Well i figured id start a new thread.
Before I get into details. A little about myself, I went to school for precesion machine tool at warren tech. I spent 2.5 years there learning everything from basic manual mills, lathes, and surface grinders to edm machines, cnc machines, and even a breif crash course in plastic injection molding. I was taught everything I know by an old school master tool and die maker. Since then I've worked in the industry as a cnc operator in a production shop.
However I soon discovered the best way to kill a good hobby is to make it your job.
Ok actually production cnc gets extremely repetitive and boring. I fell asleep and got canned.
Went into automotive machining and eventually became a mechanic. Ive been in automotive for about 10 years now.
A few years ago I purchased a harbor freight 8x12 (14) lathe at a swap meet to support my other hobby, road racing. I've been wanting a mill ever since. But old iron is limited and expensive here in Colorado.
So i began looking into what started as the harbor freight round column rf45 clone. That eventually snowballed into a drastically reduced tooling budget and more machine. I stumbled upon a charter oak 12z mill. After moderate research I chose the 12z and placed a deposit. I ordered the machine while out of stock back on october 1st. Paul did give me a discount due to the item being out of stock.
Due to unfortunate shipping problems to no fault of charter oak I'm expecting to get my new mill late November but more likely early December. So you can expect to see some pictures in the coming months. But ill say right now not expecting to make chips right away. This was the absolute top of my budget and there isn't much of anything left for tooling right now.
After I recover from buying the mill ill be buying tooling to go with it.
Stay tuned for updates!

Waiting for months due to unfortunate shipping problems is just part of getting machinery, Chris. Welcome to the forum.

Chris, it was a pleasure meeting you and yakking the afternoon away. :)

Looking forward to your impressions and progress reports after receiving your new toy. You mentioned that you built your stand a bit taller than mine. Are you going to shorten it or just try it first and see how it works for you? You're about 6'4" IIRC.

Ah yes, the waiting game. A confusing mix of excitement and frustration. Welcome to the club!

Don't forget to put up a pic of the stand you built, we all like pictures.

Yes definetly I look forward to doing it again sometime! For the stand im going to leave it as is for now. And see how it goes. Worst case I will take the casters off and lower it down via the leveling feet. That should get me around 35 inches from the floor. And yes of course there will be many pictures and progress reports along the way.

That stand height looks like it could be fine, maybe 8 inches higher than my old stand which was too low for me and I'm 5'7". Design wise the 12z weighs a 1/2 ton and those leveling pads are way out to the sides, could be a bit springy but it looks like you used pretty thick tubing. My Kubota tractor front end loader lifted my G4003G lathe up onto its stand without any problem, but it couldn't budge the 12z more than 3 inches off the pallet its that heavy.

Thanks. The table of the stand is built from 2"x3" 11 gauge rectangle tubing. The legs and lower frame are 2" 11 gauge square tubing. Caster plates are made from 1/4" plate and the mounts for the leveling feet are made from 4" long sections of 2" square tubing ( scrap from the legs) it was cut at an angle length wise and 1/4 plate was welded to the bottom.
Initially I was going to copy charter oaks design for the leveling feet. But decided to take a different approach.
Charter oaks design places all of the load on the welded nut inside the down tubes something that is not serviceable. This design I came up with places the load on the leveling foot and lower nut. All serviceable parts.

Btw bill,
11/10/15 happy birthday.

Yea, the 'spec sheet brigade' here will tell you the mill weighs less than 800 lbs., but they've not even touched one. Shipping weight on mine with the stand strapped to the top was around 1200 lbs. And I could press the stand over my head no problem, even for an Old Guy. ;)

You've seen my mill. It ain't no slouch.

BTW, didn't tell you I twisted wrenches for a few years. All the ASE certs, and Master level on MB and LR. Didn't bother with the Porsche certs as I hated working on those little things with these big paws... :(

No you didn't mention it. And actually I don't have any ase certs I always worked in dealers before this job so I got factory certs instead. Now I work in fleet maintenance for a private company so it's not required.

I was told it couldn't be done, so I took all of the tests for the basic ASE certs at one time. Passed them all. :)

Last dealer I worked at carried Mercedes, Land Rover, and Porsche. My stainless tool boxes and work benches were built into the wall. Compressed air, oil, and water hoses came down from the ceiling between my two lifts. Brick floors that we had to scrub every week. The owner had a lot of money in that dealership. :eek:

But twisting wrenches is a young mans game.

Yeah that's bs, at least it is these days. Ase anymore is for independent repair shops so customers will feel comfortable there all the manufacturers have their own training programs some will even send you to fancy schools like wyo tech etc for free. Then have you sign a contract stating they basically own you for 5 yrs.

This is a couple pictures of some other equipment in my home shop. Jd2 model 32 hydro tubing bender 9e573883c8ed3db3e24b629627ccfccf.jpg 0300f7636e4cad7010aea7ad67ef4b98.jpg 3d595c6f6c91d31de1967bd9b936fd05.jpg 3f126664db6f815b5802fbe97e44ef91.jpg 16e855fc182e56b62a99385af5585463.jpg

The base of the stand is also custom built, it is 1" square tube welded with casters and 1/2" bolts coming up to level the upper portion of the stand it is hydraulic so all bending forces are contained in the frame of the bender. This lets me have it mobile so i can pull it out in the driveway bend a tube, then put it away in the corner instead of bolting to the floor in a fixed location.

Yeah I believe I was in elementary or middle school then. Back in the days of flux core mig welders electrical conduit and goped motorized go karts.
Too many ideas too stupid to know better. As a kid I put a 5hp briggs on a big wheel scooter from wal mart. The sprocket mount was an old skill saw blade welded to a driveshaft. Yeah I shoulda died a few times..
