Lathe Height
Is there any safety reason for the standard height rule of "elbow height"
when setting up a lathe on a bench or stand. Is there a some safety issues involve. I will be doing some light spindle work a couple times a month for only an hour or so and I have a nice workbench for the lathe. The lathe on the bench will result in the lathe spindle being about 4-5 inches higher than elbow height.... Any real problem here?? Is the lathe more dangerous at this level than at elbow level. -Thanks |

If the lathe is too low, you will get a tired back from bending over. If it is too high, you will not be able to steady the tool handles easily against the side of your body, under your arm. If you find that your lathe is too high, just build yourself a platform to stand on--easier than building a whole new bench. |

Thank you Mac and thank you Leo..... Just wanted to touch base with people
in the know. I didn't think you could predict with any certainty the direction of the accident. I couldn't really think of any safety issues but thought I would get a second opinion.... in this case.... two opinions is enough for me. -thanks again. "buck" wrote in message ervers.com...

If the work decides to part company with the lathe it could go in any
direction. Some would say that by having your head closer to the lathe means it's more dangerous because you would be hit harder, but lets face it 4 or 5 inches isn't going to make much difference to the velocity of the projectile. As others have said, I think lathe height comes down to comfort and they have based it on the height of the average man.

I really didn't have any choice on how high my lathe (jet Mini) would be; it
sits on my workbench. So, I built a sturdy and wide stand to raise me up to the 'comfortable' height. fwiw Tom -- Remove the 'p' from 'shaw' to e-mail me. "Paulco" wrote in message ...

I tried that, but hit concrete, raising the lathe was cheaper then
getting a jackhammer. ;-) James www.cryscom.nb.ca mac davis wrote: On Mon, 15 Nov 2004 07:50:05 GMT, "Tom Storey" wrote: I really didn't have any choice on how high my lathe (jet Mini) would be; it sits on my workbench.

Posted it because: (a) the operating height seems very high compared to what we're used to these days (or he may be sitting, the easier to use the treadle), and (b) The turner seems to be using what we sometimes assume is a modern development - a bowl saver.

The photo is a (fairly) famous photo from The Wellington Journal &
Shrewsbury News, published 8.5.1937. The following description of the photo is from "The Reading Lathe" by P.H. Dixon: "Robert ("Jack") Jordan, the Wellington, Sallop, turner exhibiting a nest of bowls on a lathe...Note that, for photographic purposes, he is holding his turning tool well above its correct place on the toolrest (the end of which may be seen on top of the tailstock), when the tool would not have been visible." This was a common way to photograph, and earlier draw, turners at work... and is by no means indicative of the way they actually worked. The lathe is also clearly a common pole lathe, not a treadle lathe. The leather belt passes three times around the bowl mandrel, which is spiked into what will be the hollow of the nest of bowls and is supported by the massive tailstock, seen in front of Mr. Jordan's chest. The English turners called these "bowl saver" tools "hook tools" and actually had small hooks forged on the ends in order to shear-cut the core from the bowl, unlike most modern coring systems which scrape to make this cut. Shearing takes much less energy than does scraping, very important on a foot-powered lathe.

You may feel some fatigue or sensation in the shoulder--if so, you may need to stand on a platform. A face shield is very inexpensive insurance. |

As Leo said. But, another thing to think about...
Imagine this... Hold a tool comfortably and imagine the spindle in front of you. As the spindle gets higher (or you get lower which is easier to picture) you need to lower the tool rest to keep a reasonable cutting angle. Typically, tool rests will not go very far below the center of the spindle and this is especially true for the mini machines. So, you are going to be turning in some pretty awkward positions. That said, many prefer the spindle an inch or two above the elbow. Bill In article , says... "buck" wrote: (clip) Is the lathe more dangerous at this level than at elbow level.

That's made a rather nice photograph a bit more special. John |
