I have had a few TC Locks and have not been really impressed with the sparks they throw. I replaced my one Renegade lock with an L&R and Can't say enough about the performance of that thing. It really works good but I have another Renegade that I built from a kit and didn't want to cut into the stock. So today I tried a Lyman Frizzen after reading some of the posts on here. My TC lock is an older one. I had to drill out the frizzen hole to 9/64" and grind down the sides of the tab where the hole is to get it to fit in my lock. I also had to grind back the pivot point where it rides on the spring to get it to stay tight over the pan.
I had sent this lock back to Thompson a few years back to have it looked at because it was not sparking and they installed a new frizzen. I think it actually worked worse after they got done with it. When I was installing the Lyman frizzen, it was loose when it pivoted. I came to find out that the frizzen spring was catching on the lock plate and needed a little bit of relief to flex freely.
After that and the slight adjustment to the pivot point, I'm getting lots of spark and I am very happy with the Lyman frizzen. I would recommend this mod if you are not happy with your TC lock performance and you don't want to bore out your stock for the L&R lock.
The early TC locks(top)did more smashing than shaving.They were replaced with more symmictrical ones.(Bottom)I still have some of both. Pictures by t410er, on Flickr
It also helps to clean the frizzen with alcohol and use a good flint of Black English,French Amber,or American Chert. Pictures 227 by t410er, on Flickr
With these flints I'm getting around 80 shots.If dulled in the field I can do a reverse knap and get about 10 more shots.
Keep the flints about 1/16"-1/32" from the frizzen.
The answers to all of life's questions are found in the Bible!
Thanks, 410-er. It seems that I have a renegade with the "old" style lock.. It eats flints and will hardly spark at all now. I'm having a Lyman frizzen put on it and hoping that gets me through flintlock season.
Question on the L&R's: How is your trigger pull on those after fitting them to your TC's. I installed on on my Firestorm in the off season and mine is terrible. Measures over 8 lbs. I'm half tempted to put the TC lock back on as it still does fit; although not perfectly anymore due to my sloppy inlaying work.
My L&R is on a Renegade with a set trigger. I want to install one on a single trigger and was wondering about the trigger pull. The Lyman frizzen is easy to fit. Took me less than an hour but a good piece of that was working with my frizzen spring.
I took mine to the range today to test out the lock. I'm not to happy to report that it does not work on my gun. I figured it might be a problem after installation that the touch hole did not line up perfectly with the pan. After a few misfires where the pan burned but didn't fire the charge, I took it off and luckily the old lock still works. I believe the lock I purchased was for a hawkin or renegade but was supposed to be compatable to the firestorm. It isn't. If anyone is looking for this model pm me.
