You might have read in my build thread to watch the ZdB facebook page for some exciting (to me at least ;) ) news. For anyone interested in the backstory, here it is. For those that don't care...there's pics at the bottom.

Several times a week for months and months (a year?) I search Craigslist for "lathe" "cnc" and "mill". About 4 weeks ago I hit jackpot. I searched for a different term (bridgeport?) and found a week old ad that didn't show up with any of my standard search terms. The description wasn't very detailed and had no pics. I emailed and got a response a few days later along with some pictures.

A fellow close to me (5 miles away) was selling a 3 axis CNC that had sat in storage for 9 years asking $1500. I imagined super rusty ground to a halt machinery sitting in a wet storage closet worth only it's weight (all 3500lbs) in scrap iron. Turns out, storage meant his front garage. After his son quit drag racing he ended his machine shop business as it only existing to fun the race team. There was surface rust on the exposed ways, but everything underneath and covered by a skirt was still shiny, greasy, and turned over easily by hand with no funny noises or hesitation. The controller is old (maybe I shouldn't say old, it's the same age as me give or take :p ) but I've done my research and found ways to bypass the manual inputs and, as a last resort, put in new electronics for ~$1000. When I got to his house he also had a 5 position turret lathe for $650. His front garage was crammed full like a pack rat. I was pretty sure I wanted it, but needed time.

After showing me the tools he said "come on, I want to show you something". He took me to the back garage and I knew I wanted the machines. There sat a tube frame Willy's in a deep royal blue that was imaculate. Up front sat a monster engine with a massive intake strapped to the top. The craftmanship was top notch, the garage was clean and organized. It was clear he took care of his stuff and the machines only looked old due to 9 years of condensation and dust.

I talked him down to $1800. Actually, I said "my wife told me I could only spend $1800. I didn't mention the part where I said "honey, I need you to tell me I can only spend $1800 so I'm not telling lies". :D I rented a drop deck trailer for $68, bought a come-a-long from harbor freight, and loaded up on straps, roller pipe, and other knick knacks. 10 hours of work later I had both machines in my garage. Of course, I had to spend 5 hours cleaning the garage up and throwing things away to make space, but it's so worth it.

What does this mean?

1: My wife is cooler than your wife. Not quite sure if she is? My wife told me I could have a CNC in the garage. How many CNC's are in your garage? (if you have more than one...well, then your wife is pretty cool too :) ) Winner winner chicken dinner!

2: I can eventually (once I clean it up) make some parts at home. Want a custom logo on the rear of your trans block off plate? Need a 1-off part? Instead of needing to add a middle man (machine shop) and buy a minimum of 10 parts (to kind of keep costs down) I can do things at home. Where before it wasn't feasible to have a shop make 2 or 3 units I can write programs and keep them on the ready to make parts as needed (this is great for me so I won't be sitting on $1000 worth of parts that may or may not sell).

Almost forgot a picture of the engine in the willy's.

That is awesome! I'm going to start lurking on Craigslist to see if I can do the same.

I think your wife might be cooler than mine, but I'm going to check to make sure.

That is really great. Nice find. Hmmm...now I need to start thinking of custom parts I "need"...

First order of business: suitable gas pedal mount!

Congrats on the pick up.

That's good news for many of us so now I'll look for stuff you can make and sell to pay for the CNC. Will it cut steel or just aluminum?

Since I cut tool steel with this:

... I'm pretty sure a full-size Bridgeport will have no problem.

It's all about the speeds and feeds. ;) It's a very beefy system (~3,500 lbs) and very rigid.

What a bargain, great find.

mills are cheap... tooling is expensive. Just be careful and don't break anything :D

BTW, that's why I have a tiny Sherline mill instead of a full size one. End mills are like five bucks a piece, and the entire CNC conversion cost me half of what the power supply for a real CNC system runs. I only have two downsides - it takes forever to finish something because I typically cut at a depth of 0.015 in steel, and my maximum part size is fairly limited.

Your wife is indeed cool, as are you for pursuing this and finding that old, heavy, top-quality equipment and refurbishing it. You'll be glad you made the effort.

I almost went with a grizzly g0704 and converted it to cnc but it would have cost more than this and not been as suitable for higher volumes of parts. For personal use i could have run it slow and been fine.

Looks awesome Craig, great find. Refurbishing old equipment makes you feel good too! My lathe came out of an old shoeshop in Lewiston Maine. It ran off a leather belt driven by the Androskoggin river, it is more than 100 years old. It now uses an old three speed tractor transmission and an electric motor... :)

Now that is pretty cool too.

They have been using cast iron and brass for a long time! :) I worked in college motorizing old equipment from the mills to do new work in small shoe shops...

Nice find Mechie3. We all knew you would end up with a lathe in your garage at some point. Congratulations......now the limits are endless!!! Does your wife know this is only the beginning? I guess she does.
Have fun........ i guess thats a foregone conclusion.
My kit comes Tuesday!!!!!

OK so now I'm jealous! I thought building the car would start me down a road of endless projects but nooooooo it doesn't end there! You guys are doing far worse! I've already changed jobs where they have an in house machine shop. I think given some time I will be able to tinker (gotta start somewhere since I've never ran a CNC, mill, lathe).

I'm really just kidding because I'm loving every second of it! I never would have thought of having a job that might let me tinker.;)

I had never run a CNC prior to my current job. I did have some experience with a lathe and mill mostly just from fooling around, asking someone else questions. When we got the CNC only 1 guy here knew how to use a 2axis and manually program it. I learned the basics of 2 axis from use and then used the manual to learn how to use the 3 axis and then taught a few others. It's not as hard as it seems, just very intimidating due to the damage you can cause. Start without using tools, then move to tools and cut foam.

They let me use the stuff here because I get good at it with lots of practice. When it comes time for needing work related parts they come to me because they know I can get it done quickly.

oh, just saw your post.... You suck!! :) congrats. I'm still looking and trying to decide what to do. The problem with my wife is that she never says no.. :) sometimes I have to say, "are you crazy, we can't spend that much!" even if it is stuff for me... :)
congrats though, that's very cool.
