the force needed to open the frizzen is about 30-50% of that needed to pull the flintcock back from rest to full cock. I give a wide range there because I am finding the geometry of the lock affects that ratio and the geometry of Lyman locks is not the best. You can polish all the bearing surfaces, which will help a little but the lock will never feel smooth because of the coil springs. Polishing the top leaf of the frizzen spring where the frizzen toe rides on it will also help. Also keep that spot lubed with a little grease.

Watching this tread! I just bought a Lyman Trade flinter and am about to use it as a club.

Hello Tom, I say tinker with it take it apart smooth any burrs that are on the parts.
I had semi decent results with just the basic grooming on a late model T/C lock.
I found out by using a Pedrosoli frizzen or Lyman frizzen and grinding the toe of the frizzen it can be more consistent. Not up to a level of an L&R or another custom lock but it does reduce the frustrations involved. And can be used until you decide to upgrade.
I agree with Dave you can only do so much.
