Put reamer to barrel today!!!

[bigngreen]

I know I'll be angering the gods of the picture but I'm so jacked about this that I can't wait for a pic!
I've been working on this for a long time getting the right tools and gear together but Thursday the last tool I needed showed, a set of PT&G 270 cal reamer bushings. I decided to just go for it and I chucked up my good barrel for my first run at reaming, got it dialed in to the knats hinny and cut my tenon and threaded it for shouldering on a Savage action with the barrel timed up perfectly.
Zeroed my GTR reamer holder in the tool holder and loaded her up with Vipers Venom oil and ran it on in. Went back and forth for a while and ended up with what I think is a good first chamber. The test indicators look good and the finish looks great, no bore scope but the lands look like they are cut very concentric, spec brass fits like a glove with .0015 head spacing.
The reamer is for a tight 270 WSM set up for 150 Bergers and a Lawton barrel.
I just have to flip it around and install a Muscle brake and I'll get to see just how good of a job I really did but I'm feeling good about it for sure!

Bigngreen,

Congrats! I share your excitement.

My new Grizzly just arrived Fri and I spent all weekend with my son setting up, cleaning it, etc... I still have a ways to go before running the break-in and making sure everything is quid pro quo. But, I am really keen to chamber that first barrel.

Don't you just love it when a plan comes together !!!!

It will probably shoot better than any you ever had because of the care and precision.

Good shooting.

Man it is a blast isn't it.

I'm stoked about how it all went, getting the tenon setup and threaded was no big sweat but when it was time to run the reamer in I got a little sick, kinda like the first time you build a 400 HP tractor engine and can't remember torquing the rods
I made up a dummy round tonight to check and see just how good this chamber is going to be and all the specs are just what I was looking for, bullet placement is much better and the neck will require minimum resizing. If this thing shoots bug holes I'm done for, no one will be able to leave a rifle laying around without me molesting it

I'm sure glad I asked a bunch of questions and waited till I could get the right tools. Right now I have to drive out to my father in-laws to use the lathe but hopefully I can have a lathe installed at home by the end of the year barring me breaking something again once I have a lathe here then things will get interesting!!!!

Thanks to all the guys that shared info with me like J E Custom and Fitch and others I'm missing!

Next up a 338 RUM in a Brux barreled Savage nestled in a Stockade P-dog stock gun)

Good for you I am getting very close myself, just a few more things and I will be trying it.

Hmmmmm, a certified registered gun molester

Would that be a firearmophile?????gun) lightbulb

Great to hear. Pretty exiting ain't it.

I'll be sending ya some 160 class 0.658 bc brass tipped projectiles one of these first days. Then we may know what the bc actually is and if they shoot worth a squat.

Apartment living is killing me. The lathe is out on the balcony and spring here sux....... Only rooms in the place without carpet are the kitchen and bathroom. Wiffee wouldn't tollerate the lathe in either spot.

Lathe and drives are under a tarp. Ain't that the pits!!!!!

Tomorrow is a day off and expected to rain all day.

You peaked my intrest. May I ask which lathe you have, out on the balcony, instead of in a shop?

I'm more interested in the engineering feat of getting it up there. I had a heck of a time getting mine in the garage with a forklift that wouldn't clear the door.

I tried to pull rank on my wife not to long ago and it went about as well as expected, she's quite understanding in reality since she was raised by a gun nut and maker so her norm is gun parts strewn all over her counters. I'm gaining on getting my garage converted into a usable gunsmithing space, wiring is GTG for a lathe and most of the insulation is in just need to sheath it.

My brother is almost finished CNC'ing his mini mill, we test ran it on my dad Vanguard, it's now a longer action dad got a little concerned when he saw me and my bro hunkered over the mill and his rifle hanging out of it

I bought some 150 Ballistic tips a couple weeks ago and tinkered with them a little in prep for having some IWK's soon, the new chamber has them seated just below the neck for max Retumbo capacity gun)I'll get a PM tonight!

This one is pretty dinky. I stated as large as I could to get my little job done (prototyping) and small enough that "crashes", and I've had some, were nothing but dings, bumps and flying chuck wrench a time or two.

As we speak its being converted to CNC. This is the company secret. Probably never been done in this manner by anyone. At least I hope so. Ever hear of Lego Mindstorms NXT? ****'d if it doesn't work. With lots and lots of tinkering.......

Its a Harbor Freight 8" x 12" lathe. 44859. Took quite a bit of work and fuss to get it trued/centered/etc but she's spot on now as long as one chucks up between 0.185 to 0.301 round stock.

Next upgrade will be collets and auto feed then it will be a real Italian Screw Machine.

Curious'r, 'n curious'r! Sounds like you're happy with it keeping you busy.

If you were back before you got into this lathe, would you go with any other brand?

Knowing what I now know, which was zero knowledge back then, I would go with a different brand. However, I have no idea of which.

I had only one objective and still have only one objective. Making points to repoint bullets. Berger and others couldn't do it effectively but I'm driving by an different engine.

The first thing I did was getting it to turn the stock with 0.00000 run out. Ruined one set of jaws doing it but they're inexpensive. Once I learned how to do that she turned into a whole different machine.

The compound is pretty poor also. Converting to the Mindstorms CNC takes me pretty much out of the picture.

bigngreen is of a different mindset and can figure out all of that threading stuff. Calcs are way too much for me. Its much easier, for me, to program it.

Plus bng has help. I just turned myself loose in the garage with the thing and started making chips.

This model weight closer to 300 pounds than 200 and is a bit big for my working area. I'm thinking of moving it and getting a smaller one for my dinking around down the road aways.

I'm confident that there are better machines out there for a similar price. Little Machine Shop has one that they have branded.
