    Got an AMEC spade drill and did some boring. Took out 8" without much fuss. Put together a coolant setup with an aquarium pump. Worked pretty well we'll see how it holds up.

    Yes! One quickly learns to not stand facing the side of the chuck

    Aw,, come on. Who HASN'T stood in front of a lathe when a freshly lubed chuck is spun up for the first time??? [You get extra points if you can even taste it!]

    How about when you're boring a small hole at high speed with coolant, and you think you're ok, until it overtops the shoulder in your part an hits your 12" chuck...

    I wiped off the lightbults and window, left the rest.

    TouchDRO and glass scales Installed. Made a huge difference! A few things to clean up install wise. I wasnt too crazy about the cross slide placement but for the time being it should be fine.

    I really like the coolant gutter around the top of the apron, not present on my ATW, they rely on the large chip tray for drainage back to the sump. I suppose you'd need a lot of flood splashing around for it to be useful?

    Well ive been making a little money with the old gal. Not much...but enough that my wife hasn't complained about me tooling around in the garage anymore.

    I've been working with 17-4 stainless mostly. My spade drill gets through it with a little fuss but overall is getting the job done. I wish i could get a carbide blade for it. The HSS inserts dont seem to last too long without touching up. Im getting like 3' bored through 1.5" stock before i need to switch out.

    I picked up a 6 jaw to work with thinner tubing. Just a cheapo chinese model. It seems to keep .001" which is nice. Im considering putting 4 screws around the OD to make a ghetto set-tru of sorts. For right now its good enough.

    I wanted a boring bar that could get me 8" of depth. Instead of dropping big money on a finished bar i was able to find two .78"x13" blank carbide shanks on ebay. I was able to grind the profile into something resembling a useful shape. So far so good! Seems to take .015" accurate passes which i will take as a win in my book! I may try to figure out how to graft an indexable head over the outside of it. For now its "good enough."

    Big fan of the thru tool coolant, I've been using a couple thru coolant boring bars recently. Works a lot better than trying to tease the coolant nozzle around to get the jet into the workpiece and the chip flushing is effective. Your emulsion looks a lot less messy than the cutting oil I'm using.. it works great but being a lot more viscous it tends to throw blobs off the workpiece.

    You were my inspiration! That and when i got the ugly green paint off i had a dark gray like yours underneath.

    Do you have the same crazy high TPI feeds on your machine? Mine goes to 368tpi!

    I was thinking i might try making mine a little more....oily...and less watery. I think this stuff is way more of a coolant than a cutting aid. Could just be the concentration. Im sure there is a better product out there i just havent looked very hard.

    I spent a while thinking of that tradeoff also. I came down on cutting oil due to the relatively light duty, and convienence of not needing to maintain coolant- tramp oil or rust isn't a concern for instance.

    It is harder to clean up after though, takes a while to drain off the ways back to the sump. I'm not sure of the tradeoff of a racing stripe laid up your chest and glasses between emulsion vs cutting oil

    But maybe you're thinking of a thicker emulsion, not cutting oil...

    Yeah mine has the same! Mine was actually green in the beginning I think. I wanted a dark grey so I mixed black and white together to get the grey I have. the handles were 1985 Olds Cutlass left over from a car I painted years ago. My machine may be for sale in the future as I am getting to the age I don't want to leave it for my son to deal with. Going to be hard to do as this belonged to my Dad. If anyone reading this has an interest I will say I don't get on here every week. I'm not ready to price it yet, just trying to think ahead a little.
