Most everyone has called me Troll since high school so that is fine to address me by. I am East of Ottawa, Ontario, Canada. I was one of only two students to graduate with honours from our community College's 40 Week Machinist Program, (an experimental program to give students all the education of a Master Machinist less of course time served...) I developed an allergy to cutting fluid, and by graduation my left arm looked like hamburger from and including my 4th proximal Phalange (just beyond my wedding ring if I could have worn it... up my arm and encircling shoulder blade and pectoral, still, I got 3 job offers without interview or application, (Thanks to our teacher and another student who's uncle owned the local Engineering Supply. Pending, of course my skin clearing up... So, I never actually worked in the field. In my 60s now, and still remember a little of what we were taught. Rebuilding a 130 year old Barnes 4 1/2 Screw Cutting Machine, that was converted to electricity before I got it... If I can ever find a place to unpack the shipping container that holds my shop I think I'm going to try the Manual Shaper Plans that lead me here...

Welcome Troll, glad to have you here.

There are some very fine machinists here.
I get by with my machining, but you won't see me winning any machinist awards.

I have food allergies, and so alergic to gluten, all dairy products; in other words anything good, I am allergic to it, including beer.
Such is life.

We build model engines here, but there are many side interests that go on here too.

I was picking up an engine up north in CT, and went into a large shop, perhaps 25,000 sq.ft.
All sorts of machines were operating all at the same time.
I had to ask "What were we making?".
"Springs" he said.
Lots and lots of springs.
I imagine that is how it is with screw cutting machines too.

Well lucky we are in the "modern ages"--all kinds of fluids and latex and latex-free gloves, splash guards, etc. I am using a fluid mixt with water for CNC lathes and mills. I thot it would be dangerous to touch because it dissolves in water and of course, I thot it would go right thru your skin. HOwever, apparently that is not the case, or if it is, it is still some harmless material. Do you have a foto of your Barnes?

Hi Richard.
If I could find my Back Up hard drive I'm sure I have lots of Photos of her... But I did find 2. I'm not using the cheap QCTP in the photo, I found a dirt cheap Hardinge L18 with about 20 shop made tool holders to replace it. I do howeve have a bunch of videos of it on YouTube:

Hi Craig,
I used to live in Oakville as a child though about all I remember about it is that we had an orange living room...

Hi Pat,
Thanks!
I found on YouTube a guy who makes engines for RC model planes, and I would love to give that a go! When I get my old Barnes dialed in...
In the 1890s, as I understand it, most lathes didn't have the change gears or lead screws to be able to cut threads. I think the name of my lathe has more to do with its ability to do this, rather than it being designed for that industrial process. See my answer to Richard for photos and video.

Hi. Interesting lathe. The oldest I used (now with my Sister) was a 3 in swing small lathe sold to "hobbyists" in 1930s?? I believe my Grandfather bought it new. (Woolworths ??) but it may have been second hand? He mounted it on a treadle from a sewing machine. My Dad owned it, added motors up to 1/4 hp. I inherited it when hee passed on, then passed it to my Sister when I bought an 8in swing Chinese lathe... My Dad added a power feed to the saddle screw. The whole lathe was obviously a light-weight, as it would twist with heavier cuts.But with light cuts I made my first few engines.
Fun to own, but the newer machine does more, more accurately.

Thanks K2,
I would like to see some pics of your family's generational machine! Sounds awesome!!
I haven't got the definition of swing memorized yet, but mine will face a 9"dia. not sure if it can get a tool down the outside of that though , IIRC it will turn 22" between centres. The ways are ground out of what basically amounts to an I beam made to fit in a 6" x 6" square, top and bottom 1" thick, centre 3 1/2" thick, set back off centre by 1/2" to make room for the dual lead screws. A friend of mine who's asthma caused him to be removed from submariner service and back to Her Majesty's Royal Navy in 1975, told me that these were still in service in Submarine Machine shops as the treadle didn't affect silent running...
