    Copy of an original blunderbuss

    I had a little time between business trips to look at the barrel again and make some decisions about proof testing. The first thing I realized is that I didn't really like the profile of the new barrel. I had taken the easy way out and, in cutting the outside taper, I had just used the...

    Pathfinder, Yes…..I test rocket engines for a living…. So I will fire this barrel electrically from a safe distance….😉 Brokennock, I think you are correct that a lot of the powder charge would burn in the air outside of the barrel. We will see.

    Copy of an original blunderbuss

    Just for fun I put 600 grains of FFg in the bore. It filled the 7 bore (0.875 in this case) between the two blue tape marks....i.e. the brass showing between the two pieces of tape is the length of the bore filled with 600 grains of powder. Looks a little excessive to me.....but what do I know...

    I found an old chart in a 1972 Dixie Gun Works catalog that had some Belgian service and proof charges. The service charge was 158 grains behind a 7 gage round ball but the proof charge was over 500 grains !!! I like the idea of perhaps 180 to 200 grains as the proof charge behind 3 oz of shot...

    I will need to proof this barrel before I go too far with the build. It is a 7 bore. It's made out of better material than the original (I'm fairly sure) and the bore is slightly smaller (i.e. thicker walls), so it should be fine. However, anyone know what a 7 bore proof charge should be ...

    Got the brass barrel finish machined today. Here are a few photos....Drilling, reaming, sculpting the muzzle, etc. Will need to make the breach plug and lugs next.

    Noeyebrows, This is the brass colored silver solder I use. Color match is good and it tarnishes like the brass as well. https://www.riogrande.com/product/brass-wire-solder-20-ga/132201GP/?code=132201...

    Back in town for a bit and wanted to get a few more things done. Prepared the drill for drilling the bore. Knocked back the cutting edge to a 90 degree rake angle...... Started the prep on the trigger guard casting........Had to use some brass colored silver solder to patch a couple of...

    Copy of an original blunderbuss

    Ground as it is now, with a positive rake to the cutting edges, the drill will grab and dig in deeper than it should…. Especially since I have drilled a pilot hole and the center point of the drill will not do any cutting. I will use a stone and very slightly flatten both cutting edges so that...

    The new bore drill arrived finally from Drills & Cutters in Florida...bad timing on my part to order the drill a few days before the latest hurricane blew into their neck of the woods. However, it made it here safely. Now I need to modify the drill for use on brass. I will be out of the shop...

    A little more work on the barrel today. Finished drilling the pilot through with a long 1/2" drill. Then bored the breach for a 1 1/8-12 breach plug and tapped it. Waiting now for a long bore size drill to finish the bore.

    Gathering parts that are close to the original. Here is the original lock compared to one of Chamber's English fowler locks..... Some options for the trigger guard....... The guard with the acorn finial is a little too big in the bow and the bow is too narrow. I will go with the...

    Back in 2016 I was commissioned to build a brass barreled blunderbuss. Here is the link to the original posts https://www.muzzleloadingforum.com/threads/blunderbuss.103402/ The fellow who I made this for has contacted me again about a smaller version. He happened across an original...

    Finishing a walnut stock...

    Doc, Any finish I have ever used (and I have tried a lot of them) has ALWAYS dried better in the sun. The UV in sunlight rapidly kicks over the cross linking required to get most finishes to dry completely. I actually use what I call a "stock rotisserie". I like to dry stains and finishes in...

    Full scale cannon re-build

    Well, as luck would have it I had a partial emergency arise on the 4th and missed the chance to fire the complete gun that evening.....will make another run at it on New Year's Eve... ;) Nonetheless, here are photos of the now completed rebuild project.....prolonge, loading implements, stop...

    Full scale cannon re-build

    The firing will look like this for a couple of years ago....... I did have a neighborhood audience a couple of years ago who loudly vocalized the part of the 1812 overture just before the first cannon firing at the top of their lungs......they paused for a second and then I punctuated their...
