First build? Meaning from a blank? Tell us more about what you have done. Looks OK for a first, but you do have the front sight on backwards. The high end should face the eye.
Hi Starnes. Congratulations on your first build.
I agree with Larry that it would be good to know more to make suggestions specific to what type of rifle you were working toward.
Besides the front sight, I think your rear sight is on backwards as well.
A couple of generic comments for your consideration:
1. It's "aggressive" to try to do decorations like carving, beavertails, moldings, etc. on a very first try. These types of decorative elements have their own learning curve, so sometimes, unless one has obtained these skills elsewhere, it can be best to focus on the basic rifle build first. Most of us certainly appreciate the works of art that are displayed on this forum, but a very well executed "plain" gun is a beauty to behold....simple and elegant.
2. Sometimes it is hard to tell from pictures because of the angle of the photo, but it looks like there is a convex "swoop up" on the top line of the barrel channel from the nose cap. The nose cap appears to come up about 1/2 way on the barrel. While it varies on the type/school of rifle, if the wood then jumps up to only reveal about the top third of the side flat, that is probably too much wood which could have been taken down from nose cap to lock to provide for a slimmer appearance of the forestock and a clean line front to back.
3. Cleanup: Areas around the carving and other features could be cleaned up with small files, etc. to get rid of "tool marks" and provide a more finished appearance.
4. "Edges" where there shouldn't be any. Pictures are really great tools during the build process. I think that they can reveal things that just looking at the gun with the naked eye can miss. I know that's the case for me. For instance, in the first picture of the second set of pictures showing the lollipop tang, there appears to be a "flat" on both sides of the tang, and more so on the left side than the right.
See how the light shines on that flat and makes a defined "line" where it then drops off and down the sides? That "edge" along the light may show too "abrupt" of a change that could be lightly worked to get a smoother transition that is even on both sides. Take pictures as you go and use the light on the stock to "see" things you might need to address along the way.
5. Again, pictures are difficult to decipher sometimes, but it looks like the comb of your butt plate points "down", then the wood comes back up a little before curving back down toward the nose. It might be just the way the picture was taken. While the top line of the comb of the buttstock can take any number of shapes depending on the style of rifle, it should integrate into the direction that top line is taking where the two meet. If you lay a straight edge on the buttplate comb, does that top line "flow" into the continued direction of the wood top line of the comb at the junction of the two?
The above suggestions are clearly cosmetic and with a little more time and patience could provide a cleaner result. A lot of the fun of building is adding to one's skills for the next one! It's good to see that you jumped in and started building. That's the main thing. As has been said many times here...all builders make some mistakes, it's how they fix them that makes the difference!
Would also like to know how it shoots! In the end, putting the round ball on target is what really counts, so look forward to seeing how the load workup and shooting goes.
