DD bought a parts gun with an absolutly excellent barrel. The gun was made crudly from parts of an original from the 1850 period and had a pine wood stock. I salvaged the original parts and DD came up with a nice l/h stock in hard maple so the gun iis being restored to a shooter. The barrel is 1 1/8" across the flats and DD always wanting to save money got a stock blank with a 15/16 inlet so I just spent the better part of a day scraping and sanding the barrel channel out to the right size, that 'el cost him. I replaced the broken tang with another original blank I had in stock. The barrel is ow inlet into the stock and the gun has been converted back to the original wedge with a wedge i had in the parts bin. The gun with the exception of a new l/h lock willl be all old parts from the 1850 period and wil be back to what it was when it came from the shop. I will post pictures as the work progresses and add a few notes on the restoration progress. Here is a start this is the tang blank cut threaded and fitted to the old barrel. The barrel was trimmed ad squared and rethreaded for the new breech plug. The threads are just like the original as they are one caliber long. Attachments:

Here is the barrel being scrape inlet for the larger barrel. The tool is a hand made scraper made from an old drill bit and tempered in lard. The channel was roughed in with a plane made from an old Sandusky cabinet router plane with a blade made from an old file. Attachments:

I collect old parts and a fellow who died last year in O'Neill was a muzzleloader from the 1950's and he had a shop full of old parts he got from Bannerman's and I bought the works so everything on the gun will either be hand made or willl be parts over 150 years old.

What ended up being the twist on that barrel? just curious to what kind of projectile it will be most suited for.

did they do a gain twist like that way back then?
I'm ignorant on all things ML much less old ML so I'm looking for a teaching moment here.

Gain twist was actually easier to do woth the old style rifing machines and is better suited for projectiles with short bearing surfaces. I will try and find a picture of an old rifling head and post it and then you will understand, but basicle the old machines were long wooden cylinders with the rifling cu in and they slid through boards with corresponding grooves. SO... as the cylinder turned in the boards the rifling head attached to the cylinder was pulled through the barrel and each pull throough cut ONE groove say a 1/2 thousands deep. 20 passes made a finished groove and then you moved the cylinder around one notch for the next groove and so on. A good man pulling an old time rifling machine could cut maybe 2 barrels a day and then the barrels were lapped and trued and finish profiled on the outside.

The Civil War Springfield musket (model 1861, I think) that they made so many of, was a 3 groove barrel, gain twist.

I think 1850's through 1870's was the hayday of gain twist barrels and mostly ended just after 1900 jmo Them that were still made were made as T/M's discribed.

Update, the gun is now in the white and I am waiting for DD to come make some final decisions. The darn stock DD bought on the cheap was so hard and so cross grained that I had to file it from square to rifle shaped. 2 days of filiing!!! Boy I'll bet DD is sure glad he didn't spend the extra money on a decent stock to start with! I will try and take some pictures to post tomoorrow.
