I am at a point where I get frustrated by parts sets. I stopped work one one I've had for a while because I was tired and frustrated. I am not OK with making a rifle that has flaws.
Here is an example of what I am trying to get across. I just now finished adding the lock bolts on that rifle. The side plate inlet was located fairly precisely. The lock inlet was also very precisely located. I only had to do minimal clean up to the parts and wood to get a good gap free fit. I had no latitude on either.
When it came time to locate the lock bolts things got interesting. On the mill, I leveled up on the side plate flat plain. That agreed with the butplate screws. It did not agree precisely with the lock plate molding. Pick your poison. I leveled up the side plate face in both axis. The center of the lock bolt was precisely located in the plate. A center was started. A hole then plunged through to the lock plate with a quality bit. Neither hole in the lock plate was well located. They both landed low, usable but low in the lock. The top bolt was to far back in the lock bolster. Sure I could have drilled between centers but the bolt would have been cockeyed on that lock plate. Most every step is a compromise of lesser evils on this parts set.
This the kind of nonsense that makes me recommend a Kibler kit to anyone who asks. For a beginner it save making a messed up rifle. Some beginners just give up on the hobby. I got a large quantity of new parts from such a person. By contrast, process of assembling a Kibler is fun and easy.
I am at at the point where I choose Kibler or a plank from now on. A plank is slow but precise. I do all the important steps on a milling machine. IF the blank is square it is easy to make parts line up correctly the first time. With an ordinary precarve you have a bunch of conflicting inconsistencies and no great way to select a reference plane. Add in some shrinkage and warping and it gets really hard.
For the heck of it I may try a Chambers parts set. I hear they are excellent.
I'd like to see a quality parts set for a late golden age flintlock. Maybe an Armstrong? Chambers and Kibler offer earlier guns only.
Regarding being process or result oriented, I am both. Making slow steady progress toward the goal is fine with me. If take 150 hours to make a nice rifle from a plank that is OK. If I spend 150 hours fixing and working around problems that is not OK.
I have wondered if a CNC mill be used to to program Gcode using a touch stylus. That seems like it would make it possible to make nice copies of historical guns.
I hope you will find this interesting.
This is not to do the internet one-up-manship or working class hero baloney or any condescending motivation like that.
Rather my following comments are about build philosophy and methodology. I hope you find it interesting.
A lot of what you mention sounds foreign to me.
Axis’s and planes, that stuff does not matter to me but then again it does, I guess.
What looks good is good. That’s as far as I go.
Maybe I build or am presently building flaws into the gun.
It’s interesting to me that you mention the buttplate screws agreeing with the side plate plain.
I don’t understand. This is foreign to me.
Maybe we are closer in philosophy than it appears.
I have actually thought about this often.
Building a 18th Century gun is a lot like herding cats.
The only thing that’s reasonably square is the bore. Sometimes, even that’s not square on a barrel with run out but you don’t see that like you used to.
On swamped barrel.....it’s not square. It has the taper and flare.
The stock.....
A blank, it’s not square.
Castings.....those jokers are not square, especially trigger guards.
Look plate and side plate......
On a rifle I’m working on now the sidle plate side is different that the lock plate side.
On the lock side, the tail of the lock kicks out.....
On the side plate side the plain matches the bore rather than the side flat. This makes it thinner.
It’s really asymmetrical.
I have often thought that a machinist minded or engineer minded person would really struggle with an 18th Century gun. Maybe it’s just how I do it.
There’s nothing on it that’s truly precise or square.
To me it’s like herding cats. As long as they head in a general direction.....
That’s OK.
I don’t have a milling machine. I primarily use a rasp and straight edge.
I do use a depth gauge a lot.
Maybe it’s just my inexperience.
I’m more of a seat of the pants type.....
What looks good is good.
I’m not talking about hokey stuff or poor workmanship.
Maybe I’m looking at this from more of an art aspect than a precision aspect?
