Inlet tool

[shootrj2003]

 It seems that it may take a week or so to get a nice 15/16” barrel inlet tool from gun line ,if they answer my email.it seems to me I could forge an old file and grind and file a 15/16” octagon profile on it  for a scraper in a few minutes  instead of waiting ,I’m not impatient just not interested in wasting time ( that’s not the same thing to me)is the difference worth waiting for and should it be the exact size of the channel or a size smaller?I am an accomplished blacksmith/ farrier .The gunline tool looks like a nice tool too though.

A barrel inletting  scraper can also be made from a cut off chunk of an old/rusty 15/16" octagon barrel (jes' sayin')

Can also be made from a 15/16" paddle bit ground off

If you have experience making tools, go for it. However, I would mic the barrel just in case it is over or undersize and then make the cutter a smidge(.010-.015) smaller than the barrel. That way you can little by little open up the channel to get a perfect fit for the barrel.
I did something similar and finished sizing the channel with an undersize wood half octagon stick,wrapped with 220 grit sandpaper.
This is just what I came up with and I’m sure there are other ways, but it did a nice job.

I need the old rusty barrel for the inlet that I’m making!( I did think about hacking just a little off the muzzle but thought better of it) ( lol!) Seriously,I bought a cheap Chinese file at ace hardware to make a barrel inlet scraper from then stopped at a friends junk store and he gave me a piece of steel for free  and I can figure if I want to make a really good one or what ,10-4 on keep it slightly undersize that’s why I asked ,I read somewhere a guy suggested if you want a certain size to buy the next size smaller,thought  I would ask. The paddle bit was the first thing I grabbed however, the file however is long enough to bend the tang up for a handle and when you anneal the file also drill another hole for a smaller ball handle like a plane and use both hands for control .

These are what I tried to explain in above post.

 [ Invalid Attachment ]  [ Invalid Attachment ] Nicely made sanding blocks made one from a file that scrapes,after I figure the sharpengangle,I thought of you’s a then you could glue stops of sandpaper on just one flat if there was a flat with a problem thanks.I gave up on mine first then a few days later ground the edge a different angl and wallah! Mine is more expensive no doubt.

Good tool to have!

I have some "channel scrapers" that I made many years ago that our very similar to yours. I use them when (and after) chiseling out a barrel channel. They work pretty darn good.

It would appear our scraping edge (as you draw your tool towards you) is the same as mine. I've found that a good straight edge is also a very useful tool to check the channel when scraping.

That something I did not think about,the straight edge.thanks
