Thanks Clinton! I've added your Barrel Rifling Tool to our Metalworking category, as well as to your builder page: Clinton's Homemade Tools. Your receipt:

Clinton Congratulation excellent jig .. :clapping: :rocker:
:hattip:
Great video, Clinton! Saw some pretty cool ideas.
I like that initial 'threading' thingy Clinton. The re-purposed what-ever-it-is :hattip:
Doc
Hi,
Yes, same for me, the threading idea is great, I will keep that, and also the way you flute your reamer is really inspiring, I didn't have the idea to weld it temporarily while grinding it, that's the idea !
And also your adjustable reamer with the set screw and bit welded at the bottom, that's also a great idea !
Thanks for that !
Christophe
(question what kind of welding do you use, is it MIG ?)
Ahhh, the coil winding tool. I wound a double spiral coil to be used as a cold water condenser using it. The coil is depicted briefly in the video.Quote:

Hi Clinton,
An awesome project, as well as an interesting and useful homemade tool! Your Barrel Rifling Tool is the 'Tool of the Week'!
You'll be receiving one of our official HomemadeTools.net T-shirts:
Attachment 2539
Let me know (via PM) your size, color choice, and mailing address. We'll get the shirt in the mail to you directly.
Congrats!
Ken
Poor man's rifling tool with FANTASTIC results! Very well done Clinton.
Great video. We'll done.

Hi Clinton,
This is a very clever and creative method that can be adapted to other projects. In addition, the slot cutting jig has given me another idea for how to cut a thin slot without using a surface grinder.

I'm working on an attachment for my angle grinder that will do crude machining work. The fixture depicted was a quick fix for what I wanted to accomplish. The accuracy was okay for the job. I think the idea could be really improved upon. Keep us posted as to what you come up with.Quote:

I might be able to use it. I have been watching the videos at the “The Tool and Die Guy” website by Phil Kerner (I became a lifetime member last year). Phil shows a technique that I want to use. However, his tool modification process requires a surface grinder to cut a thin and 0.25” deep horizontal slot into the front face of a typical surface gage (e.g., a Starrett No. 57A). This slot is used for a thin and slightly rounded piece of tool steel to be inserted into the slot and held by friction (high precision not needed but there must be only one high spot along the thin tool steel front). When this type of modified surface gage is used with a test dial indicator, it is possible to very accurately (within a few 0.0001”) test a machined object for being vertically square relative to the horizontal plane of a surface plate and provide measurements for machining (or grinding) to make it square.
I am looking for a way to grind the thin slot without using a surface grinder.
Thank you for your posting your ideas.
Paul
You've made a difficult choice, not easy to domine !
The first length of turn models as you made in metal were made in 18th wild parts of America in wood for the rifling of Kentucky or such flint rifles, it is a publication about that published on Historical Armmaking technology booklets.
This thread has been moved to the Must Read subforum. Congrats (and thanks) to Clinton for making such a valuable contribution!
Love the Idea and concept I was thinking a rifle button attached to some allthread in the same frame powered by a drill or hand crank ??? just thinking out loud:smash:
:headscratch:well I guess with no replies I am yapping to myself LoL crazy this can not be so hard a gun drill reamer with a spiral button drill bit with spines a twisted reamer somthing any machinists gun smith tinkers help aaaaaaahhhhhhhhhh lets make this tool
I've upgraded the rifling tool somewhat. Slightly easier on the back and the results are substantially better.

Funny you should mention that. Check my latest post. And apologies for not responding. I don't get on here much and don't seem to get emails when there's a post.Quote:

thanks this is my 1st gun club . i have a delta 3d printer and a tritium reactor ,
Congratulations on getting HMT of the week. Great video
Thank you for sharing

I am curous, is there a standard rate of twist or? If someone was to have it twist more per inch, would the projectile spin faster and be more accurate? Asking out of ignorance. Beautiful work!
Twist is a complicated relation between bullet weight, barrel length, caliper, distance to be accurate, you can have a .455 muzzle-loading rifle with a long twist which is more accurate than a rapid twist hunting .30 modern rifle, it's just a problem of what you want as result. ;-)
Here is some information on rate of twist.Quote:
